Question 96

A company is migrating legacy internal applications to AWS. Leadership wants to rewrite the internal employee directory to use native AWS services. A developer needs to create a solution for storing employee contact details and high-resolution photos for use with the new application.

Which solution will enable the search and retrieval of each employee's individual details and high-resolution photos using AWS APIs?

Options:

Encode each employee's contact information and photos using Base64. Store the information in an Amazon DynamoDB table using a sort key.

Store each employee's contact information in an Amazon DynamoDB table along with the object keys for the photos stored in Amazon S3.

Use Amazon Cognito user pools to implement the employee directory in a fully managed software-as-a-service (SaaS) method.

Store employee contact information in an Amazon RDS DB instance with the photos stored in Amazon Elastic File System (Amazon EFS).

I've heard that Cramkey is one of the best websites for exam dumps. They have a high passing rate and the questions are always up-to-date. Is it true?

Cian Sep 26, 2024

Definitely. The dumps are constantly updated to reflect the latest changes in the certification exams. And I also appreciate how they provide explanations for the answers, so I could understand the reasoning behind each question.

Hey I passed my exam. The world needs to know about it. I have never seen real exam questions on any other exam preparation resource like I saw on Cramkey Dumps.

Niamh Oct 15, 2024

That's true. Cramkey Dumps are simply the best when it comes to preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

River

Hey, I used Cramkey Dumps to prepare for my recent exam and I passed it.

Lewis Sep 11, 2024

Yeah, I used these dumps too. And I have to say, I was really impressed with the results.

Osian

Dumps are fantastic! I recently passed my certification exam using these dumps and I must say, they are 100% valid.

Azaan Aug 8, 2024

They are incredibly accurate and valid. I felt confident going into my exam because the dumps covered all the important topics and the questions were very similar to what I saw on the actual exam. The team of experts behind Cramkey Dumps make sure the information is relevant and up-to-date.

Anaya

I found so many of the same questions on the real exam that I had already seen in the Cramkey Dumps. Thank you so much for making exam so easy for me. I passed it successfully!!!

Nina Oct 14, 2024

It's true! I felt so much more confident going into the exam because I had already seen and understood the questions.

Question 97

A company uses more than 100 AWS Lambda functions to handle application services. One Lambda function is critical and must always run successfully. The company notices that occasionally, the critical Lambda function does not initiate. The company investigates the issue and discovers instances of the Lambda TooManyRequestsException: Rate Exceeded error in Amazon CloudWatch logs. Upon further review of the logs, the company notices that some of the non-critical functions run properly while the critical function fails. A developer must resolve the errors and ensure that the critical Lambda function runs successfully. Which solution will meet these requirements with the LEAST operational overhead?

Options:

Configure reserved concurrency for the critical Lambda function. Set reserved concurrent executions to the appropriate level.

Configure provisioned concurrency for the critical Lambda function. Set provisioned concurrent executions to the appropriate level.

Configure CloudWatch alarms for TooManyRequestsException errors. Add the critical Lambda function as an alarm state change action to invoke the critical function again after a failure.

Configure CloudWatch alarms for TooManyRequestsException errors. Add Amazon EventBridge as an action for the alarm state change. Use EventBridge to invoke the critical function again after a failure.

Question 98

A developer previously deployed an AWS Lambda function as a .zip package. The developer needs to deploy the Lambda function as a container.

Options:

Create an Amazon ECR repository in the same AWS Region as the Lambda function. Package the Lambda function into a container image. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function configuration to specify the repository URI and container image tag.

Create an AWS SAM template that defines the Lambda function and its resources as code. Include a container image in the template, and store the container image in an Amazon S3 bucket. Deploy the AWS SAM template. Specify the S3 bucket URI.

Create an AWS CloudFormation template that defines the Lambda function and its resources as code. Include a container image in the template, and store the image in an Amazon S3 bucket. Deploy the CloudFormation template. Specify the S3 bucket URI.

Create an Amazon ECR repository in the same AWS Region as the Lambda function. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function to use the new image by specifying the repository URI.

Question 99

A company needs to package and deploy an application that uses AWS Lambda to compress and decompress video clips. The application uses a video codec library that is larger than 250 MB. The application uses the library to compress the videos before storage and to decompress the videos upon retrieval.

Options:

Create one Lambda function. Upload one zip file that contains code to handle video compression and decompression to the function. Include the codec library in the zip file.

Create two Lambda functions. Upload one zip file that contains code to handle video compression to one function. Upload a second zip file that contains code for video decompression to the second function. Include the codec library in both zip files.

Create two Lambda functions. Build one container image that contains code to handle video compression and a second image that contains video decompression code. Add the codec library to both images. Upload the images to Amazon ECR. Use the containers to create the Lambda functions.
