Your application needs to store user session data that can be retrieved quickly. Which AWS service would be most suitable for this requirement?
Amazon DynamoDB is a NoSQL database service that provides single-digit millisecond response times, making it ideal for storing session data. It is fully managed, highly available, and can handle high volumes of reads and writes, making it a perfect choice for storing and retrieving user session information quickly.
Your application on AWS needs to perform background processing on a large batch of data. Which service allows you to run code without provisioning or managing servers and is suitable for this use case?
AWS Lambda is a serverless compute service that enables you to run code without managing the underlying infrastructure. It is ideal for background processing tasks and can automatically scale based on workload, making it a great fit for processing data in batches without needing to provision or manage servers.
You have an application that frequently writes and reads small objects, and you want to optimize for low-latency access. Which storage class should you use for maximum performance?
Amazon S3 Standard is optimized for low-latency access to frequently accessed data. It’s suitable for applications that require high-performance access to small objects, ensuring that the data is available and retrievable with minimal delay.
Which AWS service allows you to securely store and manage access to secrets, such as API keys and database credentials, needed by your application?
AWS Secrets Manager is a service that helps manage, retrieve, and rotate secrets securely. It’s designed for securely storing sensitive information, like API keys and database credentials, allowing controlled access through AWS Identity and Access Management (IAM) policies and other security controls.
You are developing an application that needs to interact with Amazon S3 to upload and retrieve files. Which AWS SDK feature should you use to simplify the integration?
The AWS SDK (Software Development Kit) provides APIs in various programming languages to interact with AWS services, including Amazon S3. Using the SDK simplifies tasks such as uploading, retrieving, and managing files within your application code, eliminating the need for extensive integration work.
