Read the first 7 Data Management & Integration flashcards as text

  1. An administrator wants to encrypt a Cinder volume at rest. What must be configured first?

    Answer: A Barbican endpoint and a volume type with encryption metadata

    Cinder volume encryption requires Barbican for key management and a volume type configured with the desired encryption provider and cipher.

  2. When migrating a Cinder volume from one backend to another using `cinder migrate`, which condition must be met?

    Answer: The volume must be in 'available' status (not attached)

    Cinder volume migration requires the volume to be in 'available' (detached) state so the data can be safely moved to the new backend.

  3. Which Swift mechanism enables automatic expiration and deletion of objects after a specified time?

    Answer: Setting X-Delete-At or X-Delete-After headers processed by the object expirer daemon

    Swift's object expirer daemon processes objects tagged with `X-Delete-At` (Unix timestamp) or `X-Delete-After` (seconds) headers, automatically deleting them at the specified time.

  4. In a Glance configuration using multiple stores, what does the `default_store` directive specify?

    Answer: The store used for image uploads when no store is explicitly requested

    `default_store` in Glance's configuration specifies which backend (e.g., rbd, file, swift) is used when an image is uploaded without an explicit store designation.

  5. A developer needs to give a time-limited URL for a private Swift object without exposing credentials. Which feature should they use?

    Answer: TempURL

    TempURL generates a time-limited, cryptographically signed URL that provides temporary access to a private Swift object without exposing account credentials.

  6. Which Cinder feature allows administrators to set guaranteed IOPS or throughput limits on volumes?

    Answer: Quality of Service (QoS) specs

    Cinder Quality of Service (QoS) specs are associated with volume types to enforce IOPS, bandwidth, or burst limits on volumes.

  7. What is the function of a Manila 'share network' object?

    Answer: Associates a Neutron network and subnet with share access for network-aware backends

    A Manila share network links a Neutron network and subnet to Manila so that network-aware backends can provision shares accessible on that network.
