質問 # 38
A prospect is seeking a Nutanix solution for a mission critical application that needs to sustain two simultaneous node outages and prefers that the cluster be able to fully rebuild both data and metadata in the event hardware issues.
what is the minimum number of nodes required for the cluster?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
A prospect is looking for a Nutanix solution for a mission-critical application that needs to sustain two simultaneous node outages and prefers the cluster to fully rebuild both data and metadata in the event of hardware issues. Here is the detailed explanation:
* Requirement Analysis:
* Sustain two simultaneous node outages.
* Fully rebuild both data and metadata after hardware issues.
* Feature Analysis:
* Nutanix clusters use Replication Factor (RF) to ensure data protection and availability. For RF3 (Replication Factor 3), which protects against two simultaneous node failures, a minimum of 5 nodes is required.
* To fully rebuild both data and metadata after failures, the system needs an additional node to ensure there is enough redundancy and performance.
* Conclusion:To achieve RF3 and sustain two simultaneous node failures while allowing full rebuild of data and metadata, a minimum of 6 nodes is required.

- A. AOS marks the replica as read only and waits until the original replica is back online to prevent corruption.
- B. AOS leverages Erasure Coding to maintain resiliency.
- C. AOS only overwrite the available copy and waits until the original copy is back online before restoring resiliency

正解：C、D
質問 # 41
An administrator finds that home shares cannot be configured in a new Files 3.5 deployment.
Why is this happening?
- A. Multi-protocol access is not configured.
- B. NFS default access is set to Read Only
- C. Access Based Enumeration is not enabled.
- D. The system is deployed as a single FSVM.
正解：D
解説：
In Nutanix Files (formerly known as Acropolis File Services or AFS) 3.5, home shares require a multi-FSVM deployment to function correctly. A single FSVM deployment does not support the configuration of home shares.
* Single FSVM Limitation: A single FSVM deployment lacks the necessary redundancy and performance capabilities required for supporting home shares. Home shares require multiple FSVMs to provide high availability and load balancing, which is essential for managing user home directories effectively.
* Home Shares Configuration: Home shares are designed to distribute user data across multiple nodes to ensure availability and performance. This distribution requires at least three FSVMs in a typical deployment setup.
* Troubleshooting: When home shares cannot be configured, one of the first checks is to ensure that the deployment consists of the required number of FSVMs. In this case, the deployment having only a single FSVM directly explains the issue.

正解：D
解説：
* Document Purpose:
* AReference Architectureprovides a comprehensive framework for designing, implementing, and managing a solution. It includes validated configurations, best practices, and deployment guidelines tailored to specific applications or workloads.

* This type of document is ideal for addressing concerns about the suitability and design of using Nutanix for Avaya IP Office migration as it includes detailed technical guidance and architecture designs that ensure compatibility and performance (Nutanix Bible, Architecture Overview section).
* Conclusion:
* Providing a Reference Architecture will address the prospect's concerns with a detailed, validated approach for deploying Avaya IP Office on Nutanix, ensuring a reliable and efficient migration.

質問 # 43
Which three cluster operations require an administrator to reclaim licenses?(Choose three)
- A. Destroy a cluster.
- B. Upgrade a cluster
- C. Migrate a cluster
- D. Move Nodes between clusters.
- E. Remove a Node from a cluster
正解：A、D、E
解説：
https://portal.nutanix.com/page/documents/details/?targetId=Web_Console_Guide-Prism_v4_7:lic_licensing_managing_c.html Reclaiming Licenses (Including License Renewal) You can reclaim and optionally re-apply licenses for nodes in your clusters:
You must reclaim licenses when you plan to destroy a cluster. First reclaim the licenses, then destroy the cluster. You do not need to reclaim Starter licenses. These licenses are automatically applied whenever you create a cluster, including after you have destroyed a cluster.
Return licenses to your inventory when you remove one or more nodes from a cluster. Also, if you move nodes from one cluster to another, first reclaim the licenses, move the nodes, then re-apply the licenses.
You can reclaim licenses for nodes in your clusters in cases where you want to make modifications or downgrade licenses. For example, applying an Ultimate license to all nodes in a cluster where some nodes are currently licensed as Pro and some nodes are licensed as Ultimate. You might also want to transition nodes from Ultimate to Pro licensing.
You must reclaim licenses when you renew licenses. First reclaim the expired licenses, then apply new licenses.

質問 # 46
A prospect customer's expected workload consists of the following: 110 vCPU 512GB RAM * 500TB Storage They need a solution to help decrease storage costs. The majority of their storage requirements come from an imaging application that stores scanned JPEG images. Which two Nutanix capabilities should be leveraged?
(Choose two.)
- A. Capacity Tier Deduplication
- B. Compression
- C. Erasure Coding
- D. Storage-Only Nodes
正解：B、C
解説：
To help decrease storage costs for a workload primarily involving an imaging application storing scanned JPEG images, the following Nutanix capabilities should be leveraged:
* Erasure Coding: This technology reduces the storage overhead by distributing data and parity across multiple nodes, thus requiring less physical storage while maintaining data resiliency.
* Compression: This reduces the storage footprint by compressing the data, which is particularly effective for data like JPEG images that can benefit significantly from compression.
質問 # 47
A customer needs to image nodes that are either bare metal or require a different hypervisor. Which Nutanix tool should be used?
- A. Foundation
- B. Move
- C. Era
- D. Prism Central
正解：A
解説：
Nutanix Foundation is the tool used for imaging nodes that are either bare metal or require a different hypervisor. Foundation is designed for bootstrapping the imaging and deployment of Nutanix clusters. It installs the desired version of the Acropolis Operating System (AOS) and the hypervisor of choice. By default, Nutanix nodes ship with AHV pre-installed, but Foundation can be used to re-image the nodes with a different hypervisor if required.

質問 # 49
A prospective customer has a requirement for Data-at-Rest-Encryption for all their data Which two license options are available to address this requirement? (Choose two)
- A. Starter with the Encryption SKU
- B. Pro with the Encryption SKU
- C. Pro
- D. Ultimate
正解：B、D
解説：
* Customer Requirement:
* Data-at-Rest-Encryption for all data.
* License Options:
* Pro with the Encryption SKU: This option allows customers to add encryption capabilities to the Pro tier.
* Ultimate: This tier includes built-in encryption features, providing comprehensive data security.
* Explanation:
* Pro with the Encryption SKU: Customers using the Pro tier can enhance their security by purchasing the additional Encryption SKU, which enables Data-at-Rest-Encryption.
* Ultimate: This tier natively includes encryption, offering an all-in-one solution for customers requiring high levels of data security without additional SKUs.
* Outcome:
* Customers can choose either of these two licensing options to meet their Data-at-Rest-Encryption requirements, ensuring that all their data is securely encrypted.
References: For detailed licensing information and encryption capabilities, refer to Nutanix documentation on security features and licensing tiers.
