A consultant successfully creates a Nutanix cluster. The consultant needs to configure containers for the customers business critical applications and general server workloads. The customer requirements are to achieve maximum storage space savings and optimize I/O performance. What setting(s) should the consultant enable on the storage container(s)?


A. Compression and deduplication


B. Deduplication only


C. Compression only





C.
  Compression only

For several days, an administrator notices the following alerts:

• CVM NIC Speed Low Warning Alerts
• Warning Alerts of CVM NIC not performing at optimal speed
• CVM is disconnected from the network Critical Alert
• Network Visualization page shows excessive dropped packets on CVM/Host

Which steps should be taken to determine which problem should be addressed first?


A. • Access the Hardware Page to verify resources are available
• Analyze ail CVM Speed Alerts in the Alerts/Events page
• Analyze output for the network and interface properties and connectivity issues


B. • Verify Host/CVM connectivity on the Network Visualization page
• Use to verify the bridge and bond configuration
• Review alerts/events page for the CVM disconnected error


C. • Review Alerts page for NIC speed alerts and alert timing
• Analyze the genesis.out log file for process failures
• Assess the NIC properties in the Network Visualization > Host Properties page


D. • Restart networking services on the CVM
• Determine the current configuration of the affected CVM via output
• Access the Alerts/Events page for the CVM network connection failures





B.
  • Verify Host/CVM connectivity on the Network Visualization page
• Use to verify the bridge and bond configuration
• Review alerts/events page for the CVM disconnected error

From a hypervisor, which IP address should the consultant use to connect to the locally tossed on?


A. 192.168.5.254


B. 172.16.19.2


C. 10.100.5.5


D. 192.168.1.254





A.
  192.168.5.254

Explanation: When configuring network settings for a hypervisor or accessing local services hosted on it, the IP address must be reachable from the network configuration you are currently using. Given the generic nature of the options, the correct choice typically depends on the subnet used for management purposes, which often uses a standard private address. "192.168.5.254" is a common choice for local network configurations and is likely set up as the gateway or a primary network interface on the hypervisor.

A consultant configures an ESXi cluster which will utilize a vSphere Distributed Switch (vDS). The consultant has just migrated the first host to the dvSwitch when several alerts appear within Prism Element regarding Host-to-CVM connectivity. What is causing these alerts?


A. The consultant migrated the CVM Backplane and VM network adapter over to the vDS.


B. The consultant migrated the CVM svm-iscsi-pg network adapter over to the vDS.


C. The consultant migrated the CVM Backplane network adapter over to the vDS.


D. VLAN tags are incorrectly configured on the vDS port groups.





A.
  The consultant migrated the CVM Backplane and VM network adapter over to the vDS.

Explanation: When migrating an ESXi host to a vSphere Distributed Switch (vDS), it's crucial to correctly configure network adapters, including those for the Controller Virtual Machine (CVM). If the consultant migrated both the CVM backplane and the VM network adapter to the vDS, this could disrupt host-to-CVM connectivity if not configured correctly on the vDS. Such a setup requires precise configuration of network settings and VLAN tags to maintain seamless connectivity and avoid communication alerts in Prism Element.

An administrator needs to forecast infrastructure requirements for a new program and its associated applications. Prior to the projected start of the new program, all existing applications will be decommissioned. How should the administrator perform this task?


A. Check the Disregard Existing Workloads radio button in the Runway scenario.


B. Check the Disregard Existing Nodes radio button in the Runway scenario.


C. Add up the recovered workloads and manually remove from the Runway configuration.


D. Power down the workloads during a maintenance window and run the Capacity Runway.





A.
  Check the Disregard Existing Workloads radio button in the Runway scenario.
