The answer is to use EBS-optimized instances and to allocate sufficient memory for the SAP HANA database. EBS-optimized instances provide dedicated network bandwidth specifically for Amazon EBS I/O, preventing contention with other traffic and ensuring consistent, low-latency storage performance critical for HANA’s column-store operations. This directly addresses the need for improved SAP HANA performance on AWS with memory and EBS optimization, as HANA relies heavily on high-throughput, low-latency disk access for data persistence and log writes. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how infrastructure choices map to HANA’s architectural requirements—a common trap is confusing general instance networking with dedicated EBS bandwidth. Remember, HANA lives in memory, so memory sizing is non-negotiable, and EBS optimization is the key to keeping that memory fed without I/O bottlenecks. Memory tip: think “HANA needs RAM and a dedicated lane to its disk.”
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 actions should be taken to improve the performance of an SAP HANA database running on AWS? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the size of the HANA instance to allocate more memory.
Options A and C are correct because they improve I/O and memory respectively. Option B does not directly improve HANA performance. Option D is unrelated to database. Option E is unrelated to performance.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Increase the size of the HANA instance to allocate more memory.
Why this is correct
More memory improves HANA performance.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable termination protection on EC2 instances.
Why it's wrong here
Termination protection prevents accidental deletion, not performance.
✗
Use an Application Load Balancer to distribute traffic.
Use EBS-optimized instances to ensure dedicated network bandwidth for EBS.
Why this is correct
EBS optimization improves I/O performance.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable detailed monitoring on EC2 instances.
Why it's wrong here
Detailed monitoring provides metrics but does not improve performance.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
