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.
