Scenario: A Citrix Administrator deployed a NetScaler in one-arm mode. Currently, the VLANs 20,30 and 40 are tagged on the interface with the option of ‘tagall’ on the interface.
What is true regarding the VLANs, when ‘tagall’ is enabled on the interface?
A. VLANS 1,20,30,40 and HA packets are tagged on the interface
B. VLANS 20,30 and 40 are tagged on the interface
C. VLANS 20,30,40 and HA packets are tagged on the interface
D. VLANS 1,20,30 and 40 are tagged on the interface

When you enable the tagall option on a NetScaler interface, all the VLAN traffic on that interface, including that of the Native VLAN (VLAN1), is tagged. This is necessary because some switch vendors tag all VLANs when the trunk option is enabled on these switches.
Correct Answer is D
The NetScaler appliance uses the native VLAN for the high availability traffic, which includes the heartbeats packets, synchronization, and command propagation. Therefore, you must ensure that the native VLAN has connectivity through all connected interfaces. By default, the native VLAN, VLAN1, is bound to an interface if you do not explicitly bind the interface to a VLAN.
