LPIC-3 Exam 303 (Security) — Question 13

Which of the following resources of a shell and its child processes can be controlled by the Bash build-in command ulimit? (Choose THREE correct answers.)

Answer options

• A. The maximum size of written files
• B. The maximum number of open file descriptors
• C. The maximum number of newly created files
• D. The maximum number of environment variables
• E. The maximum number of user processes

Correct answer: A, B, E

Explanation

The correct options are A, B, and E because ulimit can limit the maximum size of files that can be written (A), the number of file descriptors that can be opened (B), and the total number of user processes (E). Options C and D are incorrect as ulimit does not control the number of newly created files or the number of environment variables.
