   A network engineer is troubleshooting a connectivity issue. A host sends a broadcast frame, and the switch floods it to all ports in the VLAN. Which type of traffic is this an example of, and what is a common issue associated with it in a large Layer 2 domain?

   • ABroadcast traffic; it can cause a broadcast storm and degrade network performance.
   • BAnycast traffic; it can cause routing loops in the network.
   • CUnicast traffic; it can cause high CPU utilization on the destination server.
   • DMulticast traffic; it can cause unnecessary replication on all switches.

   In a data center leaf-spine network, a host sends a unicast frame to another host on a different leaf switch. Which forwarding decision does the source leaf switch make first?

   • ALook up the destination MAC address in its MAC address table and forward the frame out the port toward the destination leaf switch.
   • BCheck the VLAN ID and drop the frame if the destination is in a different VLAN.
   • CFlood the frame out all ports except the receiving port because the destination MAC address is unknown.
   • DPerform a longest-prefix match on the destination IP address to determine the next-hop IP address.

   An engineer is troubleshooting a unicast flow between two VMs on the same VLAN, but on different leaf switches in a VXLAN EVPN fabric. The engineer checks the MAC address table on the source leaf and sees the destination MAC is present with a next-hop of the destination leaf's VTEP IP. Which action will the source leaf perform on the frame?

   • AIt will forward the frame out the local port where the destination MAC was learned.
   • BIt will encapsulate the frame in a VXLAN header and send it to the destination VTEP IP.
   • CIt will broadcast the frame to all other VTEPs in the VNI.
   • DIt will drop the frame because the destination is not on the local segment.
