Question 141

Which action should an administrator take before performing planned maintenance on a Nutanix node?

1. Create a new DNS zone
2. Review the node’s maintenance requirements
3. Delete all VM categories
4. Disable storage efficiency

Correct Answer: 2

Explanation

Before performing planned maintenance on a Nutanix node, the administrator should review the required maintenance procedures and determine how workloads and cluster services will be affected. The node may need to be placed into an appropriate maintenance state so that the platform can handle the operation safely. Creating DNS zones, deleting categories, or disabling storage efficiency are not standard preparation steps for routine node maintenance. NCA candidates should understand that hardware maintenance requires planning, checking cluster status, and following supported procedures rather than making unrelated configuration changes.

Question 142

What is the primary purpose of placing a Nutanix node into maintenance mode?

1. Prepare the node for planned maintenance
2. Increase the VM’s memory
3. Create a storage container
4. Configure SMTP

Correct Answer: 1

Explanation

Maintenance mode prepares a Nutanix node for planned maintenance activities. It allows the platform to handle the node appropriately while administrators perform supported hardware or infrastructure work. The exact behavior depends on the cluster configuration and maintenance procedure, so administrators should follow Nutanix guidance before taking a node offline. Increasing VM memory, creating a storage container, and configuring SMTP are unrelated tasks. NCA candidates should recognize maintenance mode as an operational safeguard associated with hardware maintenance rather than as a VM, storage, or notification configuration feature.

Question 143

Which resource should an administrator consult to verify that planned software versions are supported together?

1. Network Visualizer
2. Compatibility Matrix
3. VM category
4. Snapshot list

Correct Answer: 2

Explanation

The Compatibility Matrix helps administrators verify whether software, firmware, hardware, and related components are supported together. This is especially important before performing upgrades because installing individually supported versions does not necessarily mean that every combination is supported. Network Visualizer provides networking information, categories organize entities, and snapshots represent point-in-time VM states. NCA candidates should recognize compatibility verification as an important part of software maintenance planning. Checking supported combinations before beginning an upgrade can help prevent avoidable compatibility problems and reduce the risk of an unsupported configuration.

Question 144

Which LCM function helps an administrator identify components and updates present in the environment?

1. Snapshot management
2. Network visualization
3. Inventory
4. VM cloning

Correct Answer: 3

Explanation

Life Cycle Manager inventory provides information about software and firmware components detected within the Nutanix environment and helps administrators understand what can be managed through the lifecycle process. Inventory is an important step before maintenance because administrators need to know which components are installed and which updates may apply. Snapshot management concerns VM recovery points, Network Visualizer focuses on networking, and VM cloning creates similar virtual machines. NCA candidates should recognize inventory as a fundamental part of lifecycle management and upgrade preparation.

Question 145

An administrator is preparing to upgrade a Nutanix cluster. Which step should be performed before starting the upgrade?

1. Verify prerequisites and compatibility
2. Delete all snapshots
3. Remove every VM category
4. Disable monitoring

Correct Answer: 1

Explanation

Upgrade preparation should include verifying prerequisites, compatibility, and the supported upgrade path before starting the actual software update. Administrators should confirm that the cluster meets the required conditions and that the intended versions are supported together. Deleting snapshots, removing categories, or disabling monitoring are not general prerequisites for every upgrade. NCA candidates should understand that software maintenance requires planning rather than simply selecting an update package. Checking prerequisites helps identify potential blockers before the maintenance operation begins and supports a more controlled upgrade process.

Question 146

What is an important characteristic of a dark-site Nutanix environment?

1. It cannot run virtual machines
2. It has limited or unavailable external connectivity
3. It cannot use storage containers
4. It must use only one VM

Correct Answer: 2

Explanation

A dark-site environment has restricted or unavailable external connectivity, which affects how software updates and other externally sourced resources are obtained. Such environments can still operate virtual machines, storage containers, and normal Nutanix workloads. However, administrators may need to use controlled offline procedures to obtain and transfer required update packages. NCA candidates should understand this distinction because software lifecycle operations differ between connected and dark environments. The key characteristic is the limited external connectivity, not a restriction on the number of VMs or storage features available.

Question 147

Which component helps provide out-of-band management access to supported Nutanix hardware?

1. Prism Central
2. AHV
3. IPMI
4. Nutanix Files

Correct Answer: 3

Explanation

IPMI provides out-of-band hardware management capabilities for supported systems. Because it operates independently of the normal operating system and virtualization management path, it can be particularly useful when a node has a software, operating system, or network problem that prevents normal administrative access. Prism Central provides centralized Nutanix management, AHV supplies virtualization, and Nutanix Files provides file services. NCA candidates should understand the difference between platform-level administration and hardware-level out-of-band management, especially when reviewing node maintenance and troubleshooting scenarios.

Question 148

Which expansion option is intended to provide additional compute resources without following the same storage role as a standard node?

1. Storage container
2. Compute-only node
3. Witness Service
4. Volume Group

Correct Answer: 2

Explanation

A compute-only node is intended to add compute resources while serving a different role from a traditional node that contributes both compute and storage resources. This can be useful when an environment needs additional CPU or memory capacity without proportionally expanding its storage footprint. A storage container is a logical storage location, Witness provides availability-related functionality, and a Volume Group manages related virtual disks. NCA candidates should understand the different node capabilities available during cluster expansion and select the option that matches the organization’s resource requirement.

Question 149

Which feature can provide an independent decision point for a supported two-node cluster configuration?

1. Witness
2. Compression
3. Collector
4. Foundation

Correct Answer: 1

Explanation

Witness provides an independent decision mechanism for supported two-node Nutanix configurations. During certain failure scenarios, it can help the cluster determine which side should remain active, reducing the possibility of conflicting cluster states. Compression is a storage efficiency feature, Collector gathers information, and Foundation assists with node deployment. NCA candidates should understand that Witness addresses availability and cluster decision-making rather than routine storage or deployment operations. Its role becomes particularly important in smaller environments where there may not be enough nodes to independently establish cluster state during certain failures.

Question 150

Which Nutanix feature can provide a visual representation of relationships among networking components?

1. Network Visualizer
2. LCM Inventory
3. Self-Service Restore
4. License Manager

Correct Answer: 1

Explanation

Network Visualizer provides a graphical view of networking relationships within the Nutanix environment. It can help administrators understand how virtual networking components are connected and can support troubleshooting when a connectivity problem is difficult to understand from individual configuration screens. LCM Inventory focuses on lifecycle components, Self-Service Restore addresses recovery, and license management handles entitlements. NCA candidates should recognize Network Visualizer as a networking visibility feature rather than a configuration-independent replacement for all networking administration. Its value comes from making network relationships easier to inspect.

Question 151

Which storage mechanism can maintain multiple complete copies of data for resilience?

1. Compression
2. Replication
3. Deduplication
4. Erasure coding

Correct Answer: 2

Explanation

Replication maintains multiple copies of data to provide resilience against certain failures. The configured replication factor determines the number of copies maintained for supported data. Compression reduces data size, deduplication eliminates unnecessary duplicate copies of identical data, and erasure coding uses data and parity information for protection. NCA candidates should understand that replication can increase storage consumption because additional copies require additional capacity. Recognizing the distinction between replication and other storage efficiency technologies is important when answering questions about Nutanix storage protection and capacity planning.

Question 152

What does a higher replication factor generally require?

1. Less physical storage capacity
2. No additional resources
3. Additional storage capacity for extra copies
4. Additional DNS servers

Correct Answer: 3

Explanation

A higher replication factor generally requires additional storage capacity because more copies of the data must be maintained. The benefit is increased resilience against certain failures, while the tradeoff is greater capacity consumption. Replication factor does not determine DNS requirements or eliminate the need for storage resources. NCA candidates should understand this relationship when evaluating storage configurations. Storage protection settings should always be considered together with available capacity because stronger redundancy can increase the amount of physical space required to maintain protected data.

Question 153

Which storage capability can improve efficiency by identifying identical data that has already been stored?

1. NTP
2. Deduplication
3. SMTP
4. Network Visualizer

Correct Answer: 2

Explanation

Deduplication identifies duplicate data and can reduce storage consumption by avoiding unnecessary copies of identical information when supported by the configuration and workload. This differs from compression, which reduces the size of data through encoding. NTP and SMTP are infrastructure services, while Network Visualizer is a networking management feature. NCA candidates should understand the specific purpose of storage efficiency technologies rather than treating them as interchangeable. Deduplication is particularly associated with redundant data elimination and can improve effective storage utilization.

Question 154

Which storage feature reduces the amount of space required to represent stored data without primarily eliminating duplicate copies?

1. Compression
2. Replication
3. Categories
4. SNMP

Correct Answer: 1

Explanation

Compression reduces the storage space required to represent data by using more efficient encoding methods. Its primary purpose is different from deduplication, which focuses on identifying and eliminating redundant copies of identical information. Replication provides additional data copies for resilience, categories provide logical classification, and SNMP supports infrastructure monitoring. NCA candidates should be able to distinguish these concepts because Nutanix storage administration includes multiple efficiency and protection mechanisms. When a question focuses specifically on reducing data representation size, compression is the relevant technology.

Question 155

Which Nutanix storage construct is useful when an application requires several related virtual disks to be managed together?

1. Volume Group
2. Category
3. Subnet
4. NTP

Correct Answer: 1

Explanation

A Volume Group allows multiple related virtual disks or volumes to be managed as a logical group. This can be useful for applications that require several storage devices and need them presented in an organized manner. Categories are used for logical classification, subnets provide networking, and NTP synchronizes system clocks. NCA candidates should understand the purpose of different Nutanix storage constructs and identify a Volume Group when a requirement involves multiple related block storage volumes. It is a storage-management feature rather than a networking or infrastructure-service component.

Question 156

Which information should an administrator examine when determining the current state of Nutanix licensing?

1. Network topology only
2. License assignment and expiration information
3. VM display resolution
4. Guest wallpaper

Correct Answer: 2

Explanation

License assignment and expiration information helps administrators determine the current licensing state of the Nutanix environment. Administrators may need to identify which licenses are assigned, which are available, and whether an entitlement is approaching expiration. Network topology and VM display settings do not provide licensing information. NCA candidates should understand that licensing administration includes checking the current state before making changes. Reviewing assignment and expiration details can help prevent unexpected licensing issues and ensures that the selected entitlement remains appropriate for the intended Nutanix deployment.

Question 157

Which action can make an assigned license available for another supported use?

1. Reclaim or unassign the license
2. Create a subnet
3. Clone a VM
4. Run a snapshot

Correct Answer: 1

Explanation

Reclaiming or unassigning a license can make an entitlement available for another supported use, depending on the licensing workflow and environment. Administrators should verify that the license is no longer required before changing its assignment. Creating a subnet, cloning a VM, and creating a snapshot do not affect licensing availability. NCA candidates should understand the basic lifecycle of Nutanix licenses, including assignment, inspection, unassignment, and reclamation. Proper license management helps ensure that available entitlements are used appropriately as infrastructure requirements change.

Question 158

Which cluster service resolves a hostname to an IP address?

1. SMTP
2. NTP
3. DNS
4. SNMP

Correct Answer: 3

Explanation

DNS, or Domain Name System, resolves hostnames and domain names into IP addresses and provides other name-resolution functions. Reliable DNS is important for many infrastructure services because systems often communicate using hostnames rather than directly using numerical IP addresses. SMTP handles email transmission, NTP provides time synchronization, and SNMP supports monitoring and management information. NCA candidates should recognize the role of DNS as part of cluster configuration and distinguish it from other common infrastructure services that may also be configured within the Nutanix environment.

Question 159

Which service is most appropriate when a Nutanix environment needs to send email notifications?

1. DNS
2. SMTP
3. NTP
4. SNMP

Correct Answer: 2

Explanation

SMTP is the protocol associated with sending email messages and is therefore used when a Nutanix environment needs email-based notifications through a configured mail service. Administrators may need to provide the appropriate SMTP server and related settings. DNS performs name resolution, NTP synchronizes system time, and SNMP provides management information for monitoring. NCA candidates should be able to identify these services by their primary functions. When the requirement is specifically related to email delivery, SMTP is the correct service to consider.

Question 160

Which service helps ensure that timestamps across Nutanix infrastructure remain synchronized?

1. NTP
2. DNS
3. SMTP
4. SNMP

Correct Answer: 1

Explanation

NTP helps synchronize system clocks with configured time sources so that infrastructure components maintain consistent timestamps. Accurate time is important for logs, authentication, certificates, monitoring, and troubleshooting because administrators often need to correlate events occurring across multiple systems. DNS handles name resolution, SMTP handles email delivery, and SNMP supports monitoring and management information. NCA candidates should recognize NTP as a fundamental cluster configuration service and understand that reliable time synchronization supports accurate operational records and coordinated infrastructure behavior.
