What is the main purpose of a subnet mask in IPv4 addressing?

• To identify the gateway of the network

• To determine the network and host portions of an IP address

• To provide security by masking IP addresses

Why would a Layer 2 switch need an IP address?

• to enable the switch to send broadcast frames to attached PCs

• to enable the switch to function as a default gateway

• to enable the switch to be managed remotely

• to enable the switch to receive frames from attached PCs

How is the privileged EXEC mode access secured on a switch?

• enable class

• Protocol

• Time to live

• Differentiated Service (DS)

• Source IP address

What destination MAC address would be included in a frame sent from a source device to a destination device on a remote local network?

• A broadcast MAC address of FF-FF-FF-FF-FF-FF.

• The MAC address of the destination device.

• The MAC address of the local router interface.
