Question 1. What is the purpose of Spanning Tree Protocol in a switched LAN?

To provide a mechanism for network monitoring in switched environments
To prevent routing loops in networks with redundant paths
To prevent switching loops in networks with redundant switched paths
To manage the VLAN database across multiple switches
To create collision domains

Discuss Question

Answer: Option C. -> To prevent switching loops in networks with redundant switched paths

Question 2. 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.

Discuss Question

Answer: Option C. -> All switch and bridge ports are in either the forwarding or blocking state.

Question 3. What does a switch do when a frame is received on an interface and the destination hardware address is unknown or not in the filter table?

Forwards the switch to the first available link
Drops the frame
Floods the network with the frame looking for the device
Sends back a message to the originating station asking for a name resolution

Discuss Question

Answer: Option C. -> Floods the network with the frame looking for the device

Question 4. In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?

During high-traffic periods
After broken links are reestablished
When upper-layer protocols require high reliability
In an improperly implemented redundant topology

Discuss Question

Answer: Option D. -> In an improperly implemented redundant topology

Question 5. If you want to disable STP on a port connected to a server, which command would you use?

disable spanning-tree
spanning-tree off
spanning-tree security
spanning-tree portfast

Discuss Question

Answer: Option D. -> spanning-tree portfast

Question 6. Which of the following statement is true?

A switch creates a single collision domain and a single broadcast domain. A router creates a single collision domain.
A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.
A switch creates a single collision domain and separate broadcast domains. A router provides a separate broadcast domain as well.
A switch creates separate collision domains and separate broadcast domains. A router provides separate collision domains.

Discuss Question

Answer: Option B. -> A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.

Question 7. You have two switches connected together with two crossover cables for redundancy, and STP is disabled. Which of the following will happen between the switches?
