LPIC-2 Exam 202 (Linux Engineer) — Question 59

In a BIND zone file, what does the @ character indicate?

Answer options

• A. It's the fully qualified host name of the DNS server
• B. It's an alias for the e-mail address of the zone master
• C. It's the name of the zone as defined in the zone statement in named.conf
• D. It's used to create an alias between two CNAME entries

Correct answer: C

Explanation

The correct answer is C because the @ symbol is a shorthand notation that refers to the zone name defined in the zone statement within the named.conf file. Options A and B are incorrect as they refer to different concepts in DNS configuration, while D is also wrong because the @ character does not create aliases between CNAME records.
