- Question
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
- Correct Answer
- In the routing table and the topology table
ExplanationSuccessor 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.
- 1. 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
- 2. 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
- 3. 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 Discuss
- 4. With which network type will OSPF establish router adjacencies but not perform the DR/BDR election process?
Options- A. Point-to-Point
- B. Backbone area 0
- C. Broadcast multi-access
- D. Non-broadcast multi-access Discuss
- 5. What is the administrative distance of OSPF?
Options- A. 90
- B. 100
- C. 110
- D. 120 Discuss
- 6. When is redistribution required for EIGRP? Discuss
- 7. 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
- 8. Your switch has a port status LED that is alternating between green and amber. What could this indicate?
Options- A. The port is experiencing errors
- B. The port is shut down
- C. The port is in STP blocking mode
- D. Nothing, this is normal. Discuss
- 9. If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?
Options- A. Discard it and send an error message back to the originating host
- B. Flood the network with the frame
- C. Add the source addres and port to the MAC address table and forward the frame out the destination port
- D. Add the destination to the MAC address table and then forward the frame Discuss
- 10. What command will display the forward / filter table?
Options- A. Show mac filter
- B. show run
- C. show mac address-table
- D. show mac filter-table Discuss

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: 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: show ip eigrp neighbors
Explanation:
The 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.
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: 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.
Correct Answer: The port is experiencing errors
Explanation:
When you connect to a switch port, at first the link lights are orange/amber, and then they turn green, indicating normal operation. If the link light is blinking, you have a problem.
Correct Answer: Add the source addres and port to the MAC address table and forward the frame out the destination port
Explanation:
Since the source MAC address is not in the MAC address table, the switch will add the source address and the port it is connected to into the MAC address table and then forward the frame to the outgoing port.
Correct Answer: show mac address-table
Explanation:
The Command show mac address-table displays the forward/filter table on the switch.
