CLF-C02 Cloud Architecture & Deployment Principles

Question 1

What is a key benefit of using a multi-AZ deployment for applications on AWS?

Accepted Answer

It ensures high availability and fault tolerance

Answer

A multi-AZ (Availability Zone) deployment for applications on AWS is a key strategy to ensure high availability and fault tolerance. By distributing application components across multiple physically distinct Availability Zones within a region, your application can withstand the failure of a single AZ without downtime. This architecture significantly improves resilience and business continuity.

Question 2

Which AWS service allows you to launch and manage virtual servers?

Accepted Answer

Amazon EC2

Answer

Amazon EC2 (Elastic Compute Cloud) is the AWS service that allows you to launch and manage virtual servers, known as instances, in the cloud. You can choose from various instance types, operating systems, and storage options to meet your application's specific needs. EC2 provides scalable compute capacity, enabling you to run a wide range of workloads.

Question 3

Why are stateless applications ideal for cloud deployment?

Accepted Answer

They can scale and recover more efficiently

Answer

Stateless applications are ideal for cloud deployment because they do not store any session-specific data on the server, making each request independent. This characteristic allows them to be easily scaled horizontally by adding more instances without complex data synchronization. Furthermore, they can recover more efficiently from failures, as any instance can serve any request without losing user context, enhancing resilience and elasticity.

Question 4

What is the role of Amazon CloudFront in cloud architecture?

Accepted Answer

Content delivery with low latency

Answer

Amazon CloudFront is a Content Delivery Network (CDN) service. Its primary role is to securely deliver data, videos, applications, and APIs to customers globally with low latency. It achieves this by caching content at edge locations closer to users, reducing the distance data needs to travel.

Question 5

Which design principle promotes system reliability in AWS?

Accepted Answer

Design for failure

Answer

The 'Design for failure' principle in AWS promotes system reliability by anticipating that components will inevitably fail. Instead of trying to prevent all failures, this principle focuses on designing systems that can gracefully handle and recover from failures, ensuring continuous availability and resilience.
