PAS-C01 Design of SAP Workloads on AWS Practice Question

This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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.

An SAP system is running on an EC2 instance with an instance profile that grants access to an S3 bucket. The application is unable to read a specific object from the bucket. What is the first step to troubleshoot the issue?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

A
Check the security group associated with the instance
Why wrong: Security groups do not control access to S3.
B
Check the network ACLs
Why wrong: NACLs are for VPC subnet traffic, not S3 access.
C
Check the IAM policy attached to the instance profile
The instance profile's IAM role must have s3:GetObject permission for the object.
D
Check the S3 bucket policy
Why wrong: Bucket policy might be blocking access, but first step is to check IAM permissions.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Check the IAM policy attached to the instance profile

The instance profile grants the EC2 instance permissions to access the S3 bucket via IAM roles. If the application cannot read a specific object, the most likely cause is that the IAM policy attached to the instance profile does not include the necessary permissions (e.g., s3:GetObject) for that object. Checking the IAM policy is the first logical step because it directly controls the identity-based access for the instance.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often jump to checking the S3 bucket policy first, forgetting that the instance profile's IAM policy is the primary gatekeeper for EC2-based access, and bucket policies only come into play if the IAM policy allows the action.

Detailed technical explanation

How to think about this question

When an EC2 instance assumes an IAM role via an instance profile, the AWS SDK automatically retrieves temporary credentials from the instance metadata service (IMDS). These credentials are then used to sign API requests to S3. If the IAM policy lacks the s3:GetObject action for the specific object ARN (or uses a condition key like s3:ResourceAccount that mismatches), the request will fail with an AccessDenied error. In contrast, bucket policies are evaluated after IAM policies, so a missing IAM permission will block access regardless of the bucket policy.

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.

TExam Day Tips

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.

Quick reference

AWS S3 Storage Class Comparison

Storage Class	Min Duration	Retrieval	Use Case
S3 Standard	None	Immediate	Frequently accessed data
S3 Standard-IA	30 days	Immediate	Infrequent access, rapid retrieval
S3 One Zone-IA	30 days	Immediate	Non-critical infrequent data
S3 Intelligent-Tiering	None	Immediate–hours	Unknown or changing access patterns
S3 Glacier Instant	90 days	Milliseconds	Archive with instant retrieval
S3 Glacier Flexible	90 days	Minutes–hours	Archive, flexible retrieval
S3 Glacier Deep Archive	180 days	Hours	Long-term compliance archive
