Question 1

Which CORRECTLY reflects the process of IP delegation to SDSU?

Accepted Answer

The process of IP delegation starts with IANA delegating IP addresses to the Regional Internet Registry (RIR), in this case, F1S1S1W1 to F1F1F10. After this, the RIR delegates a subset of IP addresses to an Internet Service Provider (ISP) within their region, which in turn delegates a subset of IP addresses to their customers, one of which is SDSU. Therefore, the correct order is IANA → RIR → ISP → SDSU. Option B correctly reflects this sequence.

Question 2

Assume a company with network IP address of 16 bits. Seven subnets should be created within a firm and the network administrator decided to borrow a minimal number of bits from the host part for the subnet creation. What is the subnet mask?

Accepted Answer

To create seven subnets, you need at least three bits (2^3 = 8, providing 8 subnets). Starting with a base mask of 255.255.0.0 (for 16 network bits), borrowing 3 bits for subnetting changes the mask to 255.255.224.0 (11100000 in the third octet).

Question 3

In the classful addressing scheme, when the first octet (number) of a network is 179, it is a ________ .

Accepted Answer

In the classful addressing scheme, the first octet determines the class of the network. For a first octet of 179, which falls within the range of 128 to 191, it is classified as a Class B network.

Question 4

Let's assume that a university network (130.191.0.0) uses a subnet mask 11111111.11111111.11111100.00000000 to assign a unique subnet to each college. How many college subnets can be created with the IP addressing scheme.

Accepted Answer

The answer of Let's assume that a university network (130.191.0.0)...

Question 5

____ computers can have a permanent (or static) IP address in a classless network with the /24 prefix. Exclude all 1s and all 0s from the counting of host IPs.

Accepted Answer

In a classless network with /24 prefix, there are 24 bits for the network and 8 bits for the host. Since we need to exclude all 0s and all 1s from the counting of host IPs, we have a total of 2^8 - 2 = 254 possible host IPs. Therefore, the best choice is B.

Question 6

What is the binary bit stream equivalent to the decimal value 191?

Accepted Answer

To convert decimal to binary, we need to divide the given decimal number by 2 until the quotient becomes 0. We write the remainder in each division to get the binary equivalent. In this case, 191 divided by 2 gives a quotient of 95 and remainder of 1. Dividing 95 by 2 gives a quotient of 47 and remainder of 1. Dividing 47 by 2 gives a quotient of 23 and remainder of 1. Dividing 23 by 2 gives a quotient of 11 and remainder of 1. Dividing 11 by 2 gives a quotient of 5 and remainder of 1. Dividing 5 by 2 gives a quotient of 2 and remainder of 1. Dividing 2 by 2 gives a quotient of 1 and remainder of 0. Dividing 1 by 2 gives a quotient of 0 and remainder of 1. So, the binary equivalent of 191 is 10111111.

Question 7

Question 8

The following measures should help in extending the IPv4's life expectancy EXCEPT:

Accepted Answer

The use of switches instead of routers in networking does not directly affect the lifespan of IPv4 addresses. The other options all pertain to conserving IPv4 addresses and/or allowing multiple devices to share a single IPv4 address.

Question 9

Which CORRECTLY describes the network address translation?

Accepted Answer

Network Address Translation (NAT) allows a network to use private IP addresses internally and still communicate with the internet. By using NAT, a network can use a single or a few public IP addresses to represent multiple private IP addresses, thus conserving public IP addresses. This makes it possible to allocate IP space more generously within the private network, anticipating future growth, without concern for the scarcity of public IP addresses.

Question 10

Question 14

The following are descriptions of the IPv6 standard EXCEPT:

Accepted Answer

Option D is the only incorrect statement as an IPv6 stack can coexist with an IPv4 stack on the same device. All other statements are true, such as Option A - IPv6 uses 128-bit addressing, Option B - IPv6 uses 64 bits to represent the subnet and another 64 bits for the host address, Option C - IPv6 supports the incorporation of MAC address in the IP address, and Option E - IPv4 address can be converted to IPv6 address with the help of transition techniques.

Question 15

The following IPv6 addresses are equivalent EXCEPT:

Accepted Answer

IPv6 addresses allow for the omission of leading zeros and the substitution of a single "::" for one or more groups of 0000, but "::" can only appear once in an address. Option D incorrectly uses "::" more than once, making it not equivalent to the others.

Question 16

We are in the transition from IPv4 to IPv6. Several approaches have been introduced to make the transition. The following demonstrates ______ technical solution.

Accepted Answer

Question 17

If the following IPv6 address is reduced to the smallest: (AD89:00C0:0204:0000:0000:ABC0:000B:0000)

Accepted Answer

The address can be compressed by omitting leading zeros and consecutive blocks of zeros with two colons (::). The compressed form would be AD89:C0:204::ABC0:B:0. Choice A correctly represents the compressed form.

Question 18

The following are descriptions of the IPv6 standard EXCEPT:

Accepted Answer

The statement "A host computer has to be configured with either an IPv4 or an IPv6 address, but not both" is not true. Host computers can be configured with both IPv4 and IPv6 addresses.

All of the other statements are true:
- A) It uses 128 bit addressing that is equivalent to 32 hexadecimal digits.
- B) It uses 64 bits to represent a subnet (or network) address and 64 bits for a host address.
- C) If necessary, the IP address can be automatically derived from the host's MAC address.
- E) An IPv4 address can be converted to an IPv6 address.
