Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 9

Which option contains the essential components of the Oracle Cloud Infrastructure Notifications service? (Choose the best answer.)

Answer options

• A. An ALARM with a name unique across the tenancy, a SUBSCRIPTION, and a METRIC with the measurement of interest.
• B. A TOPIC with a name unique across the tenancy, a SUBSCRIPTION, and a MESSAGE where content is published.
• C. A TOPIC with a name unique across the compartment, a SUBSCRIPTION, and a MESSAGE where content is published.
• D. An ALARM with a name unique across the compartment, a SUBSCRIPTION, and a METRIC with the measurement of interest.

Correct answer: B

Explanation

The correct answer is B because it accurately describes the core components required for the Notifications service, including a unique TOPIC, a SUBSCRIPTION, and a MESSAGE for publishing content. Options A and D incorrectly reference ALARMs and METRICS, which are not fundamental to the Notifications service. Option C has the right components but specifies the compartment instead of the tenancy, making it incorrect.
