QUESTION 13

Which three statements accurately describe Layer 2 Ethernet switches? (Choose three)

A. Microsegmentation decreases the number of collisions on the network.

B. If a switch receives a frame for an unknown destination, it uses ARP to resolve the address.

C. Spanning Tree Protocol allows switches to automatically share VLAN information.

D. In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All

other switches in that broadcast domain will have only one root port.

E. Establishing VLANs increases the number of broadcast domains.

F. Switches that are configured with VLANs make forwarding decisions based on both layer 2 and layer 3 address information.

Correct Answer: ADE

Section: Switching

Explanation

Explanation/Reference:

Switches have a collision domain (a segment) on each port. This microsegmentation greatly reduces the number of devices per segment and decreases collisions

(A). Switches only operate at Layer 2, so ARP is not used (rules out both B and F). Spanning Tree has nothing to do with VLANs. Each VLAN is a separate

broadcast domain, so establishing VLANs adds more broadcast domains (E).
