Questions and Answers
  • 1. 

    1. Which two statements are true regarding link-state routing protocols? (Choose two.)

    • A.

      They do not work well in networks that require special heirarchical designs.

    • B.

      They are aware of the complete network topology.

    • C.

      They pass their entire routing tables to their directly connected neighbors only.

    • D.

      They offer rapid convergence times in large networks.

    • E.

      They rely on decreasing hop counts to determine the best path.

    Correct Answer(s)
    B. They are aware of the complete network topology.
    D. They offer rapid convergence times in large networks.
    Explanation
    Link-state routing protocols are aware of the complete network topology, meaning they have information about all the routers and links in the network. This allows them to make more informed routing decisions based on the current state of the network. Additionally, link-state routing protocols offer rapid convergence times in large networks, meaning they can quickly adapt to changes in the network and update their routing tables accordingly. This is important in large networks where changes can occur frequently, ensuring that the network continues to operate efficiently.

  • 2. 

    2. Which three statements about routing protocols are true? (Choose three.)

    • A.

      OSPF elects designated routers on multiaccess links.

    • B.

      RIP does not support classless routing.

    • C.

      EIGRP supports unequal cost load balancing.

    • D.

      EIGRP uses broadcast traffic to establish adjacencies with its neighbors.

    • E.

      RIP does not advertise a route beyond a hop count of 15.

    Correct Answer(s)
    A. OSPF elects designated routers on multiaccess links.
    C. EIGRP supports unequal cost load balancing.
    E. RIP does not advertise a route beyond a hop count of 15.
    Explanation
    OSPF elects designated routers on multiaccess links. This means that in an OSPF network, one router is elected as the designated router (DR) and another as the backup designated router (BDR) to handle the routing updates for that network segment. This helps in reducing the amount of routing information exchanged and improves network efficiency.

    EIGRP supports unequal cost load balancing. EIGRP allows for load balancing across multiple paths, even if they have different costs. This helps in optimizing network traffic distribution and improving overall network performance.

    RIP does not advertise a route beyond a hop count of 15. RIP (Routing Information Protocol) has a maximum hop count of 15, which means that it will not advertise or consider routes that are more than 15 hops away. This limitation prevents routing loops and ensures that the network remains stable.

    Rate this question:

  • 3. 

    What does RIP use to reduce convergence time in a larger network?

    • A.

      It reduces the update timer to 15 seconds if there are more then 10 routes.

    • B.

      It uses triggered updates to announce network changes if they happen in between the periodic updates.

    • C.

      It uses random pings to detect if a pathway is down and therefore is preemptive on finding networks that are down.

    • D.

      It uses multicast instead of broadcast to send routing updates.

    Correct Answer
    B. It uses triggered updates to announce network changes if they happen in between the periodic updates.
    Explanation
    RIP uses triggered updates to announce network changes if they happen in between the periodic updates. This means that if a network change occurs, such as a link going down, RIP will immediately send an update to inform other routers about the change. This helps to reduce convergence time in larger networks because routers can quickly adjust their routing tables to account for the change, rather than waiting for the next periodic update.

      All of the routers are connected to Montgomery through an Ethernet switch.

    • C.

      Montgomery has Layer 2 connectivity with Cumberland.

    • D.

      Layer 3 connectivity is operational for all of the devices listed in the Device ID column.

    • E.

      Brant, Fisherman, and Potomac are directly connected to Montgomery.

    Correct Answer(s)
    C. Montgomery has Layer 2 connectivity with Cumberland.
    E. Brant, Fisherman, and Potomac are directly connected to Montgomery.
    Explanation
    The output shown in the exhibit indicates that Montgomery has Layer 2 connectivity with Cumberland because they are directly connected. Additionally, Brant, Fisherman, and Potomac are also directly connected to Montgomery, as stated in the exhibit.

    Rate this question:

  • 5. 

    5. Refer to the exhibit. The results of the show ip route command are displayed in the graphic for Router R2. Which route will be selected for a packet with a destination address of 10.1.4.1?

    • A.

      Static route to 10.1.0.0/22

    • B.

      RIP route to 10.1.0.0/23

    • C.

      RIP route to 10.1.0.0/24

    • D.

      0.0.0.0/0 via 192.168.0.1

    Correct Answer
    D. 0.0.0.0/0 via 192.168.0.1
    Explanation
    The correct answer is 0.0.0.0/0 via 192.168.0.1. This is the default route, also known as the gateway of last resort. It is used when there is no specific route in the routing table for the destination address of the packet. In this case, since there is no specific route for the destination address of 10.1.4.1, the default route will be selected. The packet will be forwarded to the next hop IP address 192.168.0.1, which is the gateway for all unknown destinations.

    Rate this question:

  • 6. 

    6. Refer to the exhibit. All router interfaces are configured with an IP address and are operational. If no routing protocols or static routes are configured, what information will be included in the show ip route command output for router A?

    • A.

      All of the 192.168.x.0 networks will be in the routing table.

    • B.

      Routes to networks 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 will be in the routing table.

    • C.

      The routing table will be empty because routes and dynamic routes have not been configured.

    • D.

      A default route is automatically installed in the routing table to allow connectivity between the networks.

    Correct Answer
    B. Routes to networks 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 will be in the routing table.
    Explanation
    If no routing protocols or static routes are configured, the only routes that will be included in the show ip route command output for router A are the directly connected networks. In this case, the router interfaces are configured with IP addresses in the 192.168.x.0 range, so the routes to networks 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 will be in the routing table.

    Rate this question:

  • 7. 

    7. Which of the following should be considered when troubleshooting a problem with the establishment of neighbor relationships between OSPF routers? (Choose three.)

    • A.

      OSPF interval timers mismatch

    • B.

      Gateway of last resort not redistributed

    • C.

      Interface network type mismatch

    • D.

      No loopback interface configured

    • E.

      Inconsistent authentication configuration

    Correct Answer(s)
    A. OSPF interval timers mismatch
    C. Interface network type mismatch
    E. Inconsistent authentication configuration
    Explanation
    When troubleshooting a problem with the establishment of neighbor relationships between OSPF routers, three factors should be considered. First, an OSPF interval timers mismatch can cause issues with neighbor relationships, as routers need to have the same interval timers to communicate effectively. Second, an interface network type mismatch can also prevent the establishment of neighbor relationships, as routers must have the same network type configured on their interfaces. Lastly, inconsistent authentication configuration can cause problems, as routers need to have the same authentication settings to authenticate and establish neighbor relationships.

    8. Refer to the exhibit. A network administrator is trying to figure out why BOS does not have the 10.0.0.0/24 network in its routing table. All routers are configured for OSPF in area 0. The links between the routers are operational and the administrator is able to pingbetween all router interfaces. What is a logical next step that the network administrator should take to troubleshoot the problem?

    • A.

      Reboot the routers.

    • B.

      Change the OSPF process ID on all of the routers to 0.

    • C.

      Check to see if the cable is loose between BOS and JAX.

    • D.

      Check to see if CDP packets are passing between the routers.

    • E.

      Show and debug commands to determine if hellos are propagating.

    Correct Answer
    E. Show and debug commands to determine if hellos are propagating.
    Explanation
    The network administrator should use show and debug commands to determine if OSPF hello packets are propagating between the routers. This will help identify if there is an issue with the OSPF neighbor relationship between BOS and the other routers. By analyzing the output of these commands, the administrator can verify if the routers are exchanging hello packets and if there are any errors or inconsistencies in the OSPF adjacency. This step will provide valuable information to troubleshoot why BOS does not have the 10.0.0.0/24 network in its routing table.

    Rate this question:

    • B.

      192.168.10.5 and 192.168.10.9 are feasible successors

    • C.

      Neighbors 192.168.10.9 and 192.168.10.5 have auto summary disabled

    • D.

      Router 3 is load balancing traffic to the 172.16.3.0 network across its serial interfaces

    • E.

      All interfaces shown on Router3 are in the passive state and will not send EIGRP advertisements

    Correct Answer(s)
    C. Neighbors 192.168.10.9 and 192.168.10.5 have auto summary disabled
    D. Router 3 is load balancing traffic to the 172.16.3.0 network across its serial interfaces
    Explanation
    Based on the output shown, the two true statements are:

    1. "neighbors 192.168.10.9 and 192.168.10.5 have auto summary disabled": This means that the neighbors with IP addresses 192.168.10.9 and 192.168.10.5 have disabled the auto summarization feature in their EIGRP configurations.

    2. "router 3 is load balancing traffic to the 172.16.3.0 network across its serial interfaces": This indicates that Router3 is distributing or balancing the traffic destined for the 172.16.3.0 network across its serial interfaces, possibly to optimize performance or utilize available bandwidth.

    Rate this question:

  • 10. 

    10. The network shown in the diagram is having problems routing traffic. It is suspected that the problem is with the addressing scheme. What is the problem with the addressing used in the topology?

    • A.

      The address assigned to the Ethernet0 interface of Router1 is a broadcast address for that subnetwork.

    • B.

      The subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3.

    • C.

      The subnetwork assigned to the Serial0 interface of Router1 is on a different subnetwork from the address for Serial0 of Router2.

    • D.

      The subnetwork assigned to Ethernet0 of Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3.

    Correct Answer
    B. The subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3.
    Explanation
    The problem with the addressing used in the topology is that the subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3. This can cause routing issues as the overlapping subnetworks can lead to confusion in routing traffic between the two routers.

    11. What is the function of the OSPF LSU packet?

    • A.

      Used to confirm receipt of certain types of OSPF packets

    • B.

      Used to establish and maintain adjacency with other OSPF routers

    • C.

      Used to request more information about any entry in the BDR

    • D.

      Used to announce new OSPF information and to reply to certain types of requests

    Correct Answer
    D. Used to announce new OSPF information and to reply to certain types of requests
    Explanation
    The OSPF LSU (Link State Update) packet is used to announce new OSPF information and to reply to certain types of requests. This packet is responsible for flooding the network with information about the state of OSPF routers and their links. It is used to update the OSPF database and synchronize the routing tables of OSPF routers within an area. Additionally, the LSU packet can be used to respond to requests for specific OSPF information from other routers.

  • 12. 

    12. Which of the following are primary functions of a router? (Choose two.)

    • A.

      Packet switching

    • B.

      Microsegmentation

    • C.

      Domain name resolution

    • D.

      Path selection

    • E.

      Flow control

    Correct Answer(s)
    A. Packet switching
    D. Path selection
    Explanation
    A router is a networking device that connects multiple networks together. One of its primary functions is packet switching, which involves receiving data packets from one network and forwarding them to the appropriate network based on their destination IP address. This allows for efficient and effective data transmission across different networks. Another primary function of a router is path selection, where it determines the best path or route for data packets to travel from the source network to the destination network. By selecting the most optimal path, routers ensure that data reaches its intended destination in a timely manner.

    14. What is the first step OSPF and IS-IS routers take in building a shortest path first database?

    • A.

      Learn about directly connected networks

    • B.

      Send hello to discover neighbors and form adjacencies

    • C.

      Choose successors and feasible successors to populate the topology table

    • D.

      Flood LSPs to all neighbors informing them of all known networks and their link states

    Correct Answer
    A. Learn about directly connected networks
    Explanation
    The first step OSPF and IS-IS routers take in building a shortest path first database is to learn about directly connected networks. This means that the routers gather information about the networks that are directly connected to them, such as their IP addresses and network masks. This information is then used to calculate the shortest path to each network and populate the shortest path first database.

    Rate this question:

  • 15. 

    15. Which three statements describe the operation of routing with EIGRP? (Choose three.)

    • A.

      As new neighbors are discovered, entries are placed in a neighbor table.

    • B.

      If the feasible successor has a higher advertised cost than the current successor route, then it becomes the primary route.

    • C.

      Hello packets are not received within the hold time, DUAL must recalculate the topology.

    • D.

      The reported distance is the distance to a destination as advertised by a neighbor.

    • E.

      EIGRP maintains full knowledge of the network topology in the topology table and exchanges full routing information with neighboring routers in every update.

    Correct Answer(s)
    A. As new neighbors are discovered, entries are placed in a neighbor table.
    C. Hello packets are not received within the hold time, DUAL must recalculate the topology.
    D. The reported distance is the distance to a destination as advertised by a neighbor.
    Explanation
    The first statement is correct because when new neighbors are discovered, their information is stored in a neighbor table to keep track of the available routes.

    The second statement is correct because if a feasible successor route has a higher advertised cost than the current successor route, it becomes the primary route.

    The third statement is correct because if hello packets are not received within the hold time, the DUAL (Diffusing Update Algorithm) must recalculate the network topology.

    These three statements accurately describe the operation of routing with EIGRP.

    • A.

      Router_A(config-router)# ospf redistribute default-route

    • B.

      Router_B(config-router)# ospf redistribute default-route

    • C.

      Router_A(config-router)# default-information originate

    • D.

      Router_B(config-router)# default-information originate

    • E.

      Router_A(config-router)# ip ospf update-default

    Correct Answer
    C. Router_A(config-router)# default-information originate
    Explanation
    The command "Router_A(config-router)# default-information originate" will save the administrator the time and trouble of configuring the default route on Router_B and all of the other routers in the OSPF area. This command allows Router_A to advertise the default route to the other routers in the OSPF area, ensuring that they have a route to any destination not explicitly defined in their routing tables.

    17. Which of the following are required when adding a network to the OSPF routing process configuration? (Choose three.)

    • A.

      Network address

    • B.

      Loopback address

    • C.

      Subnet mask

    • D.

      Wildcard mask

    • E.

      Area ID

    Correct Answer(s)
    A. Network address
    D. Wildcard mask
    E. Area ID
    Explanation
    When adding a network to the OSPF routing process configuration, three things are required. The network address is needed to specify the network that will be included in the OSPF routing process. The wildcard mask is used to determine which specific IP addresses within the network will be included. Lastly, the area ID is required to identify the OSPF area to which the network will belong.

    Rate this question:

  • 18. 

    18. A network administrator has enabled RIP on routers B and C in the network diagram. Which of the following commands will prevent RIP updates from being sent to Router A?

    • A.

      A(config)# router rip A(config-router)# passive-interface S0/0

    • B.

      B(config)# router rip B(config-router)# network 192.168.25.48 B(config-router)# network 192.168.25.64

    • C.

      A(config)# router rip A(config-router)# no network 192.168.25.32

    • D.

      B(config)# router rip B(config-router)# passive-interface S0/0

    • E.

      A(config)# no router rip

    Correct Answer
    D. B(config)# router rip B(config-router)# passive-interface S0/0
    Explanation
    The correct answer is B(config)# router rip
    B(config-router)# passive-interface S0/0. This command configures the interface S0/0 on Router B as a passive interface for RIP. Passive interfaces do not send or receive routing updates, so by configuring S0/0 as a passive interface, RIP updates will not be sent to Router A.

    Rate this question:

  • 19. 

    19. Which statement is true regarding routing metrics?

    • A.

      All routing protocols use the same metrics.

    • B.

      EIGRP uses bandwidth as its only metric.

    • C.

      Routers compare metrics to determine the best route.

    • D.

      The larger metric generally represents the better path.

    Correct Answer
    C. Routers compare metrics to determine the best route.
    Explanation
    Routers compare metrics to determine the best route. Routing metrics are values used by routers to determine the optimal path for forwarding network traffic. Different routing protocols use different metrics to make this decision. By comparing these metrics, routers can choose the route with the lowest metric value, which typically represents the best path. This allows routers to efficiently route traffic through the network based on factors such as bandwidth, delay, reliability, or cost.

  • 20. 

    20. Refer to the exhibit. The network is running the RIP routing protocol. Network 10.0.0.0 goes down. Which statement is true regarding how the routers in this topology will respond to this event?

    • A.

      Router4 will learn about the failed route 30 seconds later in the next periodic update.

    • B.

      Split horizon will prevent Router4 from fowarding packets to the 10.0.0.0 network until the holddown timer expires.

    • C.

      Router5 immediately flushes the unreachable route from its routing table.

    • D.

      Router5 will send Router4 a triggered update with a metric of 16 for network 10.0.0.0.

    Correct Answer
    D. Router5 will send Router4 a triggered update with a metric of 16 for network 10.0.0.0.
    Explanation
    When network 10.0.0.0 goes down, Router5 will immediately send Router4 a triggered update with a metric of 16 for network 10.0.0.0. This is because RIP uses hop count as its metric, and a metric of 16 indicates that the network is unreachable. This triggered update is sent right away to inform Router4 about the failure, rather than waiting for the next periodic update.

  • 21. 

    21. What command would the network administrator apply to a router that is running OSPF to advertise the entire range of addresses included in 172.16.0.0/19 in area 0?

    • A.

      R1(config-router)# network 172.16.0.0 0.0.0.255 area 0

    • B.

      R1(config-router)# network 172.16.0.0 0.0.3.255 area 0

    • C.

      R1(config-router)# network 172.16.0.0 0.0.15.255 area 0

    • D.

      R1(config-router)# network 172.16.0.0 0.0.31.255 area 0

    Correct Answer
    D. R1(config-router)# network 172.16.0.0 0.0.31.255 area 0
    Explanation
    The correct answer is R1(config-router)# network 172.16.0.0 0.0.31.255 area 0. This command is used to advertise the entire range of addresses included in the 172.16.0.0/19 network in area 0 of OSPF. The wildcard mask 0.0.31.255 is used to specify the range of addresses to be advertised.

    Rate this question:

  • 23. 

    23. Refer to the exhibit. What will happen if interface Serial0/0/1 goes down on Router1?

    • A.

      The Dijkstra algorithm will calculate the feasible successor.

    • B.

      DUAL will query neighbors for a route to network 192.168.1.0.

    • C.

      Neighbor 172.16.3.2 will be promoted to the feasible successor.

    • D.

      Traffic destined to the 192.168.1.0 network will be dropped immediately due to lack of a feasible successor.

    Correct Answer
    B. DUAL will query neighbors for a route to network 192.168.1.0.
    Explanation
    If interface Serial0/0/1 goes down on Router1, DUAL (Diffusing Update Algorithm) will query its neighbors for an alternative route to reach the network 192.168.1.0. This is because DUAL is the algorithm used by Cisco routers to calculate the best path to a destination network. When a link failure occurs, DUAL will search for a feasible successor, which is a backup route that meets certain criteria. In this case, DUAL will query the neighbors to find a new route to the network 192.168.1.0.

    • A.

      The packet will be dropped.

    • B.

      The packet will be forwarded to the gateway of last resort.

    • C.

      The packet will match the 192.168.0.0 network and be forwarded out Serial 0/0.

    • D.

      The packet will most closely match the 192.168.0.8 subnet and be forwarded out Serial 0/1.

    Correct Answer
    A. The packet will be dropped.
    Explanation
    When the command "no ip classless" is issued on Router1, it means that the router will no longer perform classless routing. This means that the router will only forward packets to destinations that fall within directly connected networks. In this case, the packet is destined for host 192.168.0.26, which is not within a directly connected network of Router1. Therefore, the router will not have a route to forward the packet and it will be dropped.

    25. Which three statements are true regarding the encapsulation and de-encapsulation of packets when traveling through a router? (Choose three.)

    • A.

      The router modifies the TTL field, decrementing it by one.

    • B.

      The router changes the source IP to the IP of the exit interface.

    • C.

      The router maintains the same source and destination IP.

    • D.

      The router changes the source physical address to the physical address of the exit interface.

    • E.

      The router changes the destination IP to the IP of the exit interface.

    Correct Answer(s)
    A. The router modifies the TTL field, decrementing it by one.
    C. The router maintains the same source and destination IP.
    D. The router changes the source pHysical address to the pHysical address of the exit interface.
    Explanation
    When a packet travels through a router, the TTL (Time-to-Live) field in the packet header is modified by decrementing it by one. This is done to prevent packets from circulating indefinitely in the network. The router also maintains the same source and destination IP addresses, ensuring that the packet reaches its intended destination. Additionally, the router changes the source physical address to the physical address of the exit interface. This is necessary as the packet leaves the router and enters a different network segment. Therefore, the three true statements regarding the encapsulation and de-encapsulation of packets when traveling through a router are: the router modifies the TTL field, the router maintains the same source and destination IP, and the router changes the source physical address.

    27. What are two tasks that must be completed before two routers can use OSPF to form a neighbor adjacency? (Choose two.)

    • A.

      The routers must elect a designated router.

    • B.

      The routers must agree on the network type.

    • C.

      The routers must use the same dead interval.

    • D.

      The routers must exchange link state requests.

    • E.

      The routers must exchange database description packets.

    Correct Answer(s)
    B. The routers must agree on the network type.
    C. The routers must use the same dead interval.
    Explanation
    Before two routers can use OSPF to form a neighbor adjacency, they must agree on the network type. This is important because OSPF supports different network types such as point-to-point, broadcast, and non-broadcast multi-access. The routers must also use the same dead interval, which is the time interval after which a router considers a neighbor to be dead if it hasn't received any OSPF messages. This ensures that both routers have the same timing for detecting and handling neighbor failures.

    28. Refer to the exhibit. The network is using the RIPv2 routing protocol. If network 10.0.0.0 goes down, what mechanism will prevent Router1 from advertising false routing information back to Router2?

    • A.

      Triggered updates

    • B.

      Poison reverse

    • C.

      Holddown timers

    • D.

      Split horizon

    Correct Answer
    C. Holddown timers
    Explanation
    Holddown timers are used in routing protocols to prevent the advertisement of false routing information. When a route goes down, the holddown timer is activated, during which the router will not accept any updates regarding that route. This prevents the router from quickly advertising incorrect or inconsistent routing information. In this scenario, if network 10.0.0.0 goes down, the holddown timer will prevent Router1 from immediately advertising this change to Router2, ensuring that accurate routing information is maintained.

    29. Refer to the exhibit. R1 knows two routes, Path A and Path B, to the Ethernet network attached to R3. R1 learned Path A to network 10.2.0.0/16 from a static route and Path B to network 10.2.0.0/16 from EIGRP. Which route will R1 install in its routing table?

    • A.

      Both routes are installed and load balancing occurs across both paths.

    • B.

      The route via Path B is installed because the EIGRP route has the best metric to network 10.2.0.0/16.

    • C.

      The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16.

    • D.

      The route via Path B is installed because the EIGRP route has the lowest administrative distance to network 10.2.0.0/16.

    • E.

      The route via Path A is installed because the static route has the lowest administrative distance to network 10.2.0.0/16.

    Correct Answer
    C. The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16.
    Explanation
    The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16. In this scenario, R1 has learned two routes to the Ethernet network attached to R3 - Path A from a static route and Path B from EIGRP. The metric of a route determines its preference, and in this case, the static route has a better metric compared to the EIGRP route. Therefore, R1 will install the route via Path A in its routing table.
