Add the destination to the MAC address table and then forward the frame

Discard it and send an error message back to the originating host

Add the source address and port to the MAC address table and forward the frame out the destination port

Flood the network with the frame

Which of the following is true when describing an anycast address?

Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.

Packets addressed to a unicast address are delivered to a single interface.

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.

Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?

The updated information will be added to the existing routing table.

The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence.

The update will be ignored and no further action will occur.

The updated information will replace the existing routing table entry.

They will all load-balance.
