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

AWS Systems Manager Run Command provides an efficient method to execute administrative tasks on EC2 instances. This solution will minimize the time and complexity involved:

Select Document: Choose AWS-RunShellScript for Linux-based instances or AWS-RunPowerShellScript for Windows-based instances.

Configure Command: Enter the mitigation script provided by the security team into the command document.

Target Instances: Use the tagging system to target only the instances that match the specific OS as identified by their tags.

Execute Command: Run the command across the targeted instances.

Verification and Reporting: The command history in Systems Manager will serve as evidence of execution and success, which can be reported back to the security team.

AWS Documentation Reference:More about Run Command can be found here: AWS Systems Manager Run Command.

To reduce the time required for new instances to become available in an Auto Scaling group, pre-installing the necessary software in the AMI used by the Auto Scaling group is the most effective solution.

Use EC2 Image Builder:

Utilize EC2 Image Builder to create a custom AMI that includes all the required software and configurations.

This reduces the setup time during instance launch, as the user data script will no longer need to install the software.

To restrict access to an application based on geographic location (France in this case), the appropriate routing policy in Amazon Route 53 is geolocation routing. This policy allows you to specify traffic routing based on the geographic location of your users:

B: Use a geolocation routing policy. Select France as the location in the record. This ensures that only DNS queries originating from France are routed to the application, fulfilling the requirement to limit access to users within France initially. More information about setting up geolocation routing can be found in the AWS Route 53 documentation on geolocation routing Amazon Route 53 Geolocation Routing.

DependsOn Attribute in CloudFormation:

The DependsOn attribute in AWS CloudFormation ensures that one resource is created only after another resource has been successfully created. In this case, it ensures that the EC2 instance is fully launched before the custom resource (the Lambda function) is executed.

Steps:

Update the CloudFormation template to include the DependsOn attribute for the custom resource.

Ensure that the custom resource references the EC2 instance.

Resources:

MyEC2Instance:

Type: AWS::EC2::Instance

Properties:

# EC2 properties

MyCustomResource:

Type: Custom::MyCustomResource

DependsOn: MyEC2Instance

Properties:

ServiceToken: !GetAtt MyLambdaFunction.Arn

# Other properties

To manage incomplete multipart uploads in an Amazon S3 bucket, creating an S3 Lifecycle rule to specifically address these uploads is the most effective method. The rule can be configured to automatically delete expired multipart upload parts, which helps in cleaning up unused data and reducing storage costs. Option A is correct as it directly addresses the requirement to manage incomplete uploads effectively. Reference on setting up S3 Lifecycle policies can be found here Amazon S3 Lifecycle.

To control access to Amazon EC2 instances using AWS Systems Manager Session Manager based on specific tags:

Attach an IAM Policy to Users or Groups: Create and attach an Identity and Access Management (IAM) policy to the IAM users or groups who need access to the EC2 instances. This policy should specify the permissions required to use Session Manager to start sessions with the instances.

Create an IAM Policy with Tag-Based Conditions: Create an IAM policy that includes a condition element to allow access to EC2 instances based on specific tags. This policy can be designed to grant the ssm:StartSession permission only for instances that match certain tags, as defined in the condition block of the IAM policy. Here is a sample condition block that could be used:

"Condition": {

"StringEquals": {

"ec2:ResourceTag/YourTagName": "YourTagValue"

}

}

This ensures that only authorized users can initiate sessions with instances that have the specified tags, enhancing security and operational management.

By implementing these policies, you ensure that only the appropriate personnel have the controlled access required, based on the specific business needs and security guidelines.
