RedHat EX200 Practice Test 88

Question 870

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator manually sets the correct clock but the system drifts again after several days. Which observation best confirms the intended outcome?

  1. Events align when converted to a common timezone and the clocks report healthy sync.
  2. Clock offset remains within the defined tolerance over repeated checks.
  3. The service starts and no executable-not-found errors appear.
  4. DNF resolves the supported updates and the installed package versions change as approved.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: An administrator manually sets the correct clock but the system drifts again after several days. Underlying reason: One-time clock correction does not provide continuous time discipline. The most direct, approved resolution is: Enable and configure the supported chrony time service for ongoing synchronization. Confirm it by checking: Clock offset remains within the defined tolerance over repeated checks. Sustain the fix by: Validate time-client service after commissioning. 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:

Events align when converted to a common timezone and the clocks report healthy sync. That is not sufficient for the reported RHEL task, because one-time clock correction does not provide continuous time discipline.

C:

The service starts and no executable-not-found errors appear. That is not sufficient for the reported RHEL task, because one-time clock correction does not provide continuous time discipline.

D:

DNF resolves the supported updates and the installed package versions change as approved. That is not sufficient for the reported RHEL task, because one-time clock correction does not provide continuous time discipline.

Question 871

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator manually sets the correct clock but the system drifts again after several days. Which system administration principle best explains this behavior?

  1. One-time clock correction does not provide continuous time discipline.
  2. Timezone formatting does not change the underlying instant represented by UTC.
  3. A unit's ExecStart path must resolve before networking policy matters.
  4. Package updates require reachable trusted content sources and appropriate access rights.

Question 872

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator manually sets the correct clock but the system drifts again after several days. Which ongoing practice best prevents a recurrence?

  1. Validate time-client service after commissioning.
  2. Standardize UTC correlation and document local display zones.
  3. Validate executable locations in unit deployment tests.
  4. Check repository access before security patch windows.

Question 873

Original unofficial RHEL 10 RHCSA skill-check scenario: A host uses a time server blocked by its local firewall and starts rejecting time-dependent authentication. Which action best addresses this situation?

  1. Enable and configure the supported chrony time service for ongoing synchronization.
  2. Restore `graphical.target` as the approved default and verify display services are installed and enabled.
  3. Verify source reachability and approve the necessary NTP client traffic without exposing unrelated services.
  4. Reload the systemd manager before restarting the affected unit under change control.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A host uses a time server blocked by its local firewall and starts rejecting time-dependent authentication. Underlying reason: Network restrictions can prevent an otherwise configured time client from synchronizing. The most direct, approved resolution is: Verify source reachability and approve the necessary NTP client traffic without exposing unrelated services. Confirm it by checking: Chrony reports a usable source and authentication timestamps stabilize. Sustain the fix by: Include NTP reachability in network policy reviews.

Question 875

Original unofficial RHEL 10 RHCSA skill-check scenario: A host uses a time server blocked by its local firewall and starts rejecting time-dependent authentication. Which system administration principle best explains this behavior?

Question 877

Original unofficial RHEL 10 RHCSA skill-check scenario: A log analyst correlates time stamps across servers but mistakes their displayed timezone differences for clock drift. Which action best addresses this situation?

  1. Configure approved NTP sources in chrony and verify synchronization using `chronyc sources` and `tracking`.
  2. Configure an approved local package source and use `dnf` to update from that source.

Question 878

Original unofficial RHEL 10 RHCSA skill-check scenario: A log analyst correlates time stamps across servers but mistakes their displayed timezone differences for clock drift. Which observation best confirms the intended outcome?

  3. The job reads authorized logs without a blanket permission expansion.
  4. Events align when converted to a common timezone and the clocks report healthy sync.
