Amazon SAP-C02 Exam Actual Questions

Identify Proxy EC2 Instances:

Determine which EC2 instances in the private subnets are running the proxy server software.

Disable Source/Destination Checks:

For each of these EC2 instances, go to the AWS Management Console.

Navigate to the EC2 dashboard, select the instance, and choose 'Actions' > 'Networking' > 'Change Source/Dest. Check'.

Disable the source/destination check for these instances.

Disabling source/destination checks allows the EC2 instances to route traffic appropriately, enabling them to function as network appliances or proxies. This ensures that traffic from other instances in the private subnets can be routed through the proxy instances to the internet, meeting the company's security requirements.

Enable AWS Security Hub:

Navigate to the AWS Security Hub console in your management account and enable Security Hub. This process integrates Security Hub with AWS Control Tower, allowing you to manage and monitor security findings across all accounts within your organization.

Designate a Delegated Administrator:

In AWS Organizations, designate one of the AWS accounts as the delegated administrator for Security Hub. This account will have the responsibility to manage and oversee the security posture of all accounts within the organization.

Deploy Controls Across Accounts:

Use AWS Security Hub to automatically enable security controls across all AWS accounts in the organization. This provides a centralized view of the security state of all accounts and ensures continuous monitoring and compliance.

Utilize AWS Security Hub Features:

Leverage the capabilities of Security Hub to aggregate security alerts, run continuous security checks, and generate findings based on the AWS Foundational Security Best Practices. Security Hub integrates with other AWS services like AWS Config, Amazon GuardDuty, and AWS IAM Access Analyzer to enhance security monitoring and remediation.

By integrating AWS Security Hub with AWS Control Tower and using a delegated administrator account, you can achieve a centralized and comprehensive view of your organization's security posture, facilitating effective management and remediation of security issues.

Create a Transit Gateway:

Step 1: In the AWS Management Console, navigate to the VPC Dashboard.

Step 2: Select 'Transit Gateways' and click on 'Create Transit Gateway'.

Step 3: Configure the transit gateway by providing a name and setting the options for Amazon side ASN and VPN ECMP support as needed.

Step 4: Attach each of the company's VPCs and relevant subnets to the transit gateway. This centralizes the network management and simplifies the routing configurations, supporting scalable and flexible network architecture.

Set Up AWS PrivateLink:

Step 1: Create a Network Load Balancer (NLB) in the management VPC that points to the compute resource responsible for license validation.

Step 2: Create an AWS PrivateLink endpoint service pointing to this NLB.

Step 3: Allow each customer's VPC to create an interface endpoint to this PrivateLink service. This setup enables secure and private communication between the customer VPCs and the management VPC, ensuring one-way access from each customer's VPC to the management VPC for license validation.

This combination leverages the benefits of AWS Transit Gateway for scalable and centralized routing, and AWS PrivateLink for secure and private service access, meeting the requirement with minimal operational overhead.

Store the PGP Private Key:

Step 1: In the AWS Management Console, navigate to AWS Secrets Manager.

Step 2: Store the PGP private key in Secrets Manager. Ensure the key is encrypted and properly secured.

Set Up the Transfer Family Managed Workflow:

Step 1: In the AWS Transfer Family console, create a new managed workflow.

Step 2: Add a nominal step to the workflow that includes the decryption of the files. Configure this step with the PGP decryption parameters, referencing the PGP private key stored in Secrets Manager.

Step 3: Associate this workflow with the Transfer Family SFTP server, ensuring that incoming files are automatically decrypted upon receipt.

This solution ensures that the data is securely decrypted as it is transferred from the SFTP server to the S3 bucket, automating the decryption process and leveraging AWS Secrets Manager for key management.

Set Up EventBridge Event Bus:

Step 1: Open the Amazon EventBridge console and create a custom event bus. This bus will be used to handle user deletion events.

Step 2: Name the event bus appropriately (e.g., user-deletion-bus).

Post Events on User Deletion:

Step 1: Modify the central user service to post an event to the custom EventBridge event bus whenever a user is deleted.

Step 2: Ensure the event includes relevant details such as the user ID and any other necessary metadata.

Create EventBridge Rules for Microservices:

Step 1: For each microservice that needs to delete user data, create a new rule in EventBridge that triggers on the user deletion event.

Step 2: Define the event pattern to match the user deletion event. This pattern should include the event details posted by the central user service.

Invoke Microservice Logic:

Step 1: Configure the EventBridge rule to invoke a target, such as an AWS Lambda function, which contains the logic to delete the user data from the microservice's data store.

Step 2: Each microservice should have its Lambda function or equivalent logic to handle the deletion of user data upon receiving the event.

Using Amazon EventBridge ensures a scalable, reliable, and decoupled approach to handle the deletion of user data across multiple microservices. This setup allows each microservice to independently process user deletion events without direct dependencies on other services.
