Write a Python script to construct a NETCONF message using the ncclient library and configure the system time of the device by calling the API in which of the following options?

Options

• AIntent API
• BWeb Services API
• CAtomic APIs
• DBusiness APIs

• C

• D

Explanation

Atomic APIs (C) are the correct choice because NETCONF, used via ncclient, operates at the device level to perform discrete, granular configuration operations - such as setting system time - in a single, targeted transaction. These are called "atomic" because each call configures one specific function and either fully succeeds or fully fails, which is exactly how NETCONF's <edit-config> RPC behaves.

Intent API (A) is wrong because Intent APIs are high-level, business-logic-driven APIs (common in platforms like Cisco DNA Center) that express what you want the network to do, not how to configure a specific device parameter via a protocol like NETCONF.

Web Services API (B) is wrong because this refers broadly to REST/SOAP-based HTTP APIs - a different transport and paradigm from NETCONF, which operates over SSH using XML-encoded RPCs.

Business APIs (D) is wrong because Business APIs operate at the highest abstraction layer, focused on organizational outcomes, not protocol-level device configuration.

Memory tip: Think Atomic = Action on one thing. NETCONF/ncclient makes a precise, one-shot change (like setting the clock) - that's atomic. If the API sounds strategic or high-level (Intent, Business), it's not the one doing the low-level NETCONF work.
