RedHat EX200 Practice Test 113

Question 1120

Original unofficial RHEL 10 RHCSA skill-check scenario: A remote user's `.ssh` directory is world-writable, and public-key login is rejected by secure SSH settings. Which ongoing practice best prevents a recurrence?

  1. Audit key-directory ownership and modes after restores.
  2. Ban private-key copying in access setup procedures.
  3. Verify representative nested labels after data moves.
  4. Document business justification for each enabled Boolean.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: A remote user's `.ssh` directory is world-writable, and public-key login is rejected by secure SSH settings. Underlying reason: SSH permission checks protect the integrity of authorized key material. The most direct, approved resolution is: Restore approved ownership and restrictive `.ssh` and `authorized_keys` modes. Confirm it by checking: The SSH server accepts the approved key without weakening server authentication policy. Sustain the fix by: Audit key-directory ownership and modes after restores. 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

B:

Ban private-key copying in access setup procedures. That is not sufficient for the reported RHEL task, because SSH permission checks protect the integrity of authorized key material.

C:

Verify representative nested labels after data moves. That is not sufficient for the reported RHEL task, because SSH permission checks protect the integrity of authorized key material.

D:

Document business justification for each enabled Boolean. That is not sufficient for the reported RHEL task, because SSH permission checks protect the integrity of authorized key material.

Question 1121

Original unofficial RHEL 10 RHCSA skill-check scenario: A help desk proposes copying a user's private key onto the server to fix public-key authentication. Which action best addresses this situation?

  1. Restore approved ownership and restrictive `.ssh` and `authorized_keys` modes.
  2. Inspect the denial and correct its supported labeling or Boolean cause while keeping enforcing mode.
  3. Keep private keys only with the owner and distribute the corresponding public key to the server.
  4. Replace the temporary label change with a supported persistent `semanage fcontext` policy and restore labels.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A help desk proposes copying a user's private key onto the server to fix public-key authentication. Underlying reason: Public-key authentication relies on proving possession of a private key, not sharing it. The most direct, approved resolution is: Keep private keys only with the owner and distribute the corresponding public key to the server. Confirm it by checking: Key authentication works while no private key is present on the destination. Sustain the fix by: Ban private-key copying in access setup procedures. 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:

Restore approved ownership and restrictive `.ssh` and `authorized_keys` modes. That is not sufficient for the reported RHEL task, because public-key authentication relies on proving possession of a private key, not sharing it.

B:

Inspect the denial and correct its supported labeling or Boolean cause while keeping enforcing mode. That is not sufficient for the reported RHEL task, because public-key authentication relies on proving possession of a private key, not sharing it.

D:

Question 1122

Original unofficial RHEL 10 RHCSA skill-check scenario: A help desk proposes copying a user's private key onto the server to fix public-key authentication. Which observation best confirms the intended outcome?

  1. The SSH server accepts the approved key without weakening server authentication policy.
  2. The service works and `getenforce` still reports Enforcing.
  3. Key authentication works while no private key is present on the destination.
  4. The intended file type survives relabel and reboot tests.

Question 1123

Original unofficial RHEL 10 RHCSA skill-check scenario: A help desk proposes copying a user's private key onto the server to fix public-key authentication. Which system administration principle best explains this behavior?

  1. SSH permission checks protect the integrity of authorized key material.
  2. SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement.
  3. `chcon` does not establish a durable file-context policy rule.
  4. Public-key authentication relies on proving possession of a private key, not sharing it.

  3. Require AVC analysis before policy exceptions.
  4. Prefer persistent mapping changes for required custom paths.

Question 1125

Original unofficial RHEL 10 RHCSA skill-check scenario: A web admin runs `setenforce 0` to resolve an access failure and assumes the change will remain across reboot. Which action best addresses this situation?

  1. Inspect the denial and correct its supported labeling or Boolean cause while keeping enforcing mode.
  2. Diagnose the denial and restore enforcing with a persistent approved SELinux configuration rather than leaving permissive troubleshooting state.
  3. Use `restorecon` on the approved web directory when the default file-context policy applies.
  4. Restore approved ownership and restrictive `.ssh` and `authorized_keys` modes.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A web admin runs `setenforce 0` to resolve an access failure and assumes the change will remain across reboot. Underlying reason: Runtime SELinux mode and persisted config are separate settings. The most direct, approved resolution is: Diagnose the denial and restore enforcing with a persistent approved SELinux configuration rather than leaving permissive troubleshooting state. Confirm it by checking: `getenforce` reports Enforcing after restart and the service functions with corrected policy. Sustain the fix by: Audit persistent enforcing status after emergency troubleshooting. 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;

A:

Inspect the denial and correct its supported labeling or Boolean cause while keeping enforcing mode. That is not sufficient for the reported RHEL task, because runtime SELinux mode and persisted config are separate settings.

Question 1126

Original unofficial RHEL 10 RHCSA skill-check scenario: A web admin runs `setenforce 0` to resolve an access failure and assumes the change will remain across reboot. Which observation best confirms the intended outcome?

  1. The service works and `getenforce` still reports Enforcing.
  2. `ls -Z` shows the expected web-content type and HTTP access succeeds.
  3. `getenforce` reports Enforcing after restart and the service functions with corrected policy.
  4. The SSH server accepts the approved key without weakening server authentication policy.

Question 1127

  1. SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement.
  2. Files relocated from unusual directories can retain labels inappropriate for their new purpose.
