質問 # 84
An 8-node hybrid cluster is configured with a Fault Tolerance level of 2 (RF3). All nodes are identical. Which simultaneous failures will result in VM data being unavailable?
- A. CVM being powered off on one node and two HDD failures on another node.
- B. Single SSD failure on one node and a single SSD failure on another node
- C. Two HDD failures on one node and a single SSD failure on another node
- D. SSD failures on two nodes and a CVM powered off on another.
正解：D
解説：
In an 8-node hybrid cluster configured with a Fault Tolerance level of 2 (RF3), the system can tolerate up to two simultaneous failures. However, if there are SSD failures on two different nodes and a CVM is powered off on another node simultaneously, the data availability is compromised. This combination results in losing the quorum necessary for maintaining data availability and integrity, leading to VM data becoming unavailable.

質問 # 98
An SE is using the output from RVTools to size the storage capacity for a Nutanix Cluster.
Which value most closely resembles the minimum required storage capacity that should be entered for the aggregate workload in sizer?
- A. 37 TB
- B. 39 TB
- C. 24 TB
- D. 15 TB.
正解：A
解説：
* Understanding RVTools Output:
* RVTools provides detailed information on the storage usage of virtual machines, including provisioned, used, and free space.
* Determining Storage Requirements:
* Aggregate Workload Sizing: The SE must consider the total storage requirements, including current usage and future growth, to ensure the Nutanix Cluster can handle the workload.
* Value Selection:
* 15 TB: Likely insufficient for a sizable environment.
* 24 TB: More significant but may still be insufficient for larger deployments.
* 37 TB: Appears to be a reasonable estimate for a substantial workload, considering both current usage and future growth.
* 39 TB: Very close but slightly overestimated compared to typical recommendations.
* Conclusion:
* The most accurate representation of the minimum required storage capacity for the aggregate workload in sizer is37 TB.

質問 # 100
A prospect has 8500GB of capacity provisioned for a non-production VMware cluster. As Part of migrating to Nutanix. the prospect agrees to convert any thick provisioned disks to thin provisioned disks. Based on additional data. the total active working set for the cluster has been datermined to be 1TB. When entering the Raw input workload into Sizer, what is the minimum amount of HDD Capacity required for the workload? ??
- A. 4.0TiB
- B. 3.0TiB
- C. 3.5TiB
- D. 7.5TIB
正解：B
解説：
To determine the minimum amount of HDD capacity required for the workload after converting thick provisioned disks to thin provisioned disks, we need to consider the active working set and the typical overhead for thin provisioning.
* Current Capacity:
* The prospect currently has 8500GB (8.5TiB) of provisioned capacity.
* Active Working Set:
* The total active working set for the cluster is determined to be 1TB.
* Thin Provisioning:
* Thin provisioning reduces the need for physical storage because it allocates storage on-demand rather than reserving the full capacity upfront.
* Nutanix typically advises planning for additional overhead to accommodate metadata, snapshots, and potential growth.
* Calculation:
* The rule of thumb for thin provisioning overhead is approximately 2-3 times the active working set to ensure adequate capacity for metadata and additional data growth.
Using the higher end of the multiplier (3 times):
1TB (active working set)×3=3TB1 \text{TB (active working set)} \times 3 = 3
\text{TB}1TB (active working set)×3=3TB
* Conclusion:
* Therefore, the minimum HDD capacity required for the workload when thin provisioning is applied would be around 3.0TiB.

* Nutanix Sizing Guidelines.
* Nutanix Documentation on Thin Provisioning and Storage Optimization.
