PAS-C01 Operations and Maintenance Practice Question
Which TWO actions should an operations team take to ensure high availability for SAP HANA in a single AWS Region?
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
✓
Deploy SAP HANA in a Multi-AZ configuration using HANA System Replication.
Deploying SAP HANA in a Multi-AZ configuration using HANA System Replication ensures that a replica is maintained in a different Availability Zone, providing high availability across AZs. Option C is correct because HANA System Replication with automatic failover allows the system to automatically fail over to the replica if the primary fails, minimizing downtime. Option A is incorrect because read replicas are used for scaling read operations, not for high availability. Option D is incorrect because automated backups to Amazon S3 provide data protection but do not enable automatic failover. Option E is incorrect because a single EC2 instance in one AZ is a single point of failure and does not provide high availability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create read replicas of the HANA database.
Why it's wrong here
Read replicas are for read scaling, not HA.
- ✓
Deploy SAP HANA in a Multi-AZ configuration using HANA System Replication.
Why this is correct
Multi-AZ with HSR provides failover across Availability Zones.
- ✓
Use HANA System Replication with automatic failover.
Why this is correct
HSR with automatic failover ensures HA.
- ✗
Configure automated backups to Amazon S3.
Why it's wrong here
Backups do not provide automatic failover.
- ✗
Use a single large EC2 instance in one Availability Zone.
Why it's wrong here
Single instance in one AZ is a single point of failure.
