QUESTION: 71

A developer is working on an existing application that uses Amazon DynamoDB as its data store. The DynamoDB table has the following attributes: partNumber (partition key), vendor (sort key), description, productFamily, and productType. When the developer analyzes the usage patterns, the developer notices that there are application modules that frequently look for a list of products based on the productFamily and productType attributes.
The developer wants to make changes to the application to improve performance of the query operations.
Which solution will meet these requirements?

Create a global secondary index (GSI) with productFamily as the partition key and productType as the sort key.
Create a local secondary index (LSI) with productFamily as the partition key and productType as the sort key.
Recreate the table. Add partNumber as the partition key and vendor as the sort key. During table creation, add a local secondary index (LSI) with productFamily as the partition key and productType as the sort key.
Update the queries to use Scan operations with productFamily as the partition key and productType as the sort key.

QUESTION: 72

A developer creates a VPC named VPC-A that has public and private subnets. The developer also creates an Amazon RDS database inside the private subnet of VPC-A. To perform some queries, the developer creates an AWS Lambda function in the default VPC. The Lambda function has code to access the RDS database. When the Lambda function runs, an error message indicates that the function cannot connect to the RDS database.
How can the developer solve this problem?

Modify the RDS security group. Add a rule to allow traffic from all the ports from the VPC CIDR block.
Redeploy the Lambda function in the same subnet as the RDS instance. Ensure that the RDS security group allows traffic from the Lambda function.
Create a security group for the Lambda function. Add a new rule in the RDS security group to allow traffic from the new Lambda security group.
Create an IAM role. Attach a policy that allows access to the RDS database. Attach the role to the Lambda function.

QUESTION: 73

A company runs an application on AWS. The company deployed the application on Amazon EC2 instances. The application stores data on Amazon Aurora.
The application recently logged multiple application-specific custom DECRYP_ERROR errors to Amazon CloudWatch logs. The company did not detect the issue until the automated tests that run every 30 minutes failed. A developer must implement a solution that will monitor for the custom errors and alert a development team in real time when these errors occur in the production environment.
Which solution will meet these requirements with the LEAST operational overhead?

Configure the application to create a custom metric and to push the metric to CloudWatch. Create an AWS CloudTrail alarm. Configure the CloudTrail alarm to use an Amazon Simple Notification Service (Amazon SNS) topic to send notifications.
Create an AWS Lambda function to run every 5 minutes to scan the CloudWatch logs for the keyword DECRYP_ERROR. Configure the Lambda function to use Amazon Simple Notification Service (Amazon SNS) to send a notification.
Use Amazon CloudWatch Logs to create a metric filter that has a filter pattern for DECRYP_ERROR. Create a CloudWatch alarm on this metric for a threshold >=1. Configure the alarm to send Amazon Simple Notification Service (Amazon SNS) notifications.
Install the CloudWatch unified agent on the EC2 instance. Configure the application to generate a metric for the keyword DECRYP_ERROR errors. Configure the agent to send Amazon Simple Notification Service (Amazon SNS) notifications.

QUESTION: 74

A developer created an AWS Lambda function that accesses resources in a VPC. The Lambda function polls an Amazon Simple Queue Service (Amazon SQS) queue for new messages through a VPC endpoint. Then the function calculates a rolling average of the numeric values that are contained in the messages. After initial tests of the Lambda function, the developer found that the value of the rolling average that the function returned was not accurate.
How can the developer ensure that the function calculates an accurate rolling average?

Set the function's reserved concurrency to 1. Calculate the rolling average in the function. Store the calculated rolling average in Amazon ElastiCache.
Modify the function to store the values in Amazon ElastiCache. When the function initializes, use the previous values from the cache to calculate the rolling average.
Set the function's provisioned concurrency to 1. Calculate the rolling average in the function. Store the calculated rolling average in Amazon ElastiCache.
Modify the function to store the values in the function's layers. When the function initializes, use the previously stored values to calculate the rolling average.

Amazon AWS Certified Developer - Associate DVA-C02: Skills Tested, Job Roles, and Study Tips

The AWS Certified Developer - Associate DVA-C02 certification is designed for individuals who perform a developer role and have one or more years of hands-on experience developing and maintaining applications on the Amazon Web Services platform. This certification validates a candidate's ability to demonstrate an in-depth understanding of core AWS services, uses, and basic AWS architecture best practices. Employers across various industries, from startups to large enterprises, seek professionals with this credential because it confirms the holder can write, deploy, and debug cloud-based applications using AWS. By achieving this certification, developers prove they possess the technical proficiency required to build secure and scalable cloud applications, which is a critical function in modern software engineering teams.

What the AWS Certified Developer - Associate DVA-C02 Exam Covers

The exam evaluates a candidate's proficiency across several critical domains, including development with AWS services, security, deployment, and troubleshooting and optimization. In practical terms, this means a developer must understand how to write code that interacts with AWS services like Amazon DynamoDB, Amazon SQS, and Amazon SNS, while also implementing appropriate security measures such as IAM policies and encryption. Deployment is a major focus, requiring knowledge of CI/CD pipelines, AWS Elastic Beanstalk, and AWS CloudFormation to automate the release of software. Troubleshooting and optimization require the ability to identify performance bottlenecks and resolve issues using tools like Amazon CloudWatch and AWS X-Ray. Our practice questions are structured to mirror these real-world scenarios, ensuring that candidates are tested on their ability to apply these concepts rather than just recalling definitions.

Among these domains, the development with AWS services and troubleshooting areas are often considered the most technically demanding by candidates. These sections require a deep understanding of how different services interact within an application architecture, often presenting complex scenarios where multiple services must be configured correctly to achieve a specific outcome. Candidates must demonstrate not only knowledge of individual service features but also the ability to diagnose why an application might be failing or underperforming in a cloud environment. This level of technical depth necessitates consistent practice, as the exam frequently tests the nuances of service limits, API calls, and integration patterns that are only mastered through hands-on experience.
