True Statements about IPv6 Address fd14:920b:f83d:4079::/64 - Cisco Exam 200-125

BCF

The given IPv6 address is fd14:920b:f83d:4079::/64. Here are the explanations for each option:

A. The subnet ID is 14920bf83d: The subnet ID is the second 16-bit block of an IPv6 address. In this case, the second 16-bit block is 920b, so this statement is false.

B. The subnet ID is 4079: The subnet ID is the fourth 16-bit block of an IPv6 address. In this case, the fourth 16-bit block is 4079, so this statement is true.

C. The global ID is 14920bf83d: The global ID is the first 40 bits of an IPv6 address, which identifies a global routing prefix assigned by an Internet Registry. In this case, the global ID is fd14:920b:f83d, so this statement is false.

D. The address is a link-local address: Link-local addresses are used for communication within a single subnet and have a prefix of fe80::. In this case, the prefix is fd14::/64, so this statement is false.

E. The global ID is 4079: As mentioned above, the global ID is the first 40 bits of an IPv6 address. In this case, the global ID is fd14:920b:f83d, so this statement is false.

F. The address is a unique local address: Unique local addresses are used for local communication within an organization or between multiple organizations. They have a prefix of fc00::/7. In this case, the prefix is fd::/8, which is within the range of unique local addresses, so this statement is true.

Therefore, the correct statements are B, F, and either A or C depending on how the subnet ID is defined.
