Question # 1 An administrator is managing a highly active SQL workload that is writing I/Os in 2 MB chunks to a vDisk. The administrator wants to optimize capacity setting for the computer. Which storage optimization technology should the administration select to meet these requirement?
A. Erasure Coding B. Compression C. Capacity Deduplication D. Cache Deduplication
Click for Answer
B. Compression
Answer Description Explanation:
For highly active SQL workloads that write I/Os in 2 MB chunks to a vDisk, compression is the most suitable storage optimization technology. Compression works well with larger I/O sizes and can significantly reduce the storage footprint, providing better capacity optimization. This approach ensures that the large chunks of data are compressed efficiently, maximizing storage utilization and performance.
Question # 2 An administrator has an existing cluster and needs to improve performance Which two items are required to achieve even greater performance? A. Workloads are multi-threaded B. VMs have one vCPU configured C. VMs have multi-queue disableD. VMs have more than one vCPU
Click for Answer
A. Workloads are multi-threaded D. VMs have more than one vCPU
Answer Description Explanation:
Understanding the Requirements:
To improve the performance of an existing Nutanix cluster, it's important to consider the nature of the workloads and the configuration of the virtual machines (VMs).
Workloads are Multi-threaded (Option A):
Multi-threaded workloads can take advantage of multiple CPU cores, which helps in parallel processing and improves overall performance.
Nutanix clusters benefit from workloads that can efficiently utilize multiple threads since the underlying hypervisor (AHV or ESXi) can allocate multiple vCPUs to VMs, enhancing their performance capabilities.
VMs have more than one vCPU (Option D):
Assigning more than one vCPU to VMs allows them to process multiple instructions simultaneously, leveraging the multi-core capabilities of the physical CPUs.
This configuration is particularly beneficial for performance-sensitive applications that require more computing power and can significantly improve the performance of VMs on the Nutanix cluster.
Analysis of Other Options:
Option B: VMs have one vCPU configured:
This option limits the VMs to a single CPU core, which can bottleneck performance for multi-threaded applications and is not optimal for performance improvement.
Option C: VMs have multi-queue disable:
Disabling multi-queue can reduce the network performance by limiting the ability of the VMs to handle multiple network queues, which can be detrimental to performance.
Conclusion:
Therefore, to achieve greater performance, ensuring that workloads are multi-threaded and VMs are configured with more than one vCPU are the optimal strategies.
References: Nutanix documentation emphasizes the importance of configuring VMs with multiple vCPUs and supporting multi-threaded workloads to maximize performance in Nutanix clusters.

Answer Description Explanation:
To decrease costs and increase efficiency by eliminating NAS silos and adopting a cloud-like mindset, Nutanix Files is the appropriate product. Nutanix Files provides scalable, distributed file storage that integrates with the Nutanix ecosystem, offering efficient management and eliminating the need for separate NAS devices.
Question # 5 A systems engineer needs to size a new project that requires offsite backup using Veeam. The prospect requires an RPO of 24 hours, and the ability to restore from the past 7 days of backups. The prospect's data change rate is 1%. How should the SE configure the SE configure Sizer for this scenario? ???? A. Yes B. Mine C. Veeam D. Async E. HYCU
Click for Answer
C. Veeam
Answer Description Explanation:
To size a new project that requires offsite backup using Veeam with an RPO of 24 hours and the ability to restore from the past 7 days of backups, while considering the data change rate of 1%, the SE should configure the Nutanix Sizer with the following parameters:
Backup Frequency: Since the required RPO is 24 hours, a daily backup schedule should be set.
Retention Policy: The retention policy should be set to retain daily backups for 7 days. This means that each backup is kept for a week before it is overwritten.
Data Change Rate: The data change rate is 1%. This information is crucial for sizing the backup storage. A 1% daily change rate indicates that each daily backup will be approximately 1% of the total data size.
Backup Target: Veeam should be configured to send backups to an offsite location. This can be an external storage repository or a cloud target.
Storage Calculation: Calculate the total backup storage requirement. If the total data size is D, then the daily backup size will be 0.01D. Over 7 days, the storage requirement will be approximately 0.07D.
The SE should enter these details into the Nutanix Sizer to ensure the configuration aligns with the prospect's requirements.

Question # 6 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. 4 B. 5 C. 6 D. 7
Click for Answer
C. 6
Answer Description 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.
