PAS-C01 Design of SAP Workloads on AWS Practice Question
Which THREE security best practices should be implemented for SAP systems on AWS? (Choose three.)
⚠ Common exam trap
Many candidates confuse security groups with network ACLs or assume that a single VPC simplifies management, but AWS best practices emphasize isolation and least privilege for SAP workloads, not consolidation.
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 security groups to restrict inbound and outbound traffic to SAP systems.
Security groups act as a virtual firewall for EC2 instances, controlling inbound and outbound traffic at the instance level. For SAP systems, this is critical to restrict access to only necessary ports (e.g., 3200 for SAP Application Server, 36xx for SAProuter, 443 for HTTPS) and trusted IP ranges, reducing the attack surface. Unlike network ACLs, security groups are stateful, meaning return traffic is automatically allowed, simplifying rule management for SAP communication flows.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable SSH key pair access and use only password authentication.
Why it's wrong here
SSH keys are more secure than passwords.
- ✓
Use security groups to restrict inbound and outbound traffic to SAP systems.
Why this is correct
Security groups provide stateful filtering.
- ✗
Deploy all SAP systems in a single VPC for simplified management.
Why it's wrong here
Separate VPCs provide isolation.
- ✓
Use IAM roles for EC2 instances to access AWS services.
Why this is correct
IAM roles are more secure than storing keys.
- ✓
Enable encryption at rest for all EBS volumes used by SAP.
Why this is correct
Encryption protects data at rest.
