A customer wants to convert S-Series stacked switches to a VLT configuration to maintain port-channels from the customer's server. The customer's S-Series stack currently uses IEEE 802.1D. The customer wants to upgrade to a faster converging protocol. The servers that connect to the stack use static port-channels, but the customer wants to use LACP going forward. The customer has approached a maintenance window for the weekend to make these changes. A network engineer has been given the following plan: - Obtain the appropriate S-Series code version from the customer - Upgrade the firmware of the S-Series switches - Convert to the VLT domain in the stack - Configure the port-channels down to the customer's servers - Utilize all existing cabling to proceed with the plan Which two pieces of information does the engineer need to proceed? (Choose two.)
