Quick Answer
The correct method is to use Amazon EFS access points with IAM policies. This approach works because EFS access points enforce root directory and user/group permissions at the filesystem level, while IAM policies can include conditions that restrict access based on the source IP address of the SAP application servers, giving you directory-level control over /sapmnt and /usr/sap/trans. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how to combine EFS access points with IAM authorization for granular access control, a common scenario when securing shared SAP directories. A frequent trap is confusing network-level controls like security groups or NACLs with filesystem-level controls—remember, security groups filter traffic, not directories. Memory tip: think “AP + IAM = IP-aware directory gates” to recall that access points plus IAM source IP conditions lock down specific SAP folders.
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 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?
Configure security group rules to allow only specific IP addresses
Why wrong: Security groups cannot restrict directory access.
Use Amazon S3 bucket policies with IP conditions
Why wrong: S3 is not used for /sapmnt.
Use Amazon EFS access points with IAM policies
Access points enforce directory access, IAM policies can restrict by IP.
Use network ACLs to restrict access by IP
Why wrong: NACLs are network-level, not file-level.
Answer choices
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
Option C is correct because EFS access points with IAM authorization can enforce user/group and root directory permissions, and IAM policies can restrict access based on source IP. Option A is wrong because security group rules apply at the network level, not directory level. Option B is wrong because NACLs are stateless and not directory-aware. Option D is wrong because S3 bucket policies are for S3, not EFS.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
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.
Related concept
Authentication checks who the user is.
Use network ACLs to restrict access by IP
Why it's wrong here
NACLs are network-level, not file-level.
Common exam traps
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
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.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
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
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PAS-C01 questions on access control and AAA configuration.
