Amazon AWS Certified Developer - Associate Sample Questions (Q44-Q49):

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. 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
B. 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.
C. 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.
D. 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

Answer: D

Explanation:
* AWS Secrets Manager: Built for managing secrets, providing encryption, automatic rotation, and access control.
* Customer Master Key (CMK): Provides an extra layer of control over encryption through AWS KMS.
* Automatic Rotation: Enhances security by regularly changing the secret.
* User Data Script: Allows secrets retrieval at instance startup and sets them as environment variables for seamless use within the application.

NEW QUESTION # 45
A developer is working on a Python application that runs on Amazon EC2 instances. The developer wants to enable tracing of application requests to debug performance issues in the code.
Which combination of actions should the developer take to achieve this goal? (Choose two.)

A. Install and configure the AWS X-Ray SDK for Python in the application.
B. Configure the application to write trace data to /var/log/xray.
C. Configure the application to write JSON-formatted logs to /var/log/cloudwatch.
D. Install the AWS X-Ray daemon on the EC2 instances.
E. Install the Amazon CloudWatch agent on the EC2 instances.

Answer: A,D

NEW QUESTION # 46
A developer is building a new application that will be deployed on AWS. The developer has created an AWS CodeCommit repository for the application. The developer has initialized a new project for the application by invoking the AWS Cloud Development Kit (AWS CDK) cdk init command.
The developer must write unit tests for the infrastructure as code (IaC) templates that the AWS CDK generates. The developer also must run a validation tool across all constructs in the CDK application to ensure that critical security configurations are activated.
Which combination of actions will meet these requirements with the LEAST development overhead? (Choose two.)

A. Use the CDK Aspects class to create custom rules to apply to the CDK application. Fall the stack synthesis if any violations are present.
B. Use a unit testing framework to write custom unit tests against the cdk.out file that the AWS CDK generates. Run the unit tests in a continuous integration and continuous delivery (CI/CD) pipeline that is invoked after any commit to the repository.
C. Use the CDK runtime context to set key-value pairs that must be present in the cdk.out file that the AWS CDK generates. Fail the stack synthesis if any violations are present.
D. Use the CDK assertions module to integrate unit tests with the application. Run the unit tests in a continuous integration and continuous delivery (CI/CD) pipeline that is invoked after any commit to the repository.
E. Write a script that searches the application for specific key configuration strings. Configure the script to produce a report of any security violations.

Answer: A,D

NEW QUESTION # 47
A developer is writing an application for a company. The application will be deployed on Amazon EC2 and will use an Amazon RDS for Microsoft SQL Server database. The company's security team requires that database credentials are rotated at least weekly.
How should the developer configure the database credentials for this application?

A. Create a database user. Store the user name and password in an AWS Systems Manager Parameter Store secure string parameter. Enable rotation of the AWS Key Management Service (AWS KMS) key that is used to encrypt the parameter.
B. Use the EC2 user data to create a database user. Provide the user name and password in environment variables to the application.
C. Enable IAM authentication for the database. Create a database user for use with IAM authentication. Enable password rotation.
D. Create a database user. Store the user name and password in an AWS Secrets Manager secret that has daily rotation enabled.

Answer: D

Explanation:
Create a database user. Store the user name and password in an AWS Secrets Manager secret that has daily rotation enabled. This will allow the developer to securely store the database credentials and automatically rotate them at least weekly to meet the company's security requirements.

NEW QUESTION # 48
A developer has created an AWS Lambda function that makes queries to an Amazon Aurora MySQL DB instance. When the developer performs a test the OB instance shows an error for too many connections.
Which solution will meet these requirements with the LEAST operational effort?

A. Create a read replica for the DB instance Query the replica DB instance instead of the primary DB instance.
B. Configure the Amazon Aurora MySQL DB instance tor Multi-AZ deployment.
C. Migrate the data lo an Amazon DynamoDB database.
D. Create a proxy in Amazon RDS Proxy Query the proxy instead of the DB instance.

Answer: D

Explanation:
This solution will meet the requirements by using Amazon RDS Proxy, which is a fully managed, highly available database proxy for Amazon RDS that makes applications more scalable, more resilient to database failures, and more secure. The developer can create a proxy in Amazon RDS Proxy, which sits between the application and the DB instance and handles connection management, pooling, and routing. The developer can query the proxy instead of the DB instance, which reduces the number of open connections to the DB instance and avoids errors for too many connections. Option A is not optimal because it will create a read replica for the DB instance, which may not solve the problem of too many connections as read replicas also have connection limits and may incur additional costs. Option B is not optimal because it will migrate the data to an Amazon DynamoDB database, which may introduce additional complexity and overhead for migrating and accessing data from a different database service. Option C is not optimal because it will configure the Amazon Aurora MySQL DB instance for Multi-AZ deployment, which may improve availability and durability of the DB instance but not reduce the number of connections.
