Which of the following is not a feature and benefit of APIC-EM?

The understanding of Cisco APIC-EM (Application Policy Infrastructure Controller Enterprise Module) includes various features and benefits that aid in network management and automation. The correct choice indicates that "Private Key Encryption service" is not a feature of APIC-EM.

APIC-EM focuses on simplifying network operations and enhancing visibility and management through features such as the Network Information Database, which provides a centralized repository for network device information. It also supports Network Topology Visualization, allowing users to understand their network's layout and interconnections clearly, thus facilitating troubleshooting and monitoring.

Additionally, while Cisco Intelligent WAN Application pertains to the management of WAN connections and optimizing network resources, it operates more within the Cisco DNA (Digital Network Architecture) context and does not directly relate to APIC-EM itself, reinforcing the notion that private key encryption services are not a core feature attributed to APIC-EM.

Ultimately, recognizing that APIC-EM emphasizes automation, visibility, and management rather than specific encryption services provides a clearer understanding of its capabilities and design goals.
