Amazon AWS Certified Developer - Associate Sample Questions (Q80-Q85):

NEW QUESTION # 80
A company wants to deploy and maintain static websites on AWS. Each website's source code is hosted in one of several version control systems, including AWS CodeCommit, Bitbucket, and GitHub. The company wants to implement phased releases by using development, staging, user acceptance testing, and production environments in the AWS Cloud. Deployments to each environment must be started by code merges on the relevant Git branch. The company wants to use HTTPS for all data exchange. The company needs a solution that does not require servers to run continuously. Which solution will meet these requirements with the LEAST operational overhead?

  • A. Host each website in AWS Elastic Beanstalk with multiple environments. Use the EB CLI to link each repository branch. Integrate AWS CodePipeline to automate deployments from version control code merges.
  • B. Host each website in different Amazon S3 buckets for each environment. Configure AWS CodePipeline to pull source code from version control. Add an AWS CodeBuild stage to copy source code to Amazon S3.
  • C. Host each website by using AWS Amplify with a serverless backend. Conned the repository branches that correspond to each of the desired environments. Start deployments by merging code changes to a desired branch.
  • D. Host each website on its own Amazon EC2 instance. Write a custom deployment script to bundle each website's static assets. Copy the assets to Amazon EC2. Set up a workflow to run the script when code is merged.

Answer: C

Explanation:
AWS Amplify is an all in one service for the requirement.

NEW QUESTION # 81
A developer maintains applications that store several secrets in AWS Secrets Manager. The applications use secrets that have changed over time. The developer needs to identify required secrets that are still in use. The developer does not want to cause any application downtime.
What should the developer do to meet these requirements?

  • A. Configure AWS X-Ray for the applications. Create a sampling rule lo match the GetSecretValue Secrets Manager API operation requests.
  • B. Configure an AWS CloudTrail log file delivery to an Amazon S3 bucket. Create an Amazon CloudWatch alarm for the GetSecretValue. Secrets Manager API operation requests
  • C. Create a secrets manager-secret-unused AWS Config managed rule. Create an Amazon EventBridge rule to Initiate notification when the AWS Config managed rule is met.
  • D. Deactivate the applications secrets and monitor the applications error logs temporarily.

Answer: C

Explanation:
Explanation
This solution will meet the requirements by using AWS Config to monitor and evaluate whether Secrets Manager secrets are unused or have been deleted, based on specified time periods. The secrets manager-secret-unused managed rule is a predefined rule that checks whether Secrets Manager secrets have been rotated within a specified number of days or have been deleted within a specified number of days after last accessed date. The Amazon EventBridge rule will trigger a notification when the AWS Config managed rule is met, alerting the developer about unused secrets that can be removed without causing application downtime. Option A is not optimal because it will use AWS CloudTrail log file delivery to an Amazon S3 bucket, which will incur additional costs and complexity for storing and analyzing log files that may not contain relevant information about secret usage. Option C is not optimal because it will deactivate the application secrets and monitor the application error logs temporarily, which will cause application downtime and potential data loss. Option D is not optimal because it will use AWS X-Ray to trace secret usage, which will introduce additional overhead and latency for instrumenting and sampling requests that may not be related to secret usage.

NEW QUESTION # 82
An IAM role is attached to an Amazon EC2 instance that explicitly denies access to all Amazon S3 API actions. The EC2 instance credentials file specifies the IAM access key and secret access key, which allow full administrative access.
Given that multiple modes of IAM access are present for this EC2 instance, which of the following is correct?

  • A. The EC2 instance will only be able to list the contents of one S3 bucket at a time.
  • B. The EC2 instance will only be able to list the S3 buckets.
  • C. The EC2 instance will be able to perform all actions on any S3 bucket.
  • D. The EC2 instance will not be able to perform any S3 action on any S3 bucket.

Answer: D


NEW QUESTION # 83
A gaming application stores scores for players in an Amazon DynamoDB table that has four attributes: user_id, user_name, user_score, and user_rank. The users are allowed to update their names only. A user is authenticated by web identity federation.
Which set of conditions should be added in the policy attached to the role for the dynamodb:PutItem API call?

  • A. "Condition": {
    "ForAllValues:StringEquals": {
    "dynamodb:LeadingKeys": ["${www.amazon.com:user_name}"],
    "dynamodb:Attributes": ["username", "userid"]
    }
    }
  • B. "Condition": {
    "ForAllValues:StringEquals": {
    "dynamodb:LeadingKeys": ["${www.amazon.com:user_id}"],
    "dynamodb:Attributes": ["user_name"]
    }
    }
  • C. "Condition": {
    "ForAllValues:StringEquals": {
    "dynamodb:LeadingKeys": ["${www.amazon.com:user_id}"],
    "dynamodb:Attributes": ["user_name", "user_id"]
    }
    }
  • D. "Condition": {
    "ForAllValues:StringEquals": {
    "dynamodb:LeadingKeys": ["${www.amazon.com:user_name}"],
    "dynamodb:Attributes": ["user_id"]
    }
    }

Answer: B

Explanation:
The correct policy condition ensures that:
The LeadingKeys condition restricts operations to the authenticated user's user_id.
The Attributes condition limits the updatable attributes to user_name.
Explanation of Choices:
Option A: Correctly enforces both the key restriction (dynamodb:LeadingKeys) and ensures only the user_name attribute can be updated.
Option B, C, D: Use incorrect conditions, such as referencing user_name in the LeadingKeys or including other attributes like user_id in updatable fields.

The developer creates an S3 bucket that has versioning enabled.
What should the developer do next to meet the data retention requirements?

  • A. Create an S3 Lifecycle rule on the S3 bucket. Configure the rule to delete expired object delete markers and permanently delete noncurrent versions 1 year after object creation.
  • B. Create an event notification for all object removal events in the S3 bucket. Configure the event notification to invoke an AWS Lambda function. Program the Lambda function to check the object creation date and to delete the object if the object is older than 1 year.
  • C. Create an event notification for all object creation events in the S3 bucket. Configure the event notification to invoke an AWS Lambda function. Program the Lambda function to check the object creation date and to delete the object if the object is older than 1 year.
  • D. Create an S3 Lifecycle rule on the S3 bucket. Configure the rule to expire current versions of objects and permanently delete noncurrent versions 1 year after object creation.

Answer: D
