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

Question 13. What command will display the forward/filter table?

show mac filter
show run
show mac address-table
show mac filter-table

Discuss Question

Answer: Option C. -> show mac address-table

Question 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?

Discard it and send an error message back to the originating host
Flood the network with the frame
Add the source address and port to the MAC address table and forward the frame out the destination port
Add the destination to the MAC address table and then forward the frame

Discuss Question

Answer: Option C. -> Add the source address and port to the MAC address table and forward the frame out the destination port

Question 15. What is the result of segmenting a network with a bridge (switch)?

Question 17. 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

Discuss Question

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

Question 18. 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 19. 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 20. Which of the following statement is true?

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.
