Not necessarily correct . You don't mention what kind of switch this is . More than likely this vlan is being routed by another device so its gateway on vlan 301 will be that device . If you look around you will find a connection to another routing device with vlan 301 on it . On layer 2 type switches the "interface vlan" or SVI is for managing the switch only and has nothing to do with any kind of routing for devices attached to that switch.
I agree with Glen but would take a slightly different emphasis. You assume that if the VLAN interface is shut down then the VLAN is down. But this confuses what happens at layer 2 with what happens at layer 3. If you shut down the VLAN interface then you stop the layer 3 processing of that VLAN on that switch. But it does not impact the processing of layer 2 on that switch. So the port remains active, the switch still maintains the mac-address-table and forwards to the PC connected to that port. And as long as there is an active layer 3 interface somewhere in that VLAN acting as default gateway for the PC then everything will work.
If the VLAN interface on this switch is shutdown then this switch is not providing layer 3 services (including routing) for VLAN 301. But as Glen pointed out, there is some other device that is providing the layer 3 routing. Perhaps there is another layer 3 switch in the network. Or perhaps there is a trunk port from the switch to some router that is doing inter VLAN routing.
It would be interesting to know what is configured on the PC as its default gateway.
