When a municipal database backup completes, on-call staff should get an email or pager alert. If instead the match must resize or convert a resource, which Events actions fit those two intents?
Select an answer to reveal the explanation.
Short Explanation
Notifications is how you tell people (email, pager subscriptions). A Function is how you do work—resize, convert, call another API. Same Events rule model; different action for inform versus automate.
Full Explanation
When a municipal database backup completes and on-call staff should receive an email or pager alert, the Events action that fits is a Notifications topic whose subscriptions deliver those channels. When instead the match must resize or convert a resource, the fitting action is an Oracle Function that performs the automated work. Same Events rule model—filter then action—but inform versus automate maps to Notifications versus Functions. Treating Queue as the only Events action for both paging humans and calling APIs is incorrect: Queue is not a documented Events action destination, and it neither pages operators nor replaces Function invocation. Using a Streaming action for email delivery and a Vault action for compute resize invents capabilities those services do not provide as Events actions—Streaming fans out records; Vault stores secrets; neither emails on-call nor resizes compute by itself. An API Gateway deployment as an Events action that pages operators directly is not in the Events action catalog. Exam caveat: one rule can carry multiple actions (for example notify and invoke a Function), but each action still needs a pre-existing destination and IAM that permits Events delivery. Operational check: for an alert-only path, subscribe an email or pager endpoint to the topic and emit a test backup-complete event; for automation, point a Function action at a no-op that logs the payload, then verify both paths independently before combining them.
