A network administrator is planning a network installation for a large organization. The design
requires 100 separate subnetworks, so the company has acquired a Class B network address.
What subnet mask will provide the 100 subnetworks required, if 500 usable host addresses are
required per subnet?

An administrator must assign static IP addresses to the servers in a network. For network
192.168.20.24/29, the router is assigned the first usable host address while the sales server is
given the last usable host address. Which of the following should be entered into the IP properties
box for the sales server?

The network administrator of the Oregon router adds the following command to the router
configuration: ip route 192.168.12.0 255.255.255.0 172.16.12.1. What are the results of adding
this command? (Choose two.)

Users on the 172.17.22.0 network cannot reach the server located on the 172.31.5.0 network.
The network administrator connected to router Coffee via the console port, issued the show ip
route command, and was able to ping the server.

Based on the output of the show ip route command and the topology shown in the graphic, what is
the cause of the failure?

The network administrator has found the following problem.

The remote networks 172.16.10.0, 172.16.20.0, and 172.16.30.0 are accessed through the
Central router’s serial 0/0 interface.

No users are able to access 172.16.20.0. After reviewing the command output shown in the
graphic, what is the most likely cause of the problem?

Refer to Exhibit:

Based on the network shown in the graphic which option contains both the potential networking
problem and the protocol or setting that should be used to prevent the problem?

What information does a router running a link-state protocol use to build and maintain its
topological database? (Choose two.)
