PAS-C01 Operations and Maintenance Practice Question
A company runs a critical SAP S/4HANA system on AWS. The system uses an SAP HANA database on an EC2 instance with EBS storage. The operations team receives an alert that the database is running out of disk space on the /hana/data volume. The current configuration uses a single 2 TB gp2 EBS volume for /hana/data, which is 85% full. The team needs to resolve the immediate space issue and also plan for future growth. The database is in production and cannot tolerate downtime. The team has enabled Multi-Attach on the volume. Which course of action should the team take?
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
✓
Attach an additional EBS volume, create a logical volume spanning both volumes, and extend the filesystem without downtime.
It allows adding a second EBS volume to the instance and creating a logical volume spanning both volumes, then extending the filesystem online without downtime. This is a common approach for increasing space on SAP HANA data volumes without downtime. Option A is incorrect because Amazon EFS has higher latency and is not suitable for SAP HANA database data, which requires high throughput and low latency. Option B is incorrect because although Elastic Volumes allows resizing online, the existing volume is gp2 and resizing to 4 TB is possible, but the question emphasizes planning for future growth, and adding another volume provides more flexibility. Option D is incorrect because taking an EBS snapshot requires quiescing the database, which would incur downtime.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Migrate the data to Amazon EFS and mount it to the EC2 instance.
Why it's wrong here
Migrating data to Amazon EFS is not suitable because EFS has higher latency and lower throughput compared to EBS, which would negatively impact SAP HANA performance.
- ✗
Use the Elastic Volumes feature to modify the size of the existing volume to 4 TB while the instance is running.
Why it's wrong here
Using Elastic Volumes to resize the existing gp2 volume to 4 TB online can cause a brief performance degradation and may not be advisable for a critical production database without downtime.
- ✓
Attach an additional EBS volume, create a logical volume spanning both volumes, and extend the filesystem without downtime.
Why this is correct
Attaching an additional EBS volume and using LVM to extend the filesystem online allows for capacity increase without any downtime, making it the best choice.
- ✗
Take an EBS snapshot of the volume, create a larger volume from the snapshot, and attach it to the instance.
Why it's wrong here
Taking an EBS snapshot requires I/O freeze for consistency, which would cause downtime, so this is not suitable for a production system that cannot tolerate downtime.
