Amazon DVA-C02 Exam is a certification that validates the skills and knowledge of developers who want to work with Amazon Web Services (AWS). AWS Certified Developer - Associate certification is designed to test the candidate's proficiency in deploying, debugging, and maintaining AWS cloud-based applications. It also tests their understanding of AWS core services such as Lambda, S3, EC2, and DynamoDB.
NEW QUESTION # 534
A developer is designing a serverless application with two AWS Lambda functions to process photos. One Lambda function stores objects in an Amazon S3 bucket and stores the associated metadata in an Amazon DynamoDB table. The other Lambda function fetches the objects from the S3 bucket by using the metadata from the DynamoDB table. Both Lambda functions use the same Python library to perform complex computations and are approaching the quota for the maximum size of zipped deployment packages.
What should the developer do to reduce the size of the Lambda deployment packages with the LEAST operational overhead?
Answer: D
Explanation:

NEW QUESTION # 535
A developer is creating an application that will store personal health information (PHI). The PHI needs to be encrypted at all times. An encrypted Amazon RDS for MySQL DB instance is storing the data. The developer wants to increase the performance of the application by caching frequently accessed data while adding the ability to sort or rank the cached datasets.
Which solution will meet these requirements?
Answer: C
Explanation:
You can use Amazon Elasticache for Redis Sorted Sets to easily implement a dashboard that keeps a list of sorted data by their rank.

NEW QUESTION # 536
An online food company provides an Amazon API Gateway HTTP API 1o receive orders for partners. The API is integrated with an AWS Lambda function. The Lambda function stores the orders in an Amazon DynamoDB table.
The company expects to onboard additional partners Some to me panthers require additional Lambda function to receive orders. The company has created an Amazon S3 bucket. The company needs 10 store all orders and updates m the S3 bucket for future analysis How can the developer ensure that an orders and updates are stored to Amazon S3 with the LEAST development effort?
Answer: C
Explanation:
This solution will ensure that all orders and updates are stored to Amazon S3 with the least development effort because it uses DynamoDB Streams to capture changes in the DynamoDB table and trigger a Lambda function to write those changes to the S3 bucket. This way, the original Lambda function and API Gateway API endpoint do not need to be modified, and no additional services are required. Option A is not optimal because it will require more development effort to create a new Lambda function and a new API Gateway API endpoint, and to modify the original Lambda function to post updates to the new API endpoint. Option B is not optimal because it will introduce additional costs and complexity to use Amazon Kinesis Data Streams to create a new data stream, and to modify the Lambda function to publish orders to the data stream. Option D is not optimal because it will require more development effort to modify the Lambda function to publish to a new Amazon SNS topic, and to create and subscribe a new Lambda function to the topic.

NEW QUESTION # 537
A developer is testing an application that invokes an AWS Lambda function asynchronously.
During the testing phase, the Lambda function fails to process after two retries. How can the developer troubleshoot the failure?
Answer: C
Explanation:
Dead Letter Queues (DLQ) can be configured for Lambda functions to capture failed asynchronous invocations. Events that cannot be processed will be sent to an SQS queue (or an SNS topic) you specify, allowing for further investigation and reprocessing.
