Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Apply tags to resources only after creation to avoid governance issues.
Why it's wrong here
Tags should be applied at creation and enforced with policies; retroactive tagging can be inconsistent.
- ✓
Define a set of mandatory tag keys such as CostCenter, Project, and Environment with standardized values.
Why this is correct
Mandatory tags with controlled values ensure consistent cost attribution across all resources.
- ✗
Use a single tag key 'Environment' with values 'Production' or 'Development'.
Why it's wrong here
While Environment is useful, it does not capture department or project information for cost attribution.
- ✗
Use free-form text for tag values to allow flexibility.
Why it's wrong here
Free-form values lead to inconsistencies and make reporting difficult.
