VMware Certified Professional 6 – Data Center Virtualization Delta Beta Exam

Question No: 51 – (Topic 2)

  1. Disable hardware devices

  2. Disable unexposed features

  3. Disable Vmtools devices

  4. Disable VM Template features

Answer: A,B Explanation:

Question No: 52 – (Topic 2)

Which command shows the Physical Uplink status for a vmnic?

  1. esxcli network ip get

  2. esxcli network nic list

  3. esxcli network vmnic list

  4. esxcli network ifconfig get

Answer: B

Question No: 53 – (Topic 2)

Which two advanced features should be disabled for virtual machines that are only hosted on a vSphere system? (Choose two.)

  1. isolation.tools.unity.push.update.disable

  2. isolation.tools.ghi.launchmenu.change

  3. isolation.tools.bbs.disable

  4. isolation.tools.hgfsServerSet.enable

Answer: A,B Explanation:

Because VMware virtual machines run in many VMware products in addition to vSphere, some virtual machine parameters do not apply in a vSphere environment. Although these features do not appear in vSphere user interfaces, disabling them reduces the number of vectors through which a guest operating system could access a host. Use the following

.vmx setting to disable these features:

isolation.tools.unity.push.update.disable = quot;TRUEquot; isolation.tools.ghi.l”unch”enu.change = quot;TRUEquot; isolation.tools.ghi.a”tolo”on.disable = quot;TRUEquot; isolation.tools.hgfsS”rver”et.disable = quot;TRUEquot; isolation.tools.memSc”edFa”eSampleStats.disable = quot;TRUEquot; isolation.tools.getCr”ds.d”sable = quot;TRUEquot;

Question No: 54 – (Topic 2)

What are two limitations of Link Aggregation Control Protocol (LACP) on a vSphere Distributed Switch? (Choose two.)

  1. IP Hash load balancing is not a supported Teaming Policy.

  2. Software iSCSI multipathing is not compatible.

  3. Link Status Network failover detection must be disabled.

  4. It does not support configuration through Host Profiles.

Answer: B,D

Question No: 55 – (Topic 2)

An administrator creates a Private VLAN with a Primary VLAN ID of 2. The administrator then creates three Private VLANs as follows:

->Marketing

->PVLAN ID. 4

->PVLAN Type. Isolated

->Accounting

->PVLAN ID. 5

->PVLAN Type. Community

->Secretary

->PVLAN ID. 17

->PVLAN Type. Isolated

Users in the Accounting PVLAN are reporting problems communicating with servers in the Marketing PVLAN.

Which two actions could the administrator take to resolve this problem? (Choose two.)

  1. Change the PVLAN type for the Accounting network to Promiscuous.

  2. Change the PVLAN ID for the Accounting network to 2.

  3. Change the PVLAN type for Marketing network to Promiscuous.

  4. Change the PVLAN ID for Accounting network to 4.

Answer: A,B Explanation:

Change the PVLAN type for the accounting network to Promiscuous and the PVLAN ID to

  1. This way, the servers in Marketing PVLAN will communicate effectively.

    Topic 3, Configure and Administer Advanced vSphere Storage

    Question No: 56 – (Topic 3)

    An administrator observes that virtual machine storage activity on an ESXi 6.x host is negatively affecting virtual machine storage activity on another host that is accessing the same VMFS Datastore.

    Which action would mitigate the issue?

    1. Enable Storage IO Control.

    2. Configure Storage DRS.

    3. Enable the Dynamic Queue Depth Throttling option.

    4. Configure the Disk.SchedNumReqOutstanding parameter.

Answer: A Explanation:

SIOC is extremely powerful, it can increase your consolidation ratios on the storage side, allowing more VM#39;s per datastore. Which leads to lower storage costs and less administrative overhead.

So how does it work? At a basic level SIOC is monitoring the end to end latency of a datastore. When there is congestion (the latency is higher than the configured value) SIOC reduces the latency by throttling back VM#39;s who are using excessive I/O. Now you might say, I need that VM to have all of those I/O#39;s, which in many cases is true, you simply need to give the VMDK(s) of that VM a higher share value. SIOC will use the share values assigned to the VM#39;s VMDK#39;s to prioritize access to the datastore.

Just simply turning SIOC on will guarantee each VMDK has equal access to the datastore, shares fine tune that giving you the ability to give VMDK#39;s more or less priority during times of contention.

Question No: 57 – (Topic 3)

Refer to the Exhibit.

An administrator wishes to provide Load Balanced I/O for the device shown in the Exhibit. To meet this requirement, which setting should be changed?

  1. Storage Array Type Policy = VMW_NMP_RR

  2. Path Selection Policy = Round Robin (VMware)

  3. Storage Array Type Policy = VMW_SATP_RR

  4. Path Selection Policy = MRU (VMware)

Answer: B Explanation:

In round robin (VMware) the host uses an automatic path selection algorithm rotating through all available paths. This implements load balancing across all the available physical paths.

Load balancing is the process of spreading server I/O requests across all available host paths. The goal is to optimize performance in terms of throughput (I/O per second, megabytes per second, or response times).

A vSphere 6.x environment is configured with VMware Virtual Volumes (VVOLs). An administrator accesses the cluster Actions menu, as shown in the Exhibit.

Which option is used to create a VVOL on an existing VVOL container?

  1. Storage

  2. Deploy OVF Template

  3. New vApp

  4. Settings

Answer: A Explanation:

A storage container is the storage that is available physically on your storage array. Now I say physically but this could also be virtually presented storage even on an ESXi host but somewhere somehow it will be back-ended on some physical medium, be it HDD, SSD or hey, maybe even a super fast memory disk. Basically it’s a chunk of physical storage somewhere. Capacity Pools are logical partitions carved out of these to provide a chunk of storage to your VM Admins. Capacity pools may also span multiple storage arrays even across sites. Now you could have a single capacity pool within your storage container or multiple depending on your requirements if you need some sort of logical separation for say separate tenants or separate VM admins needing their own separate chunk of storage but just simply think of it as a chunk of storage presented to your VM admins.

Question No: 59 – (Topic 3)

An administrator is having a problem configuring Storage I/O Control on a Datastore. Which two conditions could explain the issue? (Choose two.)

  1. A host is running ESXi 4.0.

  2. An ESXi host does not have appropriate licensing.

  3. The vCenter Server version is 5.0.

  4. The vCenter Server License is Standard.

Question No: 60 – (Topic 3)

An administrator needs to recover disk space on a previously-used thin provisioned virtual disk. The volumes where the administrator needs to recover the disk blocks are on VAAI- compliant storage arrays.

Which two actions should the administrator take accomplish this task? (Choose two.)

  1. Perform a Storage vMotion to another volume in order to force free space recovery to occur. This recreates the volume in a new location and recovers all unused space.

  2. Use VMware Converter to migrate the virtual machine to a new datastore. This will recreate the volumes and recover all unused space.

  3. Issue the vmkfstools -vmfs unmap command within the VMFS volume directory on the ESXi host console.

  4. Execute the esxcli storage vmfs unmap command.

Answer: B,D
