Amazon AWS Certified Developer - Associate Sample Questions (Q677-Q682):

NEW QUESTION # 677
A developer needs to migrate an online retail application to AWS to handle an anticipated increase in traffic.
The application currently runs on two servers: one server for the web application and another server for the database. The web server renders webpages and manages session state in memory. The database server hosts a MySQL database that contains order details. When traffic to the application is heavy, the memory usage for the web server approaches 100% and the application slows down considerably.
The developer has found that most of the memory increase and performance decrease is related to the load of managing additional user sessions. For the web server migration, the developer will use Amazon EC2 instances with an Auto Scaling group behind an Application Load Balancer.
Which additional set of changes should the developer make to the application to improve the application's performance?

A. Use Amazon ElastiCache for Memcached to store and manage the session data. Use an Amazon RDS for MySQL DB instance to store the application data.
B. Use an EC2 instance to host the MySQL database. Store the session data and the application data in the MySQL database.
C. Use the EC2 instance store to manage the session data. Use an Amazon RDS for MySQL DB instance to store the application data.
D. Use Amazon ElastiCache for Memcached to store and manage the session data and the application data.

Answer: A

Explanation:
Explanation
Using Amazon ElastiCache for Memcached to store and manage the session data will reduce the memory load and improve the performance of the web server. Using Amazon RDS for MySQL DB instance to store the application data will provide a scalable, reliable, and managed database service. Option A is not optimal because it does not address the memory issue of the web server. Option C is not optimal because it does not provide a persistent storage for the application data. Option D is not optimal because it does not provide a high availability and durability for the session data.

NEW QUESTION # 678
A company uses Amazon API Gateway to expose a set of APIs to customers. The APIs have caching enabled in API Gateway. Customers need a way to invalidate the cache for each API when they test the API.
What should a developer do to give customers the ability to invalidate the API cache?

A. Ask the customers to use AWS credentials to call the InvalidateCache API operation.
B. Ask the customers to use the AWS SDK API Gateway class to invoke the InvalidateCache API operation.
C. Attach an InvalidateCache policy to the IAM execution role that the customers use to invoke the API.Ask the customers to add the INVALIDATE_CACHE query string parameter when they make an API call.
D. Attach an InvalidateCache policy to the IAM execution role that the customers use to invoke the API.
Ask the customers to send a request that contains the HTTP header when they make an API call.

Answer: C

NEW QUESTION # 679
A company's developer has deployed an application in AWS by using AWS CloudFormation The CloudFormation stack includes parameters in AWS Systems Manager Parameter Store that the application uses as configuration settings. The application can modify the parameter values When the developer updated the stack to create additional resources with tags, the developer noted that the parameter values were reset and that the values ignored the latest changes made by the application. The developer needs to change the way the company deploys the CloudFormation stack. The developer also needs to avoid resetting the parameter values outside the stack.
Which solution will meet these requirements with the LEAST development effort?

A. Create an Amazon DynamoDB table as a resource in the CloudFormation stack to hold configuration data for the application Migrate the parameters that the application is modifying from Parameter Store to the DynamoDB table
B. Modify the CloudFormation stack to set the deletion policy to Retain for the Parameter Store parameters.
C. Create an Amazon RDS DB instance as a resource in the CloudFormation stack. Create a table in the database for parameter configuration. Migrate the parameters that the application is modifying from Parameter Store to the configuration table
D. Modify the CloudFormation stack policy to deny updates on Parameter Store parameters

Answer: B

Explanation:
* Problem: CloudFormation updates reset Parameter Store parameters, disrupting application behavior.
* Deletion Policy: CloudFormation has a deletion policy that controls resource behavior when a stack is deleted or updated. The 'Retain' policy instructs CloudFormation to preserve a resource's current state.
* Least Development Effort: This solution involves a simple CloudFormation template modification, requiring minimal code changes.

NEW QUESTION # 680
A developer compiles an AWS Lambda function and packages the result as a .zip file. The developer uses the Functions page on the Lambda console to attempt to upload the local packaged .zip file. When pushing the package to Lambda, the console returns the following error:

Which solutions can the developer use to publish the code? (Choose two.)

A. Use the update-function-code AWS CLI command. Pass the --publish parameter.
B. Create an AWS Support ticket to increase the maximum package size.
C. Repackage the Lambda function as a Docker container image. Upload the image to Amazon Elastic Container Registry (Amazon ECR). Create a new Lambda function by using the Lambda console. Reference the image that is deployed to Amazon ECR.
D. Sign the .zip file digitally. Create a new Lambda function by using the Lambda console. Update the configuration of the new Lambda function to include the Amazon Resource Name (ARN) of the code signing configuration.
E. Upload the package to Amazon 3. Use the Functions page on the Lambda console to upload the package from the S3 location.

Answer: C,E

NEW QUESTION # 681
A developer is building an application on AWS. The application includes an AWS Lambda function that processes messages from an Amazon Simple Queue Service (Amazon SQS) queue.
The Lambda function sometimes fails or times out. The developer needs to figure out why the Lambda function fails to process some messages.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create a dead-letter queue. Configure the Lambda function to send the failed messages to the dead-letter queue.
B. Create an Amazon DynamoDB table. Update the Lambda function to send the failed messages to the DynamoDB table.
C. Increase the maximum timeout of the Lambda function to 15 minutes. Check the AWS CloudTrail event history for error details.
D. Increase the visibility timeout of the SQS queue. Check logs in Amazon CloudWatch Logs for error details.

Answer: A
