- Question
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
- Correct Answer
- The update will be ignored and no further action will occur
ExplanationWhen 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.
- 1. What metric does RIPv2 use to find the best path to a remote network?
Options- A. Hop count
- B. MTU
- C. Cumulative interface delay
- D. Load Discuss
- 2. Which command displays RIP routing updates?
Options- A. Show ip route
- B. debug ip rip
- C. show protocols
- D. Debug ip route Discuss
- 3. Which of the following is the best description of the operation of split horizon?
Options- A. Information about a route should not be sent back in the direction from which the original update came
- B. It splits the traffic when you have a large bus (horizon) physical network
- C. It holds the regular updates from broadcasting to a downed link
- D. It prevents regular update messages from reinstating a route that has gone down Discuss
- 4. What is the command to copy a Cisco IOS to a TFTP server? Discuss
- 5. If you want to have more than one Telnet session open at the same time, what keystroke combination would you use?
Options- A. Tab+spacebar
- B. Ctrl+X, then 6
- C. Ctrl+Shift+X, then 6
- D. Ctrl+Shift+6, then X Discuss
- 6. 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
- 7. 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
- 8. What is the administrative distance of OSPF?
Options- A. 90
- B. 100
- C. 110
- D. 120 Discuss
- 9. 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
- 10. 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

Correct Answer: Hop count
Explanation:
RIPv1 and RIPv2 only use the lowest hop count to determine the best path to a remote network.
Correct Answer: debug ip rip
Explanation:
Debug ip rip is used to show the internet Protocol (IP) Routng Information protocol (RIP) updates being sent and received on the router.
Correct Answer: Information about a route should not be sent back in the direction from which the original update came
Explanation:
A split horizon will not advertise a route back to the same router it learned the route from.
Correct Answer: copy flash tftp
Correct Answer: Ctrl+Shift+6, then X
Explanation:
To keep open one or more Telnet sessions, use the Ctrl+Shift+6 and then X keystroke combination.
Correct Answer: It will use the gateway interface MAC at L2 and the actual destination IP at L3
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: 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: 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: 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.
