質問 # 15
Shared storage for Windows Server Failover Clustering (WSFC) is a use case for which Nutanix Unified Storage solution?
- A. Files
- B. RF2
- C. Volumes
- D. FT1
正解：C
解説：
Shared storage for Windows Server Failover Clustering (WSFC) is a use case for NutanixVolumes. Nutanix Volumes provides block storage (via iSCSI) to external systems, such as WSFC nodes, allowing them to share storage for failover clustering. This configuration is essential for high availability in Windows environments.
Other options:
* Files: Provides file-based storage (NFS/SMB), not suited for WSFC shared block storage.
* FT1 and RF2: Refer to Fault Tolerance and Redundancy Factor, not storage solutions.

質問 # 16
When is deduplication recommended?
- A. Server workloads
- B. Linked Clone VMs
- C. Full clone VMs
- D. Cold data
正解：C
解説：
Deduplication is most effective withfull clone VMsbecause it reduces redundant data blocks stored on the cluster. Full clone VMs often contain identical OS and application files, making them ideal candidates for deduplication, which optimizes storage usage and improves efficiency.
Other options:
* Server workloads: May benefit from deduplication but not as significantly as full clone VMs.
* Linked Clone VMs: Already share base disk images, so deduplication offers limited benefits.
* Cold data: Deduplication is less effective for data that isn't accessed frequently.

質問 # 17
An administrator is considering a data protection strategy between two sites. There is a 10ms round trip latency between the two clusters. Which data protection solution can the administrator implement that minimizes data loss in the event of a disaster?
- A. Synchronous Replication
- B. Async DR
- C. NearSync Replication
- D. Metro Availability
正解：C
解説：
The correct answer isA. NearSync Replication.
Key Concepts from Official Nutanix Documentation:
Nutanix supports various types of data replication methods depending on the Recovery Point Objective (RPO), Recovery Time Objective (RTO), and the latency between the sites.
* Metro Availabilityrequires a maximum latency of<5ms RTTand is used forzero RPO synchronous replication. Since the given latency is 10ms,Metro Availability is not supportedin this case.
Reference: Nutanix Bible - Metro Availability Section
Prism UI Navigation: Protection Domains > Metro Availability
Synchronous Replicationis often synonymous withMetro Availabilityin Nutanix's implementation. Thus, it is similarly bound by the <5ms RTT requirement.
Async DR (Asynchronous Disaster Recovery)allows for more relaxed RPOs, typically1 hour or more, which doesnot minimize data lossin the event of a disaster.
NearSync Replicationsupports anRPO as low as 1 minuteand issuitable for up to 20ms RTT latency. It utilizeslightweight snapshotsandschedule-based replicationto deliverlow-RPO protectioneven over relatively long distances and moderate latencies.
Reference: Nutanix Data Protection Guide - NearSync Overview
Prism UI Navigation: Data Protection > Protection Domains > Schedule (with 1-minute RPO option) Detailed Source References:
Nutanix Data Protection and DR Guide - v5.x and later:"NearSync replication enables you to achieve RPOs as low as 1 minute and is designed to work with round-trip latencies of up to 20ms." Prism Central UI:Navigate toProtection > Data Protection > Protection Domains > Create Schedule# Set schedule type to "NearSync" and observe the 1-minute RPO options.
Hence, since 10ms RTTexceeds Metro Availability requirementsbut iswell within NearSync's acceptable latency, the best choice thatminimizes data lossis:

質問 # 19
Which Nutanix Disaster Recovery component or feature provides the best Recovery Time Objective (RTO)?
- A. Availability Zone
- B. Async
- C. Metro Availability
- D. NearSync
正解：C
解説：
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.

質問 # 20
Which statement best describes the Storage Pool?
- A. Group of Storage Containers
- B. Group of physical disks
- C. Group of vDisks
- D. Group of boot drives
正解：B
解説：
The correct answer isB. Group of physical disks.
In Nutanix architecture:
* AStorage Poolis theaggregation of physical storage devices(SSD, HDD) across all nodes in a cluster.
* Each storage pool backs one or moreStorage Containers, which are logical partitions used for data placement.
* Storage poolscannot span clustersand are always confined to the cluster in which they are defined.
Clarifications:
* A (Storage Containers): These are logical groupingswithinstorage pools.
* C (Boot Drives): These are not part of the pool.
* D (vDisks): These exist within VMs and are backed by containers, not pools directly.
Prism UI Navigation Path:
Storage > Storage Pools
Official Reference:
* Nutanix Bible - Storage Pool Definition
* Nutanix Storage Admin Guide
* Excerpt: "A storage pool is made up of physical disks from one or more nodes and serves as the physical storage foundation for containers."

What is the recommended step before performing any upgrade procedure?
- A. Clear all alerts in Prism
- B. Put the CVMs into maintenance mode
- C. Put the hosts into maintenance mode
- D. Run Nutanix Cluster Check
正解：D
解説：
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:
* Nutanix Upgrade Guide - Pre-upgrade Checklist Section
* Excerpt: "It is strongly recommended to run NCC prior to starting the upgrade process to detect any cluster issues."

- A. It can have a different hypervisor than the other nodes in the cluster.
- B. Nutanix Objects must be deployed.
- C. It must have the same hypervisor as the other nodes in the cluster.
- D. Nutanix Files must be deployed.
正解：C
解説：
The correct answer isC. It must have the same hypervisor as the other nodes in the cluster.
When adding astorage-only (SO) nodeto a Nutanix cluster:
* It mustrun the same hypervisoras the existing nodes.
* The SO node doesnot host VMsbut participates in thestorage layerto increase capacity and performance.
* Nutanix currentlydoes not support mixed hypervisors(e.g., combining AHV with ESXi) within the same cluster, even for storage-only nodes.
Clarifications:
* A & B:Neither Nutanix Files nor Objects are required for adding storage-only nodes.
* D:Cross-hypervisor configuration is unsupported at the cluster level.
Official Reference:
* Nutanix Hardware Administration Guide - Storage-Only Node Requirements
* Excerpt: "All nodes in a cluster, including storage-only nodes, must run the same hypervisor type."

- A. Select Escalate within the existing ticket.
- B. Open a new ticket with Nutanix Support.
- C. Select Reply within the existing ticket.
- D. Send an email to the technician.
正解：A
解説：
The correct answer isD. Select Escalate within the existing ticket.
When working with Nutanix Support, the mosteffective and structuredway to request a callback or faster response is touse the "Escalate" functionavailable in the Support Portal for the specific support case. This formally flags the case forpriority handling, prompting action such as:
* A direct call back from support.
* Assignment of a higher-tier engineer.
* Accelerated SLA response.
Clarifications:
* A. Emailing the technicianmay go unnoticed or be delayed.
* B. Opening a new ticketintroduces duplication and delays.
* C. Replying within the casedoes not prompt immediate re-evaluation unless escalation is used.
Official Reference:
* My Nutanix Support Portal Guide - Case Management
* Excerpt: "Use the 'Escalate' option within an open case to notify Nutanix Support that a higher level of engagement is required."
質問 # 27
An administrator is performing AHV upgrades on an 8-node cluster configured with Redundancy Factor 3.
How many nodes would be placed into maintenance mode simultaneously?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
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.

質問 # 28
An administrator wants to apply tags to licenses to simplify future renewals.
What interface would be used to complete this operation?
- A. Prism Central Licensing
- B. Clusters in the Support Portal
- C. License Inventory in the Support Portal
- D. Prism Element Licensing
正解：A
解説：
Applying tags to licenses to streamline future renewals is a task that can be completed inPrism Central Licensing. Prism Central provides centralized license management for clusters, enabling administrators to apply and manage license tags, which simplifies tracking and renewal tasks across multiple clusters. Here's how it works:
* Prism Central Licensing Overview:Prism Central includes a dedicated licensing interface that provides a consolidated view of all licenses associated with your clusters. From this interface, administrators can categorize licenses using tags such as "Renewal-2025" or "Production," making it easier to identify and manage renewals or assignments.
* Steps to Apply Tags in Prism Central:
* Navigate toPrism Central > Settings > Licensing.
* Select the desired license(s) from the list.
* Use the "Tags" option to create or apply predefined tags to categorize these licenses.
* Why Not Other Options?:
* A. Clusters in the Support Portal: The Support Portal is primarily used for support-related tasks, such as managing cases or accessing documentation, and does not include license tagging capabilities.
* B. License Inventory in the Support Portal: While the Support Portal allows you to view license inventory, it does not support operational tasks like tagging.
* D. Prism Element Licensing: Prism Element is focused on managing licensing for individual clusters and lacks the centralized management and tagging functionality available in Prism Central.

質問 # 30
An administrator wants to create a storage container for an application that has built-in redundancy. What should the administrator do?
- A. Enable RF1 and create an RF1 storage container.
- B. RF1 is enabled by default in a storage container.
- C. Create an RF1 storage container.
- D. Create an RF1 storage container and enable RF1.
正解：C
解説：
The correct answer isB. Create an RF1 storage container.
In Nutanix architecture,Replication Factor (RF)is set at thestorage container levelto optimize redundancy and performance for specific workloads. When an application hasits own internal redundancy, such as database clustering or distributed file systems, the administrator may choose toreduce Nutanix's redundancy to RF1, which stores onlyone copy of datain the cluster. This reduces overhead and maximizes usable capacity, but isnot fault-tolerantat the Nutanix level.
Key clarifications:
* RF1 is not enabled by default.Nutanix clusters default toRF2 or RF3depending on the configuration and number of nodes.
* RF1 must beexplicitly setwhen creating a storage container.
* There isno separate "enable RF1"setting outside of selecting RF1 at container creation; once selected, it applies directly.
Prism UI Navigation Path:
Storage > Storage Containers > Create Storage Container > Data Redundancy Level # Select "RF1" Official Reference:
* Nutanix Bible - Storage Layer and RF Explanation
* Nutanix Storage Administration Guide - "Creating Containers with Specific Replication Factor"
* Excerpt: "RF1 is typically used for workloads with native redundancy. It must be selected explicitly during container creation." Conclusion:Onlyoption Baccurately reflects this process.
質問 # 31
