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.
A security engineer is designing a system to manage access to an S3 bucket containing confidential data. Which TWO actions should the engineer take to implement least privilege?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a condition in the IAM policy to restrict access to requests from a specific IP range.
Option A and D are correct. Option A: granting only required actions limits permissions. Option D: using a condition for source IP restricts access to known networks. Option B is wrong because full access is not least privilege. Option C is wrong because pre-signed URLs are for temporary access, not for ongoing least privilege. Option E is wrong because public access is the opposite.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use a condition in the IAM policy to restrict access to requests from a specific IP range.
Why this is correct
Restricting by IP reduces the attack surface.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✓
Grant only the specific S3 actions needed (e.g., s3:GetObject) rather than s3:*
Why this is correct
Granting specific actions follows least privilege.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
Use a policy that allows s3:* for all users in the organization.
Why it's wrong here
This grants full access, not least privilege.
✗
Make the bucket public and rely on object ACLs to restrict access.
Why it's wrong here
Public bucket is not secure.
✗
Use pre-signed URLs for all access to the bucket.
Why it's wrong here
Pre-signed URLs are for temporary access, not for ongoing least privilege.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related SCS-C02 questions on access control and AAA configuration.

What is the correct answer to this question?
The correct answer is: Use a condition in the IAM policy to restrict access to requests from a specific IP range. — Option A and D are correct. Option A: granting only required actions limits permissions. Option D: using a condition for source IP restricts access to known networks. Option B is wrong because full access is not least privilege. Option C is wrong because pre-signed URLs are for temporary access, not for ongoing least privilege. Option E is wrong because public access is the opposite.

Are there clue words in this question I should notice?
Yes — watch for: "least". You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
