To ensure high availability and disaster recovery for the RDS for MySQL database, follow these steps:

Create a Cross-Region Read Replica:

In the RDS console, create a cross-Region read replica of the primary database instance. This read replica will provide high availability and the lowest RTO and RPO in case of a disaster.

Step-by-Step Explanation:

Understand the Problem:

Enforce a policy that requires all AWS resources to be tagged according to company policy.

Continuously identify non-compliant resources.

Analyze the Requirements:

Implement a solution to monitor and enforce resource tagging compliance.

Evaluate the Options:

Option A: AWS CloudTrail.

Provides logging and monitoring of API calls but does not enforce tagging policies.

Option B: Amazon Inspector.

Primarily used for security assessments, not resource tagging compliance.

Option C: AWS Config.

Monitors and evaluates the configurations of AWS resources.

Can enforce compliance by using AWS Config rules to check resource tags.

Option D: AWS Systems Manager.

Provides operational insights and management but is not specifically designed for compliance enforcement.

Select the Best Solution:

Option C: AWS Config is designed for compliance and configuration monitoring, making it the ideal service for enforcing and identifying non-compliant resource tags.

Managing Resource Tag Compliance with AWS Config

AWS Config provides the necessary tools to enforce and monitor resource tagging compliance, ensuring all resources adhere to the set policy.

After increasing the size of an Amazon EBS volume, the operating system must be configured to use the additional space. For a Windows instance, you need to extend the file system using disk management tools.

Open Disk Management:

Connect to your Windows EC2 instance using RDP.

Open the Disk Management tool by right-clicking the Start button and selecting Disk Management.

Extend the Volume:

Locate the EBS volume that was resized.

Right-click on the volume and select Extend Volume.

Follow the Extend Volume Wizard to allocate the newly available space to the file system.

Verify the New Size:

After extending the volume, verify that the file system reflects the increased storage capacity.

Extending a Windows File System After Resizing a Volume

A mount target provides an IP address for an NFSv4 endpoint at which you can mount an Amazon EFS file system. You mount your file system using its Domain Name Service (DNS) name, which resolves to the IP address of the EFS mount target in the same Availability Zone as your EC2 instance. You can create one mount target in each Availability Zone in an AWS Region. If there are multiple subnets in an Availability Zone in your VPC, you create a mount target in one of the subnets. Then all EC2 instances in that Availability Zone share that mount target.
