PAS-C01 Design of SAP Workloads on AWS Practice Question
A company runs SAP on AWS and uses a shared Amazon EFS file system for /sapmnt and /usr/sap/trans. The administrator wants to control access to specific directories based on the source IP address of the SAP application servers. Which method should be used to achieve this?
⚠ Common exam trap
Candidates often confuse network-level controls (security groups, NACLs) with file-system-level controls, assuming IP-based restrictions can be applied directly to directories within a shared EFS volume, when in fact EFS access points with IAM policies are the correct AWS-native mechanism for this granularity.
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
✓
Use Amazon EFS access points with IAM policies
Amazon EFS access points can be combined with IAM policies to enforce a specific POSIX user and directory path per application, and IAM conditions can restrict access based on the source IP address of the SAP application servers. This allows fine-grained control over which EC2 instances (by IP) can access specific subdirectories like /sapmnt or /usr/sap/trans without modifying the NFS client configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure security group rules to allow only specific IP addresses
Why it's wrong here
Security groups cannot restrict directory access.
- ✗
Use Amazon S3 bucket policies with IP conditions
Why it's wrong here
S3 is not used for /sapmnt.
- ✓
Use Amazon EFS access points with IAM policies
Why this is correct
Access points enforce directory access, IAM policies can restrict by IP.
- ✗
Use network ACLs to restrict access by IP
Why it's wrong here
NACLs are network-level, not file-level.
