NCA-6.10 Exam Dumps - Nutanix Certified Associate NCA v6.10

In a cluster configured with Redundancy Factor 3 (RF3), the system ensures that data is replicated across at least three nodes to tolerate the failure of two nodes. During an AHV upgrade, Nutanix only placesone node at a timeinto maintenance mode, even in an RF3 configuration, to minimize the impact on data redundancy and cluster operations.

A. 1:Correct, as AHV upgrades proceed node by node in RF3.

B. 2, C. 3, D. 4:These options are incorrect, as only one node is upgraded at a time regardless of RF3.

The correct answer isC. Pulse.

Pulseis Nutanix's integrated telemetry and support communication service. WhenPulse is enabled, it provides automatic delivery and updates of Nutanix software tools, including theNutanix Cluster Check (NCC)utility. This allows the system toautomatically download and apply newer versions of NCCwithout requiring manual intervention.

Clarifications:

A (LCM HTTPS):Refers to LCM transport protocol, unrelated to NCC updates.

B (Daily Digest):A reporting feature, not an update mechanism.

D (LCM Auto Inventory):Related to firmware/software inventory, not to NCC or system utilities.

Nutanix Support FAQ

Excerpt: “NCC auto-update is available when Pulse is enabled, allowing Nutanix to deliver updated NCC versions directly to the cluster.”

Answer: C

To prevent password access to the CVM for both thenutanixandadminuser accounts,Cluster Lockdownshould be enabled. Cluster Lockdown restricts SSH access to the Controller VM (CVM), effectively disabling password-based logins for enhanced security. Access is then managed through more secure means, such as console access or specific tools like Nutanix Support.

A. Cluster Lockdown:Correct, as this prevents SSH-based access to the CVM.

B. STIG:Incorrect, as STIG (Security Technical Implementation Guide) focuses on broader compliance measures.

C. RBAC Policy on PC:Incorrect, as RBAC (Role-Based Access Control) controls Prism Central permissions, not CVM access.

D. Data-at-Rest Encryption:Incorrect, as this secures stored data, not access credentials.

The default admin session logout time in Nutanix is15 minutes. If no activity is detected within this time, the session is automatically logged out for security reasons. This timeout can be adjusted in the system settings if needed, depending on organizational requirements.

For a cluster withRedundancy Factor 2 (RF2), at least4 nodesare required to configure Erasure Coding. Erasure Coding (EC) distributes data and parity across nodes to improve storage efficiency while maintaining data protection. RF2 requires a minimum of 4 nodes to ensure sufficient space for data and parity distribution.

Other options:

3 nodes: Insufficient for EC with RF2.

5 and 6 nodes: Can support EC, but the minimum requirement is 4.
