   A network team is automating the rollout of a new ACL on 1,000 routers. They have a very short maintenance window and need to ensure that if the ACL is applied on some routers but fails on others, the entire rollout is rolled back. Which model-driven programmability feature is essential?

   • ASNMP trap notifications
   • BTFTP configuration backup
   • CHigh-speed CLI scripting
   • DTransactional configuration with rollback

   Compared to CLI-based management, what does model-driven programmability offer that is especially valuable for automation?

   • AA guarantee that all devices will have identical configurations.
   • BA standardized way to represent configuration and state that is consistent across devices.
   • CA way to bypass network security policies.
   • DA faster typing speed for engineers because commands are shorter.

   An organization is planning to automate the rollout of a new security policy to 500 firewalls. The team wants to minimize the chance of human error and ensure that the policy is applied identically on every device. Which benefit of model-driven programmability is most directly relevant?

   • AIncreased bandwidth on the management network
   • BSimplified troubleshooting of physical layer issues
   • CAutomatic firmware upgrades
   • DReduced errors through standardized, validated configuration

   What is the primary characteristic of model-driven programmability in network automation?

   • AIt uses standardized data models to represent network configuration and state, enabling automation tools to interact with devices in a consistent way.
   • BIt is limited to read-only operations and cannot be used to modify device configuration.
   • CIt relies on screen scraping of CLI output to extract configuration data.
   • DIt requires the use of a specific vendor's proprietary API for all network device interactions.

   A large enterprise is automating network changes. They currently use a mix of CLI scripts and manual processes. The team wants to reduce the risk of configuration drift and improve auditability. They also need to support multiple vendors. The team is considering moving to model-driven programmability. Which factor is most important to ensure success?

   • ARelying on SNMP for all configuration changes
   • BDeploying a single-vendor network
   • CUsing the same CLI commands on all vendors
   • DAdopting a common YANG model set across all vendors
