   What is the primary role of a bridge domain in a Layer 2 network?

   • ATo isolate broadcast and multicast traffic within a defined Layer 2 broadcast domain.
   • BTo assign IP addresses to connected hosts.
   • CTo route traffic between different subnets.
   • DTo provide encryption for Layer 2 frames.

   What is the purpose of MAC address learning in a Layer 2 switch?

   • ATo prevent unauthorized devices from connecting to the network.
   • BTo assign IP addresses to devices based on their MAC addresses.
   • CTo authenticate devices before allowing them to send traffic.
   • DTo build a forwarding database that maps MAC addresses to ports, enabling precise frame forwarding.

   A network has two switches connected by two redundant links, creating a Layer 2 loop. A broadcast frame enters the loop. What is the most immediate consequence of this loop?

   • AThe broadcast frame is continuously replicated and forwarded around the loop, potentially causing a broadcast storm.
   • BThe switches will automatically load-balance the traffic across the two links.
   • CThe switches will learn the source MAC address and forward the frame only on one link.
   • DThe switches will drop the broadcast frame to prevent the loop.

   What is the effect of mapping multiple VLANs to the same bridge domain?

   • AIt requires a router to forward traffic between the VLANs.
   • BIt creates separate broadcast domains for each VLAN.
   • CIt allows the VLANs to communicate at Layer 2 without routing.
   • DIt prevents any Layer 2 communication between the VLANs.

   What information is stored in a switch's forwarding database (FDB)?

   • ARouting table entries and next-hop information.
   • BMAC addresses, associated VLANs, and the ports through which they are reachable.
   • CA list of all broadcast domains and their member ports.
   • DIP addresses and their corresponding MAC addresses.
