1. An IPv6 address is made up of how many bits?

d. 128

An IPv4 protocol defines a 32 bit dotted decimal address which is whereas the IPv6 protocol defines addresses made up of 8 bytes or 128 bits not just 1 byte.

2. The subnet mask of an IP address does which of the following?

b. Defines network and host portions of an IP address.

All 1’s represent the IP address belonging to the network and all 0’s represent the IP address belonging to the host.

4. Which of the following is a private IP address and can’ t be routed across the Internet

b. 172.19.243.254

B falls within the private range of class B in IP addresses.

11. When using TCP/IP, which of the following must computers on the same logical network have in common? (Choose all that apply.)

a. Network ID

b. Subnet mask

Because the computers are on the same logical network, both the network ID and subnet mask must match.

14. How many bits must be reallocated from host ID to network ID to create 16 subnets?

Masking 4 bits of the octet byte would yield a total of 16 subnets using formula 2^n where n equals 4.

15. For the Class C network address 192.168.10.0, which of the following subnet masks

provides 32 subnets?

c. 255.255.255.248.

You gave us the answer in the webinar I viewed.

16. How many host bits are necessary to assign addresses to 62 hosts?

a. 6

2 masked and 6 unmasked using formula 2^n – 2 where n equals

20. Which of the following is a reason to subnet? (Choose all that apply.)

a. Networks can be divided into logical groups.

c. Subnetting can decrease the size of broadcast domains.

Sub netting makes efficient use IP addresses and improves . The use of subnet’s can also help reduce network traffic by having routers that represent whole subnets instead of a router per computer.
