A customer needs to convert S-Series stacked switches to a VLT configuration to maintain port-channels from the customer's server. The customer's S-Series switches have been IEEE 802.1w compliant for spanning-tree and LACP for port-channels. The customer is NOT running multiple port-channels to servers, but the customer wants to be IEEE 802.3ad compliant. The customer has approved a maintenance window for the weekend to make these changes. A network engineer has been given the following plan: - Confirm the timings of the change window with the customer - Upgrade the firmware of the S-Series switches - Configure the switch-ports for VLT - Configure the port-channels down to the customer's servers - Configure LACP as the port-channel's negotiation Based on the provided plan, which two pieces of information does the engineer need to proceed? (Choose two.)
