AWS Severless Quizzes

A cybersecurity company is running a serverless backend with several compute-heavy workflows running on Lambda functions. The development team has noticed a performance lag after analyzing the performance metrics for the Lambda functions.

As a Developer Associate, which of the following options would you suggest as the BEST solution to address the compute-heavy workloads?

• Increase the amount of memory available to the Lambda functions

• Invoke the Lambda functions asynchronously to process the compute-heavy workflows

• Use reserved concurrency to account for the compute-heavy workflows

• Use provisioned concurrency to account for the compute-heavy workflows

You are planning to use the Serverless Application model which will be used to deploy a serverless application consisting of a Node.js function. Which of the following steps need to be carried out? Choose 2 answers from the options given below.

• Use the Lambda package command.

• Use the SAM package command.

• Use the Lambda deploy command.

• Use the SAM deploy command.

You are a developer in a manufacturing company that has several servers on-site. The company decides to move new development to the cloud using serverless technology. You decide to use the AWS Serverless Application Model (AWS SAM) and work with an AWS SAM template file to represent your serverless architecture.

Which of the following is NOT a valid serverless resource type?

• AWS::Serverless::UserPool

• AWS::Serverless::Function

• AWS::Serverless::Api

• AWS::Serverless::SimpleTable

A media analytics company has built a streaming application on Lambda using Serverless Application Model (SAM).

As a Developer Associate, which of the following would you identify as the correct order of execution to successfully deploy the application?

• Develop the SAM template locally => upload the template to Lambda => deploy your application to the cloud

• Develop the SAM template locally => upload the template to CodeCommit => deploy your application to CodeDeploy

• Develop the SAM template locally => upload the template to S3 => deploy your application to the cloud

• Develop the SAM template locally => deploy the template to S3 => use your application in the cloud

Your company is planning to move away from reserving EC2 instances and would like to adopt a more agile form of serverless architecture.

Which of the folloiwng is the simplest and the least effort way of deploying the Docker containers on this serverless architecture?

• Amazon Elastic Container Service (Amazon ECS) on EC2

• Amazon Elastic Kubernetes Service (Amazon EKS) on Fargate

• Amazon Elastic Container Service (Amazon ECS) on Fargate

• AWS Elastic Beanstalk

Other than the Resources section, which of the following sections in a Serverless Application Model (SAM) Template is mandatory?

• Parameters

• Mappings

• Globals

• Transform

An IT company has migrated to a serverless application stack on the AWS Cloud with the compute layer being implemented via Lambda functions. The engineering managers would like to actively troubleshoot any failures in the Lambda functions.

As a Developer Associate, which of the following solutions would you suggest for this use-case?

• Use CloudWatch Events to identify and notify any failures in the Lambda code

• Use CodeCommit to identify and notify any failures in the Lambda code

• The developers should insert logging statements in the Lambda function code which are then available via CloudWatch logs

• Use CodeDeploy to identify and notify any failures in the Lambda code

You are looking to invoke an AWS Lambda function every hour (similar to a cron job) in a serverless way.

Which event source should you use for your AWS Lambda function?

• Amazon S3

• CloudWatch Events

• SQS

• Kinesis

You are assigned as the new project lead for a web application that processes orders for customers. You want to integrate event-driven processing anytime data is modified or deleted and use a serverless approach using AWS Lambda for processing stream events.

Which of the following databases should you choose from?

• DynamoDB

• RDS

• ElastiCache

• Kinesis

As a Developer, you are given a document written in YAML that represents the architecture of a serverless application. The first line of the document contains Transform: 'AWS::Serverless-2016-10-31'.

What does the Transform section in the document represent?

• It represents a Lambda function definition

• It represents an intrinsic function

• Presence of Transform section indicates it is a Serverless Application Model (SAM) template

• Presence of Transform section indicates it is a CloudFormation Parameter
