NEW QUESTION # 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 virtual disks to each VM and aggregate them on guest OS level.
- B. Add one large SSD to each node and enable Flash Mode for the VMs.
- C. Add one large virtual disk to each VM and use it for all application data.
- D. Add a minimum of four SSDs to each node to ensure all write go to the SSDs.
Answer: A
Explanation:
* 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.

Refer to Exhibit.
When entering a Raw Input workload into Sizer, what amount of RAM should be used for the entire workload?
- A. 48GB
- B. 32GB
- C. 42GB
- D. 64GB
Answer: A
Explanation:
C: 48GB:
* Based on the provided exhibit, the SE should enter the total amount of RAM required for the entire workload into the Sizer tool. The exhibit shows multiple VMs with different memory allocations.
* Summing up the memory allocations: 8GB (VM1) + 8GB (VM2) + 8GB (VM3) + 8GB (VM4) + 8GB (VM5) + 8GB (VM6) = 48GB
* Therefore, the SE should input 48GB as the total RAM required for the workload.

NEW QUESTION # 93
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. 3.0TiB
- B. 4.0TiB
- C. 3.5TiB
- D. 7.5TIB
Answer: A
Explanation:
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.

NEW QUESTION # 100
A prospect provides sizing details for a new application that will require 15TiB of usable storage. The prospect needs to plan for an additional 20% storage growth as part of the initial purchase. Including capacity to fully re-protect in the event of a node failure, which configuration provides minimal cost while meeting the capacity requirement?
- A. Option A
- B. Option D
- C. Option B
- D. Option C
Answer: B
Explanation:
To determine the best configuration, we need to calculate the required storage, including the additional 20% growth and the capacity to re-protect in the event of a node failure:
* Initial Storage Requirement:
* Usable storage required: 15 TiB
* Additional storage for 20% growth: 15×0.2=3 TiB15 \times 0.2 = 3 \text{ TiB}15×0.2=3 TiB
* Total storage required: 15+3=18 TiB15 + 3 = 18 \text{ TiB}15+3=18 TiB
* Storage with Re-protection:
* To ensure data protection and availability, Nutanix typically uses a replication factor (RF) of 2, meaning each piece of data is stored twice.
* Therefore, the total raw storage needed: 18 TiB×2=36 TiB18 \text{ TiB} \times 2 = 36 \text{ TiB}18 TiB×2=36 TiB Given these calculations, we should look for a configuration that provides at least 36 TiB of raw storage.
Based on typical Nutanix node configurations, Option D provides the best balance of cost and capacity, ensuring that the requirement for 36 TiB of raw storage is met.
