   A data center network engineer is configuring multicast for a financial trading application that sends real-time market data to a group of 50 servers. The engineer must ensure that multicast traffic is only sent to switches and routers that have active receivers, to conserve bandwidth. Which multicast forwarding model should be implemented?

   • ASource-Specific Multicast (SSM) with PIM-SM and IGMPv3
   • BIGMP snooping only on the access switches
   • CDense Mode multicast with PIM-DM
   • DBidirectional PIM (Bidir-PIM)

   A network architect is designing a new data center network. The applications have the following requirements: 1) A storage replication protocol that requires guaranteed delivery and ordered packets between two specific storage arrays. 2) An IPTV service that streams the same video feed to multiple display devices. 3) A legacy protocol that must be received by all devices on the same VLAN. Which set of traffic types should the architect plan for?

   • A1) Unicast, 2) Multicast, 3) Broadcast
   • B1) Unicast, 2) Broadcast, 3) Multicast
   • C1) Broadcast, 2) Multicast, 3) Unicast
   • D1) Multicast, 2) Unicast, 3) Broadcast

   A network engineer is analyzing the path of a unicast packet from a VM on a Cisco ACI fabric to a VM on a different leaf switch but in the same bridge domain. The destination MAC is known to the source leaf. What is the primary forwarding decision made by the source leaf switch?

   • AIt sends the packet to the gateway MAC address for routing.
   • BIt forwards the packet to the destination leaf switch via the spine based on the destination MAC address.
   • CIt floods the packet to all leaf switches in the fabric.
   • DIt routes the packet based on the destination IP address in its L3 routing table.

   What is a key difference between broadcast and multicast forwarding behavior?

   • ABroadcast is forwarded to all devices in the VLAN, while multicast is forwarded only to devices that have joined the multicast group.
   • BBroadcast is forwarded only to devices that have requested it, while multicast is forwarded to all devices in the VLAN.
   • CBroadcast uses a special destination IP address, while multicast uses a special destination MAC address.
   • DBroadcast is confined to a single subnet, while multicast can cross subnets without any routing protocol.
