NEW QUESTION # 55
An administrator needs to configure cluster fault tolerance of 1N & 1D.
How many nodes must the cluster have for this task?
Answer: A
Explanation:
The 1N & 1D cluster fault-tolerance level is supported on a three-node cluster. It is designed to maintain access to data when one complete node and one additional disk fail concurrently, provided that the failures and remaining resources satisfy the documented resiliency conditions. To achieve this protection level, the platform configures replication factor 3 for the relevant data and maintains three metadata copies.
This configuration is distinct from standard 1N/1D fault tolerance, which protects against either one node failure or one disk failure and normally uses data replication factor 2. The ampersand in 1N & 1D is technically significant because it indicates simultaneous node-and-disk protection.
A two-node cluster uses a separate witness-based architecture and cannot provide this three-node 1N & 1D configuration. Nutanix documentation identifies three as both the required and supported node count for this specific fault-tolerance mode. Larger conventional clusters use their applicable fault-tolerance configurations rather than treating 1N & 1D as an arbitrary scalable setting.
Administrators must also verify that the cluster has sufficient resilient capacity before enabling the higher protection level. References: Prism 7.5 - One Node and One Disk Cluster Fault Tolerance and Cluster Fault Tolerance .
NEW QUESTION # 56
What is the default time that a Nutanix cluster will run an LCM auto inventory and auto update?
Answer: D
Explanation:
The default scheduled time for LCM automatic inventory and automatic update activity is 3:00 AM. This setting is used when Auto Inventory and Auto Update are enabled for a connected site. Administrators can modify the schedule when 3:00 AM does not align with the organization's operational or maintenance requirements.
Automatic inventory refreshes LCM's knowledge of installed software and firmware components and retrieves current update metadata from the configured Nutanix source. Nutanix also specifies that if an inventory operation has already completed within the preceding 12 hours, LCM can skip the scheduled auto- inventory because its component information remains sufficiently current. Automatic update in this setting applies to the supported automatically managed component-particularly Nutanix Cluster Check-rather than authorizing every available AOS, AHV, or firmware upgrade without administrator review.
The other answer choices do not represent the documented default. However, administrators should treat 3:00 AM as a configurable platform default rather than an assumed maintenance window. They must verify the configured schedule, time context, Internet connectivity, and update policy for the specific environment.

NEW QUESTION # 57
Which security option should be implemented to ensure that all intra-cluster communication is secured?
Answer: C
Explanation:
Network Encryption is the security control directed at protecting data while it traverses the network between Nutanix cluster components. It provides cryptographic confidentiality and integrity for supported intra-cluster traffic, preventing captured traffic from being interpreted or modified without detection. In AOS 7.5, the documented intra-cluster data-in-transit encryption capability specifically covers Stargate storage traffic.
Accordingly, the examination wording should be interpreted as asking which option cryptographically secures intra-cluster communications, for which Network Encryption is the only valid choice.
Network Segmentation serves a different purpose. It isolates traffic categories-such as management, backplane, or replication traffic-onto separate networks. Segmentation can reduce exposure and limit broadcast or failure domains, but isolated traffic is not necessarily encrypted. Cluster Lockdown restricts administrative access, particularly access paths involving hosts and Controller VMs; it does not encrypt packets moving between cluster services. "vSwitch Lockdown" is not the relevant Nutanix data-in-transit security mechanism.
The decisive distinction is therefore encryption versus isolation or access restriction. If the requirement is that intercepted traffic must remain unreadable, an encryption capability is required. Segmentation may complement that control, but cannot replace it.

NEW QUESTION # 58
Which number of node(s) can be placed into maintenance mode at the same time in a cluster?
Answer: A
Explanation:
Nutanix permits only one node per cluster to be placed in maintenance mode at a time. This restriction protects cluster availability and ensures that sufficient compute, storage and metadata services remain operational while maintenance is performed. Before entering maintenance mode, Prism verifies whether the cluster has adequate resiliency and whether the workloads hosted by the node can be evacuated or otherwise handled safely.
For AHV, the maintenance workflow migrates eligible user VMs to other available hosts. The Controller VM on the affected node is then placed into an appropriate maintenance state so that storage services can continue through the remaining CVMs. Attempting to maintain multiple nodes simultaneously could exceed the cluster' s fault-tolerance capability, particularly if another unplanned node or disk failure occurs during the procedure.
The limitation is cluster-wide, not one node per hardware block. The absence of powered-on VMs also does not authorize every node to enter maintenance mode because AOS storage and cluster-control services still depend on quorum and service availability.

NEW QUESTION # 59
An administrator needs to quickly deploy multiple VMs with identical configurations in Prism Central.
What is the most efficient approach?
Answer: D
Explanation:
A VM template provides a controlled master configuration from which administrators can deploy multiple standardized virtual machines. The template preserves the source VM's supported configuration, including its virtual hardware, operating-system disk, and other deployment properties. Prism Central also supports template versioning, allowing administrators to maintain and update the master image without manually rebuilding every new VM.
Snapshots preserve point-in-time VM data and are primarily intended for recovery, cloning, or data-protection workflows; they are not the principal mechanism for repeatedly provisioning standardized VMs. Categories attach metadata to entities for organization, policy assignment, governance, and automation, but they do not contain a deployable VM configuration. Volume groups provide block-storage resources that can be attached to one or more VMs and therefore do not satisfy the requirement for identical complete VM deployments.
Nutanix documentation describes a VM template as a golden image or master copy used to create VMs in Prism Central. Consequently, deploying from a template minimizes configuration variance and administrative effort. Reference: Prism Central 7.5 - VM Template Management .
