A customer is considering increasing the Redundancy Factor from 2 to 3 for a Nutanix cluster in their existing environment. Which option would provide the company with the optimal solution?
A. Four Compute Nodes with 25% available disk space
B. Six Compute Nodes with 25% available disk space
C. Three Compute Nodes with 40% available disk space
D. Five Compute Nodes with 40% available disk space
Explanation:
To increase the Redundancy Factor (RF) from 2 to 3, at least five nodes are required for the cluster to function correctly with RF3, as each data block needs to be replicated to three different nodes. However, the optimal solution that offers both the necessary node count and sufficient storage overhead is:
Six Compute Nodes with 25% available disk space: This configuration ensures that there are enough nodes to support RF3 while maintaining adequate storage capacity for redundancy without overutilization.
An administrator is currently using both 10g uplink with LACP and balance-tcp. A single VM should not be allowed to use more than a single 10G uplink, and both uplinks should be utilized. Which two command should be used to configure the bond? (choose two)
A. Ovs-vsctl set port br0-up bond_mode=balance-slb
B. Ovs-vsctl set port br0-up bond_mode=balance-tcp
C. Ovs-vsctl set port br0-up bond_mode=active-backup
D. Ovs-vsctl set port br0-up other_config: bond-rebalance-interval=30000
A customer wants to use NIC teaming on an ESXi host using a vSphere Standard Switch configured with the Route based on physical NIC load load balancing option. The customer does not see the option when editing the Teaming and Failover settings for the switch. How should the consultant resolve this issue?
A. Change the load balancing option on the switch.
B. Add a vSphere Distributed Switch
C. Add another physical NIC to the team.
D. Install a vCenter server to manage the switch
Explanation: For a customer to use NIC teaming with the "Route based on physical NIC load" load balancing option on an ESXi host using a vSphere Standard Switch, they need vCenter Server. This specific load balancing method is not available on a vSphere Standard Switch without vCenter management, as it requires vSphere Distributed Switch capabilities that are managed via vCenter Server. By installing a vCenter server, the customer can upgrade from vSphere Standard to Distributed Switches and access more advanced features including the desired NIC teaming option.References: VMware vSphere Documentation, Nutanix Bible.
A consultant is setting up a new vSphere cluster. Customer requirements are as follows:
* VMs should automatically failover to another host if the host crashes
* Host CPU and Memory resources should be evenly balanced
* New VMs should be placed on the host with the most resources available
Which two settings should be turned on to meet the requirements? (Choose two.)
A. vShpere DRS
B. vSphere HA
C. vSphere vMotion
D. vSphere Power Management
A consultant asks a customer to verify the ToR Switch data port configuration was done according to Nutanix best practices. The switch configuration must simplify future deployments and expansions. Which two configuration actions will satisfy this requirement? (Choose two.)
A. Disable multicast and broadcast flood optimizations.
B. Configure the CVM and hypervisor host VLAN as the native.
C. Use a tagged VLAN for the CVM and hypervisor hosts.
D. Configure the connected switch ports as access.
Explanation: For a Nutanix cluster configuration that simplifies future deployments and expansions, disabling multicast and broadcast flood optimizations (A) and using a tagged VLAN for the CVM and hypervisor hosts (C) are the best practices. Disabling these optimizations helps in reducing unnecessary network traffic and potential broadcast storms in a growing environment. Using tagged VLANs for CVM and hypervisor hosts ensures proper network segmentation and scalability, allowing for easier management and expansion without reconfiguring the native network setup for each expansion or deployment.References: Nutanix Network Configuration Best Practices, Nutanix Deployment Guide.
An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between the servers must be limited to specific services/ports. There is an application layer firewall VM deployed on one host in the cluster. In which way should the administrator meet this requirement?
A. Create a network for each type of VM, and use policy-based routing to control the traffic flow
B. Configure a security policy and service chain redirecting the server traffic through the firewall
C. Separate the web. application and database VMs on to dedicated VLANs
D. Categorize the VMs in Prism Central and utilize Flow to set a security policy
An administrator wants to utilize Network Visualization to monitor the physical and logical network on the Nutanix cluster. The first-hop switch has LLDP enabled. The network switch information is still not being displayed.
What is causing this problem?
A. The ISL between switches is not configured.
B. SNMP is not configured properly.
C. br0 and br1 are not defined.
D. The cluster is using RDMA-enabled NICs.
An administrator needs to maximize storage potential in a six-node cluster. The container is configured with the following:
Post-process compression
Capacity deduplication
What should the administrator configure to increase space savings?
A. Erasure coding
B. Inline compression
C. Reserve capacity
D. Cache dedupe
Explanation: The administrator's goal is to maximize storage potential in a cluster already configured with post-process compression and capacity deduplication. Erasure Coding (EC-X) is an effective method to further increase space savings by reducing the amount of redundancy data required for fault tolerance. It splits data into multiple chunks, which are distributed across the cluster, and parity is calculated and stored. This method is more space-efficient compared to traditional RAID or mirroring techniques, especially in environments where large data volumes need efficient storage.
What reference materials should be provided to the customer during the Knowledge Transfer?
A. Questionnaire, technical slides and checklist, links to documentation and resources
B. As-Built Guide, technical slides and checklist, Network Diagram
C. As-Built Guide, Project Plan, links to documentation and resources
D. As-Built Guide, technical slides and checklist, links to documentation and resources
Explanation: During the Knowledge Transfer phase, providing the customer with the As-Built Guide, technical slides and checklists, along with links to documentation and resources, is optimal. This set of materials ensures the customer receives both detailed and high-level information, supporting a thorough understanding of the deployment and operational procedures, and it allows for easy reference to official resources for ongoing needs.

A consultant wants to expand a Nutanix cluster based on Dell PowerEdge servers and notices the nodes have arrived software-less.
Which two actions should the consultant take to expand the cluster? (Choose two.)
A. Image nodes using Foundation VM/App.
B. Use Expand cluster to expand duster.
C. Return nodes to factory for imaging.
D. Use Expand cluster to image the nodes.
During the knowledge transfer session, a consultant conducts a storage management demo. In the Creating a Storage Container workflow, the customer notices the Reserved Capacity parameter and asks for best practices related to it.
How should the consultant respond?
A. Nutanix recommends to configure at least 2 storage pools with at least one storage container each.
B. Do not reserve less than 90% of the total space in the storage pool.
C. Reserve capacity for a storage container only if the storage pool consists of single storage container.
D. Reserve capacity for a storage container only if the storage pool consists of multiple storage containers.
The networking team makes changes to the Top of Rack switches to which the Nutanix cluster are attached. A few VMs are able to communicate with each other on the same node but are unable to connect to other parts of the network.
What is the likely cause of this issue?
A. There is a VLAN misconfiguration on the VMs.
B. The vNIC port is disconnected on the affected VMs.
C. There is a VLAN misconfiguration on the switch.
D. Jumbo Frame are misconfigured across ports.
