Q: What is the typical use case for this module?
A: The C9300-NM-2Q is designed for high-bandwidth uplink connectivity in enterprise campus access layer deployments. Common applications include aggregating traffic from high-density access switches, supporting multiple Wi-Fi 6 access points, and providing scalable uplinks to distribution or core layer infrastructure.

Q: Does this module require a separate license?
A: No, the C9300-NM-2Q module itself does not require a separate license. However, the host Catalyst 9300 switch requires an appropriate Cisco DNA or Network software license tier (Essentials, Advantage, or Premier) for full feature access and ongoing support.
