Troubleshooting switching

Question 1

You manage a network with a single switch. On each switch port, a hub connects multiple devices to the
switch.
Which condition are you most likely to experience on the network?

Interference

Crosstalk

Echo

Collisions

Attenuation

Answer 1

Collisions

Question 2

A user reports that network access from her workstation is very slow. The problem does not seem to be
affecting any other users.
Which of the following conditions is the most likely cause?

Broadcast storm

Switching loop

Duplex mismatch

Incorrect VLAN

Answer 2

Duplex mismatch

Question 3

You manage a network with multiple switches. You find that your switches are experiencing heavy broadcast
storms.
Which of the following will help reduce the effects of a broadcast storm?

Manually set the speed for each switch port

Disable auto-duplex detection

Enable spanning tree on the switches

Configure each switch with a single trunk port

Answer 3

Enable spanning tree on the switches

Question 4

You manage a local area network with several switches. A new employee has started today so you connect
her workstation to a switch port.
After connecting the workstation, you find that the workstation cannot get an IP address from the DHCP
server. You check the link and status lights and the connection is working properly. A ping to the loopback
address on the workstation succeeds. No other computers seem to have the problem.
Which of the following is the most likely cause of the problem?

Incorrect default gateway setting

Incorrect VLAN assignment

Half-duplex setting on the switch and workstation

Switching loop

Answer 4

Incorrect VLAN assignment

Question 5

Which of the following solutions would you implement to eliminate switching loops?
Auto-duplex
Spanning tree
CSMA/CD
Inter-vlan routing

Answer 5

Spanning tree

Question 6

Select the statement that best describes a broadcast storm.

A broadcast storm occurs when the amount of electrical interference on a cable exceeds acceptable
levels, broadcasting a storm of noise, and preventing accurate data transfer.

A broadcast storm occurs when a network server loses its connection to the network, and the
disconnected cable sends feedback messages that overwhelm the network cable capacity.

A broadcast storm occurs when there are so many broadcast messages on the network that they
approach or exceed the network bandwidth.

A broadcast storm occurs when the level of TCP/IP transfers overwhelm a gateway.

Answer 6

A broadcast storm occurs when there are so many broadcast messages on the network that they
approach or exceed the network bandwidth.
