VMware VCP6-DCV 2V0-621D Questions & Answers

• Question 181:

  Refer to the Exhibit.

  

  A Storage Policy for a Virtual SAN is set to the default policy, as shown in the Exhibit. Which change would reduce the storage consumption by one third?

  A. Number of failures to tolerate = 1

  B. Number of disk stripes per object = 2

  C. Number of failures to tolerate = 3

  D. Number of disk stripes per object = 1

  Correct Answer: A

  Number of failures to tolerate defines the number of host, disk, or network failures a virtual machine object can tolerate. For n failures tolerated, n+1 copies of the virtual machine object are created and 2n+1 hosts with storage are required. Default value is 1. Maximum value is 3.

• Question 182:

  Which two statements are true regarding Storage Multipathing Plug-Ins? (Choose two.)

  A. The default Path Selection Policy is VMW_PSP_MRU for iSCSI or FC devices.

  B. The default Path Selection Policy is VMW_PSP_FIXED for iSCSI or FC devices.

  C. VMW_PSP_MRU is typically selected for ALUA arrays by default.

  D. VMW_PSP_FIXED is typically selected for ALUA arrays by default.

  Correct Answer: BC

• Question 183:

  Which three are requirements for configuring Storage I/O Control (SIOC)? (Choose three.)

  A. The datastore must consist of only one extent.

  B. The datastore is managed by a single vCenter Server.

  C. Auto-tiered storage must be compatable with SIOC.

  D. Auto-tiered storage must be SSD or SATA.

  E. The datastore must be VMFS.

  Correct Answer: ABC

  Storage I/O Control (SIOC) is used to control the I/O usage of a virtual machine and to gradually enforce the predefined I/O share levels. SIOC is supported on Fibre Channel and iSCSI connected storage in ESX/ESXi 4.1 and 5.0. With ESXi

  5.0 support for NFS with SIOC was also added. Datastores with multiple extents or Raw Device Mapping (RDM) are currently not supported. Reference: http://kb.vmware.com/selfservice/microsites/search.do? language=en_USandcmd=displayKC andexternalId=1022091

• Question 184:

  Refer to the Exhibit.

  

  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?

  A. Storage

  B. Deploy OVF Template

  C. New vApp

  D. Settings

  Correct Answer: A

  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 185:

  Which three statements are correct regarding Fibre Channel over Ethernet (FCOE)? (Choose three.)

  A. The network switch must have Priority-based Flow Control (PFC) set to AUTO.

  B. The network switch must have Priority-based Flow Control (PFC) set to ON.

  C. Each port on the FCoE card must reside on the same vSwitch.

  D. Each port on the FCoE card must reside on a separate vSwitch.

  E. The ESXi host will require a reboot after moving an FCoE card to a different vSwitch.

  Correct Answer: ADE

• Question 186:

  Which three traffic types can be configured for dedicated Vmkernel adapters? (Choose three.)

  A. Discovery traffic

  B. vMotion traffic

  C. vSphere Replication NFC traffic

  D. Provisioning traffic

  E. vSphere Custom traffic

  Correct Answer: BCD

• Question 187:

  A common root user account has been configured for a group of ESXi 6.x hosts.

  Which two steps should be taken to mitigate security risks associated with this configuration? (Choose two.)

  A. Remove the root user account from the ESXi host.

  B. Set a complex password for the root account and limit its use.

  C. Use ESXi Active Directory capabilities to assign users the administrator role.

  D. Use Lockdown mode to restrict root account access.

  Correct Answer: BC

  To address the security risks, yo need to set a complex password for the root account and make sure only authorized personnel use it. The second step is to use ESXi active directory to assign the administrator role to users.

• Question 188:

  An administrator notices that there is an all paths down (APD) event occurring for the software FcoE storage. What is a likely cause?

  A. Spanning Tree Protocol is enabled on the network ports.

  B. Spanning Tree Protocol is disabled on the network ports.

  C. Spanning Tree Protocol is enabled on the storage processors.

  D. Spanning Tree Protocol is disabled on the storage processors.

  Correct Answer: A

  Prevent all paths down event on FcoE storage by disabling STP on network ports.

• Question 189:

  Which command shows the Physical Uplink status for a vmnic?

  A. esxcli network ip get

  B. esxcli network nic list

  C. esxcli network vmnic list

  D. esxcli network ifconfig get

  Correct Answer: B
