SCS-C02 Identity and Access Management Practice Question
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.
Exhibit
Refer to the exhibit. IAM policy JSON:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::example-bucket/*",
"Condition": {
"IpAddress": {
"aws:SourceIp": "10.0.0.0/16"
}
}
}
]
}
A security engineer attaches this policy to an IAM user. The user tries to download an object from the bucket from an IP address 10.1.0.5. What will happen?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user will be denied access because the condition does not match
Option C is correct because the condition restricts access to IPs in 10.0.0.0/16, and 10.1.0.5 is not in that range. Option A is wrong because the condition is not satisfied. Option B is wrong because there is no explicit deny. Option D is wrong because the policy is valid.
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 user will be denied access because the condition does not match
Why this is correct
The IP is outside the allowed range.
Related concept
Standard ACLs match source addresses.
✗
The user will be allowed access because the policy allows s3:GetObject
Why it's wrong here
The condition is not met, so the allow does not apply.
✗
The policy is invalid and will cause an error
Why it's wrong here
The policy syntax is valid.
✗
The user will be denied access because there is an explicit deny
Why it's wrong here
There is no explicit deny statement.
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.

What is the correct answer to this question?
The correct answer is: The user will be denied access because the condition does not match — Option C is correct because the condition restricts access to IPs in 10.0.0.0/16, and 10.1.0.5 is not in that range. Option A is wrong because the condition is not satisfied. Option B is wrong because there is no explicit deny. Option D is wrong because the policy is valid.
