• Power over Ethernet

• Port Density

• Forwarding Rate

• Port Number

The layer provides a high-speed backbone link between dispersed networks in a hierarchical network model is called _____________

• application layer

• distribution layer

• access layer

• core layer

Which of the following methods help to prevent the disruption of network services? (Choose two.)

• Changing the routing protocols at regular intervals

• Using redundant connections to provide alternate physical paths

• Installing duplicate equipment to provide failover services

• Removing switches that cause loops

• Using VLANs to segment network traffic

What is a characteristic of out-of-band device management?

• It requires a terminal emulation client.

• It requires Telnet, SSH, or HTTP to access a Cisco device.

• It requires at least one network interface on the device to be connected and operational.

• Out-of-band device management requires a direct connection to a network interface

It is a form of link aggregation used in switched networks

• EtherChannel

• Power Over Ethernet

• OSPF

• Stackable

What is the purpose of the spanning tree algorithm?

• To create a redundant topology.

• To build correct MAC address tables

• To create a loop-free topology

• To find the shortest path to a network address.

• To remove a single point of failure.

How can a broadcast storm be ended?

• Disconnect one of the switches.

• Wait until the frames time out.

• Send an ICMP source quench message.

• Clear the MAC address tables of the switches.

How do switches choose a root bridge?

• They choose the switch with the highest bridge priority

• They choose the switch with the lowest BID

• They choose the switch with the highest BID

• They choose the switch nearest to the default gateway

What states does a port go through from the time when switches first start up to the time when the port is fully operational?

• Blocking, listening, learning, forwarding

• Disabled, listening, learning, forwarding

• Listening, learning, blocking, forwarding

• Blocking, learning, listening, forwarding

• Learning, listening, switching, forwarding

Why might a network administrator change a switch priority to a higher value than that of other switches in the network?

• To make sure that the switch is chosen as the root bridge.

• To make sure that the switch is not chosen as the root bridge.

• To help the network converge more quickly

• To make sure that no ports on the switch are blocked

• To make sure that switch MAC addresses are not used in choosing the root bridge.
