Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 12

A customer is concerned about mesh backhaul link security. Which level of encryption does the backhaul link use?

Answer options

• A. hash
• B. AES
• C. WEP
• D. 3DES

Correct answer: B

Explanation

The correct answer is B, AES, which is a strong encryption standard widely used for securing data. The other options, while they are encryption methods, do not provide the same level of security; WEP is outdated and insecure, hash functions do not encrypt data but verify integrity, and 3DES, though stronger than WEP, is less efficient and considered outdated compared to AES.
