AWS Certified Solutions Architect - Professional

SAP questions read like short stories. The scenario is 4-8 sentences with embedded constraints (compliance, RTO, latency, budget) and the answer is the option that satisfies all of them. Read the final question stem first, then the scenario - it tells you what to optimize for and which constraints to ignore.

Multiple options will technically work. The right answer is the one with the lowest operational overhead while meeting every stated requirement. 'Use a Lambda function and EventBridge' beats 'Run a cron job on EC2' nine times out of ten - if both meet the requirements, choose managed.

Multi-account architecture is the largest single theme. Master AWS Organizations (OUs, SCPs, account vending), Control Tower (preventive vs detective guardrails), IAM Identity Center (permission sets, delegated admin), and the security/log archive/audit account pattern. Many questions hinge on 'which account does X belong in'.

Hybrid networking is the highest-leverage study topic. Know Transit Gateway attachments (VPC, VPN, DX Gateway, peering), Direct Connect resilience tiers (single, high, maximum), Cloud WAN vs TGW, PrivateLink vs VPC peering, and how Route 53 Resolver endpoints bridge on-prem DNS with VPC DNS. Draw the diagrams until the patterns are muscle memory.

Migration questions test the 7 R's by name. Memorize which AWS service is the canonical answer for each: MGN (Rehost), DMS + SCT (Database), DataSync (File), App2Container (Replatform to containers), AWS Migration Hub (orchestration), Snow family (offline at scale). 'Refactor' often means re-architecting for serverless or containers - those questions surface here, not in the deployment domain.

Disaster recovery questions almost always include explicit RTO/RPO numbers. Map them to the four strategies: Backup & Restore (hours-to-days RTO), Pilot Light (tens of minutes), Warm Standby (minutes), Multi-site Active-Active (seconds, near-zero RPO). Aurora Global Database, DynamoDB Global Tables, and Route 53 failover are the building blocks for the higher tiers.

Cost optimization at SAP scale is more than RIs. Expect Savings Plans (Compute vs EC2 Instance, 1-year vs 3-year, payment options), Compute Optimizer right-sizing recommendations, Cost Allocation Tags for chargeback, Cost Anomaly Detection, AWS Budgets actions, and Trusted Advisor checks. Consolidated billing volume discounts and shared RI/SP coverage across the org are common distractors.

Database questions often hide the right answer in the access pattern, not the data shape. Single-digit-millisecond key-value at any scale → DynamoDB. Complex joins or transactions → Aurora. Heterogeneous source-to-target migration → DMS + SCT. Online cutover with minimal downtime → DMS with CDC. The vendor-specific source DB (Oracle, SQL Server) usually maps to Aurora PostgreSQL or MySQL via SCT.

Watch for keyword traps in the stem: 'most cost-effective' weighs cost over performance, 'least operational overhead' favors managed/serverless, 'highest availability' implies multi-AZ minimum (often multi-region), 'real-time' means streaming (Kinesis/MSK) not batch, 'eventually consistent is acceptable' opens the door to S3, DynamoDB defaults, and async replication.

Time budget: 75 questions in 180 minutes is 2.4 min average, but multi-response questions and long scenarios run 4-5 min. Sweep the exam in two passes - answer everything you're sure about, flag the long ones, return after the quick wins are banked. The 10 unscored questions are sprinkled in; you cannot identify them, so answer every question.
