NEW QUESTION 1
What is a potential downside of having more than four storage paths per datastore?

  • A. increases storage latency for VM
  • B. limits the number of LUNs per host
  • C. limits the storage protocols
  • D. limits the path selection policies

Answer: B

NEW QUESTION 2
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

Answer: B

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 (RTT) lets you migrate virtual machines to another geographical location at a longer distance.

NEW QUESTION 3
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.

Answer: D

NEW QUESTION 4
Which two components are necessary for the first boot of a host using Auto Deploy? (Choose two.)

  • A. Host Profiles
  • B. Bulk licensing
  • C. vSphere Authentication Proxy
  • D. TFTP
  • E. DHCP

Answer: DE

NEW QUESTION 5
How can failback of a recovered virtual machine in vSphere Replication be performed?

  • A. No action required, because failback is automatically performed to the source site.
  • B. Configure a new replication in the reverse machine at the target site.
  • C. Power off and unregister the virtual machine on the target site.
  • D. Disable or Stop the virtual machine replication on the source site.

Answer: B

Explanation: Failback of Virtual Machines in vSphere Replication
Failback of virtual machines is a manual task in a vSphere Replication.
After performing a successful recovery from the primary site to the secondary site, you can perform failback. You manually configure a new replication in the reverse direction, that is, from the secondary site to the primary site. The disks of the primary site are used as replication seeds, so that vSphere Replication only synchronizes the changes made to the .vmdk files. Before you configure the reverse replication, you must manually unregister the virtual machine from the inventory on the primary site.

NEW QUESTION 6
A scripted upgrade of ESXi fails due to an incorrect parameter in the upgrade script. What file must the administrator modify to correct the problem?

  • A. boot.cfg
  • B. vmreconfig.pl
  • C. ks.cfg
  • D. hostinfo.pl

Answer: A

NEW QUESTION 7
What two services run on all nodes in a vCenter Server HA cluster? (Choose two.)

  • A. vmware-vmon
  • B. vmware-vpostgres
  • C. vmare-rbd-watchdog
  • D. vmware-vcha

Answer: AD

NEW QUESTION 8
Which are three supported storage requirements for vCenter Server HA? (Choose three.)

  • A. NFS
  • B. RDM
  • C. vSAN
  • D. VMFS
  • E. JBOD

Answer: ACD

Explanation: vCenter HA is supported and tested with VMFS, NFS, and vSAN datastores.

NEW QUESTION 9
An administrator is troubleshooting network communications between a vCenter Server and an ESXi 6.5 host. Which log shows the related events between these components?

  • A. /var/log/fdm.log
  • B. /var/log/vpxa.log
  • C. /var/log/hostd.log
  • D. /var/log/auth.log

Answer: B

NEW QUESTION 10
Which setting will allow a virtual machine to have direct secure access to an RDM?

  • A. NIOC
  • B. NPV
  • C. NPIV
  • D. CPUID Mask

Answer: C

NEW QUESTION 11
When working with VM-VM DRS rules (affinity/anti-affinity), which statement is correct?

  • A. DRS gives higher priority to preventing violations of affinity rules than violations of anti-affinity rules.
  • B. DRS gives the same priority to preventing violations of anti-affinity rules as affinity rules.
  • C. DRS does not allow both affinity and anti-affinity rules to be enabled at the same time within a cluster.
  • D. DRS gives higher priority to preventing violations of anti-affinity rules than violations of affinity rules.

Answer: A

Explanation: When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled. DRS only tries to satisfy enabled rules and disabled rules are ignored. DRS gives higher precedence to preventing violations of anti-affinity rules than violations of affinity rules.

NEW QUESTION 12
Which is the purpose of VM Component Protection (VMCP)?

  • A. Reconnect virtual NICs that become disconnected
  • B. Respond when a datastore encounters a PDL or APD failure.
  • C. Restart applications when they are no longer running.
  • D. Respond when viruses are detected inside a virtual machine.

Answer: B

NEW QUESTION 13
What counter should an administrator check to determine if a virtual machine is ballooning?

  • A. swapinRate
  • B. vmmemctl
  • C. vmmemctltarget
  • D. swapped

Answer: B

Explanation: Memory Ballooning is the memory reclamation technique used by hypervisor to reclaim the memory back from the virtual machine.
When ESXi host running low on physical memory, It uses ballooning driver (vmmemctl.sys) to determine the how much memory from virtual machines can be get back to prevent the hypervisor swapping.

NEW QUESTION 14
Which method is supported for backing up the virtual machine that contains vCenter Server?

  • A. incremental
  • B. individual disks
  • C. differential
  • D. full image

Answer: D

NEW QUESTION 15
What are two features introduced in Network I/O Control version 3? (Choose two.J

  • A. Bandwidth reservation per traffic type
  • B. Bandwidth guarantee to virtual machines
  • C. Network resource pools
  • D. CoS tagging

Answer: AB

NEW QUESTION 16
Which three storage protocols are supported by Virtual Volumes? (Choose three.)

  • A. FCIP
  • B. FCoE
  • C. iSCSI
  • D. NFS v3
  • E. NFS v4

Answer: BCD

Explanation: Virtual Volumes supports NFS version 3 and 4.1, iSCSI, Fibre Channel, and FCoE.
