Which two of these functions do routers perform on packets? (Choose two.)

A.
Examine the Layer 2 headers of inbound packets and use that information to determine the
next hops for the packets

B.
Update the Layer 2 headers of outbound packets with the MAC addresses of the next hops

C.
Examine the Layer 3 headers of inbound packets and use that information to determine the
next hops for the packets

D.
Examine the Layer 3 headers of inbound packets and use that information to determine the
complete paths along which the packets will be routed to their ultimate destinations

E.
Update the Layer 3 headers of outbound packets so that the packets are properly directed to
valid next hops

F.
Update the Layer 3 headers of outbound packets so that the packets are properly directed to
their ultimate destinations

Explanation:
This is the basic function of the router to receive incoming packets and then forward them to their
required destination. This is done by reading layer 3 headers of inbound packets and update the
info to layer 2 for further hopping.
