200-901 Cisco Platforms and Development Practice Question
An application uses Cisco DNA Center APIs and needs to receive notifications when a new device is added. Which DNA Center API category should be used to set up event-driven notifications?
⚠ Common exam trap
Many candidates confuse the functional categories of DNA Center APIs with the Platform category, which specifically handles event subscriptions and notifications, leading candidates to choose a network operations category instead.

Correct answer & explanation
✓
Platform
The Platform API category in Cisco DNA Center provides the necessary endpoints for subscribing to event notifications, including the ability to create webhook subscriptions for events such as new device additions. This category includes the Event Management and Notification APIs that allow applications to receive real-time updates. The other categories focus on network operations, not event-driven integration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Platform
Why this is correct
Platform APIs include the event notification and webhook services that register subscribers and deliver DNA Center events, such as device-added, to an external endpoint. This satisfies the stem's event-driven requirement, unlike intent, command runner or integration APIs, which handle policy, CLI execution or third-party connectivity rather than push notifications.
- ✗
Change your network
Why it's wrong here
The 'Change your network' category exposes APIs that modify device or fabric configuration, so it cannot deliver asynchronous event notifications when a device is added. It is tempting because adding a device changes the network, and would be correct for programmatically provisioning or updating network settings.
- ✗
Know your network
Why it's wrong here
Know your network covers device inventory and topology queries, not event subscription. It cannot register a webhook or deliver push notifications when a device joins. It is tempting because it does relate to device discovery, but it answers "what is on my network", whereas the Events API is required for event-driven notification delivery.
- ✗
Run your network
Why it's wrong here
The 'Run your network' category covers operational APIs such as monitoring, troubleshooting and command runner, which return data on request rather than pushing event-driven notifications. It is tempting because device onboarding is an operational event, and would be correct for querying device health or issuing show commands.
