Which of the following is NOT a feature of the Cisco DNA Center?

Cisco DNA Center is designed as a comprehensive network management solution that emphasizes automation, security, and assurance throughout the entire networking ecosystem. Key features of Cisco DNA Center include automated network management, which streamlines the configuration and management of network devices, and network assurance and optimization that provides insights into network performance, helping to ensure reliable operations.

In-depth security analysis is also an integral part of Cisco DNA Center, as it provides advanced security features and insights that assist in maintaining a secure network environment. This capability highlights the system's role in addressing security concerns, which is crucial for modern network operations.

However, USB device connectivity is not a feature associated with Cisco DNA Center. The platform does not focus on direct USB connectivity for device management or services, as its core functionalities revolve around managing and orchestrating network devices through IP connectivity rather than USB interfaces. This makes it clear why USB device connectivity is the correct answer as the option that does not align with the primary offerings of Cisco DNA Center.
