RedHat EX200 Practice Test 61

Question 600

Original unofficial RHEL 10 RHCSA skill-check scenario: An operator tries to allocate a larger LV than the VG can currently support. Which ongoing practice best prevents a recurrence?

  1. Verify free extents and target names before LV creation.
  2. Record PV-to-VG mappings after host migrations.
  3. Maintain storage growth reserves for critical services.
  4. Use non-destructive capacity checks before swap provisioning.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: An operator tries to allocate a larger LV than the VG can currently support. Underlying reason: LV allocation is limited by available physical extents in its VG. The most direct, approved resolution is: Inspect `vgs` free capacity and choose an approved size or extend the VG first. Confirm it by checking: LV creation completes without depleting reserved storage capacity. Sustain the fix by: Maintain storage growth reserves for critical services. 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:

Verify free extents and target names before LV creation. That is not sufficient for the reported RHEL task, because LV allocation is limited by available physical extents in its VG.

B:

Record PV-to-VG mappings after host migrations. That is not sufficient for the reported RHEL task, because LV allocation is limited by available physical extents in its VG.

D:

Use non-destructive capacity checks before swap provisioning. That is not sufficient for the reported RHEL task, because LV allocation is limited by available physical extents in its VG.

Question 601

Original unofficial RHEL 10 RHCSA skill-check scenario: An application cannot locate its newly created LV because the administrator refers to an incorrect mapper path. Which action best addresses this situation?

  1. Identify the canonical path with `lvs -o lv_path` and update the intended mount configuration.
  2. Inspect `vgs` free capacity and choose an approved size or extend the VG first.
  3. Inspect `pvs` and select only unassigned, approved PVs for the requested group.
  4. Calculate partition boundaries using the actual disk geometry and update only the approved unused device.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: An application cannot locate its newly created LV because the administrator refers to an incorrect mapper path. Underlying reason: Device-mapper names are derived from VG and LV identities. The most direct, approved resolution is: Identify the canonical path with `lvs -o lv_path` and update the intended mount configuration. Confirm it by checking: The path resolves to the correct block device and the application mount succeeds. Sustain the fix by: Prefer verified identifiers over guessed `/dev/mapper` paths. 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 602

Original unofficial RHEL 10 RHCSA skill-check scenario: An application cannot locate its newly created LV because the administrator refers to an incorrect mapper path. Which observation best confirms the intended outcome?

  1. LV creation completes without depleting reserved storage capacity.
  2. The path resolves to the correct block device and the application mount succeeds.
  3. Each PV belongs to the intended VG and no live group loses membership.
  4. Partition sizes match the planned data and swap allocation without overlap.

Question 603

Original unofficial RHEL 10 RHCSA skill-check scenario: An application cannot locate its newly created LV because the administrator refers to an incorrect mapper path. Which system administration principle best explains this behavior?

  1. LV allocation is limited by available physical extents in its VG.
  2. Device-mapper names are derived from VG and LV identities.
  3. A physical volume cannot simultaneously be an independent member of competing VGs.
  4. GPT partitions divide physical address ranges that cannot safely overlap.

Question 605

Original unofficial RHEL 10 RHCSA skill-check scenario: A retired test volume remains mounted and an operator plans to delete it with `lvremove` immediately. Which action best addresses this situation?

  1. Inspect configuration files, fstab, and service dependencies before decommissioning.
  2. Identify consumers, unmount safely, verify backups and only then remove the approved obsolete LV.
  3. Verify it is unused and initialize the intended device with `pvcreate` under change approval.
  4. Identify the correct disk with current stable metadata and inspect its GPT partition names.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A retired test volume remains mounted and an operator plans to delete it with `lvremove` immediately. Underlying reason: Removing a logical volume destroys its data and active references must be addressed. The most direct, approved resolution is: Identify consumers, unmount safely, verify backups and only then remove the approved obsolete LV. Confirm it by checking: `lvs` no longer lists the target while remaining LVs are unchanged. Sustain the fix by: Require approval and dependency review before LV deletion. 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 606

Original unofficial RHEL 10 RHCSA skill-check scenario: A retired test volume remains mounted and an operator plans to delete it with `lvremove` immediately. Which observation best confirms the intended outcome?

  1. No automation attempts to use the removed volume and required data has been preserved.
  2. `pvs` shows the newly initialized PV with the expected size.
  3. The operation targets the correct partition without relying on an unrelated host's device order.
  4. `lvs` no longer lists the target while remaining LVs are unchanged.

  1. Removing a logical volume destroys its data and active references must be addressed.
  2. Inactive device state does not prove absence of business dependencies.
  3. An ordinary block device is not an LVM physical volume until initialized.
  4. Kernel disk enumeration can vary between boots and systems.

Question 609

Original unofficial RHEL 10 RHCSA skill-check scenario: A script selects an LV by an ambiguous short name that exists in two different VGs. Which action best addresses this situation?

  1. Clean obsolete mount references safely and validate fstab after approved VG decommissioning.
  2. Create the correctly named LV using `lvcreate -L 3G -n appdata vgapps` on the approved group.
  3. Review the desired extent size before VG creation or plan a supported migration rather than changing geometry blindly.
  4. Use the verified full `vg/lv` identifier and confirm its mount and ownership before removal.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A script selects an LV by an ambiguous short name that exists in two different VGs. Underlying reason: LV names are unique within a volume group, not globally. The most direct, approved resolution is: Use the verified full `vg/lv` identifier and confirm its mount and ownership before removal. Confirm it by checking: Only the approved volume disappears and the identically named LV elsewhere remains. Sustain the fix by: Log full VG/LV identifiers in destructive requests. 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 610

Original unofficial RHEL 10 RHCSA skill-check scenario: A script selects an LV by an ambiguous short name that exists in two different VGs. Which observation best confirms the intended outcome?

  1. `mount -a` or the relevant validation reports no missing-volume errors.
  2. `lvs` shows the intended LV name and approximate allocated capacity.
  3. The new or migrated group has the intended extent configuration without data loss.
  4. Only the approved volume disappears and the identically named LV elsewhere remains.
