The output of the Router# show interfaces serial 0/1 command displays the following:Serial0/1 is up, line protocol is down.What is the most likely cause for the line protocol being down?
- A.
Serial0/1 is shutdown.
- B.
There is no cable connecting the routers.
- C.
The remote router is using serial 0/0.
- D.
No clock rate has been set.
Correct Answer
D. No clock rate has been set.Explanation
The most likely cause for the line protocol being down is that no clock rate has been set. The line protocol being down indicates that there is a physical layer issue with the serial interface. In this case, it suggests that the clock rate, which is responsible for synchronizing the transmission between the routers, has not been configured on the interface. Without a clock rate, the interface cannot establish a proper connection with the remote router, resulting in the line protocol being down.Rate this question:

- B.
Ip route 172.16.0.0 255.255.0.0 192.168.0.1
- C.
Ip route 172.16.0.0 255.255.0.0 S0/0/1
- D.
Ip route 172.16.0.0 255.255.0.0 S0/0/0
Correct Answer
D. Ip route 172.16.0.0 255.255.0.0 S0/0/0Explanation
The correct answer is "ip route 172.16.0.0 255.255.0.0 S0/0/0". This is the correct static route configuration that should be added to Router1 in order for host A to reach host B on the 172.16.0.0 network. The "ip route" command is used to configure static routes, and in this case, it specifies the destination network 172.16.0.0 with a subnet mask of 255.255.0.0. The next-hop interface for this route is S0/0/0, indicating that the traffic should be sent out through that interface.Rate this question:

- A.
172.16.0.0/21
- B.
172.16.1.0/22
- C.
172.16.0.0 255.255.255.248
- D.
172.16.0.0 255.255.252.0
Correct Answer
A. 172.16.0.0/21Explanation
The given networks range from 172.16.0.0/24 to 172.16.7.0/24. To summarize these networks, we need to find a network address that can include all the addresses within this range. The /21 subnet mask allows for a range of 8 subnets, each with 2048 addresses. This is sufficient to cover the range from 172.16.0.0/24 to 172.16.7.0/24. Therefore, the correct answer is 172.16.0.0/21.Rate this question:

Which of the following is true regarding CDP and the graphic shown?
- A.
CDP running on Router D will gather information about routers A, B, C, and E.
- B.
By default, Router A will receive CDP advertisements from routers B and C.
- C.
If routers D and E are running different routing protocols, they will not exchange CDP information.
- D.
Router E can use CDP to identify the IOS running on Router B.
Correct Answer
B. By default, Router A will receive CDP advertisements from routers B and C.Explanation
CDP (Cisco Discovery Protocol) is a Cisco proprietary protocol used to gather information about directly connected Cisco devices. The graphic shown indicates that Router A is directly connected to routers B and C. By default, CDP advertisements are sent by routers to their directly connected neighbors. Therefore, Router A will receive CDP advertisements from routers B and C. This allows Router A to gather information about these neighboring routers.Rate this question:

Refer to the exhibit. Given the output in the exhibit, how would a clock rate be determined for this link?
- A.
The rate would be negotiated by both routers.
- B.
A rate would not be selected due to the DCE/DTE connection mismatch.
- C.
The rate configured on the DTE determines the clock rate.
- D.
The rate configured on the DCE determines the clock rate.
Correct Answer
D. The rate configured on the DCE determines the clock rate.Explanation
In this scenario, the rate configured on the DCE (Data Communications Equipment) determines the clock rate. The DCE is responsible for providing clocking to the DTE (Data Terminal Equipment) device. The DTE device relies on the clock signal provided by the DCE. Therefore, the clock rate is determined by the rate configured on the DCE.Rate this question:

A static route that points to the next hop IP will have what administrative distance and metric in the routingtable?
- A.
Administrative distance of 0 and metric of 0
- B.
Administrative distance of 0 and metric of 1
- C.
Administrative distance of 1 and metric of 0
- D.
Administrative distance of 1 and metric of 1
Correct Answer
C. Administrative distance of 1 and metric of 0Explanation
A static route with an administrative distance of 1 and a metric of 0 means that it is a manually configured route with a higher priority than other routes in the routing table. The administrative distance of 1 indicates that it is more reliable and preferred over other routes with higher administrative distances. The metric of 0 suggests that there is no cost associated with this route, making it the most efficient and preferred option for routing traffic.Rate this question:

10.What happens to a static route entry in a routing table when the outgoing interface is not available
- A.
The route is removed from the table
- B.
The router polls neighbors for a replacement route.
- C.
The route remains in the table because it was defined as static.
- D.
The router redirects the static route to compensate for the loss of the next hop device.
Correct Answer
A. The route is removed from the tableExplanation
When the outgoing interface is not available, the router is unable to forward traffic through that interface. As a result, the static route entry associated with that interface becomes invalid and is removed from the routing table. This ensures that the router does not continue to use an invalid route for forwarding packets.Rate this question:

17Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is anEthernet network?
- A.
Adding the next-hop address eliminates the need for the router to do any lookups in the routing table before forwarding a packet.
- B.
In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address.
- C.
Using a next-hop address in a static route provides a route with a lower metric.
- D.
In multi-access networks, using a next-hop address in a static route makes that route a candidate default route.
Correct Answer
B. In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address. -

Correct Answer(s)
A. It starts up automatically and allows the device to detect directly connected neighbor devices that use CDP.
D. It allows systems to learn about each other even if different network layer protocols are configured.Explanation
CDP (Cisco Discovery Protocol) is a Cisco proprietary protocol that operates at the data link layer. It starts up automatically on Cisco devices and allows them to detect directly connected neighbor devices that also use CDP. It facilitates the exchange of information between these devices, allowing them to learn about each other's capabilities and network addresses. Additionally, CDP allows systems to learn about each other even if different network layer protocols are configured, making it compatible with various network setups. However, CDP does not create a topology map of the entire network or forward advertisements about routes for faster convergence.Rate this question:

Correct Answer
A. WinterPark(config)# ip route 0.0.0.0 0.0.0.0 192.168.146.1 Altamonte(config)# ip route 10.0.234.0 255.255.255.0 192.168.146.2 Altamonte(config)# ip route 0.0.0.0 0.0.0.0 s0/1Explanation
The WinterPark router is configured with a default route using the command "ip route 0.0.0.0 0.0.0.0 192.168.146.1", which means that any traffic not matching a specific route will be sent to the next-hop IP address of 192.168.146.1. The Altamonte router is configured with a specific route for the LAN network 10.0.234.0/24 using the command "ip route 10.0.234.0 255.255.255.0 192.168.146.2", which means that any traffic destined for that network will be sent to the next-hop IP address of 192.168.146.2. Additionally, the Altamonte router is also configured with a default route using the command "ip route 0.0.0.0 0.0.0.0 s0/1", which means that any traffic not matching a specific route will be sent out of the serial interface s0/1. This configuration allows both routers to deliver packets from their respective LANs and direct all other traffic to the Internet.Rate this question:

- C.
It indicates that there are 8 subnets in the destination network to which the router can forward packets.
- D.
It indicates the number of consecutive bits, from the left, in the destination IP address of a packet that must match 10.0.0.0 to use that route.
Correct Answer
D. It indicates the number of consecutive bits, from the left, in the destination IP address of a packet that must match 10.0.0.0 to use that route.Explanation
The /8 in the route to the 10.0.0.0 network indicates the number of consecutive bits, from the left, in the destination IP address of a packet that must match 10.0.0.0 to use that route. This is known as the subnet mask or prefix length, and it determines the range of IP addresses that are considered part of the network. In this case, the /8 indicates that the first 8 bits (or the first octet) of the destination IP address must match 10.0.0.0 for the route to be used.Rate this question:
