Question 1

When PVST is running over a switched network, which port state can participate in BPDU frame forwarding based on BPDUs received, but does not forward data frames?

Answer 1

listening

Question 2

Which STP port role is adopted by a switch port if there is no other port with a lower cost to the root bridge?

Answer 2

root port

Question 3

What value determines the root bridge when all switches connected by trunk links have default STP configurations?

Answer 3

MAC address

Question 4

A network administrator configured an EtherChannel link with three interfaces between two switches. What is the result if one of the three interfaces is down?

Answer 4

The remaining two interfaces continue to load balance traffic.

Question 5

Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?

Answer 5

interface range GigabitEthernet 0/4 - 5

Question 6

What is one way to correct a spanning tree failure?

Answer 6

Manually remove redundant links in the switched network.

Question 6

An administrator is troubleshooting a switch and wants to verify if it is a root bridge. What command can be used to do this?

Answer 6

show spanning-tree

Question 7

A network administrator is analyzing the features that are supported by different first-hop router redundancy protocols. Which statement describes a feature that is associated with HSRP?

Answer 7

HSRP uses active and standby routers.

Question 8

After the election of the root bridge has been completed, how will switches find the best paths to the root bridge?

Answer 8

Each switch will analyze the sum of all port costs to reach the root and use the path with the lowest cost.

Question 9

What is an accurate description of redundancy?

Answer 9

designing a network to use multiple paths between switches to ensure there is no single point of failure

Question 10

A network administrator is analyzing the features that are supported by different first-hop router redundancy protocols. Which statement is a feature that is associated with GLBP?

Answer 10

GLBP allows load balancing between routers

Question 11

As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?

Answer 11

grouping multiple physical ports to increase bandwidth between two switches

Question 11

Which mode configuration setting would allow formation of an EtherChannel link between switches SW1 and SW2 without sending negotiation traffic?

Answer 11

SW1: on

SW2: on

Question 11

Which PAgP mode mode places an interface in a passive negotiating state in which the interface responds to the PAgP packets that it receives, but does not initiate PAgP negotiation?

Answer 11

PAgP desirable

Question 12

When a range of ports is being configured for EtherChannel, which mode will configure LACP on a port only if the port receives LACP packets from another device?

Answer 12

passive

Question 13

During the implementation of Spanning Tree Protocol, all switches are rebooted by the network administrator. What is the first step of the spanning-tree election process?

Answer 13

All the switches send out BPDUs advertising themselves as the root bridge.

Question 13

Which PAgP mode forces the interface to channel without PAgP?

Answer 13

On

Question 13

When EtherChannel is implemented, multiple physical interfaces are bundled into which type of logical connection?

Answer 13

port channel

Question 13

Which is the default STP operation mode on Cisco Catalyst switches?

Answer 13

PVST+

Question 14

When EtherChannel is configured, which mode will force an interface into a port channel without exchanging aggregation protocol packets?

Answer 14

on
