- Question
You need the IP address of the devices with which the router has established an adjacency. Also, the retransmit interval and the queue counts for the adjacent routers need to be checked. What command will display the required information?
Options- A. show ip eigrp adjacency
- B. show ip eigrp topology
- C. show ip eigrp interfaces
- D. show ip eigrp neighbors
- Correct Answer
- show ip eigrp neighbors
ExplanationThe show ip eigrp neighbors command allows you to check the IP addresses as well as the retransmit interval and queue counts for the neighbors that have established an adjacency.

Options- A. Point-to-Point
- B. Backbone area 0
- C. Broadcast multi-access
- D. Non-broadcast multi-access Discuss
- 2. What is the administrative distance of OSPF?
Options- A. 90
- B. 100
- C. 110
- D. 120 Discuss
- 3. If routers in a single area are configured with the same priority value, what value does a router use for the OSPF Router ID in the absence of a loopback interface?
Options- A. The Lowest IP address of any physical interface
- B. The Highest IP address of any physical interface
- C. The Lowest IP address of any logical interface
- D. The Highest IP address of any logical interface Discuss
- 4. When a PC sends a packet to another PC in a remote network, what destination IP address and MAC address will be in the frame that it sends to its default gateway? Discuss
- 5. Two connected routers are configured only with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?
Options- A. The updated information will be added to the existing routing table
- B. The update will be ignored and no further action will occur
- C. The updated information will replace the existing routing table entry
- D. The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence Discuss
- 6. A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?
Options- A. IGRP
- B. OSPF
- C. RIPv1
- D. EIGRP Discuss
- 7. You get a call from a network administrator who tells you that he typed the following into his router: Router (config) #router ospf 1 Router (config-router) # network 10.0.0.0. 255. 0.0.0 area 0 He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
Options- A. The wildcard mask is incorrect
- B. The OSPF area is wrong
- C. The OSPF Process ID is incorrect.
- D. The AS configuration is wrong Discuss
- 8. Where are EIGRP successor routes stored?
Options- A. In the routing table only
- B. In the neighbor table only
- C. In the routing table and neighbor table
- D. In the routing table and the topology table Discuss
- 9. When is redistribution required for EIGRP? Discuss
- 10. What does a switch do when a frame is received on an interface and the destination hardware address is unknown or not in the filter table?
Options- A. Forwards the switch to the first available link
- B. Drops the frame
- C. Floods the network with the frame looking for the device
- D. Sends back a message to the originating station asking for a name resolution Discuss

Correct Answer: Point-to-Point
Explanation:
No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access network. Frame relay is a non-broadcast multiaccess (NBMA) network by default.
Correct Answer: 110
Explanation:
The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running , by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.
Correct Answer: The Highest IP address of any physical interface
Explanation:
At the moment of OSPF process startup, the highest IP address on any active interface will be the Router ID (RID) of the router . If you have a loopback interface configured (logical interface), then that will override the interface IP address and become the RID of the router automatically.
Correct Answer: It will use the gateway interface MAC at L2 and the actual destination IP at L3
Correct Answer: The update will be ignored and no further action will occur
Explanation:
When a routing update is received by a router, the router first checks the administrative distance (AD) and always chooses the route with the lowest AD. However, if two routes are received and they both have the same AD and differing metrics , then the router will choose the one route with the lowest metrics or , in RIP's case, hop count.
Correct Answer: EIGRP
Explanation:
In this question, we're calling EIGRP just plain old distance vector. EIGRP is an advanced distance-vector routing protocol, sometimes called a hybrid routing protocol because it uses the characteristics of both distance-vector and link-state routing protocols.
Correct Answer: The wildcard mask is incorrect
Explanation:
The administrator typed in the wrong wildcard mask configuration. The wildcard should have been 0.0.0.255 or even 0.255.255.255.
Correct Answer: In the routing table and the topology table
Explanation:
Successor routes are going to be in the routing table since they are the best path to a remote network. However, the topology table has a link to each and every network, so the best answer is topology table and routing table. Any secondary route to a remote network is considered a feasible successor, and those routes are found only in the topology table and used as backup routes in case of primary route failure.
Correct Answer: Redistribution is required when more than one EIGRP session or process is running and they are identified with different ASNs Redistribution shares topology information between EIGRP sessions
Correct Answer: Floods the network with the frame looking for the device
Explanation:
Switches flood all frames that have an unknown destination address. If a device answers the frame, the switch will update the MAC address table to reflect the location of the device.
