An administrator is trying to vMotion a VM from his datacenter to a recovery site.
Which is the maximum allowed RTT (Round-Trip Time) latency between source and destination host?

A.100 milliseconds
B.150 milliseconds
C.15 milliseconds
D.10 milliseconds

정답:
Explanation:
Round-Trip Time for Long-Distance vMotion Migration If you have the proper license applied to your environment, you can perform reliable migrations between hosts that are separated by high network round-trip latency times. The maximum supported network round-trip time for vMotion migrations is 150 milliseconds. This round-trip time lets you migrate virtual machines to another geographical location at a longer distance.

Question No : 3

An administrator has recently upgraded from vSphere 6.0 to 6.5, and can no longer see the software iSCSI named vmhba33.
Which could be the reason for this?

A.The upgrade has changed the vmhba name.
B.vSphere 6.5 automates iSCSI configurations.
C.vSphere 6.5 no longer supports software iSCS
D.The upgrade has deleted the vmhba.

정답:
Explanation:
In vSphere 6.5, the name assigned to the iSCSI software adapter is different from the earlier releases. After you upgrade to the vSphere 6.5 release, the name of the existing software iSCSI adapter, vmhbaXX, changes.

Question No : 4

Which two situations could cause a virtual machine to appear with (orphaned) appended to its name? (Choose two.)

A.if a host failover is unsuccessful
B.if a virtual machine was removed from vCenter Server's inventory
C.if a virtual machine was deployed from template, and the template has been deleted
D.if a virtual machine is unregistered directly on the host

정답:
Explanation:
Virtual machines can become orphaned if a host failover is unsuccessful, or when the virtual machine is unregistered directly on the host. If this situation occurs, move the orphaned virtual machine to another host in the datacenter that has access to the datastore on which the virtual machine files are stored.

Question No : 5

Which two statements are true for Predictive DRS? (Choose two.)

A.It balances resource utilization for virtual machines with unpredictable utilization patterns.
B.It integrates DRS with vRealize Operations Manager to balance workloads for virtual machines before resource utilization spikes occur.
C.It balances resource utilization based on a threshold's algorithm that runs each night.
D.It determines the best placement and balance of virtual machines based on a threshold's algorithm that runs each night in vCenter Server 6.5 Database.

정답:
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 “normal” for each metric/object combination

Question No : 9

When installing vCenter Converter Standalone, why must an administrator perform a client-server installation instead of a local installation?

A.to manage conversion tasks remotely
B.to convert virtual machines as well as physical machines
C.to allow installation of the Converter agent on remote source machines
D.to hot clone physical or virtual machines

Question No : 10

Which is the block size on the VMFS6 datastore?

A.All small and large file blocks are 8M
B.All small and large file blocks are 1M
C.Small file blocks are 512K
D.large file blocks are 64M
E.Small file blocks are 1MB, large file blocks are 512M

정답:
Explanation:
File Block Format VMFS-6 introduces two new block sizes, referred to as small file block (SFB) and large file block (LFB). While the SFB size can range from 64KB to 1MB for future use-cases, VMFS-6 in vSphere 6.5 is utilizing an SFB size of 1MB only. The LFB size is set to 512MB.

An administrator attempts to manually reclaim space on thin-provisioned VMFS6 volumes but finds that no additional space is being recovered.
Which could be causing this?

A.vSphere 6.5 does not support manual UNMA
B.The manual UNMAP operation has been moved to the vSphere web client.
