A network administrator is troubleshooting connectivity between two hosts on different subnets. The hosts can ping their default gateway, but cannot ping each other. Which device is most likely misconfigured?

The switch connecting the hosts

The router connecting the subnets

A network administrator is troubleshooting a performance issue on a LAN. The switch's MAC address table is full, and the switch is flooding frames to all ports. What is the most likely impact on the network?

No impact, because the switch can still forward frames correctly

Increased latency and potential packet loss for all devices

The switch will reboot to clear the MAC table

The switch will drop all frames

Which statement correctly compares the roles of routers and switches in a network?

Switches provide routing between VLANs, while routers provide switching within a VLAN.

Routers connect different networks, while switches connect devices within the same network.

Routers and switches both use MAC addresses to forward traffic between different networks.

Routers forward frames based on MAC addresses, while switches forward packets based on IP addresses.

A switch receives a frame with a destination MAC address that is not in its MAC address table. What does the switch do?

It broadcasts the frame to all ports including the receiving port

It sends the frame to the router

It forwards the frame out all ports except the receiving port

What are the two primary functions of a switch?

MAC address learning and frame forwarding

Path selection and packet forwarding

IP address assignment and DNS resolution

Broadcast domain segmentation and routing between VLANs
