In the network shown in the graphic, three bits were borrowed from the host portion
of a Class C address. How many valid host addresses will be unused on the three
point-to-point links combined if VLSM is not used?

protocols? (Choose two.)

Refer to the exhibit. The network administrator wants to create a subnet for the point-
to-point connection between the two routers. Which subnetwork mask would provide
enough addresses for the point-to-point link with the least number of wasted
addresses?

6 What does VLSM allow a network administrator to do?
utilize one subnet mask throughout an autonomous system
• utilize multiple subnet masks in the same IP address space
utilize IGRP as the routing protocol in an entire autonomous system
utilize multiple routing protocols within an autonomous system
7 Which three interior routing protocols support VLSM? (Choose three.)
• OSPF
RIP v1
• RIP v2
• EIGRP
BGP
STP
