Free Sample Question 1 out of 3:
The microservices team needs to implement automated canary testing for their Lambda-based application using AWS SAM to ensure new updates are stable before full deployment. Which combination of steps will meet these requirements in the MOST operationally efficient way? (Choose two.)
A. Use AWS SAM CLI commands in AWS CodeDeploy to invoke the Lambda functions to test the deployment.
B.Declare the EventInvokeConfig on the Lambda functions in the AWS SAM templates with OnSuccess and OnFailure configurations.
C. Enable gradual deployments through AWS SAM templates.
D. Set the deployment preference type to Canary10Percent30Minutes. Use hooks to test the deployment.
E. Set the deployment preference type to Linear10PercentEvery10Minutes. Use hooks to test the deployment.
Correct Answer: D and E
Explanation:
Options D and E are correct because they enable gradual deployments and canary testing, which are crucial for testing new Lambda function updates with a small percentage of traffic before a full deployment. Gradual deployments through AWS SAM templates (D) and setting the deployment preference to Canary10Percent30Minutes with hooks (E) allow for controlled testing and validation. Gradual Deployments (D): Enables controlled rollout of updates. Canary Deployment (E): Tests new versions with a small percentage of traffic. Hooks: Automate testing during deployment.
Free Sample Question 2 out of 3:
We're deploying a two-tier application with RDS using CloudFormation and need a solution for automatic database password generation and rotation without application modifications. What is the MOST operationally efficient solution that meets these requirements?
A. Use an AWS Lambda function as a CloudFormation custom resource to generate and rotate the password.
B. Use an AWS Systems Manager Parameter Store resource with the SecureString data type to generate and rotate the password.
C. Use a cron daemon on the application's host to generate and rotate the password.
D. Use an AWS Secrets Manager resource to generate and rotate the password.
Correct Answer: D
Explanation:
Option D, using AWS Secrets Manager, is the most operationally efficient solution. Secrets Manager is specifically designed to manage secrets, including generating random passwords during deployment and automatically rotating them without application changes. Option A requires a custom Lambda function, increasing operational overhead. Option B, Parameter Store, is designed for configuration data, not secrets rotation. Option C, a cron daemon, involves managing infrastructure on the application host, adding unnecessary complexity and is not a managed service.
Free Sample Question 3 out of 3:
The engineering team at WebScale Inc. requires a deployment strategy for their Elastic Beanstalk managed web applications that ensures configuration updates are applied exclusively to newly provisioned EC2 instances. Which types of deployment can the developer use to meet this requirement? (Choose two.)
A. All at once
B. Immutable
C. Rolling
D. Blue/green
E. Rolling with additional batch
Correct Answer: B and D
Explanation:
Option B (Immutable) and Option D (Blue/green) are correct because they both deploy changes to entirely new sets of EC2 instances. Immutable deployments replace the entire environment with new instances, ensuring that configuration changes are applied to fresh instances. Blue/green deployments create a completely separate environment with the new configuration, and then switch traffic to it, also ensuring that changes are applied to new instances. Option A (All at once), Option C (Rolling), and Option E (Rolling with additional batch) all involve updating existing instances, which does not meet the requirement of deploying changes to new instances only.
