RedHat EX200 Practice Test 38

Question 370

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator builds a filename from `date` in a script, but a newline and unquoted variable affect the result. Which observation best confirms the intended outcome?

  1. One correctly named file appears with the intended date suffix.
  2. Installed and absent packages take different branches correctly.
  3. The reported count equals the number of processed records.
  4. The single intended file is created under the full path.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: An administrator builds a filename from `date` in a script, but a newline and unquoted variable affect the result. Underlying reason: Command substitution produces text that is still subject to later shell expansion. The most direct, approved resolution is: Capture the formatted output into a variable and quote the expansion in path operations. Confirm it by checking: One correctly named file appears with the intended date suffix. Sustain the fix by: Test generated paths before using redirects. This is the INTENDED response for the strongest objective verification result. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Incorrect Answers

B:

Installed and absent packages take different branches correctly. That is not sufficient for the reported RHEL task, because command substitution produces text that is still subject to later shell expansion.

C:

The reported count equals the number of processed records. That is not sufficient for the reported RHEL task, because command substitution produces text that is still subject to later shell expansion.

D:

The single intended file is created under the full path. That is not sufficient for the reported RHEL task, because command substitution produces text that is still subject to later shell expansion.

Question 371

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator builds a filename from `date` in a script, but a newline and unquoted variable affect the result. Which system administration principle best explains this behavior?

  1. Package manager exit status provides a direct existence test.
  2. A piped loop can run in a separate shell environment.
  3. Command substitution produces text that is still subject to later shell expansion.
  4. Unquoted positional expansions are subject to word splitting and globbing.

Question 372

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator builds a filename from `date` in a script, but a newline and unquoted variable affect the result. Which ongoing practice best prevents a recurrence?

  1. Test generated paths before using redirects.
  2. Validate predicates against real installed and missing packages.
  3. Test stateful loop counters with multiple records.
  4. Include paths with spaces in argument validation tests.

Question 373

Original unofficial RHEL 10 RHCSA skill-check scenario: A backup script reports success whenever `tar` prints a completion message even if the command exits nonzero. Which action best addresses this situation?

  1. Stop on failed prerequisites using explicit status checks and a safe error branch.
  2. Test the `tar` exit status and verify the archive can be listed before marking the backup successful.
  3. Branch on the documented zero and nonzero grep statuses and handle read errors separately.
  4. Pass validated arguments directly to the intended command without `eval` string re-evaluation.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A backup script reports success whenever `tar` prints a completion message even if the command exits nonzero. Underlying reason: Human-readable progress output is not a guarantee of program success. The most direct, approved resolution is: Test the `tar` exit status and verify the archive can be listed before marking the backup successful. Confirm it by checking: Failed archive operations generate alerts rather than success records. Sustain the fix by: Monitor exit codes and restore tests.

Question 374

Original unofficial RHEL 10 RHCSA skill-check scenario: A backup script reports success whenever `tar` prints a completion message even if the command exits nonzero. Which observation best confirms the intended outcome?

  1. Failed archive operations generate alerts rather than success records.
  2. The destructive action is skipped when its input validation fails.
  3. Match, no-match and file-read failure have the intended outcomes.
  4. Approved service names work while shell metacharacters are rejected as data.

Question 375

Original unofficial RHEL 10 RHCSA skill-check scenario: A backup script reports success whenever `tar` prints a completion message even if the command exits nonzero. Which system administration principle best explains this behavior?

  1. Command sequencing alone does not enforce dependency success.
  2. Search commands communicate conditions through exit statuses.
  3. Human-readable progress output is not a guarantee of program success.
  4. A second shell evaluation can turn user input into unintended commands.

Question 377

Original unofficial RHEL 10 RHCSA skill-check scenario: A scheduled script runs commands sequentially but ignores a failed prerequisite and then performs a destructive step. Which action best addresses this situation?

  1. Test the `tar` exit status and verify the archive can be listed before marking the backup successful.
  2. Check the number of positional arguments and exit with usage information when the required path is missing.
  3. Stop on failed prerequisites using explicit status checks and a safe error branch.
