Networking and Content Delivery test - AWS Certified Cloud Practitioner questions

Question 1

Which of the following features of Amazon CloudFront helps to protect against DDoS attacks?

Distribution of incoming traffic across multiple AWS regions for improved availability Automatic scaling of the origin server infrastructure during high traffic Integration with AWS Shield for additional DDoS protection Caching of frequently accessed content at edge locations to reduce origin server load

Correct Answer: Integration with AWS Shield for additional DDoS protection

Integration with AWS Shield provides additional DDoS protection for Amazon CloudFront. AWS Shield is a managed service that safeguards applications running on AWS against DDoS attacks. By integrating CloudFront with AWS Shield, it helps protect against DDoS attacks by providing detection and mitigation capabilities. The other options, while beneficial, do not directly protect against DDoS attacks. Caching content at edge locations reduces origin server load but does not prevent DDoS attacks. Automatic scaling of origin servers helps handle high traffic but is not a direct DDoS protection measure. Distributing traffic across multiple regions improves availability but does not specifically protect against DDoS attacks.

Question 2

What is the primary mechanism used by Amazon CloudFront to reduce latency and improve performance for end-users accessing web content?

CloudFront compresses and optimizes content at the origin server before distributing it to edge locations, resulting in faster content delivery to end-users. CloudFront leverages server-side rendering techniques to generate personalized content on-the-fly at edge locations, minimizing the latency experienced by end-users. CloudFront utilizes a global network of edge locations to cache and serve content closer to the end-users, reducing the distance data has to travel. CloudFront employs advanced routing algorithms to dynamically select the optimal path for content delivery between the origin server and the end-user's device.

Correct Answer: CloudFront utilizes a global network of edge locations to cache and serve content closer to the end-users, reducing the distance data has to travel.

The primary mechanism used by Amazon CloudFront to reduce latency and improve performance for end-users is caching and serving content from a global network of edge locations. By distributing content closer to the end-users, CloudFront reduces the distance that data needs to travel, resulting in faster content delivery and lower latency. Compressing and optimizing content at the origin server, employing advanced routing algorithms, or using server-side rendering techniques are not the primary mechanisms CloudFront uses to achieve this goal.

Question 3

Which of the following is a valid use case for Amazon CloudFront?

Securely storing and retrieving large amounts of objects and files with high durability Delivering static and dynamic web content with low latency and high data transfer speeds Providing a managed service for deploying and scaling containerized applications Hosting a relational database for a high-traffic website with stringent availability requirements

Correct Answer: Delivering static and dynamic web content with low latency and high data transfer speeds

Amazon CloudFront is a content delivery network (CDN) service that is designed to deliver static and dynamic web content with low latency and high data transfer speeds. It caches content at edge locations around the world, allowing users to access the content from the nearest location for faster delivery. Hosting a relational database, deploying containerized applications, and storing large amounts of objects are use cases for other AWS services such as Amazon RDS, Amazon ECS/EKS, and Amazon S3, respectively, but not for CloudFront.
