The answer is that the policy restricts access to the 10.0.0.0/8 IP range, but the user’s office IP of 198.51.100.50 falls outside that range, blocking the upload. This failure occurs because the IAM policy includes a `Condition` block using `aws:SourceIp` to limit S3 actions to a private RFC 1918 address space, while the user’s public IP is external to it. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding of how IAM policy IP address restriction for S3 access works, often appearing as a trap where candidates overlook the explicit IP condition and focus instead on the allowed action or resource. A common mistake is assuming the `s3:PutObject` action alone guarantees access, but the source IP condition overrides it. Remember the mnemonic “IP first, action second”—always check the `Condition` block before the `Action` block when troubleshooting access failures.
SCS-C02 Management and Security Governance Practice Question
This SCS-C02 practice question tests your understanding of management and security governance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 security engineer has attached the above IAM policy to a user. The user reports that they cannot upload objects to the S3 bucket from their office, which has a public IP address of 198.51.100.50. What is the MOST likely reason for the failure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy restricts access to the 10.0.0.0/8 IP range, but the user's IP is outside that range.
Option D is correct because the policy only allows access from the 10.0.0.0/8 IP range, but the user's office IP is 198.51.100.50, which is outside that range. Option A is wrong because the policy allows s3:PutObject. Option B is wrong because the policy applies to the user. Option C is wrong because the bucket is not specified as the resource for the action s3:PutObject, but the resource is the bucket contents (*).
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 policy does not specify the bucket resource for the PutObject action.
Why it's wrong here
The resource is set to the bucket contents.
✗
The policy is not attached to the user.
Why it's wrong here
The policy is attached to the user.
✓
The policy restricts access to the 10.0.0.0/8 IP range, but the user's IP is outside that range.
Why this is correct
The condition requires the source IP to be in 10.0.0.0/8.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

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.
