PAS-C01 Operations and Maintenance Practice Question
A company runs SAP HANA on AWS using EC2 instances with HANA data replication between two Availability Zones. The operations team needs to test a disaster recovery failover. What is the correct procedure to promote the secondary HANA system to primary?
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
✓
Use the HANA takeover command on the secondary system
For HANA system replication, the secondary must be taken over using HANA Studio or hdbsql. Stopping the primary or shutting down EC2 instances does not trigger a clean takeover; modifying DNS without promoting the database would cause data inconsistency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Stop the primary HANA system on the primary EC2 instance
Why it's wrong here
Stopping the primary alone does not promote the secondary; you must initiate a takeover on the secondary.
- ✓
Use the HANA takeover command on the secondary system
Why this is correct
The takeover command promotes the secondary to primary.
- ✗
Modify the DNS record to point to the secondary instance
Why it's wrong here
Modifying DNS without promoting the database leads to inconsistency.
- ✗
Shut down the primary EC2 instance and wait for automatic failover
Why it's wrong here
Automatic failover requires proper configuration and typically a manual takeover is recommended for testing.
