Refer to the exhibits. An engineer is troubleshooting an issue in which the Gig0/2 interface on a Cisco switch named SW2 fails to become the root port. Which two commands must be run on SW2 to resolve

When applied to the Fa0/3 interface, the 'no spanning-tree cost 4' command removes a manually configured spanning-tree cost of 4 from that interface. This reverts Fa0/3 to its default higher cost (e.g., 19 for FastEthernet), making Gig0/2 (with a default cost of 4 or 2 for Gigabit Ethernet) the more preferred root port.

Entering configuration for Gig0/2 would be necessary if we wanted to change its cost, but the most effective solution here is to address the competing port's configuration.

Setting Gig0/2's cost to 4 would only be beneficial if its current cost was higher, but it might not resolve the issue if another port has an even lower or artificially configured low cost.

The 'interface Fa0/3' command is necessary to enter interface configuration mode for Fa0/3, allowing the engineer to apply the 'no spanning-tree cost 4' command specifically to that competing interface.

Setting Gig0/2's cost to 5 would make it less preferred than its default cost (typically 2 or 4 for GigE), thus preventing it from becoming the root port, which is contrary to the objective.
