This question evaluates your knowledge of Amazon EC2 — a core concept tested in AWS Certified Solutions Architect – Professional (SAP-C02). Understanding Amazon EC2 is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
Your application requires high CPU performance for compute-intensive workloads like video encoding. Which Amazon EC2 instance type is optimized for this?
You are migrating a specialized legacy application to AWS that requires a static MAC address for its licensing server. Standard EC2 instances do not guarantee MAC persistence. Which AWS solution provides this capability?
To reduce the cost of a high-throughput, fault-tolerant analytics workload that uses many EC2 instances, you decide to use Spot Instances. How can you ensure the application handles interruptions gracefully?
What is the primary benefit of 'ARM-based' AWS Graviton3 instances over Intel or AMD based instances for modern workloads like microservices?
Your company is running a high-performance computing (HPC) workload that requires extremely low-latency network communication between EC2 instances. Which EC2 feature should you use to ensure instances are physically close to each other in the same availability zone?
