  1. Which command is used to back up a Cinder volume to Swift?

    Answer: openstack volume backup create

    `openstack volume backup create` triggers the Cinder backup service to copy volume data to the configured backup backend (typically Swift).

  2. A Swift Dynamic Large Object (DLO) differs from a Static Large Object (SLO) in that DLO:

    Answer: Automatically assembles segments matching a common prefix without an explicit manifest

    DLO uses a prefix-based discovery of segments (no explicit manifest), while SLO requires a manifest JSON file listing each segment's container, path, ETag, and size.

  3. Which Glance property must be set to allow all OpenStack projects to use an image without being its owner?

    Answer: visibility: public

    Setting `visibility: public` on a Glance image makes it available to all projects in the OpenStack deployment, not just the owner's project.

  4. An administrator wants to prevent accidental deletion of a critical Glance image. Which property should be set?

    Answer: protected: true

    Setting `protected: true` on a Glance image prevents it from being deleted until the protected flag is first set back to false.

  5. Which OpenStack service should be used to manage credentials and certificates needed for volume-level data encryption?

    Answer: Barbican

    Barbican (Key Manager service) securely stores and manages the encryption keys and certificates required by Cinder for volume-level encryption.

  6. What happens to Manila shares when the share network associated with them is deleted?

    Answer: The deletion fails if shares are still using the share network

    Manila prevents deletion of a share network that still has active shares associated with it, returning an error until those shares are deleted first.

  7. To expose a Cinder volume's data to an instance via iSCSI, which component on the storage node is responsible for managing iSCSI targets?

    Answer: Cinder volume service with an iSCSI target helper (tgtd or LIO)

    The Cinder volume service uses an iSCSI target helper such as tgtd, LIO, or ISCSI to create and manage iSCSI targets that expose block devices to compute nodes.
