What next-generation feature is supported by the Cisco Meraki MS platform?

The Cisco Meraki MS switch platform supports Multigigabit Ethernet (mGig) on select models. This next-generation feature allows network uplinks and access ports to operate above standard 1 Gbps speeds—supporting 2.5, 5, or even 10 Gbps—over existing cabling infrastructure. It enables higher performance for Wi-Fi 6/6E access points and bandwidth-intensive devices. Therefore, the correct answer is A.
