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
✓
x1e.32xlarge with EBS io1 volumes
The x1e.32xlarge instance is SAP HANA certified and provides the required memory for large HANA databases. EBS io1 volumes deliver the high IOPS needed for the 10 TB database. Option B (r5.24xlarge with io1) is incorrect because r5 instances are not HANA optimized. Option C (x1e.32xlarge with instance store) is incorrect because instance store is ephemeral and not suitable for persistent data. Option D (r5.24xlarge with gp2) is incorrect because gp2 cannot achieve the high IOPS required for this workload.
