Amazon AWS Certified Developer - Associate Sample Questions (Q125-Q130):

NEW QUESTION # 125
A developer has written the following IAM policy to provide access to an Amazon S3 bucket:

Which access does the policy allow regarding the s3:GetObject and s3:PutObject actions?

  • A. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket except on objects that start with
    "secrets"
  • B. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket along with access to all S3 actions for objects in the "DOC-EXAMPLE-BUCKET" bucket that start with "secrets"
  • C. Access on all buckets that start with "DOC-EXAMPLE-BUCKET" except the
    "DOC-EXAMPLE-BUCKET/secrets" bucket
  • D. Access on all buckets except the "DOC-EXAMPLE-BUCKET" bucket

Answer: A

Explanation:
Explanation
The IAM policy shown in the image is a resource-based policy that grants or denies access to an S3 bucket based on certain conditions. The first statement allows access to any S3 action on any object in the
"DOC-EXAMPLE-BUCKET" bucket when the request is made over HTTPS (the value of aws:SecureTransport is true). The second statement denies access to the s3:GetObject and s3:PutObject actions on any object in the "DOC-EXAMPLE-BUCKET/secrets" prefix when the request is made over HTTP (the value of aws:SecureTransport is false). Therefore, the policy allows access on all objects in the
"DOC-EXAMPLE-BUCKET" bucket except on objects that start with "secrets". Reference: Using IAM policies for Amazon S3


NEW QUESTION # 126
A company introduced a new feature that should be accessible to only a specific group of premium customers. A developer needs the ability to turn the feature on and off in response to performance and feedback. The developer needs a solution to validate and deploy these configurations quickly without causing any disruptions.
What should the developer do to meet these requirements?

  • A. Use AWS Config to manage the feature configuration and validation. Set up AWS Config rules to turn the feature on and off based on predefined conditions.
  • B. Use AWS Secrets Manager to securely manage and validate the feature configurations. Enable lifecycle rules to turn the feature on and off.
  • C. Use AWS AppConfig to manage the feature configuration and to validate and deploy changes.
    Use feature flags to turn the feature on and off.
  • D. Use AWS Systems Manager Parameter Store to store and validate the configuration settings for the feature. Enable lifecycle rules to turn the feature on and off.

Answer: C


NEW QUESTION # 127
A company requires that all applications running on Amazon EC2 use 1AM roles to gam access to AWS services. A developer is modifying an application that currently relies on 1AM user access keys stored in environment variables to access Amazon DynamoDB tables using boto, the AWS SDK for Python.
The developer associated a role with the same permissions as the 1AM user to the EC2 instance, then deleted the 1AM user. When the application was restarted, the AWS Access Denied Exception messages started appearing in the application logs. The developer was able to use their personal account on the server to run DynamoDB API commands using the AWS CLI.
What is the MOST likely cause of the exception?

  • A. 1AM policies might take a few minutes to propagate to resources.
  • B. The AWS SDK does not support credentials obtained using an instance role.
  • C. Disabled environment variable credentials are still being used by the application.
  • D. The instance's security group does not allow access to http://169.254.169.254.

Answer: C


NEW QUESTION # 128
A developer is working on a serverless application that needs to process any changes to an Amazon DynamoDB table with an AWS Lambda function.
How should the developer configure the Lambda function to detect changes to the DynamoDB table?

  • A. Enable DynamoDB Streams on the table. Create a trigger to connect the DynamoDB stream to the Lambda function.
  • B. Create an Amazon EventBridge rule to invoke the Lambda function on a regular schedule. Conned to the DynamoDB table from the Lambda function to detect changes.
  • C. Create an Amazon Kinesis data stream, and attach it to the DynamoDB table. Create a trigger to connect the data stream to the Lambda function.
  • D. Create an Amazon Kinesis Data Firehose delivery stream, and attach it to the DynamoDB table.
    Configure the delivery stream destination as the Lambda function.

Answer: A

Explanation:
Explanation
Amazon DynamoDB is a fully managed NoSQL database service that provides fast and consistent performance with seamless scalability. DynamoDB Streams is a feature that captures data modification events in DynamoDB tables. The developer can enable DynamoDB Streams on the table and create a trigger to connect the DynamoDB stream to the Lambda function. This solution will enable the Lambda function to detect changes to the DynamoDB table in near real time.

NEW QUESTION # 129
A developer is preparing to deploy an AWS CloudFormation stack for an application from a template that includes an IAM user.
The developer needs to configure the application's resources to retain the IAM user after successful creation.
However, the developer also needs to configure the application to delete the IAM user if the stack rolls back.

  • A. Update CloudFormation template with the following deletion policy:
    AWSTemplateFormatVersion: '2010-09-09'
    Resources:
    appUser:
    Type: AWS::IAM::User
    DeletionPolicy: RetainExceptOnCreate
  • B. Update the CloudFormation service role to include the following policy:
    {
    "Version": "2012-10-17",
    "Statement": [{
    "Effect": "Allow",
    "Action": ["cloudformation:UpdateTerminationProtection"],
    "Resource": "*"
    }]
    }
  • C. Update CloudFormation template with the following deletion policy:
    AWSTemplateFormatVersion: '2010-05-09'
    Resources:
    appUser:
    Type: AWS::IAM::User
    DeletionPolicy: Retain
  • D. Update the stack policy to include the following statements:
    {
    "Statement": [{
    "Effect": "Deny",
    "Action": "Update:*",
    "Principal": "*",
    "Resource": "*",
    "Condition": {
    "StringEquals": {
    "ResourceType": "AWS::IAM::User"
    }
    }
    }]
    }

Answer: A

Explanation:
Comprehensive Detailed Explanation with all AWS References
* Why Option B is Correct:The RetainExceptOnCreate deletion policy ensures that the IAM user is retained after successful stack creation but is deleted if the stack creation fails or rolls back. This meets both requirements.
* Why Other Options are Incorrect:
* Option A: The Retain policy retains the resource regardless of stack status and does not delete the IAM user upon rollback.
* Option C: Updating the service role for termination protection does not address the specific deletion behavior for the IAM user.
* Option D: Stack policy controls updates, not resource deletion behavior during rollbacks.
* AWS Documentation References:
* CloudFormation DeletionPolicy Attribute
