Master SQS, EC2 Auto Scaling, AWS Transfer Family, Amazon DynamoDB, DynamoDB Accelerator (DAX)

Preparing for the AWS Certified Solutions Architect - Professional (SAP-C02) exam? Passing this pro-level exam isn't about memorizing features; it’s about becoming an architectural detective who knows how to spot critical constraints and keywords under pressure.

In this video, we break down core pro-level exam scenarios across scalability, high availability, disaster recovery, and security. Learn how to identify exactly what AWS services to choose based on phrases like "least operational overhead," "no data loss," or "lowest possible latency."

Here is a breakdown of the specific AWS services, features, and troubleshooting scenarios covered in this guide:

🔹 [00:01:13] Amazon SQS & EC2 Auto Scaling: Troubleshooting why messages end up in a Dead Letter Queue (DLQ) even when visibility timeouts look correct. Learn how to apply Auto Scaling Scale-In Protection to prevent EC2 instances from terminating mid-job.
🔹 [00:02:19] AWS Transfer Family & Amazon S3: How to modernize legacy file transfers without modifying client devices or using the S3 API directly.
🔹 [00:03:15] Amazon DynamoDB & DynamoDB Accelerator (DAX): Moving from millisecond to microsecond read latency for trading platforms and ultra-latency-sensitive workloads.
🔹 [00:03:54] Amazon Aurora Global Database: Achieving a Recovery Point Objective (RPO) of zero for multi-region disaster recovery setups with synchronous replication.
🔹 [00:04:56] AWS Database Migration Service (DMS) & EC2: Architecting a low-cost, high-efficiency "Pilot Light" disaster recovery strategy for hybrid-cloud deployments.
🔹 [00:05:32] AWS Identity and Access Management (IAM): The secure, best-practice approach to setting up temporary, read-only external access using Cross-Account IAM Roles and trust relationships instead of creating permanent IAM users.

💡 Core Exam Principles to Remember:
1. Always hunt down the exact keywords and constraints.
2. Lean toward fully managed services to reduce operational overhead.
3. Decouple your components for resilience and scalability.
4. Understand the hard boundary between RPO (data loss) and RTO (recovery time).
5. Use IAM Cross-Account Roles for external third-party access.
