An administrator is deploying an application that requires maximum I/O throughput for scratch data. The administrator is concerned that the throughput requirement is greater than what can be provided by a single cluster node.
What should the administrator do to meet this requirement?
- A . Create a volume group with several virtual disks and attach to the VM
- B . Create a volume group with one virtual disk attached to the VM
- C . Create a virtual disk attached to the VM’s PCI interface
- D . Create several virtual disks attached to the VM’s virtual SCSI controller
An administrator learns that some security settings in a cluster have been changed. The environment is out of compliance with required policies.
Which function should be used to revert any settings that have changed from the defaults and prevent further violations?
- A . Cluster Lockdown with strong password enforcement
- B . Advanced Intrusion Detection Environment (AIDE)
- C . Security Configuration Management Automation (SCMA)
- D . Defense Information Systems Agency STIG enforcement
An administrator is managing multiple Windows and Linux VMs connected to Nutanix Volumes. The Linux VMs are experiencing intermittent connectivity issues. The Windows VMs do not experience the same issue.
Which option should the administrator use to resolve this issue?
- A . Utilize Jumbo Frames
- B . Add additional disks to the Volume Group
- C . Set the SCSI timeout value to 60
- D . Utilize a separate subnet for the Linux VMs
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
An administrator needs to evaluate if the existing configuration of Protection Domains meets the specified corporate recovery policy for SQL Data. The corporate policy requires that all SQL Servers be recoverable at the DR site within 30 minutes, and must result in a maximum of 60 minutes of data loss. SQL data must be required.
The protection domain is configured as follows:
• Application consistent snapshots are enabled
• The SQL server VMs are assigned to the Protection Domain as their own Consistency Group
• The Protection Domain schedule is configured as snapshots taken every 90 minutes from 7 am until 8 pm
What must be changed to meet the required policy?
- A . Revise the schedule tc be 15 minutes
- B . Revise the schedule to be 60 minutes
- C . Revise the schedule to be 30 minutes
- D . Revise the schedule to be 45 minutes
Refer to the exhibit.
An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.
What must be changed to enable full inter-VM communications?
- A . Change the network the VMs are connected to
- B . Change the spanning-tree port type on the switch
- C . The VMs need to have static IP addresses
- D . Update the switch to specifically allow VLAN 15
A VDI environment based on AHV Cluster is not performing well. The current environment is using only one bridge (Bridge0). The administrator needs to verify if nodes are using all network cards associated to Bridge0.
Which two menus should be used to check the current configuration? (Choose two.)
- A . Network Configuration item in Settings menu
- B . Host view in Network menu
- C . Host NICs tab in Hardware menu
- D . I/O Metrics tab in VM menu
A customer has NearSync configured. When the administrator tries to restore a snapshot from 3 minutes ago, it is not available. The snapshots are happening at 15-minute intervals instead of at the 5-minute configured interval. When the protection domain was initially set up, the snapshots were happening at the expected 5-minute interval.
What should the customer do to enable the snapshots to happen at the expected interval?
- A . Utilize Metro Availability to meet this requirement
- B . Change the protection domain to use Async DR
- C . Fix a connectivity issue because the protection domain reverted to Async
- D . Configure the protection domain to take snapshots on 15-minute intervals
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
An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)
- A . Stop all Nutanix Files clusters
- B . Relocate the linked LDAP servers
- C . Shut down all user VMs in the cluster
- D . Reconfigure IPMI for the new datacenter
