Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The KMS key ARN is malformed; it contains extra characters.

The S3 action is allowed on objects only (arn:aws:s3:::sap-backup-bucket/*) but not on the bucket itself. For PutObject, the resource must be the object ARN, which is correct. However, the policy also requires kms:Decrypt for the KMS key, but the key ARN is wrong (it has extra characters). Option B is correct. Option A is wrong because the action is allowed. Option C is wrong because ec2:Describe* is not needed. Option D is wrong because the bucket policy is not shown.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The resource for S3 should include the bucket itself (arn:aws:s3:::sap-backup-bucket).

    Why it's wrong here

    PutObject requires object ARN, which is correct.

  • The ec2:Describe* action is not required and causes a conflict.

    Why it's wrong here

    Unused actions do not cause failures.

  • The s3:* action is too broad and is denied by an S3 bucket policy.

    Why it's wrong here

    The action is allowed, bucket policy might override but not necessarily.

  • The KMS key ARN is malformed; it contains extra characters.

    Why this is correct

    The key ARN has a typo with 'a123b4cd56ef' instead of proper format.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
