PAS-C01 Technology Practice Question

This PAS-C01 practice question tests your understanding of technology. 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.

Which TWO are best practices for securing SAP on AWS?

Clue words in this question

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

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

A
Place all SAP systems in the default VPC.
Why wrong: Default VPC is not recommended for production.
B
Attach public IP addresses to all SAP EC2 instances for easy management.
Why wrong: Public IPs expose instances to the internet.
C
Use security groups to control traffic between SAP components.
Security groups are stateful firewalls.
D
Disable security groups and rely on SSH key pairs only.
Why wrong: SSH keys do not replace security groups.
E
Use IAM roles for EC2 instances to access AWS services securely.
Roles avoid hard-coded credentials.

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 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.

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 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.

Detailed technical explanation

How to think about this question

Security groups are stateful, meaning that if you allow inbound traffic on a port, the outbound return traffic is automatically allowed regardless of outbound rules. For SAP, this is particularly important for protocols like RFC (Remote Function Call) which uses dynamic ports in the range 3300–3399 and 4800–4899; security groups can be configured to allow these specific port ranges between the application and database tiers. IAM roles for EC2 instances leverage the AWS STS service to issue temporary credentials via the instance metadata service (IMDSv2), which rotates automatically and eliminates the need to manage static access keys—a common source of credential leakage in SAP environments.

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
