- A
Check SAP application logs for errors, then check HANA database status using HDBSQL, then verify network connectivity using ping and telnet, then verify security group and NACL rules, then verify authentication credentials.
This is the correct order because it follows a logical troubleshooting methodology: start with application logs to identify the error, then verify the database is running, check network connectivity, review firewall rules, and finally confirm authentication credentials.
- B
Check HANA database status using HDBSQL, then check SAP application logs for errors, then verify network connectivity using ping and telnet, then verify authentication credentials, then verify security group and NACL rules.
Why wrong: This is incorrect because checking the database status before reviewing application logs may miss errors that indicate the specific failure reason. Also, verifying authentication before security groups is out of order; security rules should be confirmed before assuming credentials are the issue.
- C
Verify network connectivity using ping and telnet, then verify security group and NACL rules, then check SAP application logs for errors, then check HANA database status using HDBSQL, then verify authentication credentials.
Why wrong: This is incorrect because starting with network checks bypasses the application logs, which often contain the exact error message needed to diagnose the problem. Logs should be the first step to provide context for subsequent checks.
- D
Verify authentication credentials, then check SAP application logs for errors, then check HANA database status using HDBSQL, then verify network connectivity using ping and telnet, then verify security group and NACL rules.
Why wrong: This is incorrect because it assumes authentication is the problem without first verifying the database and network. Logs should be consulted early, and credentials should be checked only after confirming that the database is reachable and security groups allow traffic.
SAP HANA Connection Failure Troubleshooting Steps
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.
Drag and drop the steps to troubleshoot an SAP HANA database connection failure from an SAP application in AWS into the correct order.
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
Check SAP application logs for errors, then check HANA database status using HDBSQL, then verify network connectivity using ping and telnet, then verify security group and NACL rules, then verify authentication credentials.
Troubleshooting should start with logs, then check database status, network, security groups, and authentication.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

- ✓
Check SAP application logs for errors, then check HANA database status using HDBSQL, then verify network connectivity using ping and telnet, then verify security group and NACL rules, then verify authentication credentials.
Why this is correct
This is the correct order because it follows a logical troubleshooting methodology: start with application logs to identify the error, then verify the database is running, check network connectivity, review firewall rules, and finally confirm authentication credentials.
Related concept
Standard ACLs match source addresses.
- ✗
Check HANA database status using HDBSQL, then check SAP application logs for errors, then verify network connectivity using ping and telnet, then verify authentication credentials, then verify security group and NACL rules.
Why it's wrong here
This is incorrect because checking the database status before reviewing application logs may miss errors that indicate the specific failure reason. Also, verifying authentication before security groups is out of order; security rules should be confirmed before assuming credentials are the issue.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PAS-C01 ACL questions on filtering logic and placement.
