LPIC-2 Exam 202 (Linux Engineer) — Question 60

Which BIND option should be used to limit the IP addresses from which slave name servers may connect?

Answer options

• A. allow-zone-transfer
• B. allow-transfer
• C. allow-secondary
• D. allow-slaves
• E. allow-queries

Correct answer: B

Explanation

The correct answer is B, allow-transfer, which specifically controls the IP addresses that can request zone transfers from the primary DNS server. The other options do not serve this purpose; for instance, allow-zone-transfer is not a valid BIND option, while allow-secondary and allow-slaves are not standard terms in BIND configuration.
