Serverless test - AWS Certified Cloud Practitioner questions

Question 1

Which of the following statements about AWS Lambda is true?

Lambda functions can only be written in Python and are solely triggered by Amazon S3 events Lambda supports code written in multiple programming languages and can be triggered by various AWS services and API calls Lambda is designed for running long-running, resource-intensive applications and batch processing workloads Lambda requires provisioning and managing underlying compute resources, but offers automatic scaling capabilities

Correct Answer: Lambda supports code written in multiple programming languages and can be triggered by various AWS services and API calls

The correct statement about AWS Lambda is that it supports code written in multiple programming languages and can be triggered by various AWS services and API calls. Lambda is a serverless compute service that allows running code without provisioning or managing servers. It supports languages such as Node.js, Python, Java, C#, Go, and more. Lambda functions can be triggered by events from services like Amazon S3, DynamoDB, API Gateway, and others. The other statements are incorrect because Lambda is not limited to Python or S3 triggers, it is designed for short-running and event-driven workloads rather than long-running or batch processing, and it does not require managing underlying compute resources as it is a fully managed serverless service.

Question 2

Which of the following is a key advantage of using AWS Lambda for serverless computing?

AWS Lambda eliminates the need to write any code, as it automatically generates functions based on requirements. AWS Lambda provides a fixed pool of compute resources that can be allocated to individual functions. AWS Lambda automatically scales based on the incoming workload without manual intervention. AWS Lambda functions can run indefinitely as long as there is available memory and CPU resources.

Correct Answer: AWS Lambda automatically scales based on the incoming workload without manual intervention.

AWS Lambda automatically scales the number of function instances based on the incoming request volume. It dynamically allocates the necessary compute resources to handle the workload, and scales down when the traffic decreases. This eliminates the need for manual scaling and ensures optimal utilization of resources. The other options are incorrect because: Lambda functions have execution time limits and cannot run indefinitely, Lambda requires writing code and does not automatically generate functions, and Lambda does not provide a fixed pool of resources but rather scales dynamically.

Question 3

Which of the following is a key characteristic of AWS Lambda?

AWS Lambda requires manual provisioning of compute resources AWS Lambda automatically scales based on the number of incoming events AWS Lambda functions can run indefinitely without time limitations AWS Lambda is designed for long-running, resource-intensive workloads

Correct Answer: AWS Lambda automatically scales based on the number of incoming events

AWS Lambda is a serverless compute service that automatically scales based on the number of incoming events or requests. It is designed to run code in response to events without the need for manual provisioning or management of servers. Lambda functions have a maximum execution time limit and are suitable for short-running, event-driven tasks. The other options incorrectly state that Lambda requires manual provisioning, can run indefinitely, or is designed for long-running, resource-intensive workloads, which are not true characteristics of AWS Lambda.
