   Select 2

   What are two benefits of model-driven programmability? (Choose two.)

   • Aeasier to design, deploy, and manage APIs
   • Bsingle choice of transport, protocol, and encoding
   • Cmodels decoupled from transport, protocol, and encoding
   • Dmodel-based, structured, and human friendly
   • Emodel-driven APIs for abstraction and simplification

   Show answer

   Answer: CE

   Explanation

   C and E are correct. Model-Driven Programmability provides: - Configuration language that is human-readable - Model-based, structured, and computer-friendly - Include support for multiple model types, including native, OpenConfig, and IETF - The specification is decoupled from transport, protocol end encoding. - Use model-driven APIs for abstraction and simplification. - Leverage open-source and enjoy wide support

6. Question 36 · 530 in bank

   What is a benefit of model-driven programmability?

   • AIt provides a programmatic and standards-based way of writing configurations to any network device.
   • BBy modeling data, it ensures that vast quantities of data are usable for monitoring.
   • CIt simplifies management and operations by decoupling the networking hardware from its control mechanism.
   • DIt addresses the static architecture of traditional networks being decentralized and complex.

   Show answer

   Answer: A

   Explanation

   Traditionally CLIs or SDK library functions are used to configure network devices. CLIs and scripts are almost always device-specific; they can only be used in the same type of devices that use the same CLis from the same vendor. Moreover, those functions may not exist for all configuration commands, and where they do exist, it may be difficult to program a complex configuration. So, the correct answer is A since the model-driven programming provides a standard way to describe the desired configuration of the network devices. Of course, the target device itself has to support the ability to use model-driven configuration.

9. Question 39 · 530 in bank

   Refer to the exhibit.

   

   The definition of the YANG module and a RESTCONF query sent to a Cisco IOS XE device is shown. Why does the RESTCONF interface respond with a 204 status code?

   • AThe query retrieved the logging severity level.
   • BThe query updated the logging severity level or created it if not present on the device.
   • CThe query failed at retrieving the logging severity level.
   • DThe query failed to set the logging severity level due to an invalid path.

10. Question 40 · 530 in bank

    What is a requirement when authenticating a RESTCONF API session with a router that runs Cisco IOS XE Software?

    • ANo authentication is required.
    • BOAuth must be used.
    • CA token must be retrieved and the associated string must be embedded in the X-Auth-Token header.
    • DBasic authentication must be used.

    Show answer

    Answer: D

    Explanation

    D. From the book: "Authentication is accomplished using typical HTTP authentication models, such as basic authentication, where usernames and passwords are Base64 encoded and transmitted from the client to the server via an Authentication header"
