SCS-C02 Management and Security Governance Practice Question

This SCS-C02 practice question tests your understanding of management and security governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Exhibit

    }
  ]
}

Refer to the exhibit. An IAM policy is attached to a user. The user attempts to upload an object to my-bucket using server-side encryption with AWS KMS (SSE-KMS). What is the outcome?

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 upload fails because the Deny statement denies any PutObject that does not use AES256 encryption.

Option D is correct because the Deny statement applies when encryption is not AES256, and SSE-KMS is not AES256. The Allow statement allows only AES256. Since SSE-KMS does not match, the Deny overrides. Option A is wrong because the Deny statement denies. Option B is wrong because the Allow only allows AES256. Option C is wrong because the Deny is explicit.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

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 upload fails because the Deny statement denies any PutObject that does not use AES256 encryption.

    Why this is correct

    The Deny statement explicitly denies when encryption is not AES256.

    Related concept

    Standard ACLs match source addresses.

  • ✗

    The upload fails because the Allow statement requires AES256 encryption.

    Why it's wrong here

    The Allow statement does not deny; it just doesn't grant permission. An explicit Deny also applies.

  • ✗

    The upload succeeds because the policy does not explicitly deny SSE-KMS.

    Why it's wrong here

    The Deny statement denies any PutObject that is not AES256.

  • ✗

    The upload succeeds because the Allow statement matches the s3:PutObject action.

    Why it's wrong here

    The Allow only matches if encryption is AES256, which it is not.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

  • Standard ACLs match source addresses.
  • Extended ACLs can match source, destination, protocol and ports.
  • The first matching ACL entry is used.
  • There is usually an implicit deny at the end.

TExam Day Tips

  • Check inbound versus outbound direction.
  • Read the ACL from top to bottom.
  • Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

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.

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SCS-C02 ACL questions on filtering logic and placement.
