What happens when more bits are added to a digital signal arranged in a sequence understood by the sender and receiver?
- A.
A code set is established.
- B.
A word is created.
- C.
An octet is formed.
- D.
Nothing.
Correct Answer
A. A code set is established.Explanation
"The more bits that are added to a digital signal, the greater the number of choices to be made. If the sender and receiver arrange these bits in a preset sequence that is understood, a code set is established." Page 1-1Rate this question:

How many possible symbols can 4 bits represent?
- A.
2.
- B.
4.
- C.
8.
- D.
16.
Correct Answer
D. 16.Explanation
"One bit can indicate only two possible messages. When a second bit is added, the number of possible messages increases to four (22). A further increase to 3 bits increases the possibilities to eight different choices (23). The number of bits (called X) available can have 2 to X possible combinations to represent
information. For example, a code with 8 bits (28) can represent 256 possible messages or symbols. Generally 8 bits of data refers to a unit of data transmission known as a “byte.”" Page 1-2Rate this question:

What is not a recommendation for planning networks using variable length subnet masking (VLSM)?
- A.
Start with the shortest mask.
- B.
Re-address the entire network.
- C.
Aim to use contiguous subnets where possible.
- D.
Choose one or more available subnets and subnet further.
Correct Answer
B. Re-address the entire network.Explanation
"A number of points are worth emphasizing in relation to VLSM:
Start with the shortest mask. Plan the subnets that support the most hosts. This is typically the mask used on most or all of the LAN segments.
Choose one or more available subnets and subnet further. This is sometimes called “subnetting the subnets.” It is important to remember that this can be done only with one or more subnets that have not already been used up.
Aim to use contiguous subnets where possible. Although it is not essential, it certainly makes very good sense to choose a continuous range of addresses and apply a particular mask to them. The advantage of this type of consistency is that it can be determined from the third octet address that this is a LAN segment and also that the mask is 24-bit." Page 2-17Rate this question:

What mechanism allows for easier Internet protocol version 6 (IPv6) address allocations?
- A.
Auto-sense.
- B.
Auto negotiation.
- C.
Auto configuration.
- D.
Auto summarization.
Correct Answer
C. Auto configuration.Explanation
"A problem with a 32 hexadecimal address is assigning them correctly; it’s easy to mistype a character. IPv6 uses dynamic host configuration protocol (DHCP) similar to IPv4 but there’s another option to acquire an IPv6 address, and it is called autoconfiguration. In autoconfiguration, the host appends the prefix information of its closest router to its own unique hardware or media access control (MAC) address to make up the IPv6 address, making it easier to allocate addresses."

Teredo has four tunneling components. Which one is not one of them?
- A.
Teredo host-specific relay.
- B.
Teredo client.
- C.
Teredo server.
- D.
Teredo agent.
Correct Answer
D. Teredo agent.Explanation
"-Teredo client is an IPv6/IPv4 node that supports a Teredo tunneling interface through which packets are tunneled to either other Teredo clients or nodes on the IPv6 Internet (via a Teredo relay). A Teredo
client communicates with a Teredo server to obtain an address prefix from which a Teredo-based IPv6 address is configured or to help initiate communication with other Teredo clients or hosts on the IPv6 Internet.
-A Teredo server is a IPv6/IPv4 node that is connected to both an IPv4 network and a IPv6 network, and acts as a Teredo tunneling interface over which packets are received. The role of the Teredo server is to assist in the address configuration of the Teredo client and to facilitate the initial communication between Teredo clients and other Teredo clients or between Teredo clients and IPv6-only hosts. The Teredo server listens on UDP port 3544 for Teredo traffic.
-A Teredo relay is an IPv6/IPv4 router that can forward packets between Teredo clients on the IPv4 network, using a Teredo tunneling interface, and IPv6-only hosts. The Teredo relay interacts with a Teredo server to help it facilitate initial communication between Teredo clients and IPv6-only hosts. The Teredo relay listens on UDP port 3544 for Teredo traffic.
-A Teredo host-specific relay is an IPv6/IPv4 node that has an interface and connectivity to both the IPv4 Internet and the IPv6 Internet and can communicate directly with Teredo clients over the IPv4 Internet, without the need for an intermediate Teredo relay."Pages 2-21 through 2-22Rate this question:
