- Question
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?
- Correct Answer
- It will use the gateway interface MAC at L2 and the actual destination IP at L3
- 1. 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

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: 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: 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.
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.
