During an initial discussion. a prospective customer indicates they are strongly considering vSAN for their HCI initiative. The prospect's workloads are mostly read-intensive and they have over 1PB of archival data.
The prospect expects to save on costs using storage efficiencies that their existing platform does not support.
Which two Nutanix differentiators should the systems engineer discuss? (Choose two.)
- A. Volume Group Load Balancing
- B. CVM Autopathing
- C. Data Locality
- D. Compression on Hybrid Nodes
正解：C、D
解説：
When discussing Nutanix differentiators with a prospect considering vSAN for their HCI initiative, especially for read-intensive workloads with over 1PB of archival data, the following features should be highlighted:
* Compression on Hybrid Nodes:
* Nutanix provides efficient data compression on hybrid nodes, significantly reducing the storage footprint and saving costs. This is particularly beneficial for archival data, which can be highly compressible, thus maximizing storage efficiency and reducing the total cost of ownership.
* Data Locality:
* Nutanix's data locality feature ensures that data is kept local to the node where the VM is running.
This reduces latency and enhances performance, particularly for read-intensive workloads, by minimizing the need for data to travel across the network.

* TSAnet(Technical Support Alliance Network) is an industry cooperative that provides multi-vendor support. Nutanix's participation in TSAnet ensures coordinated support efforts across vendors, including HPE (Nutanix Support Resources).
* Nutanix Software Only HCL:
* TheNutanix Software Only Hardware Compatibility List (HCL)provides a comprehensive list of supported hardware, ensuring that Nutanix software can be reliably deployed on HPE servers.
This official documentation helps counter FUD (Fear, Uncertainty, and Doubt) by verifying compatibility (Nutanix HCL).
* Conclusion:
* Leveraging TSAnet and the Nutanix Software Only HCL provides credible and verifiable evidence to overcome concerns about product supportability and partnership with HPE.

質問 # 89
An administrator is deploying several new application VMs to a Nutanix Cluster. The application is very transactional with a 28/72 random, read/write ratio. What should the administrator do?
- A. Add a minimum of four SSDs to each node to ensure all write go to the SSDs.
- B. Add one large SSD to each node and enable Flash Mode for the VMs.
- C. Add a minimum of four virtual disks to each VM and aggregate them on guest OS level.
- D. Add one large virtual disk to each VM and use it for all application data.
正解：C
解説：
* Understanding the Application Requirements:
* The application is very transactional with a 28/72 random, read/write ratio. This indicates a high write intensity, which necessitates optimized storage configurations to handle the I/O load efficiently.
* Add Multiple Virtual Disks:
* Option B: Add a minimum of four virtual disks to each VM and aggregate them on guest OS level:
* By adding multiple virtual disks and aggregating them within the guest OS, the I/O operations can be spread across multiple disks. This can significantly improve I/O performance by leveraging parallelism and reducing I/O contention on a single disk.
* This approach also helps in better utilizing the underlying storage infrastructure, which can
* include multiple SSDs and HDDs managed by Nutanix Distributed Storage Fabric (DSF).
* Analysis of Other Options:
* Option A: Add one large SSD to each node and enable Flash Mode for the VMs:
* Adding a single large SSD may not fully leverage the parallel I/O capabilities needed for high transactional workloads.
* Option C: Add a minimum of four SSDs to each node to ensure all writes go to the SSDs:
* While this improves performance, it focuses on node-level configuration rather than optimizing VM-level disk I/O distribution.
* Option D: Add one large virtual disk to each VM and use it for all application data:
* This creates a bottleneck as all I/O operations are directed to a single virtual disk, limiting performance improvements.
* Conclusion:
* For optimal performance of a highly transactional application with a high write ratio, adding multiple virtual disks and aggregating them within the guest OS is the most effective solution.

質問 # 90
Which three cluster operations require an administrator to reclaim licenses?(Choose three)
- A. Migrate a cluster
- B. Move Nodes between clusters.
- C. Destroy a cluster.
- D. Upgrade a cluster
- E. Remove a Node from a cluster
正解：B、C、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 # 91
A prospective customer's migration to their new SAN started six months ago and is sill not complete. The VP of IT state the previous migration to the existing SAN took almost eight months to complete. How should the systems engineer describe Nutanix hardware refreshes to this prospective customer
- A. Manual hardware refreshes take time, and the systems engineer understands the customer's current situation.
- B. Setting in AHV node's EVC mode is a very fast process that will shorten the upgrade time
- C. With AHV, vMotion between cluster occurs faster than on a SAN-based cluster
- D. New nodes can be added to an existing cluster. and then the old nodes can be removed.
正解：D
解説：
To describe Nutanix hardware refreshes to a prospective customer, the SE should emphasize the seamless process of adding new hardware to an existing cluster and decommissioning old hardware:
* Add New Nodes: New nodes can be added to the existing Nutanix cluster without downtime. This allows the cluster to temporarily expand its capacity and resources.
* Migrate Workloads: Once the new nodes are operational, workloads can be migrated from the old nodes to the new nodes using live migration features (e.g., AHV, vMotion).
* Decommission Old Nodes: After all workloads have been successfully migrated, the old nodes can be gracefully removed from the cluster.
* Minimal Downtime: This process ensures minimal to no downtime and allows for hardware refreshes without significant disruptions to operations.
This streamlined approach significantly reduces the complexity and time required for hardware refreshes compared to traditional SAN-based environments.

* Nutanix documentation on adding and removing nodes from a cluster.
* Best practices for performing hardware refreshes in Nutanix environments.
