Free Practice Questions for Nutanix NCA-6.10 Exam

The correct answer isD. Software-only Encryption.

Nutanix supportsData-at-Rest Encryption (DARE)through bothhardware-basedandsoftware-basedmethods. Among the supported solutions,software-only encryptionis a widely used and officially supported method, especially whenSelf-Encrypting Drives (SEDs)are not in use.

Key facts about Nutanix DARE:

Enables encryption of data written to physical media.

Works at theCVM and controller layer, ensuring all I/O is encrypted before being persisted.

Software-based encryptioncan be enabled via Prism Central or command-line usingNative Key Management (NKM)orexternal KMIP-compliant key managers.

Hardware encryption (SED)is optional and not required for DARE.

Clarifications:

A. Storage Pool-only Encryption: Not valid; encryption applies at thecluster level, not only to storage pools.

B. Data-only Encryption: Ambiguous and not a Nutanix-supported term.

C. Cluster-only Encryption: Misleading; encryption is applied to data at rest, not to the "cluster" object.

Prism UI Navigation Path:

Nutanix Security Guide – Data-at-Rest Encryption

Nutanix Bible – Encryption Section

Excerpt: “Nutanix supports software-only data-at-rest encryption using Native Key Management or external KMIP key managers, without requiring self-encrypting drives.”

Answer: D

APriority 1 (P1)case guarantees an8-hour response timefor customers with Production Support. P1 cases are designated for critical issues that severely impact business operations or cause a complete system outage, requiring immediate attention from Nutanix Support.

Other priorities:

P2: High-impact issues but not critical, response time varies.

P3: Medium impact, typically non-urgent issues.

P4: Low priority, general inquiries or minor issues.

When using the LCM (Life Cycle Manager) Dark Site procedure, theLCM Frameworkshould be checked and upgraded first. The LCM Framework is the core component responsible for orchestrating updates for other Nutanix software components. Ensuring the framework is up to date guarantees compatibility and reliability during subsequent upgrades.

A. MSP:Incorrect, as MSP (Managed Service Provider) is not directly related to the LCM Dark Site procedure.

B. Foundation:Incorrect, as Foundation is used for initial cluster deployment, not for lifecycle management.

C. NCC:While NCC is critical for health checks, it does not need to be updated first in the LCM process.

D. LCM Framework:Correct, as it manages the update process and must be updated first.

When multiple alert policies are applied to an entity, Nutanix uses a hierarchical approach. Policies applied toan entity type within a categorytake precedence. For example:

If a category (e.g., "Production") has policies applied to entities like VMs, and the entity matches that category, the category-specific policy will override general policies.

This prioritization allows administrators to fine-tune alert policies for specific workloads or environments.

When using ESXi as the hypervisor in a Nutanix cluster, the supported storage protocol for a datastore isNFS (Network File System). Nutanix exposes its distributed storage to ESXi hosts using NFS for VM storage. This protocol is simple to configure and provides high performance and reliability through Nutanix’s data services.

Other options:

iSCSI: Not typically used for ESXi datastores but can be utilized for specific use cases like external storage connectivity.

SMB: Not supported for ESXi datastores.

LVM: Logical Volume Management is not used in this context.

To enable Windows Defender Credential Guard, the VM must be configured withUEFI(Unified Extensible Firmware Interface) instead of Legacy BIOS. UEFI provides the necessary support for Secure Boot and Virtualization-Based Security (VBS), both of which are prerequisites for Credential Guard.

Steps:

When creating or editing the VM, selectUEFIas the firmware type.

Ensure Secure Boot and VBS are enabled in the OS configuration.

Nutanix Metro Availability provides the best Recovery Time Objective (RTO) because it enables synchronous replication between two sites. In the event of a failure at one site, VMs can be instantly restarted on the other site with minimal disruption. This setup ensures zero data loss and near-instantaneous recovery.

A. Async:Provides high RPO (Recovery Point Objective) but has a longer RTO compared to synchronous replication methods.

B. Availability Zone:This term refers to a general site setup, not specific to recovery objectives.

C. Metro Availability:Correct, as it uses synchronous replication for near-zero RTO.

D. NearSync:Provides better RPO than Async but does not match the RTO of Metro Availability.

The correct answer isB. UTC.

When creating Linux VMs in a Nutanix environment (or in any enterprise-grade production environment), it isbest practice to use UTC(Coordinated Universal Time) as the system timezone. This ensures:

Consistencyacross distributed systems

Accurate log correlation

Avoidance of issues with daylight saving time (DST)

Simplifiedcentralized monitoring and troubleshooting

Clarifications:

A (Eastern)andD (Central)are region-specific and may introduce time skew across systems.

C (Local)is ambiguous and depends on the underlying hardware or hypervisor setting, which can lead to inconsistent behavior.

Official Reference:

Linux Admin Best Practices

Nutanix Best Practices Guide – VM Provisioning Section

Excerpt: “For consistency across environments, it is recommended to configure all Linux virtual machines to use UTC timezone, particularly in clustered and distributed applications.”

The correct answer isA. br0.

InAHV (Acropolis Hypervisor),br0is thedefault native Linux bridgecreated on each hypervisor host. It is used for VM traffic and external communication. AHV leveragesOpen vSwitch (OVS)to manage virtual networking, but the bridge is exposed as br0 in the host's network configuration.

Key points:

br0connects VM virtual NICs (vNICs) to the physical network via the host's uplinks.

It is pre-configured during Foundation or cluster deployment.

virbr0is typical in KVM environments but isnot usedin AHV.

Official Reference:

Nutanix AHV Networking Guide

Nutanix KB #2027 – AHV Host Networking

Excerpt: “AHV uses br0 as the default bridge on the host, configured by Open vSwitch for guest VM networking.”

Answer: A

By default, Nutanix Lifecycle Manager (LCM) auto-inventory runs at2:00 AMlocal cluster time. LCM performs a daily check to gather information about available updates for firmware, software, and other components to ensure the cluster remains up-to-date. This operation is non-disruptive and does not impact cluster performance.
