#1. Which of the following is a layer 2 protocol used to maintain a loop-free network?

VTP

STP

RIP

CDP

#2. You have 10 hosts plus a server connected to a switch. Each device is running 10Mbps halfduplex. What is the bandwidth available for each device when it communicates to the server?

1Mpbs

2Mbps

10Mbps

100Mbps

#3. What is the result of segmenting a network with a bridge (switch)? (Choose two options.)

Select all that apply:

It increases the number of collision domains.

It decreases the number of collision domains.

It increases the number of broadcast domains.

It makes smaller collision domains.

#4. What will occur if two Cisco LAN switches are connected with a single crossover cable?

The switch port link lights will be off on both switches, indicating that the ports are not connected.

The switch port link light will be off on one switch, indicating that STP has disabled the port.

The switch port link lights will flash amber, indicating an error.

The switch port link lights will be green, indicating normal operation.

#5. You want to ensure that only the server can connect to port fa0/1 on your Catalyst switch. What can you do to ensure that only the MAC address of the server is allowed by switch port fa0/1? (Choose two.)

Select all that apply:

Configure port fa0/1 to accept connections only from the static IP address of the server.

Employ a proprietary connector type on fa0/1 that is incompatible with other host connectors.

Configure the MAC address of the server as a static entry associated with port fa0/1.

Configure port security on fa0/1 to reject traffic with a source MAC address other than that of the server.

#6. Which statement describes a spanning-tree network that has converged?

All switch and bridge ports are in the forwarding state.

All switch and bridge ports are assigned as either root or designated ports.

All switch and bridge ports are in either the forwarding or blocking state.

All switch and bridge ports are either blocking or looping.

#7. Your network design emphasizes efficient, error-free transport instead of fast transport. Which switching mode should be configured on the new switches to provide error-free transport to the network?

Cut-through

FragmentFree

Store-and-forward

FastForward

#8. What are the three distinct functions of layer 2 switching that increase available bandwidth on the network? (Choose three.)

Select all that apply:

Address learning

Routing

Forwarding and filtering

Creating network loops

Loop avoidance

IP addressing

#9. You are working on a network design and determine that a new testing application requires multiple hosts that must be capable of sharing data between each host and server running 10Mbps. Other departments use applications that require less than 3Mbps to the server. What should you recommend?

Replace the 10Mbps Ethernet hub with a 100Mbps Ethernet hub.

Install a router between departments.

Use a switch with a 100Mbps uplink to the server and 10Mbps to the hosts.

Use a bridge to break up collision domains.

#10. What technology is used by Catalyst switches to resolve topology loops and ensure that data flows properly through a single network path?

RIP

STP

IGRP

Store-and-forward
