- A
Increase the provisioned IOPS on the EBS volumes attached to the HANA database.
Higher IOPS reduces read latency.
- B
Upgrade the HANA database to a larger instance type with more CPU and memory.
More CPU addresses high utilization.
- C
Add more SAP application servers to the Auto Scaling group.
Increases capacity to handle higher load.
- D
Add a NAT Gateway to the VPC to improve network performance.
Why wrong: NAT Gateway is for outbound internet, not for internal performance.
- E
Deploy a read replica for the HANA database.
Why wrong: Read replicas are for read-heavy workloads, not for reducing disk latency.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An SAP system on AWS is experiencing performance issues during peak hours. The system includes SAP application servers and a HANA database. The CloudWatch metrics show high CPU utilization on the application servers and high disk read latency on the database EBS volumes. Which THREE actions should be taken to improve performance?
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
✓
Increase the provisioned IOPS on the EBS volumes attached to the HANA database.
Option A is correct because increasing provisioned IOPS on the EBS volumes reduces disk read latency, addressing the high disk read latency issue. Option B is correct because upgrading the HANA database to a larger instance type provides more CPU and memory, which helps with high CPU utilization and overall performance. Option C is correct because adding more SAP application servers distributes the load, reducing high CPU utilization on existing servers. Option D is incorrect because a NAT Gateway is for outbound internet traffic and does not improve internal network performance or address CPU/disk latency. Option E is incorrect because a read replica for HANA would not help with disk read latency or CPU utilization; it is typically used for disaster recovery or offloading reporting, not for improving performance of the primary database under high write or read load.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

- ✗
Deploy a read replica for the HANA database.
Why it's wrong here
Read replicas are for read-heavy workloads, not for reducing disk latency.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
