Select two primary drivers for network automation.

Network automation is driven by the need to manage complex, dynamic networks efficiently. "Increasing reliance on self-diagnostic and self-healing" is a key driver because it reduces manual intervention, minimizes downtime, and improves network resilience by automatically detecting and resolving issues. "Policy-driven provisioning of resources" is another primary driver, as it allows network configurations and services to be deployed consistently and rapidly based on predefined rules, ensuring compliance and accelerating service delivery. "Eliminating training needs" is incorrect; automation changes the nature of training, requiring new skills. "Reducing hardware footprint" is a potential benefit but not a primary driver for automation itself. "Providing a single entry point for resource provisioning" is a characteristic or outcome of effective automation, not a fundamental driver.
