RedHat EX200 Practice Test 59

Question 580

Original unofficial RHEL 10 RHCSA skill-check scenario: A team changes a VG's planned physical extent size after it has been created and expects existing extents to resize automatically. Which ongoing practice best prevents a recurrence?

  1. Require free-extent checks before capacity allocation.
  2. Record extent-size requirements before making volume groups.
  3. Log full VG/LV identifiers in destructive requests.
  4. Require device identity and backup checks before disk changes.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A team changes a VG's planned physical extent size after it has been created and expects existing extents to resize automatically. Underlying reason: VG physical extent sizing is a creation-time design decision. The most direct, approved resolution is: Review the desired extent size before VG creation or plan a supported migration rather than changing geometry blindly. Confirm it by checking: The new or migrated group has the intended extent configuration without data loss. Sustain the fix by: Record extent-size requirements before making volume groups. 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:

Require free-extent checks before capacity allocation. That is not sufficient for the reported RHEL task, because VG physical extent sizing is a creation-time design decision.

C:

Log full VG/LV identifiers in destructive requests. That is not sufficient for the reported RHEL task, because VG physical extent sizing is a creation-time design decision.

D:

Require device identity and backup checks before disk changes. That is not sufficient for the reported RHEL task, because VG physical extent sizing is a creation-time design decision.

Question 581

Original unofficial RHEL 10 RHCSA skill-check scenario: A storage report counts total VG size as free space and a new LV allocation fails. Which action best addresses this situation?

  1. Add the approved PV to the existing VG with `vgextend` after checking its state.
  2. Query local UUIDs with `blkid` and correct the exact fstab entry.
  3. Stop and confirm the target partition's filesystem and data ownership before any destructive initialization.
  4. Use `vgs` to inspect `VFree` rather than assuming the entire pool is available.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A storage report counts total VG size as free space and a new LV allocation fails. Underlying reason: Existing logical volumes consume portions of VG capacity. The most direct, approved resolution is: Use `vgs` to inspect `VFree` rather than assuming the entire pool is available. Confirm it by checking: Planned LV sizes fit actual free extents and creation succeeds. Sustain the fix by: Require free-extent checks before capacity allocation. 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:

Question 582

Original unofficial RHEL 10 RHCSA skill-check scenario: A storage report counts total VG size as free space and a new LV allocation fails. Which observation best confirms the intended outcome?

  1. Planned LV sizes fit actual free extents and creation succeeds.
  2. `vgs` shows increased free extents and existing LVs remain available.
  3. The configured UUID maps to the intended local filesystem and mounting succeeds.
  4. The protected filesystem remains intact and only the approved spare partition becomes an LVM PV.

Explanation

Correct Answer

A:

Question 583

Original unofficial RHEL 10 RHCSA skill-check scenario: A storage report counts total VG size as free space and a new LV allocation fails. Which system administration principle best explains this behavior?

  1. Adding a PV expands the capacity pool without automatically resizing LVs.
  2. Filesystem UUIDs identify specific formatted volumes, not generic device roles.
  3. Existing logical volumes consume portions of VG capacity.
  4. PV initialization writes LVM metadata that can conflict with existing data.

Question 584

Original unofficial RHEL 10 RHCSA skill-check scenario: A storage report counts total VG size as free space and a new LV allocation fails. Which ongoing practice best prevents a recurrence?

  1. Track free VG space after each expansion.
  2. Validate identifiers on the target host before deployment.
  3. Use inventory-based target verification for all PV operations.
  4. Require free-extent checks before capacity allocation.

Question 585

Original unofficial RHEL 10 RHCSA skill-check scenario: An approved application needs a dedicated 3 GiB logical volume inside a VG with adequate free extents. Which action best addresses this situation?

  1. Inspect `lvs` and use a unique approved name instead of overwriting existing storage.
  2. Identify consumers, unmount safely, verify backups and only then remove the approved obsolete LV.
  3. Create the correctly named LV using `lvcreate -L 3G -n appdata vgapps` on the approved group.
  4. Assign unambiguous labels or prefer distinct verified UUID references.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: An approved application needs a dedicated 3 GiB logical volume inside a VG with adequate free extents. Underlying reason: LVs allocate extents from a VG and are not usable filesystems until formatted. The most direct, approved resolution is: Create the correctly named LV using `lvcreate -L 3G -n appdata vgapps` on the approved group. Confirm it by checking: `lvs` shows the intended LV name and approximate allocated capacity. Sustain the fix by: Verify free extents and target names before LV creation. 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;

  2. Both the original and new logical volumes remain intact with distinct paths.
  3. `lvs` no longer lists the target while remaining LVs are unchanged.
  4. The intended volume mounts consistently without ambiguity.

Original unofficial RHEL 10 RHCSA skill-check scenario: An approved application needs a dedicated 3 GiB logical volume inside a VG with adequate free extents. Which system administration principle best explains this behavior?

  1. LVM identifies LVs by their VG and LV names.
  2. LVs allocate extents from a VG and are not usable filesystems until formatted.
  3. Removing a logical volume destroys its data and active references must be addressed.
  4. Filesystem labels are administrator-managed and can collide.

Question 589

Original unofficial RHEL 10 RHCSA skill-check scenario: A script creates a new LV but the service cannot mount it because no filesystem exists. Which action best addresses this situation?

  1. Identify the canonical path with `lvs -o lv_path` and update the intended mount configuration.
  2. Check `lsblk`, `pvs`, and `vgs` separately before assigning or initializing any device.
  3. Confirm the intended LV, format it with an approved filesystem, and mount it safely.
  4. Verify disk identity and existing partitions with `lsblk` before creating a GPT partition on the new unused device.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A script creates a new LV but the service cannot mount it because no filesystem exists. Underlying reason: Logical volume provisioning and filesystem creation are separate tasks. The most direct, approved resolution is: Confirm the intended LV, format it with an approved filesystem, and mount it safely. Confirm it by checking: `lsblk -f` shows the new filesystem and `findmnt` reports the mounted target. Sustain the fix by: Test the complete block-device-to-filesystem workflow.

Question 590

Original unofficial RHEL 10 RHCSA skill-check scenario: A script creates a new LV but the service cannot mount it because no filesystem exists. Which observation best confirms the intended outcome?

  1. The path resolves to the correct block device and the application mount succeeds.
  2. The PV and VG inventories show their actual independent states.
  3. `lsblk -f` shows the new filesystem and `findmnt` reports the mounted target.
  4. The new disk shows the intended GPT partition while the root disk remains unchanged.
