Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 52

Multiple teams are sharing a tenancy in Oracle Cloud Infrastructure (OCI). You are asked to figure out an appropriate method to manage OCI costs.
Which is NOT a valid technique to accurately attribute costs to resources used by each team? (Choose the best answer.)

Answer options

• A. Create a Cost-Tracking tag. Apply this tag to all resources with team information. Use the OCI cost analysis tools to filter costs by tags.
• B. Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.
• C. Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.
• D. Define and use tags for resources used by each team. Analyze usage data from the OCI Usage Report which has detailed information about resources and tags.

Correct answer: C

Explanation

The correct answer is C because creating IAM groups and budgets does not directly attribute costs to resources; it merely manages access and budget tracking. In contrast, options A, B, and D all involve tagging or compartmentalizing resources, which are effective methods for tracking costs associated with specific teams in OCI.
