200-901 — Frequently Asked Questions

Edge computing reduces latency by processing data closer to the source, decreases bandwidth consumption by filtering data locally, and improves reliability for applications that require real-time responses.

It uses standardized data models (like YANG) to create a single source of truth, allowing for vendor-neutral, consistent, and automated configuration across different network devices.

The Configuration API is used to manage and configure objects within Cisco Unified Contact Center, including phone books and other system settings.

OAuth 2.0 is a token-based framework that allows applications to obtain limited access to an API on behalf of a user without handling the user's credentials directly.

Device-level management provides granular, direct control over individual devices, which can be advantageous for specific troubleshooting or in smaller environments where a centralized controller is not present.

Device-level management involves configuring each device individually (e.g., via CLI/SSH), while controller-level management uses a centralized platform to automate and push configurations to many devices at once.

This indicates a problem at the application layer. While basic connectivity (ping) and port accessibility (telnet) are working, the web server or API service itself might be down, misconfigured, or blocking the specific request.

It promotes loose coupling by allowing objects (observers) to subscribe to and be notified of changes in another object (the subject) without the subject needing to know the details of the observers.
