Refer to the exhibit. The output of the show ip route command for three routers on anetwork is displayed. All routers are operational, pings are not blocked on this network,and no default routes are installed. Which two pings will fail? (Choose two.)
- A.
From R1 to 172.16.1.1
- B.
From R1 to 192.168.3.1
- C.
From R2 to 192.168.1.1
- D.
From R2 to 192.168.3.1
- E.
From R3 to 192.168.1.1
Correct Answer(s)
B. From R1 to 192.168.3.1
E. From R3 to 192.168.1.1Explanation
The two pings that will fail are from R1 to 192.168.3.1 and from R3 to 192.168.1.1. This can be determined by analyzing the output of the "show ip route" command for each router. From R1, there is no specific route for the 192.168.3.0/24 network, so the ping to 192.168.3.1 will fail. From R3, there is no specific route for the 192.168.1.0/24 network, so the ping to 192.168.1.1 will also fail.Rate this question:

A network administrator needs to configure a single router to loadbalance the traffic over unequal cost paths. Which routing protocol should the administrator use?
- A.
EIGRP
- B.
OSPF
- C.
RIPv1
- D.
RIPv2
Correct Answer
D. RIPv2Explanation
The network administrator should use RIPv2 to configure the single router to load balance the traffic over unequal cost paths. RIPv2 supports the use of multiple paths with different costs, allowing for load balancing. EIGRP and OSPF also support load balancing, but RIPv2 is a simpler and less resource-intensive option. RIPv1 does not support load balancing at all.Rate this question:

14. Refer to the exhibit. Both routers are using the RIP protocol. Devices on the 192.168.1.1 network can ping the S0/0/0 interface on R2 but cannot ping devices on the 192.168.2.1 network. What is a possible cause of this problem
- A.
The routers are configured with different versions of RIP
- B.
R2 is not forwarding the routing updates.
- C.
The R1 configuration should include the no autosummary command.
- D.
The maximum path number has been exceeded.
Correct Answer
A. The routers are configured with different versions of RIPExplanation
The possible cause of the problem is that the routers are configured with different versions of RIP. RIP version 1 and RIP version 2 are not compatible with each other. If R1 and R2 are using different versions of RIP, they will not be able to exchange routing information properly, leading to the inability to ping devices on the 192.168.2.1 network.Rate this question:

- B.
R 192.168.1.0/24 [120/2] via 192.168.200.1, 00:00:17, Serial 0/0/0
- C.
R 192.168.1.0/24 [120/1] via 192.168.100.1, 00:00:17, Serial 0/0/1
- D.
R 192.168.1.0/24 [120/4] via 192.168.101.1, 00:00:17, Serial 0/1/1
Correct Answer
C. R 192.168.1.0/24 [120/1] via 192.168.100.1, 00:00:17, Serial 0/0/1Explanation
The route with the lowest administrative distance will be installed in the routing table. In this case, all the routes have the same prefix length (24) and the same metric value (120), but they have different administrative distances. The route with the lowest administrative distance is [120/1] via 192.168.100.1, so it will be installed in the routing table.Rate this question:

Refer to the exhibit. A network administrator adds this command to router R1: ip route 192.168.2.0 255.255.255.0 S0/0/0. What is the result of adding this command?
- A.
This route is automatically propagated throughout the network.
- B.
The traffic for network 172.16.1.0 is forwarded to network 192.168.2.0
- C.
A static route is established
- D.
The traffic for all Class C networks is forwarded to 172.16.1.2.
Correct Answer
C. A static route is establishedExplanation
Adding the command "ip route 192.168.2.0 255.255.255.0 S0/0/0" to router R1 establishes a static route. A static route is a manually configured route that specifies the next-hop IP address or exit interface for a specific network. In this case, the command specifies that any traffic destined for the network 192.168.2.0 with a subnet mask of 255.255.255.0 should be forwarded out of the S0/0/0 interface of router R1. This allows the router to know how to reach the specified network and forward traffic accordingly.Rate this question:

Refer to the exhibit. The interfaces of all routers are configured for OSPF area 0. R3 can ping R1, but the two routers are unable to establish a neighbor adjacency. What should the network administrator do to troubleshoot this problem?
- A.
Check if the interfaces of the routers are enabled.
- B.
Check the hello and dead intervals between the routers.
- C.
Check the process ID of both routers
- D.
Check if CDP is enabled on all the routers.
Correct Answer
B. Check the hello and dead intervals between the routers.Explanation
To troubleshoot the problem of R3 and R1 not establishing a neighbor adjacency, the network administrator should check the hello and dead intervals between the routers. The hello interval determines how often OSPF routers send hello packets to discover and establish neighbor adjacencies. The dead interval is the time duration after which a router considers a neighbor to be unreachable if it does not receive any hello packets. By checking and adjusting these intervals, the network administrator can ensure that the routers are sending and receiving hello packets at the correct frequency, allowing them to establish a neighbor adjacency.Rate this question:
-
- 11.
Which three statements are true regarding the encapsulation and deencapsulation 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
The first statement is true because routers decrement the Time to Live (TTL) field in the IP header of a packet by one to ensure that the packet does not loop indefinitely in the network.
The second statement is false because routers do not change the source IP address of a packet. The source IP remains the same throughout the routing process.
The third statement is true because routers maintain the same source and destination IP addresses. They only modify other fields in the IP header, such as the TTL field.
The fourth statement is true because routers change the source physical address (MAC address) to the physical address of the exit interface. This is necessary for the packet to be correctly delivered to the next hop.
The fifth statement is false because routers do not change the destination IP address of a packet. The destination IP remains the same throughout the routing process.Rate this question:

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 0Explanation
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. The network command is used in OSPF configuration to specify which networks should be advertised by the router. In this case, the 0.0.31.255 wildcard mask is used to include all addresses within the 172.16.0.0/19 network.Rate this question:

Refer to the exhibit. Which path will traffic from the 172.16.1.0/24 network take to get to the 10.0.0.0/24 network?
- A.
ADC
- B.
ABC
- C.
It will load balance the traffic between ADC and ABC
- D.
It will send the traffic via ABC, and will use ADC as a backup path only when ABC fails.
Correct Answer
C. It will load balance the traffic between ADC and ABCExplanation
The given exhibit does not provide any information about the network topology or the routing protocols being used. Therefore, it is not possible to determine the exact path that traffic from the 172.16.1.0/24 network will take to reach the 10.0.0.0/24 network. However, the answer states that the traffic will be load balanced between ADC and ABC, which means that the traffic will be distributed between these two paths.Rate this question:

Ip route 172.16.0.0 255.255.0.0 192.168.0.1
- D.
Ip route 172.16.0.0 255.255.0.0 192.168.0.2
- E.
Ip route 192.168.0.1 172.16.0.0 255.255.0.0 S0/0
Correct Answer(s)
A. Ip route 172.16.0.0 255.255.0.0 S0/0
D. Ip route 172.16.0.0 255.255.0.0 192.168.0.2Explanation
The network administrator can configure two static routes on Router1 to enable Host A to reach network 172.16.0.0. The first static route is "ip route 172.16.0.0 255.255.0.0 S0/0", which specifies that any traffic destined for the 172.16.0.0 network should be sent out of the S0/0 interface. The second static route is "ip route 172.16.0.0 255.255.0.0 192.168.0.2", which specifies that any traffic destined for the 172.16.0.0 network should be forwarded to the next-hop IP address 192.168.0.2. These two static routes will allow Router1 to properly route traffic to the 172.16.0.0 network.Rate this question:

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 first agree on the network type. This is important because OSPF supports different network types such as broadcast, point-to-point, and non-broadcast multi-access networks, and the routers need to be configured with the same network type to establish adjacency. Additionally, the routers must use the same dead interval, which is the time period that OSPF waits before declaring a neighbor as dead. This ensures that both routers have the same timing for detecting and responding to neighbor failures.Rate this question:
