The correct answer is to generate a presigned URL for each file the auditor needs to download, as this method provides secure temporary S3 access to an external auditor without exposing the bucket or managing long-term credentials. A presigned URL embeds temporary permissions scoped to a single object, with an expiration time you control, ensuring the auditor can only download specific SAP backup files for a limited window. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of secure delegation patterns for third-party access, often appearing as a trap where candidates mistakenly consider creating an IAM user or sharing root keys. The key distinction is that presigned URLs eliminate credential management and enforce the principle of least privilege by tying access to a specific action and object. Memory tip: think “URL, not user” — presigned URLs grant time-boxed object access, while IAM users create permanent security risks.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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.
An SAP administrator needs to provide temporary, time-limited access to an S3 bucket containing SAP backup files for an external auditor. The auditor should be able to download files from the bucket. Which method provides the most secure way to grant access?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Generate a presigned URL for each file the auditor needs to download.
Option C is correct: Generate a presigned URL that provides temporary access to a specific object. It is secure because permissions are time-limited and scoped to a single object. Option A is wrong: Creating an IAM user for the auditor is not time-limited and requires managing credentials. Option B is wrong: Making the bucket public is insecure. Option D is wrong: Sharing AWS credentials is a security risk.
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.
✗
Create an IAM user with read-only access to the bucket and share the credentials with the auditor.
Why it's wrong here
Credentials are long-lived and not temporary.
✗
Provide the auditor with the root user credentials of the AWS account.
Why it's wrong here
Sharing root credentials is a severe security risk.
✗
Make the bucket publicly readable and share the bucket URL.
Why it's wrong here
Public access is insecure and not time-limited.
✓
Generate a presigned URL for each file the auditor needs to download.
Why this is correct
Presigned URLs are time-limited and scoped to specific objects.

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.
