   What is the basic function of Spanning Tree Protocol (STP) in a bridged network?

   • AIt encrypts traffic between switches.
   • BIt increases the speed of MAC address learning.
   • CIt routes traffic between different VLANs.
   • DIt prevents Layer 2 loops by blocking redundant paths while maintaining a single active path between switches.

   A switch receives a frame on a trunk port with an 802.1Q tag indicating VLAN 30. The switch has a bridge domain configured for VLAN 30. What does the switch do with the frame?

   • AStrip the tag and place the frame in the native VLAN.
   • BFlood the frame out of all ports, including access ports in other VLANs.
   • CProcess the frame as part of the bridge domain associated with VLAN 30.
   • DDrop the frame because trunk ports do not accept tagged frames.

   A switch receives a broadcast frame on port ge-0/0/1 in VLAN 20. The switch's FDB contains entries for several hosts in VLAN 20. What will the switch do with the broadcast frame?

   • ADrop the frame because broadcast frames are not forwarded by switches.
   • BForward the frame only to the ports that have FDB entries in VLAN 20.
   • CForward the frame only to the default gateway.
   • DFlood the frame out of all ports in VLAN 20 except ge-0/0/1.

   How does a switch handle broadcast traffic within a bridge domain?

   • AIt drops the frame because broadcast traffic is not allowed.
   • BIt floods the frame out all ports in the bridge domain except the receiving port.
   • CIt forwards the frame only to the port where the destination MAC is learned.
   • DIt sends the frame to the router for processing.

   How do VLANs relate to bridge domains in a Layer 2 network?

   • AEach VLAN maps to a separate bridge domain, isolating Layer 2 traffic between VLANs.
   • BAll VLANs share a single bridge domain to allow inter-VLAN communication.
   • CVLANs are used only for routing, while bridge domains are used for switching.
   • DVLANs are assigned to bridge domains based on IP subnet.
