Refer to the exhibit. All switches are configured with the default port priority value. Which two commands ensure that traffic from PC1 is forwarded over Gi1/3 trunk port between DWS1 and DSW2? (Choos

The command `spanning-tree port-priority 16` lowers the priority of the Gi1/3 interface on DSW2 (from default 128), making it more preferred in STP path selection and ensuring the link from DSW1 to DSW2's Gi1/3 is chosen as a forwarding path towards DSW2.

The `interface gi1/3` command is necessary to enter interface configuration mode on DSW2, allowing the subsequent `spanning-tree port-priority` command to be applied to that specific port.

Setting DSW1's Gi1/3 port priority to 0 would make it highly preferred, potentially causing DSW2's Gi1/3 to be blocked if DSW1 is closer to the root bridge or for specific VLANs.

This command only enters interface configuration mode on DSW1 and does not apply any changes to influence the STP path.

Setting the port priority to 128 is the default value and would not change the current STP behavior to favor the Gi1/3 link.
