CLF-C02 AWS Architecture 3 — Questions and Answers
Question 1: Which AWS Well-Architected Framework pillar focuses on protecting information and systems?
- Reliability
- Performance Efficiency
- Security (Correct answer)
- Cost Optimization
Correct answer: Security
The Security pillar encompasses the ability to protect data, systems, and assets to take advantage of cloud technologies to improve security.
Question 2: What is the primary purpose of Amazon CloudFront in an AWS architecture?
- Managing DNS records
- Distributing content with low latency via edge locations (Correct answer)
- Storing large datasets
- Running containerized applications
Correct answer: Distributing content with low latency via edge locations
Amazon CloudFront is a CDN that delivers content through a global network of edge locations, reducing latency for end users.
Question 3: Which AWS architecture principle suggests avoiding manual processes and using automation wherever possible?
- Automate to make architectural experimentation easier (Correct answer)
- Stop guessing capacity needs
- Test systems at production scale
- Allow for evolutionary architectures
Correct answer: Automate to make architectural experimentation easier
Automating changes allows you to create and replicate workloads at low cost and avoid the expense of manual effort.
Question 4: A company needs to run code in response to events without provisioning servers. Which AWS service best fits this need?
- Amazon EC2
- Amazon ECS
- AWS Lambda (Correct answer)
- AWS Elastic Beanstalk
Correct answer: AWS Lambda
AWS Lambda is a serverless compute service that runs code in response to events and automatically manages the underlying compute resources.
Question 5: What is the purpose of an AWS Virtual Private Cloud (VPC)?
- To provide a CDN for faster content delivery
- To provision logically isolated sections of the AWS cloud (Correct answer)
- To manage DNS for AWS resources
- To automate infrastructure deployment
Correct answer: To provision logically isolated sections of the AWS cloud
A VPC lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network you define.
Question 6: Which service allows you to define your AWS infrastructure as code using templates?
- AWS CloudTrail
- AWS CloudFormation (Correct answer)
- AWS Config
- AWS Systems Manager
Correct answer: AWS CloudFormation
AWS CloudFormation enables you to model and provision AWS infrastructure resources using templates, following infrastructure-as-code practices.
Question 7: What does the 'loose coupling' design principle mean in AWS architecture?
- Combining multiple services into a single monolithic application
- Reducing interdependencies between components so failures are isolated (Correct answer)
- Using the fewest services possible to reduce complexity
- Tightly integrating databases with application servers
Correct answer: Reducing interdependencies between components so failures are isolated
Loose coupling reduces interdependencies between components, meaning a change or failure in one component doesn't cascade to others.
