20+ practice questions focused on Cloud Technology and Services — one of the most tested topics on the AWS Certified Cloud Practitioner CLF-C02 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cloud Technology and Services PracticeA healthcare company needs to store patient medical records that must be retained for 10 years to comply with regulatory requirements. These records are accessed very rarely, only in the event of an audit or legal request. Which Amazon S3 storage class is the MOST cost-effective choice for this data?
Explanation: S3 Glacier Deep Archive is the most cost-effective choice because it is designed for long-term retention of rarely accessed data with a retrieval time of 12–48 hours. The 10-year retention requirement and infrequent access pattern (only during audits or legal requests) align perfectly with this storage class, offering the lowest storage cost among S3 classes while still meeting compliance needs.
A company hosts a static website on Amazon S3. The website serves product images and documents to customers around the world. Users in distant regions report slow load times. The company wants to reduce latency for all users without changing the existing S3 bucket configuration. Which AWS service should the company use?
Explanation: Amazon CloudFront is a content delivery network (CDN) that caches static content (e.g., images, documents) at edge locations worldwide. By distributing content from the nearest edge location to the user, CloudFront significantly reduces latency without requiring any changes to the existing S3 bucket configuration. The origin remains the S3 bucket, and CloudFront handles the global distribution automatically.
A company is developing a microservices application on AWS. The application includes a front-end web tier and a backend order processing service. The front-end sends order requests to the backend, which may take several seconds to process. The company wants to ensure that the front-end does not wait for the backend to complete, and that no orders are lost if the backend service is temporarily unavailable. Which AWS service should the company use to decouple the front-end and backend?
Explanation: Amazon Simple Queue Service (SQS) is the correct choice because it provides a fully managed message queue that decouples the front-end and backend services. The front-end can send order requests to an SQS queue and immediately return a response, while the backend processes messages asynchronously. SQS also stores messages durably across multiple Availability Zones, ensuring no orders are lost even if the backend is temporarily unavailable.
A development team is building a serverless application that processes image uploads to Amazon S3. The application needs to automatically generate a thumbnail version of each uploaded image and store it in a separate S3 bucket. The team wants to minimize operational overhead and only pay for the compute time used during thumbnail generation. Which AWS service should the team use to execute the thumbnail generation code in response to S3 upload events?
Explanation: AWS Lambda is the correct choice because it is a serverless compute service that can be triggered directly by S3 events (e.g., s3:ObjectCreated:*). This allows the thumbnail generation code to run automatically in response to each image upload, with no servers to manage and billing based only on the compute time consumed during execution.
A company runs a web application on multiple Amazon EC2 instances that are behind an Application Load Balancer. The operations team wants to ensure that if any EC2 instance fails, a new instance is automatically launched to replace it and maintain a minimum number of running instances. Which AWS service should the company use to meet this requirement?
Explanation: Amazon EC2 Auto Scaling is the correct service because it automatically launches new EC2 instances to replace failed ones and maintains a specified minimum number of running instances. It integrates with the Application Load Balancer to register new instances and deregister failed ones, ensuring the web application remains available. This directly meets the requirement for automatic instance replacement and capacity maintenance.
