Q21. An administrator notices that 8 out of 10 virtual machines have memory ballooning and swapping. However, virtual machine 9 is not ballooning or swapping and virtual machine 10 is not ballooning but is swapping.
Which two statements explain the behavior of virtual machine 9 and virtual machine 10? (Choose two.)
A. Virtual machine 9 has a 100% memory reservation.
B. Virtual machine 10 has a memory limit configured.
C. Virtual machine 9 has memory shares set to HIGH.
D. Virtual machine 10 does not have VMware Tools enabled or installed.
Q22. An administrator wants to ensure that all datastores defined on an ALUA-based storage array have load balancing enabled by default. The storage configuration is:
. Storage Array Type = VMW_SATP_DEFAULT_AA
. Path Selection Policy = VMW_PSP_FIXED
Which configuration would support the stated requirements?
A. Change the Storage Array Type Policy to = VMW_SATP_ALUA and the Path Selection Policy = VMW_PSP_RR.
B. Change the Path Selection Policy = VMW_PSP_RR and leave the Storage Array Type Policy as is.
C. Change the Storage Array Type Policy to = VMW_SATP_ALUA and leave the Path Selection Policy as is.
D. Change the Path Selection Policy = NMP and leave the Storage Array Type Policy as is.
Q23. 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.
Q24. Which two features are available for virtual machines configured with DirectPath I/O? (Choose two.)
A. Fault Tolerance
B. Suspend and Resume
C. Virtual Symmetric Multi-Processing (vSMP)
D. Virtual Non-Uniform Memory Access (vNUMA)
Q25. An administrator observes the following symptoms for a virtual machine:
CPU usage is consistently above 90%
CPU ready value is consistently above 20%.
Application performance is impacted.
Which two actions should the administrator take to improve the performance of this virtual machine? (Choose two.)
A. Increase the number of vCPUs assigned to this virtual machine.
B. Decrease the number of vCPUs assigned to this virtual machine.
C. Verify that VMware Tools is installed on every virtual machine on the host.
D. Increase the CPU shares assigned to the virtual machine.

A. Issue Events
B. Power off and restart virtual machines
C. Reset virtual machines
D. Leave Powered On
Q27. An administrator needs to configure a storage solution for a vSphere 6.x implementation with these characteristics:
Clustering across multiple ESXi hosts
Database application with high transaction count
vFlash Read Cache
Which solution meets all of the stated requirements?
A. A vmdk located on a Shared VMFS datastore
B. A Physical Mode Raw Device Mapped LUN
C. A Virtual Mode Raw Device Mapped LUN
D. A Virtual SAN-based vmdk
Q28. Strict Lockdown Mode has been enabled on an ESXi host.
Which action should an administrator perform to allow ESXi Shell or SSH access for users with administrator privileges?
A. Grant the users the administrator role and enable the service.
B. Add the users to Exception Users and enable the service.
C. No action can be taken, Strict Lockdown Mode prevents direct access.
D. Add the users to vsphere.local and enable the service.
Q29. Which three parameters should be considered when calculating the bandwidth for vSphere Replication? (Choose three.)
A. Data change rate
B. Traffic rates
C. Link speed
D. Application type
E. Hardware type
Q30. An administrator uses the df -h command and notices that an NFS datastore is reporting a
capacity of 0 Bytes.
What condition would cause this to occur?
A. The NFS server on which the datastore resides is down.
B. The datastore was mounted as Read/Write.
C. The datastore was mounted as Read-Only.
D. The datastore was created with NFS version 4.1.
