Question 1

When using Prism Element to monitor cluster storage capacity, which metric indicates the usable space after accounting for replication factor and erasure coding overhead?

Accepted Answer

Effective Capacity

Answer

Effective Capacity reflects the actual usable storage after replication factor and erasure coding overheads are applied.

Question 2

An AHV cluster experiences a split-brain scenario. Which Nutanix component is responsible for maintaining quorum and preventing data inconsistency?

Accepted Answer

Zookeeper

Answer

Zookeeper maintains distributed coordination and cluster quorum on Nutanix, preventing split-brain data inconsistency.

Question 3

Which report type in Prism Central provides a historical trend of cluster-wide CPU and memory utilization for capacity planning?

Accepted Answer

Capacity Planning Report

Answer

The Capacity Planning Report in Prism Central provides historical utilization trends to forecast future infrastructure needs.

Question 4

After enabling Nutanix Volume Groups for external iSCSI access, an external initiator cannot discover targets. What should be checked first?

Accepted Answer

Data Services IP configuration on the cluster

Answer

The Data Services IP is the cluster-wide iSCSI target address; if not configured, external initiators cannot discover Nutanix Volume Group targets.

Question 5

A VM protected by Nutanix Leap (DR) fails to fail over to the recovery site. Which log file on Prism Central should be reviewed first?

Accepted Answer

/home/nutanix/data/logs/cerebro.INFO

Answer

Cerebro is the Nutanix data protection and replication service; its logs are the first place to investigate DR failover failures.
