Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 17

If the MAC address of an interface is 0EE0-FFFE-0FEC, the corresponding EUI-64 address is ( ).

Answer options

• A. 0CE0-FFFF-FEFE-0FEC
• B. 0EE0-FFFF-FEFE-0FEC
• C. 0EE0-FFFE-FFFE-0FEC
• D. 0CE0-FFFE-FFFE-0FEC

Correct answer: D

Explanation

The correct EUI-64 address is formed by inserting 'FFFE' in the middle of the MAC address, while also adjusting the first octet according to its universality (global or local). Option D correctly modifies the first octet to 0CE0 while adding 'FFFE' in the proper place. The other options either do not modify the first octet or incorrectly place 'FFFE'.
