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
✓
DiskReadOps
CPUUtilization, Memory (via custom metrics or CloudWatch agent), and DiskReadOps/DiskWriteOps are key performance indicators. NetworkIn/NetworkOut are important for network throughput but not directly for database resource constraints. DatabaseConnections is for RDS, not EC2-hosted HANA.
