- A
Detach the volume, create a snapshot, create a larger volume from the snapshot, and attach it
Why wrong: Detaching the volume causes downtime.
- B
Create a new larger volume and copy data using rsync
Why wrong: Requires downtime for data copy.
- C
Increase the IOPS of the volume to improve performance
Why wrong: Increasing IOPS does not increase storage capacity.
- D
Use the modify-volume API to increase the size of the existing volume
EBS supports online modification of volume size.

PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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.
An SAP administrator notices that the SAP HANA database is running out of disk space on the /hana/data volume. The volume is an EBS gp3 volume with 2000 GB size. The administrator wants to increase the size without downtime. Which action should be taken?
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 the modify-volume API to increase the size of the existing volume
Option D is correct because AWS EBS gp3 volumes support online resizing via the modify-volume API without requiring downtime. The SAP HANA /hana/data volume can be increased in size while the instance remains running, as EBS volumes can be modified dynamically. After the modification, the administrator must extend the file system to recognize the new space, but no volume detachment or data migration is needed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Detach the volume, create a snapshot, create a larger volume from the snapshot, and attach it
Why it's wrong here
Detaching the volume causes downtime.
- ✗

Requires downtime for data copy.
- ✗
Increase the IOPS of the volume to improve performance
Why it's wrong here
Increasing IOPS does not increase storage capacity.

Use the modify-volume API to increase the size of the existing volume
Why this is correct
EBS supports online modification of volume size.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the need to increase disk space with performance tuning (IOPS) or assume that volume modifications require downtime, leading them to choose snapshot-based or data-copy methods instead of the simpler online resize.
Detailed technical explanation
How to think about this question
EBS gp3 volumes allow modification of size, IOPS, and throughput independently while the volume is attached to a running instance, using the ModifyVolume API. After resizing, the operating system must extend the partition and file system (e.g., using growpart and xfs_growfs for XFS) to utilize the additional space. This capability is critical for SAP HANA, where /hana/data must remain available to avoid database outages, and the modification typically completes in minutes with no performance impact.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
