Episode 10.5: Exam Q&A - 35 Rapid-Fire Questions: ASG, S3, Storage, Databases & Route 53 | SAA-C03

Test your knowledge! 35 rapid-fire questions covering Episodes 6-10: Auto Scaling Groups, S3, Storage Architectures, Databases & Route 53.

⚡ HOW THIS WORKS

ACTIVE RECALL FORMAT:

- I ask a question

- 5-second pause for you to think

- I give the answer + explanation

- Track your score (1 point per correct answer)

This is ACTIVE RECALL - the most effective study method. Testing yourself is 2-3x more effective than passive review!

📋 QUESTION BREAKDOWN

AUTO SCALING GROUPS (7 Questions):

- ASG capacity constraints (min/desired/max)

- Scaling policies (Target Tracking vs Scheduled)

- EC2 vs ELB health checks

- Lifecycle hooks

- Termination policies

- Predictable vs unpredictable scaling

Sample: "ASG has min 2, desired 6, max 10. You terminate 3 instances. What happens?"

AMAZON S3 (7 Questions):

- Storage classes & costs (Glacier Deep Archive $1/TB!)

- Minimum storage durations (Standard-IA 30 days)

- Versioning (only new objects after enabling)

- Cross-Region Replication (existing objects don't replicate)

- Bucket name uniqueness

- Lifecycle transitions (one-way only!)

- Multi-part upload requirements

Sample: "Delete Standard-IA object after 15 days. What charges?"

STORAGE ARCHITECTURES (7 Questions):

- EBS AZ-locked (snapshot to move)

- EFS vs EBS (multiple instances = EFS)

- Boot volume restrictions (HDD cannot boot)

- EFS Linux-only trap (Windows = FSx)

- S3 not mountable as file system

- EBS Multi-Attach limits (16 instances, same AZ, io2 only)

- Cost optimization (One Zone-IA 90% savings)

Sample: "10 servers sharing files. EBS or EFS?"

AWS DATABASES (9 Questions):

- Multi-AZ vs Read Replicas (THE critical distinction!)

- Async replication = eventual consistency

- Aurora vs RDS failover times (30s vs 60-120s)

- Aurora storage auto-scaling (never runs out)

- Encryption trap (can't enable on existing)

- Redis vs Memcached (HA needs Redis)

- ElastiCache load reduction (80%+)

- Stopped RDS charges (storage continues)

- Aurora Global replication lag (<1 second)

Sample: "High read load. Enable Multi-AZ?" (NO - use Read Replicas!)

AMAZON ROUTE 53 (5 Questions):

- CNAME vs Alias for zone apex (THE trap!)

- Latency routing for performance

- Failover routing health checks (mandatory!)

- Geolocation default record requirement

- Health checks for private resources (CloudWatch alarms)

Sample: "Point example.com to load balancer. CNAME or Alias?"

🎯 SCORING GUIDE

30-35 correct: EXAM READY! ⭐⭐⭐⭐⭐

Strong mastery. Keep doing practice questions.

25-29 correct: VERY GOOD! ⭐⭐⭐⭐

On the right track. Review missed questions.

20-24 correct: GOOD FOUNDATION ⭐⭐⭐

Solid base but needs more study. Focus on weak areas.

15-19 correct: GAPS TO FILL ⭐⭐

Watch episodes again, take notes, re-quiz.

Below 15: NEEDS REVIEW ⭐

Don't worry! Material is complex. Rewatch Episodes 5.5-9.

💡 WHY ACTIVE RECALL WORKS

Research shows:

- Testing yourself = 2-3x better retention than re-reading

- Active recall strengthens memory connections

- Immediate feedback corrects misconceptions

- Spaced repetition with re-testing = long-term memory

HOW TO USE THIS EPISODE:

1. First attempt: Track your score

2. Review episodes for missed questions

3. Re-take quiz after 3 days

4. Re-take again before exam

5. Aim for 30+ correct on every attempt

📚 EPISODES COVERED:

Episode 6: Auto Scaling Groups

Episode 7: Amazon S3 Deep Dive

Episode 8: Storage Architectures (EBS vs EFS vs S3)

Episode 9: AWS Databases (RDS, Aurora, ElastiCache)

Episode 10: Amazon Route 53 (DNS & Traffic Routing)

Pro tip: Retake this quiz multiple times until you score 30+ consistently. That's exam-ready mastery!
