LPIC-1 Exam 102 v5 (Linux Administrator) — Question 64

What is the purpose of TCP wrapper?

Answer options

• A. Manage and adjust bandwidth used by TCP services.
• B. Bind a network service to a TCP port.
• C. Encapsulate TCP messages in IP packets.
• D. Add SSL support to plain text TCP services.
• E. Limit access to a network service.

Correct answer: E

Explanation

The correct answer is E because TCP wrappers are specifically designed to control access to network services by allowing or denying connections based on predefined rules. The other options describe functions that are not related to the primary role of TCP wrappers, such as managing bandwidth, binding services to ports, encapsulating messages, or adding encryption.
