NCA-6.10 Exam Dumps - Nutanix Certified Associate (NCA) Questions and Answers

The correct answer isB. Internal NTP sources.

Nutanix strongly recommends configuringreliable internal NTP sources(e.g., enterprise-managed NTP servers or domain NTP servers) to ensure:

Time consistency across all nodes and CVMs

Accurate logging, monitoring, authentication (e.g., Kerberos), and cluster operations

Avoiding dependency onexternal/public NTPsources, which may berate-limited, unavailable, or blockedby firewalls

Clarifications:

A (Windows time sources):Generally discouraged unless they are configured to use a stratum 1/2 reliable upstream source.

C (Rate-limited sources):Not recommended; can result in dropped or inconsistent time updates.

D (External ISP NTP):Not preferred for production clusters due to reliability concerns.

Answer: B

The correct answer isB. Run Nutanix Cluster Check (NCC).

Before performingany upgrade procedure(AOS, Foundation, LCM, etc.), it is strongly recommended torun the Nutanix Cluster Check (NCC). This tool performs acomprehensive health assessmentof the cluster and validates its readiness for the upgrade, including:

Disk integrity

Network configuration

CVM health

Cluster services status

Prism UI Navigation Path:

Health > Run NCC Check (via Actions menu)

Command Line Alternative:

bash

CopyEdit

ncc health_checks run_all

Clarifications:

A (Put hosts into maintenance mode): Not required before upgrades; LCM handles host management automatically.

C (Put CVMs into maintenance mode): Not correct. CVMs must be operational during upgrades.

D (Clear all alerts): Irrelevant unless the alerts indicate upgrade-blocking issues, which NCC identifies.

Official Reference:

Excerpt: “It is strongly recommended to run NCC prior to starting the upgrade process to detect any cluster issues.”
