VMware Certified Professional 6.5 – Data Center Virtualization
Question No: 81
Which two statements are true for Predictive DRS? (Choose two.)
It balances resource utilization for virtual machines with unpredictable utilization patterns.
It integrates DRS with vRealize Operations Manager to balance workloads for virtual machines before resource utilization spikes occur.
It balances resource utilization based on a threshold#39;s algorithm that runs each night.
It determines the best placement and balance of virtual machines based on a threshold#39;s algorithm that runs each night in vCenter Server 6.5 Database.
Answer: B,C Explanation:
Predictive DRS using a combination of DRS and vRealize Operations Manager to predict future demand and determine when and where hot spots will occur. When future hot spots are found, Predictive DRS moves the workloads long before any contention can occur.
Each night it runs its Dynamic Threshold calculations which uses sophisticated analytics to create a band of what is 鈥渘ormal鈥?for each metric/object combination
Question No: 82
Which statements regarding datastore clusters meets VMware’s recommended best practices?
Clusters should contain only datastores presented from the same storage array.
Clusters should contain only datastores with equal hardware acceleration capability.
Clusters should contain only datastores with the same capacity.
Clusters should contain only datastores using the same connection method (iSCSI, FC, etc.).

A vSphere Administrator must ensure that a user is able to view and manage the system configuration in vSphere Web Client.
In the vCenter Single Sign-On domain, which group should the user be a part of?
Question No: 84
A vSphere administrator manages a cluster which includes critical and non-critical virtual machines. The cluster requires different permissions for contractors and non-contractors.
How can the administrator exclude the contractor group from some of the critical VMs?
Apply permission for both contractors and non-contractors on the cluster level.
Apply permission for both contractors and non-contractors on the cluster level. Remove permission on the critical VMs for contractors.
Remove permission for contractors on the cluster level. Apply permission on the critical VMs for non-contractors.
Apply permission for both contractors and non-contractors on the VMs. Remove permission on the critical VMs for contractors.
Answer: B Explanation:
To exclude the contractor group simple apply permission for both contractors and non- contrators on the cluster level. After that, remove premission on the critical VMs for contractors.
Question No: 85
What is a potential downside of having more than four paths per datastore?
limits the storage protocols
increases storage latency for VM
limits the path selection policies
limits the number of LUNs per host
Answer: D Explanation:
While using more than the required number of paths restricts the number of LUNs you can present to a host, it may also affect host resources such as CPU cycles and also every path from a host requires an initiator record and there may be a limit to the number of initiators per storage system.Large numbers of paths i.e in excess of 4 per host may be required in environments where bursts of I/O from other hosts sharing the storage system ports are unpredictable and severe, for example boot storm scenarios where 8 paths per host might be plausible.
Question No: 86
Which two featured require the use of Host Profiles? (Choose two.)
Question No: 87
An administrator wants to enable proactive HA by moving virtual machines automatically if a hardware alert is triggered.
What are the three required settings? (Choose three.)
Set vSphere DRS Automation to Partially Automated.
Turn on Proactive HA.
Set the Proactive HA Automation Level to Manual.
Set the Proactive HA Automation Level to Automated.
Turn on vSphere HA and vSphere DRS.
Answer: B,D,E Explanation:
Select Turn on Proactive HA.
Click Proactive HA Failures and Responses. Select from the following configuration options.
Option Description Automation Level
Determine whether host quarantine or maintenance mode and VM migrations are recommendations or automatic.
Determine what happens to partially degraded hosts.
Host.Config.Quarantine and Host.Config.Maintenance privileges are required to put hosts in Quarantine mode and Maintenance mode, respectively.
Question No: 88
An administrator has upgraded to vSphere 6.5 and also wants to use Kerberos authentication for NFS.
Which can be done to the existing NFSv3 volumes to enable this feature?
Perform a storage rescan on VMFS volumes.
Unmount the NFSv3 datastore, and then mount as NFSv4.1 datastore.
Nothing. All NFSv3 mounted datastores are upgraded automatically during vSphere upgrades.
Perform a scan of new storage devices.
Answer: B Explanation:
NFS 4.1 supports the Kerberos authentication protocol to secure communication with the NFS server
Question No: 89
Which is the correct sequence to upgrade a vSphere infrastructure?
vCenter Servergt;ESXi hostgt; VMware Toolsgt;VM compatibility
ESXi hostgt;vCenter Servergt; VMware Toolsgt;VM compatibility
vCenter hostgt; ESXi hostgt; VM compatibilitygt; VMware Tools
ESXi hostgt;vCenter Servergt; VM compatibilitygt;VMware Tools
Question No: 90
Which two statements describe why a vSphere DRS cluster would report load imbalance?
The configured migration threshold is too high.
The configured migration threshold is too low.
DRS is configured for Partially Automated.
Enhanced vMotion Compatibility (EVC) is enabled.
