• A

• C

Explanation

The correct answer is C: Items will be expired only if they have a time to live value. In Azure Cosmos DB, the container-level TTL can be configured in three ways: (1) OFF - no items ever expire; (2) ON (set to -1) - TTL is enabled at the container level but no default expiration is applied; items only expire if they have their own individual 'ttl' property set; (3) ON with a specific value - all items expire after that number of seconds unless overridden. The configuration shown sets TTL to 'On' with no default (i.e., -1), which means the TTL feature is enabled, but only items that explicitly have a 'ttl' property will be deleted. Items without a 'ttl' property are retained indefinitely. This makes option C correct and eliminates options A and B (which imply a fixed expiry for all items) and option D (which implies nothing ever expires).
