Options- A. Issue the show ip route command on the router connected to the switch
- B. Issue the show cdp neighbor command on the router connected to the switch
- C. Issue the show ip arp command on the router connected to the switch
- D. Issue the show cdp neighbors detail command on the router connected to the switch Discuss
- 5. You are troubleshooting a connectivity problem in your corporate network and want to isolate the problem. You suspect that a router on the route to an unreachable network is at fault. What IOS user exec command should you issue?
Options- A. Router>ping

Options- A. Hop count
- B. MTU
- C. Cumulative interface delay
- D. Load Discuss

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
- 8. 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
- 9. 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?

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: Issue the show cdp neighbors detail command on the router connected to the switch
Explanation:
Although option A is certainly the "best" answer, unfortunately option E will work just fine and your boss would probably prefer you to use the show cdp neighbors detail command.
Correct Answer: Router>trace
Explanation:
The command traceroute (trace for short), which can be issued from user mode or privileged mode, is used to find the path a packet takes through an internetwork and will also show you where the packet stops because of an error on a router.
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: 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: 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.
