AWS-CDA Exam Syllabus Topics:

Section	Objectives
Deployment - 22%
Deploy written code in AWS using existing CI/CD pipelines, processes, and patterns.	- Commit code to a repository and invoke build, test and/or deployment actions - Use labels and branches for version and release management - Use AWS CodePipeline to orchestrate workflows against different environments - Apply AWS CodeCommit, AWS CodeBuild, AWS CodePipeline, AWS CodeStar, and AWS CodeDeploy for CI/CD purposes - Perform a roll back plan based on application deployment policy
Deploy applications using AWS Elastic Beanstalk.	- Utilize existing supported environments to define a new application stack - Package the application - Introduce a new application version into the Elastic Beanstalk environment - Utilize a deployment policy to deploy an application version (i.e., all at once, rolling, rolling with batch, immutable) - Validate application health using Elastic Beanstalk dashboard - Use Amazon CloudWatch Logs to instrument application logging
Prepare the application deployment package to be deployed to AWS.	- Manage the dependencies of the code module (like environment variables, config files and static image files) within the package - Outline the package/container directory structure and organize files appropriately - Translate application resource requirements to AWS infrastructure parameters (e.g., memory, cores)
Deploy serverless applications.	- Given a use case, implement and launch an AWS Serverless Application Model (AWS SAM) template - Manage environments in individual AWS services (e.g., Differentiate between Development, Test, and Production in Amazon API Gateway)
Security - 26%
Make authenticated calls to AWS services.	- Communicate required policy based on least privileges required by application. - Assume an IAM role to access a service - Use the software development kit (SDK) credential provider on-premises or in the cloud to access AWS services (local credentials vs. instance roles)
Implement encryption using AWS services.	- Encrypt data at rest (client side; server side; envelope encryption) using AWS services - Encrypt data in transit
Implement application authentication and authorization.	- Add user sign-up and sign-in functionality for applications with Amazon Cognito identity or user pools - Use Amazon Cognito-provided credentials to write code that access AWS services. - Use Amazon Cognito sync to synchronize user profiles and data- Use developer-authenticated identities to interact between end user devices, backend authentication, and Amazon Cognito
Development with AWS Services - 30%
Write code for serverless applications.	- Compare and contrast server-based vs. serverless model (e.g., micro services, stateless nature of serverless applications, scaling serverless applications, and decoupling layers of serverless applications) - Configure AWS Lambda functions by defining environment variables and parameters (e.g., memory, time out, runtime, handler) - Create an API endpoint using Amazon API Gateway - Create and test appropriate API actions like GET, POST using the API endpoint - Apply Amazon DynamoDB concepts (e.g., tables, items, and attributes) - Compute read/write capacity units for Amazon DynamoDB based on application requirements - Associate an AWS Lambda function with an AWS event source (e.g., Amazon API Gateway, Amazon CloudWatch event, Amazon S3 events, Amazon Kinesis) - Invoke an AWS Lambda function synchronously and asynchronously
Translate functional requirements into application design.	- Determine real-time vs. batch processing for a given use case - Determine use of synchronous vs. asynchronous for a given use case - Determine use of event vs. schedule/poll for a given use case - Account for tradeoffs for consistency models in an application design
Implement application design into application code.	- Write code to utilize messaging services (e.g., SQS, SNS) - Use Amazon ElastiCache to create a database cache - Use Amazon DynamoDB to index objects in Amazon S3 - Write a stateless AWS Lambda function - Write a web application with stateless web servers (Externalize state)

Amazon AWS Certified Developer Associate Exam Sample Questions (Q529-Q534):

NEW QUESTION # 529
A deployment package uses the AWS CLI to copy files into any S3 bucket in the account, using access keys stored in environment variables. The package is running on EC2 instances, and the instances have been modified to run with an assumed IAM role and a more restrictive policy that allows access to only one bucket.
After the change, the Developer logs into the host and still has the ability to write into all of the S3 buckets in that account.
What is the MOST likely cause of this situation?

• A. The AWS credential provider looks for instance profile credentials last
• B. An IAM inline policy is being used on the IAM role
• C. An IAM managed policy is being used on the IAM role
• D. The AWS CLI is corrupt and needs to be reinstalled

Answer: A
NEW QUESTION # 530
A company requires objects that are stored in Amazon S3 to be encrypted. The company is currently using server-side encryption with AWS KMS managed encryption keys (SSE-KMS) A developer needs to optimize the cost-effectiveness of the encryption mechanism without negatively affecting performance What should the developed to meet these requirements'?

• A. Use S3 bucket policies to limit the principals who can create objects.
• B. Change the encryption type to customer-provided keys
• C. Use a custom policy to limit the number of AWS KMS calls that are allowed
• D. Configure the S3 bucket to use an S3 Bucket Key for SSE-KMS

Answer: D
NEW QUESTION # 531
A Developer created configuration specifications for an AWS Elastic Beanstalk application in a file named healthcheckurl.yaml in the .ebextensions/directory of their application source bundle. The file contains the
following:

After the application launches, the health check is not being run on the correct path, event though it is valid.
What can be done to correct this configuration file?

• A. Convert the file to JSON format.
• B. Rename the file to a .config extension.
• C. Change the namespace of the option settings to a cusom namespace.
• D. Change the configuration section from options_settings to resources.

Answer: D Explanation:
Reference:
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/ebextensions.html
You can add AWS Elastic Beanstalk configuration files (.ebextensions) to your web application's source code to configure your environment and customize the AWS resources that it contains. Configuration files are YAML- or JSON-formatted documents with a .config file extension that you place in a folder named .ebextensions and deploy in your application source bundle. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/ebextensions.html
NEW QUESTION # 532
