Episode 10.5: Exam Q&A - 35 Rapid-Fire Questions: ASG, S3, Storage, Databases & Route 53 | SAA-C03
Notes de l’épisode
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!
