C

How does the network layer use the MTU value? A. The network layer depends on the higher level layers to determine the MTU. B. The network layer depends on the data link layer to set the MTU, and adjusts the speed of transmission to accommodate it. C. The MTU is passed to the network layer by the data link layer D. To increase speed of delivery, the network layer ignores the MTU.

C

Within a production network, what is the purpose of configuring a switch with a default gateway address? A. Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination. B. A switch must have a default gateway to be accessible by Telnet and SSH. C. The default gateway address is used to forward packets originating from the switch to remote networks.* D. It provides a next-hop address for all traffic that flows through the switch.
