How does replacing a hub with a switch affect CSMA/CD behavior in an Ethernet network?

The network shown in the exhibit was designed to provide reliability through redundancy. Both of
the IDF switches, S3 and S4, are connected to both of the MDF switches, S1 and S2. Which
configuration scenario will provide a loop-free switching environment?

The RIP network shown in the graphic has been fully operational for two days. Each routing table
is complete. Which networks will be included in the next routing update from the Apples router to
the Pears router?

Refer to the exhibit. In the Frame Relay network, which IP addresses would be assigned to the
interfaces with point-to-point PVCs?

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?

A network administrator needs to allow only one Telnet connection to a router. For anyone viewing
the configuration and issuing the show run command, the password for Telnet access should be
encrypted. Which set of commands will accomplish this task?

Refer to the exhibit. Which address and mask combination represents a summary of the routes
learned by EIGRP?

Refer to the exhibit. The two connected ports on the switch are not turning orange or green. What
would be the most effective steps to troubleshoot this physical layer problem? (Choose three.)

Refer to the exhibit. A network administrator on workstation M uses Telnet to log in to the
command line interface of router A. The administrator wishes to discover information about active
workstations on the LAN attached to router A, including their IP and MAC addresses. Which
command will provide this information?

Refer to the exhibit. Configuration of both switches has been completed. During testing, the
network administrator notices that users on SwitchA can not connect with users in the same VLAN
on SwitchB. What should be done to solve this problem?
