10 Tips For 2V0-621 examinee
Q31. A vSphere 6 High Availability cluster has been configured with default settings. Four virtual machines in the cluster have been configured with these priorities:
How many VM Overrides would need to be defined at the cluster level to meet the restart priorities?
Q32. Refer to the Exhibit.
An administrator receives vRealize Operations alerts for the Health of the virtual machine PVMAPP_0 as shown in Exhibit 1:
The administrator clicks on the Analysis pane, as shown in Exhibit 2:
Based on the exhibits, what action would correctly address the performance problems observed?
A. Increase the number of vCPUs for PVMAPP_0.
B. Increase the allocation of memory for PVMAPP_0.
C. Increase the Memory limit for PVMAPP_0.
D. Increase the reservation in MHz for vCPUs for PVMAPP_0.
Q33. An administrator is configuring Storage I/O Control. After enabling, the administrator notices high device latency and poor storage performance.
Which two actions would likely reduce latency and improve functionality? (Choose two.)
A. Set the congestion threshold to 15ms
B. Set the congestion threshold value to 5ms
C. Ensure that each datastore has independent spindles
D. Ensure that each datastore uses shared spindles
Q34. An administrator is troubleshooting a performance problem with a virtual machine (VM). The VM and ESXi host configuration is as follows:
. The application which runs within the virtual machine is highly sensitive to memory latency, but has low processor utilization.
. The virtual machine has 6 vCPUs.
. The ESXi host CPU topology has 2 Physical CPU Sockets, each with 8 Logical CPUs.
. The ESXi host CPU has Hyper Threading enabled.
The administrator would like to improve CPU performance for this VM. Other VMs on the host have no performance issues. Which action should the administrator take to resolve the issue?
A. Set the Advanced Parameter numa.vcpu.preferHT = TRUE in the virtual machine configuration file.
B. Set the Advanced Parameter numa.vcpu.preferHT = FALSE in the virtual machine configuration file.
C. Set the Advanced Parameter numa.PreferHT = 1 in the ESXi host configuration file.
D. Set the Advanced Parameter numa.PreferHT = 0 in the ESXi host configuration file.
Q35. An administrator tries to run esxtop to troubleshoot CPU performance issues, but no output is displayed.
How can the issue be resolved?
A. esxtop is deprecated in vSphere 6.x, resxtop must be used to produce the desired output.
B. In esxtop, press f and place an asterisk next to each field that should be displayed.
C. sudo should be run in front of esxtop to give the administrator the proper permissions.
D. The esxtop command must be run from the /proc directory to produce output.
Q36. Which two statements are true regarding Virtual SAN Fault Domains? (Choose two.)
A. They enable Virtual SAN to tolerate the failure of an entire physical rack.
B. Virtual SAN ensures that no two replicas are provisioned on the same domain.
C. Virtual SAN ensures that all replicas are provisioned on the same domain.
D. They require VMware High Availability (HA) to ensure component distribution across domains.
Q37. An administrator subscribes to the vCloud Air Disaster Recovery service.
Which replicated objects can be directly monitored and managed?
A. Virtual machine Snapshots
C. Virtual machines
D. ESXi Hosts
Q38. Deletion of an NFS datastore generates the following error:
Sysinfo error on operation returned the following status: Busy
Which step can be performed that will allow the deletion to complete successfully?
A. Storage vMotion any virtual machines on the datastore to another location.
B. Remove the datastore from the Storage DRS cluster in which it resides.
C. Verify the value of the NFS.HeartbeatDelta is not set to 0.
D. Suspend any running virtual machines and unmount the NFS datstore.
Q39. Where is a Virtual SAN Fault Domain configured?
A. VMware Virtual SAN Cluster configuration
B. VMware High Availability Cluster configuration
C. Distributed Resource Scheduler configuration
D. Datacenter Advanced Settings configuration
Q40. Refer to the Exhibit.
An administrator is attempting to enable Enhanced vMotion Compatibility (EVC), but receives the error shown in the Exhibit.
Which condition would explain the error?
A. The ESXi hosts are not licensed for EVC.
B. The administrator does not have privileges to enable EVC.
C. The ESXi host CPU has the Intel No-Execute feature disabled.
D. The administrator has turned on Intel Virtualization Technology.
