LPIC-1 Exam 102 v5 (Linux Administrator) — Question 14

Which of the following is a valid IPv6 address?

Answer options

• A. 2001:db8:0g21::1
• B. 2001::db8:4581::1
• C. 2001:db8:3241::1
• D. 2001%db8%9990%%1
• E. 2001.db8.819f..1

Correct answer: C

Explanation

The correct answer is C, as it adheres to the standard hexadecimal format for IPv6 addresses. Option A contains an invalid character 'g', option B has more than one double colon, option D uses incorrect percentage signs instead of colons, and option E uses periods instead of colons, all of which make those options invalid.
