SAP HANA Not Responding Despite EC2 Running: Check Service Status
This PAS-C01 practice question tests your understanding of technology. 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.
Network Topology
An SAP administrator runs the AWS CLI command shown in the exhibit to check the status of a production HANA instance. The output shows the instance is running in us-east-1a. However, the SAP application team reports that the HANA database is not responding. What should the administrator check next to diagnose the issue?
Network Topology
A
The EBS volumes are detached from the instance
Why wrong: No indication of volume detachment; the instance is running.
B
The instance state is 'running' so no issue with the instance
Why wrong: The instance can be running but the database may be down.
C
The HANA database service is not running on the instance
The administrator should verify the HANA process is running.
D
The security group does not allow inbound traffic to the database port
Why wrong: The command does not check security group rules.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The HANA database service is not running on the instance
The AWS CLI command only checks the EC2 instance state (e.g., 'running'), not the status of the HANA database service itself. Even if the instance is running, the HANA database service (hdbnameserver, hdbindexserver, etc.) may have crashed, failed to start, or been stopped. The administrator should SSH into the instance and run commands like 'systemctl status hdbindexserver' or 'sapcontrol -nr <instance_number> -function GetProcessList' to verify the HANA service status.
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
The trap here is that candidates assume an EC2 instance state of 'running' guarantees all applications on it are functional, but AWS separates infrastructure health from guest OS/application health, and the exam tests this distinction by requiring you to check the database service separately.

Command / output trap
The command does not check security group rules.
Detailed technical explanation
How to think about this question
SAP HANA runs as a set of systemd services (e.g., sapinit, hdbdaemon) and processes managed by the SAP Host Agent. The 'aws ec2 describe-instances' command returns the instance lifecycle state (pending, running, stopping, stopped), which is independent of guest OS or application health. A common real-world scenario is a HANA crash due to memory pressure or kernel panic, leaving the EC2 instance running but the database unresponsive; administrators must use SAP-specific tools like 'sapcontrol' or 'hdbsql' to diagnose the service layer.
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.
TExam Day Tips
→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.
