• Question 51:

  Which three statements are correct regarding booting an ESXi Host from Fibre Giannel SAN? (Oioose three.)

  A. Direct connect topology is supported.

  B. Multipathing to a boot LUN on an active-passive array is supported.

  C. ESXi hosts do not require local storage.

  D. Each host must have its own boot LUN.

  E. Hosts can share one common boot LUN.

  Correct Answer: ACD

  Explanation: https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.storage.doc/GUID8FAD881D-7A00-43C9-AB69- 66DC7816968C.html

  When you use boot from SAN with multiple ESXi hosts, each host must have its own boot LUN.If you configure multiple hosts to share the same boot LUN, ESXi image corruption is likely to occur.Multipathing to a boot LUN on active-passive arrays is not supported because the BIOS does not support multipathing and is unable to activate a standby path. The correct answers are:- ABCDirect connect topology is supported. Each host must have its own boot LUN. ESXi hosts do not require local storage.

• Question 53:

  An administrator is trying to remove a host from a vSphere Distributed Switch named DSwitch01. The following error message is displayed:

  vDS DSwitch01 port 17 is still on host 192.168.100.23 connected to VM01 nic=4000 type=vmVnic

  Which two actions can the administrator make before removing the host from the vSphere Distributed Switch? (Choose two.)

  A. Migrate VM01 to DSwitch01 port 1.

  B. Add an additional vNIC to VM01 to another vSphere Distributed Switch.

  C. Migrate VM01 to another host.

  D. Disconnect the VM01's vNIC.

  E. Place VM01 into Maintenance Mode.

  Correct Answer: CD

  Before removing the host from distributed switch, migrate VM01 to Dswitch01 Port1. Then disconnect VM01 NIC.

• Question 54:

  A. Linux (32-Bit)

  B. Linux (64-Bit)

  C. Windows (64-Bit)

  D. Windows (32-Bit)

  Correct Answer: B

  The guest operating system that supports PVRDMA is Linux 64 bit.Guest OS Linux (64-bit)

• Question 55:

  A vSphere administrator observes a CPU spike on one of the web servers (view the Exhibit).

  

  Which two statements can describe the cause of this activity? (Choose two.)

  A. The network packet size is too large.

  B. Disk latency is present on the datastore.

  C. VMware Tools is not installed.

  D. The network packet size is too small.

  Correct Answer: BD

  Explanation: Network packet size is too small, which increases the demand for the CPU resources needed for processing each packet.https://docs.vmware.com/en/VMware- vSphere/6.5/ com.vmware.vsphere.monitoring.doc/GUID-C4EA86FD-95CB-4DE7-A9E3- 63F6BFC1A268.html Found this re disk latency:https://communities.vmware.com/thread/557063 The below also discusses Disk Performance issues and mentioned CPU usage:https://docs.vmware.com/en/VMwarevSphere/6.5/com.vmware.vsphere.monitoring.doc/GUID-E813116C-9D72-4464-BF3E1B19F70F45BE.html

• Question 56:

  Which statement is true regarding Network-Aware DRS?

  A. Network-Aware DRS will perform load-balancing based on the communication of virtual machines with one another.

  B. Network-Aware DRS is enabled through DRS advanced options.

  C. Network-Aware DRS only generated suggested moves; administrators must go in and accept each Network-Aware DRS suggestion manually.

  D. Network-Aware DRS will perform a final check during regular DRS load-balancing to ensure that the destination host is not network saturated.

  Correct Answer: D

• Question 57:

  DRS is set to Fully-Automated mode and seems to be migrating virtual machines too frequently.

  Which action can potentially decrease the amount of automated migrations performed by DRS?

  A. Increase the Migration Threshold by moving the slider to the right.

  B. Decrease the Migration Threshold by moving the slider to the left.

  C. Set DRS to Partially-Automated mode.

  D. Enable EVC for the cluster.

  Correct Answer: B

• Question 58:

  An administrator is trying to add a new virtual disk of 3TB to a virtual machine on a recently upgraded ESXi

  6.x host, but receives this error:

  The disk capacity entered was not a properly formed number or was out of range. It has been replaced with the nearest acceptable value.

  How can the new virtual disk be added to the virtual machine?

  A. Upgrade the VMFS datastore.

  B. Change the VMFS datastore block size to 8MB.

  C. Move the virtual machine to a datastore with free space.

  D. Use vmkfstools to upgrade to VMFS6.

  Correct Answer: B

• Question 59:

  What two migration paths are supported for Windows vCenter Servers? (Choose two.)

  A. vCenter Server 5.5 with an embedded vCenter Single Sign-On instance on Windows > vCenter Server Appliance 6.5 with an embedded Platform Services Controller appliance.

  B. vCenter Server 6.0 instance on Windows >vCenter Server Appliance 6.5 with an embedded Platform Services Controller appliance

  C. vCenter Server 6.0 instance on Windows >vCenter Server Appliance 6.5 with an external Platform Services Controller appliance

  D. vCenter Server 5.5 instance on Windows >vCenter Server Appliance 6.5 with an embedded Platform Services Controller appliance

  Correct Answer: AB

• Question 60:

  A vSphere administrator wants to reserve 0.5Gbps for virtual machines on each uplink on a distributed switch that has 10 uplinks.

  What is the quota that should be reserved for the network resource pool?

  A. 5Gbps

  B. 10Gbps

  C. 100Gbps

  D. 0.5Gbps

  Correct Answer: A

  For example, if the virtual machine system traffic has 0.5 Gbps reserved on each 10 GbE uplink on a distributed switch that has 10 uplinks, then the total aggregated bandwidth available for VM reservation on this switch is 5 Gbps. Each network resource pool can reserve a quota of this 5 Gbps capacity.
