The answer is cluster quorum loss due to insufficient votes, and the fix is to add a third node or configure a witness. In a two-node SAP ASCS and PAS cluster on SUSE Linux Enterprise Server, each node holds one vote; if one node fails or loses heartbeat connectivity, the remaining node lacks a majority, causing the cluster to panic and fail over unnecessarily. This scenario tests your understanding of SAP cluster quorum failover mechanics on the AWS Certified SAP on AWS Specialty PAS-C01 exam, where the common trap is misdiagnosing the root cause as memory pressure, network latency, or disk I/O—none of which trigger repeated failovers by themselves. Remember the memory tip: “Two nodes, one vote each, no tiebreaker—expect a flip-flop.” Always verify the cluster’s expected votes against the total votes to spot quorum loss as the hidden culprit behind frequent, unexplained failovers.
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 SAP S/4HANA on AWS using an ASCS and PAS cluster with SUSE Linux Enterprise Server. The cluster fails over unexpectedly several times a day. What is the most likely cause and solution?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cluster quorum loss due to insufficient votes; add a third node or configure a witness
Option D is correct because cluster quorum loss causes unnecessary failovers, and adding a third node resolves it. Option A is wrong as memory is not a typical cause. Option B is wrong because network latency wouldn't cause frequent failovers. Option C is wrong because disk I/O doesn't cause failovers.
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.
✗
High network latency between nodes; use placement groups
Why it's wrong here
Latency might cause timeouts but not multiple daily failovers.
✓
Cluster quorum loss due to insufficient votes; add a third node or configure a witness
Why this is correct
Quorum loss triggers failover; adding a node stabilizes the cluster.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Insufficient memory on the cluster nodes; increase memory
Why it's wrong here
Memory shortage doesn't cause failovers.
✗
Incorrect ASCS instance configuration; verify SAP profiles
Why it's wrong here
ASCS config error wouldn't cause cluster failovers.
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 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.
