PAS-C01 Operations and Maintenance Practice Question

This PAS-C01 practice question tests your understanding of operations and maintenance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 SAP HANA on AWS using a multi-node scale-out configuration. During a routine maintenance window, the administrator needs to apply an HANA database software update. What is the BEST practice to minimize downtime?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

A
Perform a rolling update by updating one node at a time while keeping the system operational.
Correct. Rolling updates allow updating nodes individually without taking the entire system offline, minimizing downtime.
B
Use HANA System Replication to fail over to a standby system, then update the primary.
Why wrong: Incorrect. While HSR can be used, it adds complexity and risk; rolling update is simpler and preferred for routine maintenance.
C
Stop all HANA services, apply the update to all nodes, then restart.
Why wrong: Incorrect. Stopping all HANA services causes complete downtime, which is not minimal.
D
Create a new HANA cluster with the updated version and migrate data.
Why wrong: Incorrect. Creating a new cluster and migrating data is time-consuming and unnecessary for a software update.

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

✓

Perform a rolling update by updating one node at a time while keeping the system operational.

Option A is correct because HANA scale-out supports rolling updates, allowing nodes to be updated one by one while the system remains operational, minimizing downtime. Option B is less optimal because using HSR failover adds complexity and is typically reserved for planned migration or disaster recovery, not routine updates. Option C would cause full downtime as it requires stopping all services. Option D is inefficient for a minor software update as it involves creating a new cluster and migrating data.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

What to study next

Got this wrong? Here's your next step.

Identify which PAS-C01 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
