A financial trading firm is deploying a new market data distribution system. The system uses multicast to distribute data to a large number of receivers. The network team must ensure that multicast traffic is forwarded only to receivers that have explicitly requested it, and that the forwarding path is optimized for low latency. Which multicast model and protocol combination should be used?

A network engineer is troubleshooting a performance issue in a data center VLAN. The engineer suspects that excessive broadcast traffic is consuming bandwidth. Which tool or feature can be used to limit the impact of broadcast traffic on the network?

VLAN access control lists (VACLs)

A storage admin reports that a backup job between two servers in the same leaf-spine fabric is performing poorly. The source server is connected to leaf-1, and the destination server is connected to leaf-3. The fabric uses VXLAN with EVPN control plane. While tracing the packet flow, you notice the source and destination are in the same VNI but on different VTEPs. Which forwarding path will the unicast frame take from the source server to the destination server?

Leaf-1 encapsulates the frame in a VXLAN header with the destination VTEP IP (leaf-3) and forwards it via the spine to leaf-3, which decapsulates and delivers it to the destination server.

Leaf-1 forwards the frame to the destination MAC directly via the spine, which then forwards it to leaf-3.

Leaf-1 floods the frame to all VTEPs in the VNI, including leaf-3, because the destination MAC is not in the local MAC table.

The spine receives the frame, looks up the destination MAC in its VNI table, and forwards it directly to leaf-3.

A server connected to port 10 on a Nexus 9000 switch sends an Address Resolution Protocol (ARP) request for the default gateway. The switch has the destination IP in its FIB but not the destination MAC in its MAC address table. How will the switch handle this frame?

The switch will drop the frame because the destination MAC is unknown.

The switch will flood the frame out all ports in the same VLAN, except the port it was received on.

The switch will route the frame to the gateway based on the destination IP in the FIB.

The switch will send the frame to the CPU to be processed and forwarded to the gateway.
