Amazon AWS Certified Developer - Associate Sample Questions (Q42-Q47):

NEW QUESTION # 42
A developer is updating the production version of an AWS Lambda function to fix a defect. The developer has tested the updated code in a test environment. The developer wants to slowly roll out the updates to a small subset of production users before rolling out the changes to all users.
Only 10% of the users should be initially exposed to the new code in production.
Which solution will meet these requirements?

  • A. Update the Lambda code and create a new version of the Lambda function. Create a Lambda proxy integration. Configure the Lambda proxy to split traffic between the two Lambda function versions. Send 90% of the traffic to the production version, and send 10% of the traffic to the new version.
  • B. Update the Lambda code and create a new version of the Lambda function. Create a Lambda function trigger. Configure the traffic weights in the trigger between the two Lambda function versions. Send 90% of the traffic to the production version, and send 10% of the traffic to the new version.
  • C. Update the Lambda code and create a new version of the Lambda function. Create a Lambda function alias. Configure the traffic weights in the Lambda alias between the two Lambda function versions. Send 90% of the traffic to the production version, and send 10% of the traffic to the new version.
  • D. Create a new Lambda function that uses the updated code. Create a Lambda alias for the production Lambda function. Configure the Lambda alias to send 90% of the traffic to the production Lambda function, and send 10% of the traffic to the test Lambda function.

Answer: C


NEW QUESTION # 43
A developer is building a new application on AWS. The application uses an AWS Lambda function that retrieves information from an Amazon DynamoDB table. The developer hard coded the DynamoDB table name into the Lambda function code. The table name might change over time. The developer does not want to modify the Lambda code if the table name changes.
Which solution will meet these requirements MOST efficiently?

  • A. Store the table name in a file. Store the file in the /tmp folder. Use the SDK for the programming language to retrieve the table name.
  • B. Create a Lambda environment variable to store the table name. Use the standard method for the programming language to retrieve the variable.
  • C. Create a global variable that is outside the handler in the Lambda function to store the table name.
  • D. Create a file to store the table name. Zip the file and upload the file to the Lambda layer. Use the SDK for the programming language to retrieve the table name.

Answer: B

Explanation:
The solution that will meet the requirements most efficiently is to create a Lambda environment variable to store the table name. Use the standard method for the programming language to retrieve the variable. This way, the developer can avoid hard-coding the table name in the Lambda function code and easily change the table name by updating the environment variable. The other options either involve storing the table name in a file, which is less efficient and secure than using an environment variable, or creating a global variable, which is not recommended as it can cause concurrency issues.


NEW QUESTION # 44
A company runs a payment application on Amazon EC2 instances behind an Application Load Balance The EC2 instances run in an Auto Scaling group across multiple Availability Zones The application needs to retrieve application secrets during the application startup and export the secrets as environment variables These secrets must be encrypted at rest and need to be rotated every month.
Which solution will meet these requirements with the LEAST development effort?

  • A. Store the secrets in AWS Secrets Manager Provision a new customer master key Use the key to encrypt the secrets Enable automatic rotation Configure an Amazon EC2 user data script to programmatically retrieve the secrets during the startup and export as environment variables
  • B. Save the secrets in a text file and store the text file in Amazon S3 Provision a customer managed key Use the key for secret encryption in Amazon S3 Read the contents of the text file and read the export as environment variables Configure S3 Object Lambda to rotate the text file every month
  • C. Save the secrets as base64 encoded environment variables in the application properties. Retrieve the secrets during the application startup. Reference the secrets in the application code. Write a script to rotate the secrets saved as environment variables.
  • D. Save the secrets as strings in AWS Systems Manager Parameter Store and use the default AWS Key Management Service (AWS KMS) key Configure an Amazon EC2 user data script to retrieve the secrets during the startup and export as environment variables Configure an AWS Lambda function to rotate the secrets in Parameter Store every month.

Answer: A

Explanation:
Explanation
AWS Secrets Manager is a service that enables the secure management and rotation of secrets, such as database credentials, API keys, or passwords. By using Secrets Manager, the company can avoid hardcoding secrets in the application code or properties files, and instead retrieve them programmatically during the application startup. Secrets Manager also supports automatic rotation of secrets by using AWS Lambda functions or built-in rotation templates. The company can provision a customer master key (CMK) to encrypt the secrets and use the AWS SDK or CLI to export the secrets as environment variables. References:

NEW QUESTION # 45
A developer is creating an application that includes an Amazon API Gateway REST API in the us-east-2 Region. The developer wants to use Amazon CloudFront and a custom domain name for the API. The developer has acquired an SSL/TLS certificate for the domain from a third-party provider.
How should the developer configure the custom domain for the application?

  • A. Import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the us-east-1 Region. Create a DNS CNAME record for the custom domain.
  • B. Import the SSL/TLS certificate into CloudFront. Create a DNS CNAME record for the custom domain.
  • C. Import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the same Region as the API.
    Create a DNS CNAME record for the custom domain.
  • D. Import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the same Region as the API.
    Create a DNS A record for the custom domain.

Answer: A

Explanation:
Explanation
Amazon API Gateway is a service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. Amazon CloudFront is a content delivery network (CDN) service that can improve the performance and security of web applications. The developer can use CloudFront and a custom domain name for the API Gateway REST API. To do so, the developer needs to import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the us-east-1 Region. This is because CloudFront requires certificates from ACM to be in this Region. The developer also needs to create a DNS CNAME record for the custom domain that points to the CloudFront distribution.

NEW QUESTION # 46
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?

  • A. Create an Amazon ElastiCache for Redis instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
  • B. Create an Amazon ElastiCache for Memcached instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
  • C. Create an Amazon RDS for MySQL read replica. Connect to the read replica by using SSL. Configure the read replica to store frequently accessed data.
  • D. Create an Amazon DynamoDB table and a DynamoDB Accelerator (DAX) cluster for the table. Store frequently accessed data in the DynamoDB table.

Answer: A

Explanation:
Amazon ElastiCache is a service that offers fully managed in-memory data stores that are compatible with Redis or Memcached. The developer can create an ElastiCache for Redis instance and enable encryption of data in transit and at rest. This will ensure that the PHI is encrypted at all times. The developer can store frequently accessed data in the cache and use Redis features such as sorting and ranking to enhance the performance of the application.
