CCP AWS Cloud Architecture and Design Principles 1 — Questions and Answers
Question 1: Which AWS Well-Architected Framework pillar focuses on protecting data, systems, and assets through risk assessments and mitigation?
- Reliability
- Performance Efficiency
- Security (Correct answer)
- Cost Optimization
Correct answer: Security
The Security pillar of the Well-Architected Framework covers identity management, detecting incidents, protecting data, and automating security best practices.
Question 2: Which AWS Well-Architected pillar focuses on the ability of a system to recover from failures and meet demand?
- Operational Excellence
- Security
- Reliability (Correct answer)
- Sustainability
Correct answer: Reliability
The Reliability pillar addresses designing systems that can recover from infrastructure failures, scale to meet demand, and mitigate disruptions.
Question 3: What is the purpose of deploying resources across multiple Availability Zones in AWS?
- To reduce data transfer costs
- To improve fault tolerance and eliminate single points of failure (Correct answer)
- To comply with GDPR requirements
- To enable global latency routing
Correct answer: To improve fault tolerance and eliminate single points of failure
Multi-AZ deployments ensure that if one data center fails, your workload continues running in another AZ, eliminating single points of failure.
Question 4: What does 'designing for failure' mean in AWS cloud architecture?
- Expecting systems to always fail
- Building systems that assume component failures will happen and remain operational anyway (Correct answer)
- Reducing feature scope to avoid bugs
- Running systems in degraded mode permanently
Correct answer: Building systems that assume component failures will happen and remain operational anyway
Designing for failure means architecting systems with redundancy and auto-recovery so they remain available even when individual components fail.
Question 5: Which architectural pattern decouples application components so they can scale and fail independently?
- Monolithic architecture
- Tight coupling
- Loose coupling (Correct answer)
- Hard coding
Correct answer: Loose coupling
Loose coupling uses queues, APIs, or events to separate components, so failures or scaling needs in one part don't directly impact others.
Question 6: Which AWS service helps implement loose coupling by allowing components to communicate asynchronously via message queues?
- Amazon SNS
- Amazon SQS (Correct answer)
- AWS Step Functions
- Amazon EventBridge
Correct answer: Amazon SQS
Amazon SQS (Simple Queue Service) provides a managed message queue that decouples producers and consumers, enabling asynchronous and fault-tolerant communication.
