Introducing Cisco Data Center Networking (DCICN) — Question 46

Which three addresses are valid forms of an IPv6 Address:
2001:0DB8:0000:FE01:0000:0000:0000:0000? (Choose three.)

Answer options

• A. 2001:0DB8:0000:FE01::
• B. 2001:DB8:0:FE01::
• C. 2001:0DB8::FE01::
• D. 2001:DB8:0:FE01:0:0:0:0

Correct answer: A, B, D

Explanation

Option A is valid as it uses the double colon for compression correctly. Option B is also valid because it compresses the leading zeros appropriately. Option D is valid as well, as it maintains the correct format. Option C is incorrect because it contains a double colon in an invalid location, which makes it an improper format.
