Answer 6

Classful

Question 7

Answer 7

1- class A
2- class B
3-Class C

Answer 8

False

Question 9

A network design engineer has been asked to design the IP addressing scheme for a customer network. The network will use IP addresses from the 192.168.30.0/24 network. The engineer allocates 254 IP addresses for the hosts on the network but excludes 192.168.30.0/24 and 192.168.30.255/24 IP addresses. Why must the engineer exclude these two IP addresses?

Answer 9

192.168.30.0/24 is the network IP and 192.168.30.255/24 is the IP broadcast address.

Question 12

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

Answer 12

to identify the network address of the destination network

Question 13

What are three characteristics of a multicast transmission? (Choose three.)

Answer 13

1- Router will not forward multicast address in the range of 224.0.0.0 to 224.0.0.255

2- A single packet can be sent to a group of hosts

3- Multicast transmission can be used by router to exchange routing information

Question 14

When IPv4 is configured for a computer on a network, what does the subnet mask identify?

Answer 14
