Refer to the exhibit. Two new switches are being installed. The remote monitoring team uses the support network to monitor both switches. Which configuration is the next step to establish a Layer 2 co

The interfaces GigabitEthernet0/0 on both SwitchA and SwitchB are connected to end devices (PCs), serving as access ports. To establish Layer 2 communication between these PCs, the two switches must be physically connected to each other, typically using available interfaces like GigabitEthernet0/1, which would then be configured as a trunk link to carry traffic for the PCs' VLAN.

Choice B is incomplete and does not specify a meaningful configuration command beyond entering interface configuration mode, making it an invalid or insufficient step.

Configuring interface GigabitEthernet0/0 (SwitchA) is incorrect because it is already connected to PC1 and is likely an access port. This port is not used to establish the inter-switch link required for PC-to-PC communication across switches.

Choice D is incomplete and does not specify a meaningful configuration command beyond entering interface configuration mode for GigabitEthernet0/0, which is already connected to a PC.
