Answer: C, E.
The operational excellence pillar of a well-architected framework has below 5 design principles.
-Perform operations as code.
-Make frequent, small, reversible changes.
-Refine operations procedures frequently.
-Anticipate failure.
-Learn from all operational failures.
The security pillar of a well-architected framework has below 7 design principles.
-Implement a strong identity foundation.
-Enable traceability.
-Apply security at all layers.
-Automate security best practices.
-Protect data in transit and at rest.
-Keep people away from data.
-Prepare for security events.
The reliability pillar of a well-architected framework has below 5 design principles.
-Automatically recover from failure.
-Test recovery procedures.
-Scale horizontally to increase aggregate workload availability.
-Stop guessing capacity.

The AWS Well-Architected Framework is a methodology designed to help cloud architects build secure, efficient, and resilient infrastructure for their applications. The framework is based on five pillars: Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization.
Operational Excellence is one of the five pillars of the AWS Well-Architected Framework. It focuses on ensuring that operations are efficient, reliable, and scalable. The following design principles relate to the Operational Excellence pillar:
B. Enable traceability: This design principle ensures that you can track and monitor changes to your infrastructure and applications. Traceability helps you identify issues quickly and accurately and enables you to roll back changes if necessary. With AWS, you can enable traceability by using services like AWS CloudTrail, AWS Config, and Amazon CloudWatch to monitor and log activity in your environment.
D. Manage change in automation: This design principle encourages you to automate as many operational tasks as possible. By automating tasks such as software deployments and configuration changes, you can reduce the risk of errors and ensure that your infrastructure is consistent and reliable. AWS offers several tools to help you manage change in automation, such as AWS CloudFormation and AWS OpsWorks.
In summary, two design principles that relate to the Operational Excellence pillar of the Well-Architected framework are "Enable traceability" and "Manage change in automation." By enabling traceability and managing change in automation, you can build a more efficient, reliable, and scalable infrastructure for your applications on AWS.
