  B. Filter VMs list, choose Test category and Inactive under Efficiency

• Question 225:

  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.
  A. Disable multicast and broadcast flood optimizations.
  C. Use a tagged VLAN for the CVM and hypervisor hosts.

  ---

  Explanation/Reference:

  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.

• Question 226:

  A customer wants to run SAP HANA on a Nutanix cluster with the following characteristics:

  1.

  AHV nodes

  2.

  SAP HANA version 2

  3.

  Production database files

  Which configuration should be recommended to the customer?

  A. Start with a cluster containing three or more nodes
  B. Enable only compression for the container that contains the Production database
  C. Do not enable compression, deduplication. or erasure coding on the storage container
  D. Plate the SAP HANA Database on the same socket as CVM
  C. Do not enable compression, deduplication. or erasure coding on the storage container

• Question 227:

  ---

  Explanation/Reference:

  In the scenario where the Foundation VM on a laptop is used for a cluster deployment, and an error indicating a failure to connect to the IPMIs is shown, the first troubleshooting step should be to disable the local machine's firewall to ensure it is not blocking traffic necessary for the Foundation VM to communicate with the IPMIs. Firewalls can often block essential ports or IP addresses needed for deployment operations, hindering the Foundation process.References: Nutanix Foundation Tool Troubleshooting Guide, Nutanix Deployment Common Issues.

• Question 229:

  An administrator needs to maximize storage potential in a six-node cluster. The container is configured with the following:

  1.

  Post-process compression

  2.

  Capacity deduplication

  What should the administrator configure to increase space savings?

  A. Erasure coding
  B. Inline compression
  C. Reserve capacity
  D. Cache dedupe
  A. Erasure coding

  ---

  Explanation/Reference:

  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.
