   A network operations team needs to continuously monitor interface utilization and error counters across thousands of devices. They want to avoid polling each device every few minutes and instead receive updates only when a value changes. Which model-driven programmability use case directly addresses this requirement?

   • ANetwork telemetry using model-driven streaming
   • BConfiguration management using NETCONF
   • CDevice discovery using CDP/LLDP
   • DCompliance checking using YANG

   A junior engineer is asked to automate a repetitive VLAN configuration task. They propose writing a script that logs into each switch via SSH, runs 'vlan' commands, and parses the output. A senior engineer rejects this approach. Which reason best aligns with the value of model-driven programmability?

   • ACLI scripts are slower than NETCONF
   • BCLI scripts cannot be run on Cisco devices
   • CCLI scripts require a dedicated management server
   • DCLI output is unstructured and varies across platforms, making scripts brittle

   A network admin is asked to explain to management why the team is investing in model-driven programmability. The admin needs to emphasize that it allows the network to be treated as code. Which statement best describes this concept?

   • AAll network commands are written in a programming language like Python
   • BNetwork configuration is represented in structured data models that can be versioned, reviewed, and applied programmatically
   • CThe network can be managed entirely through a graphical dashboard
   • DNetwork devices are automatically replaced by software running on servers
