Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Spread placement group
The correct placement group strategies are Cluster placement group (lowest latency, highest throughput), Spread placement group (protects against hardware failures by placing instances on distinct racks), and Partition placement group (reduces likelihood of correlated failures for large distributed and replicated workloads). Option A (Cross-zone load balancing) is a feature of Elastic Load Balancing, not a placement group. Option C (Availability Zone placement group) is not a valid placement group type.
