QUESTION 180
A medium-sized company has a Class C IP address. It has two Cisco routers and one non-Cisco
router. All three routers are using RIP version 1. The company network is using the block of
198.133.219.0/24. The company has decided it would be a good idea to split the network into
three smaller subnets and create the option of conserving addresses with VLSM. What is the best
course of action if the company wants to have 40 hosts in each of the three subnets?

QUESTION 182
Refer to the exhibit. S0/0 on R1 is configured as a multipoint interface to communicate with R2
and R3 in the hub-and-spoke Frame Relay topology. While testing this configuration, a technician
notes that pings are successfully from hosts on the 172.16.1.0/24 network to hosts on both the
172.16.2.0/25 and 172.16.0.2.128/25 networks. However, pings between hosts on the
