RedHat EX200 Practice Test 14

Question 130

Original unofficial RHEL 10 RHCSA skill-check scenario: A team uses `sed -i` against an unfamiliar file and replaces far more occurrences than intended. Which observation best confirms the intended outcome?

  1. The service's configuration test passes and logs show a clean reload.
  2. No signed reports appear in the deletion preview or actual removal set.
  3. The file uses supported directives and validation succeeds.
  4. Only the intended configuration keys change in a before-and-after diff.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A team uses `sed -i` against an unfamiliar file and replaces far more occurrences than intended. Underlying reason: Broad text substitutions operate on every matching occurrence. The most direct, approved resolution is: Preview the substitution without in-place modification, narrow the match, then apply to a preserved copy. Confirm it by checking: Only the intended configuration keys change in a before-and-after diff. Sustain the fix by: Review diffs and expression scope before committing scripted edits. 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

A:

The service's configuration test passes and logs show a clean reload. That is not sufficient for the reported RHEL task, because broad text substitutions operate on every matching occurrence.

B:

No signed reports appear in the deletion preview or actual removal set. That is not sufficient for the reported RHEL task, because broad text substitutions operate on every matching occurrence.

C:

The file uses supported directives and validation succeeds. That is not sufficient for the reported RHEL task, because broad text substitutions operate on every matching occurrence.

Question 131

Original unofficial RHEL 10 RHCSA skill-check scenario: A team uses `sed -i` against an unfamiliar file and replaces far more occurrences than intended. Which system administration principle best explains this behavior?

  1. Broad text substitutions operate on every matching occurrence.
  2. Text editing is not equivalent to verifying a daemon's configuration grammar.
  3. Filename globs may match broader sets than their author's intent.
  4. Commands and their configuration files often have separate documentation entries.

Question 132

Original unofficial RHEL 10 RHCSA skill-check scenario: A team uses `sed -i` against an unfamiliar file and replaces far more occurrences than intended. Which ongoing practice best prevents a recurrence?

  1. Review diffs and expression scope before committing scripted edits.
  2. Make backups and syntax validation mandatory for configuration changes.
  3. Use explicit path allowlists for destructive maintenance.
  4. Link both command and file references in change procedures.

Question 133

Original unofficial RHEL 10 RHCSA skill-check scenario: A shell user writes a multiline file with `echo` and loses intended newlines and backslashes. Which action best addresses this situation?

  1. Preview the substitution without in-place modification, narrow the match, then apply to a preserved copy.
  2. Use a quoted here-document or a reliable text editor to preserve literal multiline content.
  3. Use `systemctl --help` or `man systemctl` as supported for that program.
  4. Restore least-privilege ownership and targeted directory/file modes based on the process identity.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A shell user writes a multiline file with `echo` and loses intended newlines and backslashes. Underlying reason: Shell escaping and `echo` implementation behavior can transform text unexpectedly. The most direct, approved resolution is: Use a quoted here-document or a reliable text editor to preserve literal multiline content. Confirm it by checking: The file's line endings and literal special characters match the desired configuration. Sustain the fix by: Verify generated configuration bytes before applying them.

  2. Relevant unit-management options appear in the authoritative local usage text.
  3. The file's line endings and literal special characters match the desired configuration.

Question 137

Original unofficial RHEL 10 RHCSA skill-check scenario: A configuration change fails because the editor saves to a read-only file owned by a service account. Which action best addresses this situation?

  1. Use a quoted here-document or a reliable text editor to preserve literal multiline content.
  2. Redirect standard error with `2>` to an appropriate error file or use a controlled combined stream.
  3. Plan the cross-filesystem move and validate source/destination contents before removing the original.
  4. Request appropriate approved privilege or controlled ownership access instead of weakening file permissions globally.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A configuration change fails because the editor saves to a read-only file owned by a service account. Underlying reason: Edit authorization follows filesystem ownership and effective privileges. The most direct, approved resolution is: Request appropriate approved privilege or controlled ownership access instead of weakening file permissions globally. Confirm it by checking: The file is changed by the authorized identity and retains intended restrictive permissions. Sustain the fix by: Review sensitive config ownership after every deployment.

  1. The file is changed by the authorized identity and retains intended restrictive permissions.
  2. The file's line endings and literal special characters match the desired configuration.
  3. Reproduce the failure and confirm the diagnostic is captured separately from normal output.
  4. A checksum comparison confirms the destination is complete.

Original unofficial RHEL 10 RHCSA skill-check scenario: A configuration change fails because the editor saves to a read-only file owned by a service account. Which system administration principle best explains this behavior?

  1. Shell escaping and `echo` implementation behavior can transform text unexpectedly.
  2. File descriptor 2 carries error messages independently of standard output.
  3. Edit authorization follows filesystem ownership and effective privileges.
  4. A move across filesystems can involve copy-and-delete rather than a single rename.
