Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized Which design solution solves this issue?

• A.Apply a more granular load-balancing method on SW2.
• B.Filter IGMP joins on an over -utilized link.
• C.Aggregate links Layer 2 link aggregation.
• D.Apply a more granular load- balancing method on SW1.
• E.Add more links between core switches.

• B.Use two phantom RP addresses
• C.Manipulate the administration distance of the unicast routes to the two RPs
• D.Advertise the two RP addresses in the routing protocol
• E.Manipulate the multicast routing table by creating static mroutes to the two RPs
