QuestionQ11

Configuring Identity Management and Authorization

A company has an Isilon cluster joined to an Active Directory (AD) domain. The company previously replaced its primary NTP server and added new NTP settings to the Isilon cluster. Users are now experiencing authentication failures.

What could be a reason for this behavior?

  • A Cluster and the AD are configured to use the same NTP server.
  • B AD is not configured to synchronize its time from the cluster.
  • C SMB time is not configured on the cluster to synchronize with the AD.
  • D Time between the NTP and the AD differentiates by more than 5 minutes.
Explanation

Dell OneFS requires the Isilon cluster and Active Directory to remain closely time-synchronized. If their clocks differ by more than five minutes, authentication fails; changing the cluster’s NTP configuration can introduce that excessive clock skew.
