ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 36

Which two IPv6 addresses are valid? (Choose two.)

Answer options

• A. 2020::DBB::1337:0:5709:3670
• B. 2000:::1
• C. FF01::101
• D. FE80:CD00::0:CDE:1227:0:211D:7790
• E. 0001::1:1CD0:8665:9801:96C3:C409

Correct answer: B, E

Explanation

Option B, '2000:::1', is valid because it has a single compressed segment. Option E, '0001::1:1CD0:8665:9801:96C3:C409', is also valid as it adheres to the IPv6 address format. The other options are incorrect due to improper use of the double colon or exceeding the allowed segments.
