A network administrator is deploying 10 IP cameras, each requiring 15W of PoE. The switch has a PoE budget of 120W. The administrator connects 8 cameras successfully, but the 9th and 10th cameras do not power on. What is the most likely reason?

The cameras are not on the same VLAN.

The PoE budget is exhausted; 8 cameras use 120W, leaving no power for the remaining cameras.

The switch ports are configured as trunk ports.

What problem does the Spanning Tree Protocol (STP) prevent in a switched network?

Packet loss due to network congestion

Unauthorized access to the network

IP address conflicts between devices

Broadcast storms caused by Layer 2 loops

What is the purpose of Simple Network Management Protocol (SNMP) in switch management?

To provide a graphical user interface for configuration

To monitor and collect statistics from network devices

To route packets between different networks

What is the primary function of a Layer 2 switch?

Translate private IP addresses to public IP addresses

Forward frames based on destination MAC addresses

Filter traffic based on application-layer protocols

Route packets between different IP subnets

Which feature is typically used on a Layer 3 switch to enable routing between VLANs?

Switch virtual interfaces (SVIs)
