LPIC-2 Exam 202 (Linux Engineer) — Question 58

What is DNSSEC used for?

Answer options

• A. Encrypted DNS queries between nameservers
• B. Cryptographic authentication of DNS zones
• C. Secondary DNS queries for local zones
• D. Authentication of the user that initiated the DNS query
• E. Encrypting DNS queries and answers

Correct answer: B

Explanation

DNSSEC is primarily designed for cryptographic authentication of DNS zones, ensuring that the responses to DNS queries are authentic and have not been tampered with. The other options, while related to DNS, do not accurately describe the specific function of DNSSEC, which does not focus on encrypting queries or authenticating users.
