CCNA Routing and Switching (legacy) — Question 111

In which two formats can the IPv6 address fd15:0db8:0000:0000:0700:0003:400F:572B be written? (Choose two.)

Answer options

• A. fd15:0db8:0000:0000:700:3:400F:527B
• B. fd15::db8::700:3:400F:527B
• C. fd15:db8:0::700:3:4F:527B
• D. fd15:0db8::7:3:4F:527B
• E. fd15:db8::700:3:400F:572B

Correct answer: A, E

Explanation

Option A is correct because it compresses the IPv6 address by omitting leading zeros, which is a valid representation. Option E is also correct as it uses the double colon (::) to represent consecutive sections of zeros, which is another valid format. The other options either have incorrect zero compression or do not maintain the integrity of the original address.
