Learn Spanning Tree Protocol mcq questions and answers with easy and logical explanations for various competitive examination, interview and entrance test Page-2 section-1

11
Which of the following is a layer 2 protocol used to maintain a loop-free network?
Discuss
Answer & Solution
Answer: Option B
Solution:
The Spanning Tree Protocol is used to stop switching loops in a switched network with redundant paths.
12
You need to allow one host to be permitted to attach dynamically to each switch interface. Which two commands must you configure on your catalyst switch to meet this policy?
1. Switch (config-if) # ip access-group 10
2. Switch (config-if) # switchport port-security maximum 1
3. Switch (config) # access-list 10 permit ip host 1
4. Switch (config-if) # switchport port-security violation shutdown
5. Switch (config) # mac-address-table secure
Discuss
Answer & Solution
Answer: Option B
Solution:
The switchport port-security is an important command, and it's super easy with the CNA; however, from the CLI, you can set the maximum number of MAC addresses allowed into the port, and then set the penalty if this maximum has been passed.
13
What command will display the forward/filter table?
Discuss
Answer & Solution
Answer: Option C
Solution:
The command show mac address-table displays the forward/filter table on the switch.
14
If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?
Discuss
Answer & Solution
Answer: Option C
Solution:
Since the source MAC address is not in the MAC address table, the switch will add the source address and the port it is connected to into the MAC address table and then forward the frame to the outgoing port.
15
What is the result of segmenting a network with a bridge (switch)?
1. It increases the number of collision domains.
2. It decreases the number of collision domains.
3. It increases the number of broadcast domains.
4. It decreases the number of broadcast domains.
5. It makes smaller collision domains.
6. It makes larger collision domains.
Discuss
Answer & Solution
Answer: Option A
Solution:
Bridges break up collision domains, which would increase the number of collision domains in a network and also make smaller collision domains.
16
