You have a Windows Server 2016 failover cluster that contains two servers named Server1 and Server2
The Cluster Service on Server1 fails.
You need to identify the cause of the failure.
What should you do?
A. From Windows PowerShell, run the Get-ClusterNode cmdlet.
B. From Event Viewer, review the Application event log.
C. From Windows PowerShell, run the Get-ClusterLog cmdlet.
D. From Event Viewer, review the System event log.

not sure this article says always go to system event log first and then mentions Get-ClusterLog
