PAS-C01 Technology Practice Question
Which TWO are best practices for securing SAP on AWS?
⚠ Common exam trap
Test-takers frequently assume that because SAP systems are business-critical, they should be placed in the default VPC for simplicity, or that public IPs are needed for management access, when in fact AWS best practices mandate private subnets, bastion hosts, and IAM roles to maintain security and compliance.

Correct answer & explanation
✓
Use security groups to control traffic between SAP components.
Security groups act as a virtual firewall for EC2 instances, allowing you to control inbound and outbound traffic at the instance level. For SAP on AWS, using security groups to restrict traffic between SAP components (e.g., between the SAP application server and database server) is a best practice because it enforces least-privilege access and reduces the attack surface. IAM roles for EC2 instances enable secure, automated access to AWS services (like S3 for backups or CloudWatch for monitoring) without embedding long-term credentials in the instance, which is critical for compliance and operational security.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place all SAP systems in the default VPC.
Why it's wrong here
Default VPC is not recommended for production.
- ✗
Attach public IP addresses to all SAP EC2 instances for easy management.
Why it's wrong here
Public IPs expose instances to the internet.
- ✓
Use security groups to control traffic between SAP components.
Why this is correct
Security groups are stateful firewalls.
- ✗
Disable security groups and rely on SSH key pairs only.
Why it's wrong here
SSH keys do not replace security groups.
- ✓
Use IAM roles for EC2 instances to access AWS services securely.
Why this is correct
Roles avoid hard-coded credentials.
