SOA-C02 Exam Dumps : AWS Certified SysOps Administrator - Associate (SOA-C02)

AWS OpsWorks is a configuration management service that provides managed instances of Chef and Puppet. This service is designed to work seamlessly with Chef recipes, making it the most operationally efficient solution for continuing to use existing Chef recipes after migrating applications to AWS.

Creating an OpsWorks Stack:

Open the AWS OpsWorks console at AWS OpsWorks Console.

Create a new stack and select Chef as the configuration management engine.

Adding Layers:

Add layers to the stack that represent different parts of your application. Each layer can have its own set of Chef recipes.

Assign instances to these layers as needed.

Deploying Chef Recipes:

Upload your existing Chef recipes to the OpsWorks stack.

Configure the layers to use these recipes during setup, deployment, and other lifecycle events.

Working with Stacks

To automate the initialization of additional EBS volumes on Windows EC2 instances, the most effective approach is to integrate initialization scripts within the instance so that they execute upon startup:

Configure Initialization Script: Use a Windows PowerShell script (InitializeDisks.ps1) to initialize and format the additional EBS volumes. The script can assign drive letters based on configurations specified in DriveLetterMappingConfig.json.

Automate at Launch: Ensure that the PowerShell script runs automatically upon instance startup. This can be configured through Windows Task Scheduler or by setting it up in the startup folder.

Create a Custom AMI: Once the instance is configured with the script and successfully initializes the disks on startup, create a new AMI from this setup. This AMI can then be used to launch new instances that will automatically initialize their additional EBS volumes with no manual intervention required.

This method leverages native Windows tools and AWS capabilities to automate EBS volume initialization, enhancing operational efficiency without additional external dependencies.

To enable automatic failover for RDS (MySQL in this case), you must configure it as a Multi-AZ deployment.

From Amazon RDS Multi-AZ documentation:

Multi-AZ deployments provide high availability and automatic failover support.

❌ Why other options are incorrect:

A: Changing engine to PostgreSQL does not help with failover.

C: Read replicas are used for scaling reads, not failover.

D: Automated backups help with point-in-time recovery, not failover.
