Amazon AWS Certified Developer - Associate Sample Questions (Q425-Q430):

NEW QUESTION # 425
When a developer tries to run an AWS Code Build project, it raises an error because the length of all environment variables exceeds the limit for the combined maximum of characters.
What is the recommended solution?

A. Add the export LC-_ALL" on _ US, tuft" command to the pre _ build section to ensure POSIX Localization.
B. Use AWS Systems Manager Parameter Store to store large numbers ot environment variables
C. Use Amazon Cognate to store key-value pairs for large numbers of environment variables
D. Update the settings for the build project to use an Amazon S3 bucket for large numbers of environment variables

Answer: B

Explanation:
Explanation
This solution allows the developer to overcome the limit for the combined maximum of characters for environment variables in AWS CodeBuild. AWS Systems Manager Parameter Store provides secure, hierarchical storage for configuration data management and secrets management. The developer can store large numbers of environment variables as parameters in Parameter Store and reference them in the buildspec file using parameter references. Adding export LC_ALL="en_US.utf8" command to the pre_build section will not affect the environment variables limit. Using Amazon Cognito or an Amazon S3 bucket to store key-value pairs for environment variables will require additional configuration and integration.

NEW QUESTION # 426
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?

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

Answer: D

Explanation:
To solve this problem, the developer should redeploy the Lambda function in the same subnet as the RDS instance and ensure that the RDS security group allows traffic from the Lambda function. This will allow the Lambda function to access the RDS database within the private subnet of VPC-A. The developer should also make sure that the Lambda function is configured with the appropriate network settings and permissions to access resources within the VPC.

NEW QUESTION # 427
A developer is creating a web application. The developer needs to store, retrieve, and rotate database credentials, OAuth tokens, and API keys.
The credentials, OAuth tokens, and API keys must be stored securely as secrets and must not be hardcoded in the application source code. The secrets must be automatically rotated every 6 months.
What should the developer do to meet these requirements?

A. Create and store the secrets in AWS Secrets Manager. Choose the appropriate secret type. Turn on automatic rotation. Set the rotation schedule to every 6 months.
B. Create and store the secrets in Amazon EventBridge. Configure a RotateKey event in EventBridge to rotate the secrets every 6 months.
C. Create and store the secrets in AWS KMS. Configure AWS KMS to automatically rotate the secrets every 6 months.
D. Create and store the secrets in AWS Certificate Manager (ACM). Choose the appropriate certificate type. Set up the rotation period of the certificate to be every 6 months.

Answer: A

Explanation:
AWS best practice is to store sensitive values like database passwords, OAuth tokens, and API keys in a dedicated secrets service rather than in source code or configuration files. AWS Secrets Manager is specifically designed for this use case: secure storage, retrieval through APIs/SDKs, fine-grained IAM access control, encryption at rest, auditing through CloudTrail, and-critically-built-in secret rotation.
AWS documentation describes Secrets Manager rotation as an automated process that uses a rotation schedule and typically invokes a Lambda function to update the secret in both Secrets Manager and the target system (for example, a database). The rotation schedule can be configured to a custom interval, including every 6 months, satisfying the requirement.
Option A is incorrect because AWS KMS manages encryption keys, not application secrets. KMS key rotation rotates KMS keys, not database credentials or API tokens.
Option B is incorrect because ACM manages TLS certificates, not arbitrary secrets like API keys and OAuth tokens.
Option C is incorrect because EventBridge can schedule events, but it is not a secrets storage service and does not provide secure secret lifecycle management and integrated rotation workflows by itself.
Therefore, storing secrets in AWS Secrets Manager and enabling automatic rotation with a 6-month schedule is the correct solution.

NEW QUESTION # 428
A developer maintains an Amazon API Gateway REST API. Customers use the API through a frontend UI and Amazon Cognito authentication.
The developer has a new version of the API that contains new endpoints and backward-incompatible interface changes. The developer needs to provide beta access to other developers on the team without affecting customers.
Which solution will meet these requirements with the LEAST operational overhead?

A. Specify new API Gateway endpoints for the API endpoints that the developer wants to add.
B. Define a development stage on the API Gateway API. Instruct the other developers to point the endpoints to the development stage.
C. Define a new API Gateway API that points to the new API application code. Instruct the other developers to point the endpoints to the new API.
D. Implement a query parameter in the API application code that determines which code version to call.

Answer: B

Explanation:
Amazon API Gateway is a service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. The developer can define a development stage on the API Gateway API and instruct the other developers to point the endpoints to the development stage. This way, the developer can provide beta access to the new version of the API without affecting customers who use the production stage. This solution will meet the requirements with the least operational overhead.

NEW QUESTION # 429
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. Create a Lambda environment variable to store the table name. Use the standard method for the programming language to retrieve the variable.
B. Create a global variable that is outside the handler in the Lambda function to store the table name.
C. 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.
D. 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.

Answer: A

Explanation:
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.
