SQL SERVER Clustering

Hi,

We have clustered sql servers.

Servers:

1.abc.svr.india.net

Instance:

ARD01\SQLD01

2. xyz.svr.india.net

Instance:

ARD02\SQLD02

Nodes:

1.abc

2.xyz

When we execute query to check active node, it will give output as below

1.abc.svr.india.net

Select ServerProperty('ComputerNamePhysicalNetBIOS')

abc(output)

               
2. xyz.svr.india.net

xyz(output)

Please help me to understand  is it passive/active or active/active configuration.
Thanks in advance

Thanks
Shashikala
