Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
In the Tag field of the Layer 2 interface configuration
Why this is correct
The Tag field specifies the 802.1Q VLAN ID for the Layer 2 interface.
- ✗
Within the DHCP Server IP pool configuration
Why it's wrong here
DHCP server settings assign IP parameters to clients, completely separate from physical/logical interface VLAN tagging.
- ✗
In the Virtual Router general settings
Why it's wrong here
Virtual routers handle Layer 3 routing, whereas Layer 2 interfaces operate below the routing layer.
- ✗
Inside the Zone Protection Profile assigned to the interface
Why it's wrong here
Zone Protection Profiles protect against floods and spoofing, not interface VLAN encapsulation.
