Question

Exhibit

Options

• AAll items will be deleted after one year.
• BItems stored in the collection will be retained always, regardless of the items time to live value.
• CItems stored in the collection will expire only if the item has a time to live value.
• DAll items will be deleted after one hour.

• A
  3% (1)
• C
  90% (28)
• D
  6% (2)

Explanation

The correct answer is C: Items will expire only if the item has a time to live value. This behavior occurs when the container's TTL is set to 'On (no default)' - meaning TTL is enabled at the container level, but no default expiration is set. Under this configuration, items without an individual ttl property are retained indefinitely, while items that explicitly include a ttl property will be deleted after that many seconds. Option A (deleted after one year) and D (deleted after one hour) would both require a specific default TTL value to be configured on the container. Option B describes the behavior when TTL is completely disabled.
