Which two circumstances might cause a DRS cluster to become invalid? (Choose two.)

A.    DRS has been disabled on one or more ESXi hosts.
B.    An ESXi host has been removed from the cluster.
C.    A migration on a virtual machine is attempted while the virtual machine is failing over.
D.    Virtual machines have been powered on from a vSphere Client connected directly to an ESXi host.

Answer: BD


Click the Exhibit button. An administrator has a DRS/HA cluster with five ESXi 5.x hosts. When the administrator tries to start a new Web server virtual machine, an error is displayed saying insufficient resources exist for HA.


Based on the HA configuration in the exhibit, which two changes can resolve the issue? (Choose two.)

A.    Shut down one or more virtual machines on the cluster.
B.    Set VM Restart Priority to Disabled for the Web server.
C.    Set Host Isolation response to Shut down.
D.    Suspend one or more virtual machines in the cluster.

Answer: AD
Shut down one or more virtual machines on the cluster and suspend one or more virtual machines in the cluster to prevent the insufficient resources error.

Click the Exhibit button. An administrator is applying patches to a batch of ESXi 5.x hosts in an under-allocated HA/DRS cluster. An attempt is made to place the host into maintenance mode, but the progress has stalled at 2%. DRS is configured as shown in the exhibit. Of the four choices below, two would effectively resolve this issue.


Which two steps could be taken to correct the problem? (Choose two.)

A.    Enable VMware EVC.
B.    Set the virtual machines on the host to Fully Automated.
C.    Shut down the virtual machines on the host.
D.    Move the virtual machine swap file off the local datastore.

Answer: BC
Set the virtual machines on the host to fully automated. This way they will be automatically placed onto hosts at power on and vCenter will suggest migration recommendations. Next, shut down the virtual machines on the host to resolve the progress that has stalled at 2%.

An administrator finds that vMotion and Storage vMotion operations do not succeed on a virtual machine. The virtual machine has been configured with N_Port ID Virtualization. The virtual machine has two data RDMs, one using a RAID5 LUN and one using a RAID0+1 LUN. The mapping file for the RAID5 LUN was created on the same datastore as the virtual machine, and the mapping file for the RAID0+1 LUN was placed in a datastore used for production data virtual disks. Which two statements are true about this configuration? (Choose two.)

A.    Storage vMotion cannot be used unless both mapping files are placed on the same datastore.
B.    vMotion cannot be used unless both mapping files are placed on the same datastore.
C.    vMotion cannot be used with RDMs.
D.    Storage vMotion cannot be used with NPIV.

Answer: BD

An administrator is configuring Storage DRS in their environment. The Datastore cluster is
composed of 4 VMFS3 volumes and 9 VMFS5 volumes. Storage DRS has been enabled, but is showing as disabled on several virtual machine disks in the datastore cluster.
Which two conditions would cause this error to occur? (Choose two.)

A.    The virtual machine is stored on a VMFS 3 volume.
B.    One or more virtual machines have Persistent disks.
C.    The virtual machine is stored on a NFS datastore.
D.    The virtual machine is stored on a datastore with a 2mb block size.

Answer: AB
Storage DRS does not work with VMFS 3 volume. So it will definitively show an error. If the error is shown on VMFS 5 volumes, it must be caused by the virtual machines that have persistent disks.

A company has converted several physical machines to virtual machines but are seeing significant performance issues on the converted machines. The host is configured with sufficient memory and storage does not appear to be a bottleneck.
Which metric can be checked to determine if CPU contention exists on an ESXi 5.x host?

A.    %RUN
B.    %WAIT
C.    %USED
D.    %RDY

Answer: D

Which three statements regarding Network I/O Control (NIOC) are accurate? (Choose three.)

A.    NIOC enforces traffic bandwidth limits on the overall vDS set of dvUplinks.
B.    NIOC limits maximum throughput control on connected virtual machines.
C.    Load based teaming efficiently uses a vDS set of dvUplinks for network capacity.
D.    Isolation provides priority to any one traffic flow.
E.    Relative shares fairly allocates available bandwidth among multiple flows.

Answer: ACE

Which three requirements must be met in order to use Storage I/O Control? (Choose three.)

A.    The datastore must contain multiple VMFS extents.
B.    The datastore must contain a single NFS volume.
C.    The datastore must not include virtual machines with snapshots.
D.    The datastore must be managed by a single vCenter Server.
E.    Array-based automated storage tiering must be explicitly certified.

Answer: BDE
Extents are only a single extent ?not multiples. Also, because NFS is not VMFS it does not use extents. You grow the NFS from the actual NAS appliance itself with extents.


What number of IOPS should be used with Storage I/O Control to limit disk throughput to roughly 10 MBps if the guest application writes 64KB blocks?

A.    320
B.    160
C.    240
D.    64

Answer: B

It appears that a single vCPU virtual machine in a resource pool called Production is having performance problems because it does not have enough CPU resources available.
Which two methods can be used to improve performance and reduce CPU contention of this virtual machine while maintaining compatibility with DRS? (Choose two.)

A.    Configure a CPU reservation for this virtual machine.
B.    Increase the CPU shares for the resource pool.
C.    Increase the CPU shares for the virtual machine.
D.    Increase the share priority setting for the Production resource pool.

Answer: AC
To improve performance and reduce CPU contention of this virtual machine, you need to configure a CPU reservation and increase CPU shares for this virtual machine.
