Amazon AWS Certified Developer - Associate Sample Questions (Q268-Q273):

NEW QUESTION # 268
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 global variable that is outside the handler in the Lambda function to store the table name.
  • B. 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.
  • C. Create a Lambda environment variable to store the table name. Use the standard method for the programming language to retrieve the variable.
  • 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: B


NEW QUESTION # 269
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 S3 buckets.
  • B. The EC2 instance will not be able to perform any S3 action on any S3 bucket.
  • C. The EC2 instance will only be able to list the contents of one S3 bucket at a time.
  • D. The EC2 instance will be able to perform all actions on any S3 bucket.

Answer: B


NEW QUESTION # 270
A developer is creating a template that uses AWS CloudFormation to deploy an application. The application is serverless and uses Amazon API Gateway, Amazon DynamoDB, and AWS Lambda.
Which AWS service or tool should the developer use to define serverless resources in YAML?

  • A. AWS Serverless Application Model (AWS SAM)
  • B. CloudFormation serverless intrinsic functions
  • C. AWS Elastic Beanstalk
  • D. AWS Cloud Development Kit (AWS CDK)

Answer: A

Explanation:
AWS Serverless Application Model (AWS SAM) is an open-source framework that enables developers to build and deploy serverless applications on AWS. AWS SAM uses a template specification that extends AWS CloudFormation to simplify the definition of serverless resources such as API Gateway, DynamoDB, and Lambda. The developer can use AWS SAM to define serverless resources in YAML and deploy them using the AWS SAM CLI.


NEW QUESTION # 271
A developer is migrating some features from a legacy monolithic application to use AWS Lambda functions instead. The application currently stores data in an Amazon Aurora DB cluster that runs in private subnets in a VPC. The AWS account has one VPC deployed. The Lambda functions and the DB cluster are deployed in the same AWS Region in the same AWS account.
The developer needs to ensure that the Lambda functions can securely access the DB cluster without crossing the public internet.
Which solution will meet these requirements?

  • A. Configure the VPC, subnets, and a security group for the Lambda functions.
  • B. Configure the DB cluster's public access setting to Yes.
  • C. Configure a NAT gateway and a security group for the Lambda functions.
  • D. Configure an Amazon RDS database proxy for the Lambda functions.

Answer: A

Explanation:
This solution will meet the requirements by allowing the Lambda functions to access the DB cluster securely within the same VPC without crossing the public internet. The developer can configure a VPC endpoint for RDS in a private subnet and assign it to the Lambda functions. The developer can also configure a security group forthe Lambda functions that allows inbound traffic from the DB cluster on port 3306 (MySQL).
Option A is not optimal because it will expose the DB cluster to public access, which may compromise its security and data integrity. Option B is not optimal because it will introduce additional latency and complexity to use an RDS database proxy for accessing the DB cluster from Lambda functions within the same VPC. Option C is not optimal because it will require additional costs and configuration to use a NAT gateway for accessing resources in private subnets from Lambda functions.


NEW QUESTION # 272
A company has a multi-node Windows legacy application that runs on premises. The application uses a network shared folder as a centralized configuration repository to store configuration files in .xml format. The company is migrating the application to Amazon EC2 instances. As part of the migration to AWS, a developer must identify a solution that provides high availability for the repository.
Which solution will meet this requirement MOST cost-effectively?

  • A. Mount an Amazon Elastic Block Store (Amazon EBS) volume onto one of the EC2 instances. Deploy a file system on the EBS volume. Use the host operating system to share a folder. Update the application code to read and write configuration files from the shared folder.
  • B. Deploy a micro EC2 instance with an instance store volume. Use the host operating system to share a folder. Update the application code to read and write configuration files from the shared folder.
  • C. Create an Amazon S3 bucket to host the repository. Migrate the existing .xml files to the S3 bucket.
    Update the application code to use the AWS SDK to read and write configuration files from Amazon S3.
  • D. Create an Amazon S3 bucket to host the repository. Migrate the existing .xml files to the S3 bucket.
    Mount the S3 bucket to the EC2 instances as a local volume. Update the application code to read and write configuration files from the disk.

Answer: C

Explanation:
Amazon S3 is a service that provides highly scalable, durable, and secure object storage. The developer can create an S3 bucket to host the repository and migrate the existing .xml files to the S3 bucket. The developer can update the application code to use the AWS SDK to read and write configuration files from S3. This solution will meet the requirement of high availability for the repository in a cost-effective way.
