It sends the frame back to the sender

It stores the frame in a buffer

What is stored in the MAC address table of a switch?

MAC addresses and interface IDs

What happens when a switch learns the MAC address of a device?

It adds the MAC address to its MAC address table

It deletes the MAC address from its MAC address table

It forwards the frame to all ports

What is the purpose of the MAC address table in a Layer 2 switch?

To store MAC addresses of connected devices

To store IP addresses of connected devices

To store the routing paths of data packets

To store the DNS names of connected devices

What is the forwarding and filtering decision in a Layer 2 switch?

Deciding which port to forward the frame to

Deciding which IP address to forward the frame to

Deciding which MAC address to forward the frame to

Deciding which DNS name to forward the frame to

What is a broadcast storm?

When a network is overwhelmed by broadcast traffic

When a network is overwhelmed by unicast traffic

When a network is overwhelmed by multicast traffic

When a network is overwhelmed by anycast traffic

What is the main function of loop avoidance in a switch?

To prevent the creation of multiple paths to a destination device

To prevent the switch from overheating

To prevent the switch from forwarding frames

To prevent the switch from storing MAC addresses

What happens if loop avoidance schemes are not implemented in a network?

The switches will flood (broadcast) endlessly throughout the internetwork.

The network will operate normally.

The network will shut down immediately.

The routers will stop functioning.

What is the result of a switch receiving multiple frames from multiple segments simultaneously?

The MAC address filter table becomes confused.

The switch will operate faster.

Store-and-Forward and Adaptive switching

Cut-Through and Adaptive switching

Store-and-Forward and Full-Duplex switching

What does a late collision indicate in a network?

A host attempted to transmit after another host transmitted at least the first 64 bytes of its frame

A host attempted to transmit before another host transmitted the first 64 bytes of its frame

A host attempted to transmit after another host transmitted the first 128 bytes of its frame

A host attempted to transmit before another host transmitted the first 128 bytes of its frame

What is one of the causes of late collisions in an Ethernet LAN?

The LAN having too many switches
