Oracle Cloud Infrastructure 2020 Architect Professional — Question 28

You have multiple IAM users who launch different types of compute instances and block volumes every day. As a result, your Oracle Cloud Infrastructure (OCI) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up the environment, you notice that the majority of the instances and block volumes are untagged. Therefore, it is difficult to pinpoint the owner of these resources and verify if they are safe to terminate.
Because of this, your company has issued a new mandate, which requires adding a predefined set of tags to identify owners before launching compute instances.
Which option is the simplest way to implement this new requirement? (Choose the best answer.)

Answer options

• A. Create tag variables to automatically tag a resource with the user name.
• B. Create a policy to automatically tag a resource with the user name.
• C. Create a policy using IAM requiring users to tag specific resources. This will allow a user to launch compute instances only if certain tags were defined.
• D. Create tag variables for each compartment to automatically tag a resource with the user name.
• E. Create a default tag for each compartment, which ensures that appropriate tags are applied at resource creation.

Correct answer: A

Explanation

Option A is correct as it provides a straightforward method to automatically tag resources with the user's name, fulfilling the company's requirement efficiently. Options B and C involve more complex policy management, while D could be more cumbersome due to needing separate variables for each compartment. Option E, while helpful, does not automatically enforce user-specific tagging, which is essential for identifying resource ownership.
