All mapped multicast MAC addresses begin with 0x0100.5E

The router performs the mapping before it hands the packet off to a switch

All multicast MAC addresses end with 0x0100.5E

The mapping process may generate overlapping addresses, which can cause receivers to receive unwanted packets

All destination MAC addresses begin with an octet of binary 1s

14. Refer to the exhibit.

An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3.

Which mechanism should the engineer apply in order to steer the traffic correctly?

The MED attribute can be applied on R2 to influence R1 to use it as the primary path.

The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.

The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.

The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.

15. Refer to the exhibit.

How are packets directed through the data plane when SRv6 is implemented?

An ordered list of segments is encoded in a routing extension header

16. Which two statements about route reflectors are true? (Choose two.)

Routes received from nonclient peers are reflected to route reflector cluster as well as OSPF peers.

Routes received from a route reflector client is reflected to other clients and nonclient peers.

If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.
