When comparing and contrasting the similarities and differences between bridges and switches, which of the following are valid statements? Choose all the valid answer choices)
A. Bridges are faster than switches because they have fewer ports.
B. A switch is a multiport bridge,
C. Bridges and switches learn MAC addresses by examining the source MAC address of
each frame received.

TestKing is experiencing network delays. The network administrator discovers that a worker in a location far from the MDF has connected an old 10BASE-T switch with redundant links to the existing network. How could this action be responsible for the impaired network performance?
A. Connecting a host to the old switch has created a broadcast storm.
B. The 10BASE-T switch forced the entire network to be reduced to 10 Mbps operation.
C. The old switch does not support VLANs, which has disabled the VLAN configuration
of the entire the network.
D. The old switch does not support full-duplex operation, effectively forcing half-duplex
operation throughout the network.
E. Spanning Tree Protocol has elected the old switch as the root bridge, creating
inefficient data paths through the switched network.
F. None of the above
Static routing needs to be configured on router TK1. In which situation would the use of a static route be appropriate?

D. To reach a network is more than 15 hops away.
E. To provide access to the Internet for enterprise hosts.
F. None of the above
Router TK1 is not operating as expected and you want to verify that the router booted using the correct IOS image. Which command should be used to determine which IOS is running on the router?

F. None of the above
The network administrator has configured port security on a TestKing switch. Why would a network administrator configure port security on this TestKing device?

D. To prevent the IP and MAC address of the switch and associated ports
E. None of the above

C. A FS is a backup route, stored in the topology table
D. A FS is a primary route, stored in the topology table
E. None of the above

In a switched LAN network, what is the Spanning-Tree algorithm used for?
A. It is used to provide a mechanism for routing updates in switched environments.
B. It is used to prevent routing loops in networks with redundant routes.
C. It is used to prevent switching loops in networks with redundant switched routes.
D. It is used to manage, the addition, deletion, and naming of VLANs across multiple
switches.
E. It is used to segment a network into multiple collision domains.
F. None of the above.
G. All of the above are functions of STP.
