Question 7 of 116

What are three reasons that switches supersede bridges? (Choose three.)

Smaller frame buffers decrease latency.

Forward, filter, or flood frames.

Multiple simultaneous communications between ports.

Correct Answer: B, C, E

Question 8 of 116

What action does a switch take if the destination MAC address is unknown?

Discard frame

Send ICMP unreachable message to source

Flood packet on all ports

Compare destination IP address against an ACL to determine if it is permitted

Send gratuitous ARP on all ports and wait for reply before forwarding

Correct Answer: C

When a switch receives a frame with an unknown destination MAC address, it floods the frame out of all ports except the one on which it was received. This process ensures that the frame has a chance to reach its intended recipient, which may then respond and allow the switch to learn the MAC address, updating its MAC address table accordingly.

Question 9 of 116

Which statement describes the purpose of the MAC address forwarding table of a switch?

The switch consults the forwarding table to determine the best route to a destination.

The switch consults the forwarding table to determine the output port.

The switch consults the forwarding table to determine if the packet is routable.

The switch consults the forwarding table to determine if access control permits the packet.

Correct Answer: B

Broadcasts are flooded to all VLANs.

Collisions are flooded to all VLANs.

A Layer 3 device is required to route packets between VLANs.

A Layer 2 device is required to route packets between VLANs.
