   A small office has a legacy 2-port bridge connecting two network segments. The bridge is replaced with a 24-port switch. Both devices operate at Layer 2. What is the primary functional advantage the switch provides over the old bridge?

   • AThe switch prevents broadcast storms by default, while a bridge floods broadcasts to all ports.
   • BThe switch can route between VLANs without any additional configuration, while a bridge cannot route at all.
   • CThe switch eliminates the need for MAC address learning because it has a larger forwarding table.
   • DThe switch can forward multiple frames simultaneously between different port pairs, while the bridge forwards one frame at a time.

   What is the primary function of the forwarding database in a Layer 2 switch?

   • ATo authenticate devices before forwarding their frames.
   • BTo enable the switch to forward frames only to the port where the destination MAC address is located.
   • CTo store IP routing information for Layer 3 forwarding.
   • DTo track the number of frames sent and received for billing purposes.

   What happens to an unknown unicast frame (a frame whose destination MAC is not in the forwarding table) in a bridge domain?

   • AThe switch floods the frame out all ports in the bridge domain except the receiving port.
   • BThe switch sends the frame only to the port where the source MAC was learned.
   • CThe switch sends the frame to the router for a route lookup.
   • DThe switch drops the frame because the destination is unknown.

   A network administrator is implementing STP on a network with redundant links. What is the primary function of STP in this environment?

   • ATo load-balance traffic across all redundant links.
   • BTo block redundant paths, creating a loop-free logical topology while maintaining redundancy.
   • CTo increase the speed of the forwarding database.
   • DTo allow all redundant links to forward traffic simultaneously.

   A network engineer is configuring a Juniper switch to isolate broadcast traffic between two departments. Each department must have its own broadcast domain, but both must be able to communicate through a router. What is the correct configuration approach?

   • ACreate a single bridge domain and use access ports to separate the departments.
   • BCreate two VLANs but assign them to the same bridge domain to simplify configuration.
   • CCreate two bridge domains and connect them with a trunk port to allow broadcast traffic to pass between them.
   • DCreate two separate bridge domains, assign each department's ports to a different bridge domain, and configure inter-VLAN routing on the router.
