NEW QUESTION # 100
A two-node ROBO cluster is configured with a witness VM.
What happens when Node A goes down?
- A. Node B sends a leadership request to the Witness VM and goes into single-node mode.
- B. All operations and services on the Node B are shut down and go into a waiting state.
- C. The cluster is unaffected and no administrator intervention is required.
- D. The- cluster becomes unavailable and goes into read-only mode.
Answer: A

In a two-node ROBO cluster with a witness VM, if Node A goes down, Node B will send a leadership request to the Witness VM and then operate in single-node mode. This mechanism ensures that the cluster remains operational even when one of the nodes fails.
NEW QUESTION # 101
A customer needs to increase availability in their Nutanix environment by enabling rack awareness. The current configuration consists of : 1 RF2 cluster consisting of 7 identical NX-3170 1U nodes , All Storage efficiencies are disabled , Which two changes should the systems engineer propose to meet the customer requirements ? (Choose two)
- A. Distribute nodes across 3 separate racks.
- B. Add 1 additinal NX-3170 1U node.
- C. Add 2 additional NX-3170 1U nodes.
- D. Distribute nodes across 2 separate racks.
Answer: C,D
Explanation:
To increase availability by enabling rack awareness in a current configuration with a single RF2 cluster consisting of 7 identical NX-3170 1U nodes, the systems engineer should:
* Add Nodes: Increase the node count to enhance redundancy.
* Add 2 additional NX-3170 1U nodesto bring the total to 9 nodes. This ensures there are enough nodes to distribute across multiple racks while maintaining the RF2 configuration.
* Distribute Nodes Across Racks:
* Distribute nodes across 2 separate racksto achieve rack awareness. This means placing nodes in such a way that the failure of a single rack does not impact the availability of the entire cluster.
By following these steps, the cluster will be resilient to a single rack failure, enhancing the overall availability.
References:
* Nutanix documentation on RF2 configurations and rack awareness.
* Best practices for node and rack distribution to ensure high availability.

NEW QUESTION # 104
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. 7.5TIB
- C. 3.5TiB
- D. 4.0TiB
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 # 105

- A. Network Virtualization
- B. Prism Central
- C. Microsegmentation
- D. Network Segmentation
Answer: D
Explanation:
To logically separate management and data traffic on a Nutanix cluster, the administrator should use Network Segmentation.

NEW QUESTION # 109
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. New nodes can be added to an existing cluster. and then the old nodes can be removed.
- B. With AHV, vMotion between cluster occurs faster than on a SAN-based cluster
- C. Manual hardware refreshes take time, and the systems engineer understands the customer's current situation.
- D. Setting in AHV node's EVC mode is a very fast process that will shorten the upgrade time
Answer: A
Explanation:
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.
References:
* Nutanix documentation on adding and removing nodes from a cluster.
* Best practices for performing hardware refreshes in Nutanix environments.

Refer to the exhibit.
***Exhibit is Missing***
Based on the Sizing scenario, what level of resiliency can be inferred about the configuration?
- A. N+1
- B. N+2
- C. N+0
- D. RF3
Answer: A
Explanation:
B N+1:
* Based on the sizing scenario and the configuration shown in the exhibit, the Failover option selected is
"Standard (N+1)."
* This indicates that the cluster is configured to provide N+1 resiliency, where the system can handle the
* failure of one node by having an additional node available to take over.
