CCNA: Cisco Certified Network Associate — Question 759

Which IPv6 address range is suitable for anycast addresses for distributed services such as DHCP or DNS?

Answer options

• A. FF00:1/12
• B. 2001:db8:0234:ca3e::1/128
• C. FE80::1/10
• D. 2002:db84:3f30:ca84:be76:2/64

Correct answer: B

Explanation

The correct answer is B, as 2001:db8::/32 is designated for documentation and examples, including anycast addresses. Option A (FF00:1/12) is a multicast address range, while option C (FE80::1/10) is for link-local addresses, and option D (2002:db84:3f30:ca84:be76:2/64) is used for 6to4 addresses, none of which serve as suitable ranges for anycast.
