AWS Certified Solutions Architect Professional SAP-C02 Practice Question

An investment bank runs a latency-sensitive pricing engine on Amazon EC2. The engine's nodes are placed in an EFA-enabled cluster placement group. Benchmarks show the code is CPU-bound, requires a sustained all-core turbo frequency above 3.5 GHz, and needs at least 300 Gbps of Elastic Fabric Adapter bandwidth to keep inter-node latency within the service-level objective. The software is licensed per core and depends on x86 AVX-512 instructions, so the team wants to maximize performance per licensed core while keeping costs low. Which EC2 instance family should the solutions architect select to meet these requirements with the best price/performance?

  • Amazon EC2 Hpc7g instances powered by AWS Graviton3E processors

  • Amazon EC2 C7i instances powered by custom 4th Gen Intel Xeon Scalable processors

  • Amazon EC2 Hpc6id instances with local NVMe storage and 3rd Gen Intel Xeon processors

  • Amazon EC2 Hpc7a instances powered by 4th Gen AMD EPYC processors
