Question 1

A developer received the following error message during an AWS CloudFormation deployment:

Which action should the developer take to resolve this error?

Options :

A : Manually delete the security group. Then execute a change set to force deletion of the CloudFormation stack.

B : Add a DependsOn attribute to the sg-11223344 resource in the CloudFormation template. Then delete the stack.

C : Update the logical ID of the security group resource with the security groups ARN. Then delete the stack.

D :

Modify the CloudFormation template to retain the ASGInstanceRolet 2345678 resource. Then manually delete the resource after deployment.

Answer: D

Question 2

A developer is creating an AWS Lambda function that is invoked by messages to an Amazon Simple Notification Service (Amazon SNS) topic. The messages represent customer data updates from a customer relationship management (CRM) system

The developer wants the Lambda function to process only the messages that pertain to email address changes. Additional subscribers to the SNS topic will process any other messages.

Which solution will meet these requirements in the LEAST development effort?

Options :

A : Use Lambda event filtering to allow only messages that are related to email address changes to invoke the Lambda function.

B : Use an SNS filter policy on the Lambda function subscription to allow only messages that are related to email address changes to invoke the Lambda function.

C : Subscribe an Amazon Simple Queue Service (Amazon SQS) queue to the SNS topic. Configure the SQS queue with a filter policy to allow only messages that are related to email address changes.

Connect the SQS queue to the Lambda function.

D : Configure the Lambda code to check the received message. If the message is not related to an email address change, configure the Lambda function to publish the message back to the SNS topic for the other subscribers to process.

Answer: B

Question 3

An Amazon Simple Queue Service (Amazon SQS) queue serves as an event source for an AWS Lambda function In the SQS queue, each item corresponds to a video file that the Lambda function must convert to a smaller resolution The Lambda function is timing out on longer video files, but the Lambda function's timeout is already configured to its maximum value What should a developer do to avoid the timeouts without additional code changes'?

Options :

A : Increase the memory configuration of the Lambda function.

B : Increase the visibility timeout on the SQS queue.

C : Increase the instance size of the host that runs the Lambda function.

D : Use multi-threading for the conversion.

Answer: B

Question 4

A company is using AWS Lambda for processing small images that are uploaded to Amazon S3. This was working well until a large number of small files (several thousand) were recently uploaded and an error was generated by AWS Lambda (status code 429).

What is the MOST likely cause?

Options :

A : The event source mapping has not been configured

B : Amazon S3 could not handle the sudden burst in traffic

C : Lambda cannot process multiple files simultaneously

D : The concurrency execution limit for the account has been exceeded

Answer: D

Question 5

A developer needs to deploy an application running on AWS Fargate using Amazon ECS The application has environment variables that must be passed to a container for the application to initialize. How should the environment variables be passed to the container?

Options :

A : Define an array that includes the environment variables under the environment parameter within the service definition.

B : Define an array that includes the environment variables under the environment parameter within the task definition.

C : Define an array that includes the environment variables under the entryPoint parameter within the task definition.

D : Define an array that includes the environment variables under the entryPoint parameter within the service definition.

Answer: B
