In the scenario, which IP address is bound to VLAN 10?

• A. 192.168.10.11
• B. 192.168.10.10
• C. 192.168.20.10
• D. 192.168.30.10

Answer: (B)

In a VLAN-based network, each VLAN has its own IP subnet, and the interface that represents that VLAN (the SVIs or the gateway for that VLAN) is given an IP address within that subnet. That IP is the address bound to that VLAN—the address devices on that VLAN use to reach the network and for the gateway.

Here, the VLAN 10 subnet is 192.168.10.0/24, so the bound address must be an IP in that range assigned to the VLAN 10 interface. The scenario configures the VLAN 10 interface with 192.168.10.10, making it the bound IP for VLAN 10. Addresses in other subnets (192.168.20.10 and 192.168.30.10) belong to different VLANs and thus cannot be bound to VLAN 10. The remaining 192.168.10.x address is also in the correct subnet, but the specific binding in this setup is the 192.168.10.10 address.
