1 What two advantages does CIDR provide to a network? (Choose two.)
reduced routing table size
d ynamic address assignment automatic route redistribution
reduced routing update traffic
a utomatic summarization at classful boundaries

Refer to the exhibit. A network engineer is summarizing the two groups of routes on router R1the exhibit. Which summarization will work for all the subnets?
192.168.0.0/23
192.168.0.0/22
192.168.0.0/21
1 92.168.0.0/20
4 Which of the following are contained in the routing updates of classless routing protocols? (Ctwo.)
32-bit address
n ext hop router interface subnet mask
u nicast host address Layer 2 address
5 Which of the following problems does VLSM help to alleviate?
the shortage of IP addresses
the difficulty of assigning static IP addresses to hosts in large enterprises
the complexity of implementing advanced routing protocols such as OSPF and EIGRP
t he shortage of network administrators qualified in the use of RIP v1 and IGRP
6 What does VLSM allow a network administrator to do?
utilize one subnet mask throughout an autonomous system
u tilize 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

10 A network administrator is tasked with dividing up a class C network among the QA, Sales, aAdministration departments. The QA department is made up of 10 people, the Sales is madepeople, and the Administration has 6. Which two subnets masks adequately address the QAdepartments? (Choose two.)
2 55.255.255.252 for QA 255.255.255.224 for Sales
2 55.255.255.240 for QA 255.255.255.248 for QA
255.255.255.0 for Sales
