   A managed service provider (MSP) is designing an automation solution to manage multiple customer networks. Each customer has different device vendors and configuration requirements. The MSP wants to use a single platform to manage all customers. Which design approach is most effective?

   • ACreate a separate management system for each customer to avoid any cross-contamination.
   • BUse a single set of scripts that assume all devices are from the same vendor.
   • CUse a multi-tenant orchestration platform that supports multiple device vendors through standard APIs and YANG models, with tenant-specific policies.
   • DProvide customers with direct access to the MSP's internal network management system.

   An enterprise network team is adopting CI/CD for network changes. They currently use a monolithic Python script that pushes configs to all devices via SSH. The team wants to introduce version control, automated testing, and staged rollouts. Which design change is most critical to enable this evolution?

   • AOutsource the configuration process to a managed service provider to handle all changes externally.
   • BMove all configuration changes to a single, centralized CLI session to reduce the number of touchpoints.
   • CReplace the monolithic script with a modular pipeline that uses infrastructure-as-code (e.g., Ansible playbooks) and stores configs in Git with peer review.
   • DIncrease the frequency of the existing script's execution to daily and add more logging to capture failures.
