LPIC-2 Exam 202 (Linux Engineer) — Question 92

Which netfilter table contains built-in chains called INPUT, OUTPUT and FORWARD?

Answer options

• A. ipconn
• B. filter
• C. nat
• D. default
• E. masq

Correct answer: B

Explanation

The correct answer is B, filter, as it is the netfilter table that includes the INPUT, OUTPUT, and FORWARD chains designed for managing network packets. The other options do not contain these built-in chains; for instance, the nat table is used for network address translation, while ipconn and masq are not standard netfilter tables.
