The answer is a network connection failure between the ABAP application server and HANA. The log entry showing an SAP ABAP HANA RFC communication failure directly indicates that the Remote Function Call between the two systems could not establish a session, which is almost always caused by a broken network path rather than a database crash or authentication issue. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your ability to distinguish between infrastructure-level connectivity problems and application-level errors, a common trap where candidates mistakenly blame the HANA database or the ABAP program itself. Remember that RFC failures are network-layer events; if the log does not mention login errors or dump codes, focus on connectivity. Memory tip: RFC = Really Focus on Connectivity.
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.
Exhibit
Refer to the exhibit.
CloudWatch Logs log entry:
```
2023-10-01T12:00:00Z [ABAP] System: PRD, Program: Z_MONITOR, Error: RFC communication failure with destination SAPDBHOST (HANA)
```
Refer to the exhibit. An operations team sees this log entry in CloudWatch Logs for an SAP system. What is the MOST likely cause?
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
✓
The network connection between the ABAP application server and HANA is down.
Option B is correct. The error indicates an RFC communication failure, which is typically due to a network issue. Option A is wrong because there is no indication of HANA crash. Option C is wrong because the error is about communication, not authentication. Option D is wrong because the error is not about the ABAP program itself.
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.
✗
The HANA database has crashed.
Why it's wrong here
The error is about RFC communication, not a database crash.
✗
The SAP system user password has expired.
Why it's wrong here
Password expiry would cause authentication errors, not RFC communication failure.
✓
The network connection between the ABAP application server and HANA is down.
Why this is correct
RFC communication failure typically indicates a network issue.
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.
✗
The ABAP program Z_MONITOR has a bug.
Why it's wrong here
The error is not about the program logic.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
