Quick Answer
The answer is the Resource element. In an IAM policy, the Resource element is the correct choice to restrict access to a specific S3 bucket because it defines the Amazon Resource Name (ARN) of the bucket, such as arn:aws:s3:::example-bucket, thereby limiting the policy’s effect to that exact resource. While the Principal element specifies who can access it, the Action element defines what operations are allowed, and the Condition element sets when the policy applies, only the Resource element pinpoints which bucket is being targeted. On the AWS Certified Security Specialty SCS-C02 exam, this concept tests your understanding of how IAM policy structure maps to least privilege—a common trap is confusing Resource with Principal, but remember that Principal is about identity, not the bucket itself. A helpful memory tip: think of the Resource element as the “address” of the bucket, while Action is the “key” and Condition is the “time of day.”
This SCS-C02 practice question tests your understanding of identity and access management. 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.
A developer needs to grant an IAM user access to a specific S3 bucket only. Which IAM policy element should be used to restrict access to that bucket?
Principal
Why wrong: Principal identifies the entity allowed access.
Condition
Why wrong: Condition adds constraints to the policy.
Resource
Resource specifies the bucket ARN.
Action
Why wrong: Action specifies allowed API calls.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Resource
Option C is correct because the Resource element specifies the ARN of the S3 bucket. Option A is wrong because Principal specifies who gets access, not the resource. Option B is wrong because Action specifies allowed actions. Option D is wrong because Condition specifies when the policy applies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Principal
Why it's wrong here
Principal identifies the entity allowed access.
Condition
Why it's wrong here
Condition adds constraints to the policy.
Resource
Why this is correct
Resource specifies the bucket ARN.

Action
Why it's wrong here
Action specifies allowed API calls.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
