Look at the following exhibit carefully; there is no route to 10.1.4.0/24 in the local routing table.
According to the output of R1 in the exhibit, can you tell me why 10.1.4.0/24 is not in R1’s routing
table?

While troubleshooting a network, you need to verify the liveness of hosts in the subnet
192.168.1.64/26. All of the hosts are able to reply to ping requests. How would you confirm the
existing nodes using one single command?

Two routers are connected by a serial link, and are configured to run EIGRP on all interfaces. You
examine the EIGRP neighbor table on both routers (using the show ip eigrp neighbor command)
and see that the router connected over the serial link is listed as a neighbor for a certain amount of
time, but is periodically removed from the neighbor table.
None of the routes from the neighbor ever seem to be learned, and the neighbor transmission
statistics (SRTT, RTO, and Q Count) seem to indicate that no packets are being transmitted
between the neighbors. Which would most likely cause this problem?

Study the exhibit carefully. Two directly connected routers are configured with OSPF. The output
presented in the exhibit can be seen on the console of one router. What most likely cause this
problem?

Refer to the exhibit.

You get reports that Windows users cannot log in anymore when the main MPLS link is down. The
message that users receive is, “There are currently no login servers available to service the login
request.” However, if you modify the MTU of the client machine to 1294, the user can log in. What
would be a reliable fix for this issue?

Refer to the exhibit. You would like to guarantee 7 Mb/s for FTP traffic in your LAN, as it seems
that peer-to-peer traffic is taking up a large amount of bandwidth. When testing the configuration,
you notice that FTP traffic doesnl reach 7 Mb/ s. What is the problem?

Refer to the exhibit. This exhibit shows the NAT configuration for Router A and the output for a
ping issued from device 171.68.200.48 and destined to 172.16.47.142. Based on this information,
what change must be made to Router A in order for the ping to work?

Refer to the exhibit.

Users that are connected to switch SWD are complaining about slow performance when they are
doing large file transfers from a server connected to switch SWB. All switches are running PVST+.
Which option will improve the performance of the file transfers?

Refer to the exhibit.

Clients in VLAN 10 complain that they cannot access network resources and the Internet. When
you try to ping the default gateway from one of the affected clients, you get ping timeouts. What is
the most likely cause of this issue?

Refer to the exhibit.

An OSPF virtual link is configured between R4 and R3. Based upon the show command output,
why is the virtual-link down?
