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

To prevent all teams within an AWS Organizations structure from using Amazon DynamoDB while allowing access to other AWS services, the most effective solution is to use a Service Control Policy (SCP). SCPs apply at the organization, organizational unit (OU), or account level and can override individual IAM policies, including the root user's permissions:

B: Create a service control policy (SCP) in the management account to deny all DynamoDB actions. Apply the SCP to the root of the organization. This policy will effectively block DynamoDB actions across all member accounts without affecting the ability to access other AWS services. SCPs are powerful tools for centrally managing permissions in AWS Organizations and can enforce policy compliance across all accounts. Further information on SCPs and their usage can be found in the AWS documentation on Service Control Policies AWS Service Control Policies.

RI discounts apply to accounts in an organization's consolidated billing family depending upon whether RI sharing is turned on or off for the accounts. By default, RI sharing for all accounts in an organization is turned on. The management account of an organization can change this setting by turning off RI sharing for an account. The capacity reservation for an RI applies only to the account the RI was purchased on, no matter whether RI sharing is turned on or off.

To give the application the ability to resolve internal domain names, the SysOps administrator should create an Amazon Route 53 Resolver outbound endpoint and configure it to forward DNS queries to the on-premises DNS server.

Route 53 Resolver Outbound Endpoint:

An outbound endpoint enables DNS queries to be forwarded from AWS resources in a VPC to an on-premises DNS server.

Steps to Implement:

In the Route 53 console, create a new outbound endpoint in the VPC.

Configure the outbound endpoint with the IP address of the on-premises DNS server.

Update the VPC DNS settings to use the Route 53 Resolver.

Creating an Outbound Endpoint

To quickly remediate resources and bring them back into compliance with patch standards, AWS Systems Manager is the appropriate service to use.

Use AWS Systems Manager:

Leverage Systems Manager Patch Manager to automate the process of patching managed instances.

Use Systems Manager State Manager to ensure that resources remain in compliance with the desired configurations.

To allow CloudFormation templates in all accounts within the organization to reference the latest AMI ID:

Parameter Store in Standard Tier: Storing the AMI ID in Systems Manager Parameter Store provides a central and easy-to-update source.

Enable Resource Sharing with Organizations: This allows the parameter to be shared across accounts in the organization.

Resource Share in AWS RAM: AWS Resource Access Manager (RAM) can be used to share the parameter with the entire organization, allowing other accounts to access the AMI ID.

Using the standard tier in Parameter Store is sufficient, and an EventBridge rule with Lambda for updating AMIs would add unnecessary complexity.
