PAS-C01 Operations and Maintenance Practice Question

This PAS-C01 practice question tests your understanding of operations and maintenance. 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.

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.

Option C is correct because 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.

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.

  • 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.

    Related concept

    Read the scenario before looking for a memorised answer.

  • 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.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.
