b) 64 bit
c) 16 bit
d) 32 bit
View Answer

2. Version 6 of IP address has how many bits.
a) 64 bits
b) 128 bits
c) 32 bits
d) 256 bits
View Answer

Answer: b
Explanation: Because of the growth of the Internet and the depletion of available IPV4 address, a new version of IP(IPV6), using 128 bits for the IP address, was developed in 1995, and standardized as RFC 2460 in 1998. IPV6 deployment has been ongoing since the mid-2000s.

7. VLSM stands for ________
a) Version Length Subnet Masking
b) Variable Length Subnet Masking
c) Variable Length Surface Masking
d) Version Length Surface Masking
View Answer

Answer: b
Explanation: Variable Length Subnet Mask (VLSM) is a subnet (a segmented piece of a larger network) design strategy where all subnet masks can have varying sizes. This process of “subnetting subnets” enables network engineers to use multiple masks for different subnets of a single class A, B or C network.

8. Many desktops and operating systems include which protocol?
a) IPv6 protocol
b) IPv4 protocol
c) Both IPv6 and IPv4 protocol
d) IPv3 protocol

9. The design of the Internet protocol suites adhere to the ________ principle.
a) Data corruption
b) Connection oriented
c) End to End principle
d) Reliability
View Answer

Answer: c
Explanation: The design of the Internet protocol suite adheres to the end-to-end principle, a concept adapted from the CYCLADES project. Under the end-to-end principle, the network infrastructure is considered inherently unreliable at any signal network element or transmission medium and is dynamic in terms of availability of links and nodes.

10. ___________ adjusts the segment size to be smaller than MTU.
a) Internet Protocol 6
b) User Datagram Protocol
c) Internet Protocol 4
d) Transmission Control Protocol
View Answer

Answer: d
