How many uplink ports on the Supervisor Engine can be active at the same time?

In a Cisco switch architecture, particularly pertaining to models that utilize a Supervisor Engine, the design allows for a certain number of uplink ports to facilitate redundancy and load balancing. Specifically, many Supervisor Engines are designed with dual uplink ports, which enables both ports to be active simultaneously under certain configurations, promoting better bandwidth utilization and network reliability.

This dual-active capability is achieved through features such as EtherChannel or similar technologies, which aggregate the bandwidth of the active links while providing failover options. This configuration ensures that if one uplink were to fail, the other could seamlessly take over, maintaining network stability.

Options suggesting a single port or a greater number than two would not align with the typical configurations available on these devices given their redundancy and performance objectives. Hence, the choice indicating that two uplink ports can be active at the same time accurately reflects the operational features of the Supervisor Engine in question.
