Which two paths are provided by deploying an OOB management network in a data center that uses Cisco Nexus switches? (Choose two.)
The correct answer is A. Layer 3 for vPC keepalive packets C. Layer 3 for monitoring purposes. An out-of-band (OOB) management network for Cisco Nexus switches provides a dedicated Layer 3 path for monitoring purposes and for transmitting vPC keepalive packets.

Why each option
An out-of-band (OOB) management network for Cisco Nexus switches provides a dedicated Layer 3 path for monitoring purposes and for transmitting vPC keepalive packets.
An OOB management network provides a reliable, independent Layer 3 path for vPC keepalive packets, ensuring that vPC peer devices can detect failures without relying on the data plane, thereby enhancing high availability.
The vPC peer link carries data plane traffic and is an in-band connection between vPC peer switches, not part of the OOB management network.
The OOB management network provides a dedicated Layer 3 path for monitoring purposes, allowing administrators to access, manage, and collect telemetry data from network devices without impacting or being affected by the operational data plane.
Layer 2 for server traffic is handled by the in-band data plane network, which forwards production traffic, not the OOB management network.
Layer 3 for server traffic is handled by the in-band data plane network, which forwards production traffic, not the OOB management network.
