   What is a characteristic of RPC APIs compared to REST APIs?

   • AAuthentication is done over provisions for the service caller and vice versa for RPC API, and REST API uses HTTP headers for authentication.
   • BAll communications between the client and server must be stateless for RPC API, and REST API is stateful.
   • CThe architecture model for RPC API is resource-focused, and REST API is procedure-focused.
   • DThe data payload must be in JSON format for RPC API, and REST API allows JSON and XML formats.

   What is the first development task in test-driven development?

   • AWrite code that implements a desired function.
   • BWrite a failing test case for a desired function.
   • CReverse engineer the code for a desired function.
   • DWrite a passing test case for existing code.

   Show answer

   Answer: B

   Explanation

   Actually, I have re-read the question and I agree it is B. Write a failing test case for a DESIRED Function. i.e. the function hasn't been written yet and therefore the code would fail. It makes sense and fits the TDD defintion.

   • CEnvironments must be provisioned consistently using the same inputs.
   • DService overlap is encouraged to cater for unique environment needs.
   • EComplete complex systems must be able to be built from reusable infrastructure definitions.

    An engineer deploys a Cisco CSR 1000 V instance to a virtual machine. The engineer must output the device configuration in JSON format. Which protocol is used for this task?

    • AYANG
    • BNETCONF
    • CSNMP
    • DRESTCONF

    Show answer

    Answer: D

    Explanation

    RESTCONF is a protocol for remotely accessing and modifying data defined in a data model. It is used to transfer data in JSON or XML format over HTTP. RESTCONF can be used to output device configuration in JSON format on a Cisco CSR 1000V instance. YANG is a data modeling language used to define data for network management. NETCONF is a network management protocol used to install, manipulate, and delete configuration data on network devices. SNMP (Simple Network Management Protocol) is a protocol used to monitor and manage network devices.
