Episode 35: AWS SAA-C03 Compute & Containers - Revision + 13 Exam Questions | TechTalkWithBalu

🎁 Free SAA-C03 cheat sheet for this series - link at the bottom.

Topic challenge #5, segmented format! Quick revision, then 13 compute questions split into 3 themed blocks - so it flows like a guided session, not a question dump.

🆕 THE FORMAT

🧠 Tight intro (no long front-loaded lecture)

📦 3 themed blocks with teaching beats between them:

1️⃣ EC2 Fundamentals (instances & placement)

2️⃣ Scaling & Cost (Auto Scaling & purchasing)

3️⃣ Serverless & Containers (Lambda, ECS/EKS/Fargate)

⏱️ A pause after each question to lock in YOUR answer

✅ The answer + WHY it's right

❌ WHY each wrong option is wrong

Because on the real exam, eliminating the plausible-but-wrong options is the whole game.

🎯 THE PAYOFF

By the end you'll have the 4 compute decisions the exam leans on most locked in - the ones that quietly decide a handful of marks on test day.

📋 THE 13 QUESTIONS TEST

BLOCK 1 - EC2 Fundamentals:

• Cluster placement group (lowest-latency HPC)

• Memory-optimized instances (in-memory cache)

• On-Demand Capacity Reservations (guaranteed AZ capacity)

• Accelerated computing (GPU for ML)

BLOCK 2 - Scaling & Cost:

• Scheduled scaling (predictable daily peak)

• Reserved/Savings Plans (steady 3-year workload)

• Spot Instances (interruptible batch)

• Target tracking scaling (hold CPU at 50%)

• Mixed instances policy (blend On-Demand + Spot)

BLOCK 3 - Serverless & Containers:

• Fargate (containers, no instance management)

• Lambda (event-driven function)

• EKS (when you specifically need Kubernetes)

• ECR (Docker image registry)

💡 THE 4 COMPUTE DECISIONS DRILLED

1. Instance family: match the bottleneck (memory/compute/GPU)

2. Purchasing: On-Demand / Reserved / Spot / Capacity Reservation

3. Scaling: scheduled (clock) vs target tracking (metric) vs mixed

4. Compute model: Lambda / Fargate / ECS / EKS / ECR

Spot which group the question is testing, and the answer falls out.

🎓 SCORING
