PAS-C01 HANA EC2 Best Practices Practice Question

Correct answer & explanation

(Enable CPU hyper-threading) is correct. For SAP HANA, hyper-threading is enabled by default and recommended for production workloads as it improves performance. Option C (Use EBS-optimized instances) is correct because EBS-optimized instances provide dedicated throughput between EC2 and EBS, ensuring consistent storage performance for HANA data and log volumes. Option E (Use placement groups for HANA instances) is correct. Placement groups enable low-latency, high-throughput networking between instances in the same group, which is critical for HANA scale-out or HA setups. Option B (Use burstable instance types (T2/T3)) is incorrect because burstable instances rely on CPU credits and are not designed for sustained high CPU utilization; they are not suitable for production HANA workloads. Option D (Allocate swap space on the instance) is incorrect because SAP HANA relies on in-memory processing and swap space is not recommended; it can degrade performance and is typically disabled.
