What is a primary benefit of configuring link aggregation (EtherChannel) between two switches?

It reduces the number of MAC addresses in the switch's MAC address table

It provides a dedicated path for management traffic

It eliminates the need for Spanning Tree Protocol

It increases the total bandwidth available between the switches

What is the purpose of 802.1Q tagging in a trunk link?

To prioritize frames based on their quality of service requirements

To identify which VLAN a frame belongs to as it traverses the trunk

To encrypt the frame to prevent unauthorized access

To compress the frame to reduce bandwidth usage

A technician is troubleshooting a connectivity issue. PC-A sends a frame to PC-B, but PC-B does not receive it. The switch's MAC address table shows PC-B's MAC address associated with the correct port. What is the most likely Layer 2 cause?

The switch is flooding the frame out all ports

The port connected to PC-B is in a blocked state

The frame is corrupted and dropped by the switch

PC-A's MAC address is not in the MAC address table

A technician needs to isolate broadcast traffic between two departments on the same switch. Each department should have its own broadcast domain. What should be configured?

Configure the ports as trunk ports

Enable Spanning Tree Protocol on the switch

Configure port security on the switch ports

Create two VLANs and assign each department's ports to the appropriate VLAN

A technician is troubleshooting a network where two switches are connected by two links. Both links are up, but the network is experiencing broadcast storms. STP is enabled on both switches. What is the most likely reason STP is not preventing the loop?

The native VLAN is different on the two switches

Both links are in the same EtherChannel, and STP sees them as one logical link

One switch has STP disabled on the ports connecting to the other switch

The switches are in different VLANs, and STP runs per VLAN
