RedHat EX200 Practice Test 54

Question 530

Original unofficial RHEL 10 RHCSA skill-check scenario: A new data disk has an old partition table and the team assumes it is blank without checking. Which observation best confirms the intended outcome?

  1. The new disk shows the intended GPT partition while the root disk remains unchanged.
  2. The PV and VG inventories show their actual independent states.
  3. The approved disk has the intended GPT layout and no protected partitions were altered.
  4. `pvs` shows the newly initialized PV with the expected size.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A new data disk has an old partition table and the team assumes it is blank without checking. Underlying reason: Partition table modification may make existing data inaccessible. The most direct, approved resolution is: Inspect the existing disk layout and obtain authorization before modifying any partition table. Confirm it by checking: The approved disk has the intended GPT layout and no protected partitions were altered. Sustain the fix by: Record disk layout snapshots before partition operations. 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 new disk shows the intended GPT partition while the root disk remains unchanged. That is not sufficient for the reported RHEL task, because partition table modification may make existing data inaccessible.

B:

The PV and VG inventories show their actual independent states. That is not sufficient for the reported RHEL task, because partition table modification may make existing data inaccessible.

D:

`pvs` shows the newly initialized PV with the expected size. That is not sufficient for the reported RHEL task, because partition table modification may make existing data inaccessible.

Question 531

Original unofficial RHEL 10 RHCSA skill-check scenario: A new data disk has an old partition table and the team assumes it is blank without checking. Which system administration principle best explains this behavior?

  1. Partition table modification may make existing data inaccessible.
  2. Device names are not reliable evidence of which disk is safe to partition.
  3. Physical volume and volume group are different layers in the LVM model.
  4. An ordinary block device is not an LVM physical volume until initialized.

Question 532

Original unofficial RHEL 10 RHCSA skill-check scenario: A new data disk has an old partition table and the team assumes it is blank without checking. Which ongoing practice best prevents a recurrence?

  3. Confirm the absence of important data before `pvcreate`.
  4. Record disk layout snapshots before partition operations.

Question 533

Original unofficial RHEL 10 RHCSA skill-check scenario: A technician creates a partition with the wrong ending sector and leaves insufficient room for planned swap. Which action best addresses this situation?

  1. Request a supported partition table reread or use an approved restart when the device is safely idle.
  2. Replace the fragile device name with its verified filesystem UUID or unique label in `/etc/fstab`.
  3. Inspect configuration files, fstab, and service dependencies before decommissioning.
  4. Calculate partition boundaries using the actual disk geometry and update only the approved unused device.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A technician creates a partition with the wrong ending sector and leaves insufficient room for planned swap. Underlying reason: GPT partitions divide physical address ranges that cannot safely overlap. The most direct, approved resolution is: Calculate partition boundaries using the actual disk geometry and update only the approved unused device. Confirm it by checking: Partition sizes match the planned data and swap allocation without overlap. Sustain the fix by: Validate a disk layout map before provisioning.

  2. Partition sizes match the planned data and swap allocation without overlap.
  3. The intended filesystem mounts at the correct path after reboot.
  4. No automation attempts to use the removed volume and required data has been preserved.

Question 535

Original unofficial RHEL 10 RHCSA skill-check scenario: A technician creates a partition with the wrong ending sector and leaves insufficient room for planned swap. Which system administration principle best explains this behavior?

Question 537

Original unofficial RHEL 10 RHCSA skill-check scenario: A tool updates a partition table but the running kernel still reports the old partition list. Which action best addresses this situation?

  1. Identify the correct disk with current stable metadata and inspect its GPT partition names.
  2. Migrate or release allocated extents through supported procedures before reducing VG membership.
