RedHat EX200 Practice Test 9

Question 80

Original unofficial RHEL 10 RHCSA skill-check scenario: An engineer copies a private SSH key into a shared directory to simplify a deployment. Which ongoing practice best prevents a recurrence?

  1. Track approved host-key rotation and rebuild notices.
  2. Require documented reference checks for unfamiliar destructive commands.
  3. Use explicit path allowlists for destructive maintenance.
  4. Audit private-key distribution and rotation for automation accounts.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: An engineer copies a private SSH key into a shared directory to simplify a deployment. Underlying reason: A private authentication credential must remain confidential to its holder. The most direct, approved resolution is: Move the private key to an account-controlled secure location and use correct restrictive access instead of sharing it. Confirm it by checking: The authorized owner can authenticate while other users cannot read the private key. Sustain the fix by: Audit private-key distribution and rotation for automation accounts. This is the INTENDED response for the best ongoing operational safeguard. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Incorrect Answers

A:

Track approved host-key rotation and rebuild notices. That is not sufficient for the reported RHEL task, because a private authentication credential must remain confidential to its holder.

B:

Require documented reference checks for unfamiliar destructive commands. That is not sufficient for the reported RHEL task, because a private authentication credential must remain confidential to its holder.

C:

Use explicit path allowlists for destructive maintenance. That is not sufficient for the reported RHEL task, because a private authentication credential must remain confidential to its holder.

Question 81

Original unofficial RHEL 10 RHCSA skill-check scenario: A junior admin uses `su devops` and expects every login environment variable to be refreshed. Which action best addresses this situation?

  1. Check `id`, `whoami`, and `pwd`, then use the correct target user's home path.
  2. Use `ls -l /home`, separating the `-l` option from the directory argument.
  3. Use an appropriate login shell such as `su - devops` when a complete target-user environment is required.
  4. Redirect standard error with `2>` to an appropriate error file or use a controlled combined stream.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A junior admin uses `su devops` and expects every login environment variable to be refreshed. Underlying reason: `su` and a login invocation initialize the environment differently. The most direct, approved resolution is: Use an appropriate login shell such as `su - devops` when a complete target-user environment is required. Confirm it by checking: `whoami`, home directory and login environment reflect the target account. Sustain the fix by: Specify login-shell expectations when testing another user's configuration. This is the INTENDED response for the best approved troubleshooting or configuration action. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Incorrect Answers

A:

Check `id`, `whoami`, and `pwd`, then use the correct target user's home path. That is not sufficient for the reported RHEL task, because `su` and a login invocation initialize the environment differently.

B:

Question 82

Original unofficial RHEL 10 RHCSA skill-check scenario: A junior admin uses `su devops` and expects every login environment variable to be refreshed. Which observation best confirms the intended outcome?

  1. The file is created with appropriate ownership in the intended home.
  2. The output lists the metadata for `/home` without a usage error.
  3. Reproduce the failure and confirm the diagnostic is captured separately from normal output.
  4. `whoami`, home directory and login environment reflect the target account.

Question 83

Original unofficial RHEL 10 RHCSA skill-check scenario: A junior admin uses `su devops` and expects every login environment variable to be refreshed. Which system administration principle best explains this behavior?

  1. Current identity and working directory can differ after account switching.
  2. `su` and a login invocation initialize the environment differently.
  3. Required whitespace distinguishes options from positional path operands.
  4. File descriptor 2 carries error messages independently of standard output.

Question 84

Original unofficial RHEL 10 RHCSA skill-check scenario: A junior admin uses `su devops` and expects every login environment variable to be refreshed. Which ongoing practice best prevents a recurrence?

  1. Verify identity and destination before writing shared artifacts.
  2. Specify login-shell expectations when testing another user's configuration.
  3. Validate command syntax using help before copying examples into runbooks.
  4. Include stderr handling in shell monitoring templates.

Question 85

Original unofficial RHEL 10 RHCSA skill-check scenario: An analyst must inspect an application directory as its service owner but launches the command as root unnecessarily. Which action best addresses this situation?

  1. Authenticate with a personal account and perform only approved privileged commands through configured sudo access.
  2. Inspect matching paths first and quote or narrow the glob before making changes.
  3. Use a symbolic link when a directory alias is required.
  4. Run the read-only check as the intended account with authorized `sudo -u` rather than retaining root.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: An analyst must inspect an application directory as its service owner but launches the command as root unnecessarily. Underlying reason: Effective user identity controls filesystem access independently of the shell prompt text. The most direct, approved resolution is: Run the read-only check as the intended account with authorized `sudo -u` rather than retaining root. Confirm it by checking: The command executes with the scoped service user's effective identity. Sustain the fix by: Apply least privilege for operational diagnostics. This is the INTENDED response for the best approved troubleshooting or configuration action. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Question 86

Original unofficial RHEL 10 RHCSA skill-check scenario: An analyst must inspect an application directory as its service owner but launches the command as root unnecessarily. Which observation best confirms the intended outcome?

  1. The command executes with the scoped service user's effective identity.
  2. Audit logs attribute the privileged command to the initiating identity.
  3. Preview shows only the intended file set and no backup entries.
  4. The alias traverses into the target directory without hard-linking it.

  1. Effective user identity controls filesystem access independently of the shell prompt text.
  2. Disabling direct root login does not eliminate delegated administrative privileges.
  3. Shell globbing expands filename patterns before the utility receives operands.
  4. Ordinary directory hard links are restricted to protect filesystem structure.
