Demo Questions

Question 1
An administrator needs to monitor traffic on vSwitches in a vSphere 6.x environment. 
Which option, if configured, would accomplish this task?

  • A: Forged Transmits
  • B: MAC Address Changes
  • C: Promiscuous Mode
  • D: Notify Switches
Correct Answer: C
To monitor traffic via VMware Service Console (SC), a port group and a vswif interface with security settings modified to promiscuous mode accept is required for capturing.

Question 2
Which two actions allow for the disabling of Network Rollback operations? (Choose two.)

  • A: Modifying the vpxd advanced configuration options and adding the config.vpxd.network.rollback key
  • B: Modifying the C:\ProgramData\VMware\CIS\cfg\vmware-vpx\vpxd.cfg file and adjusting the<rollback> xml tag
  • C: Modifying the C:\ProgramData\VMware\CIS\cfg\vmware-vpx\vpxd.cfg file and adjusting the <networkrollback> xml tag
  • D: Modifying the C:\ProgramData\VMware\CIS\cfg\vmware-vpx\firstboot\vpxd-service-spec.prop file and adjusting the <rollback> xml tag
Correct Answer: AB
Modifying the vpxd advanded configuration options and adding the config.vpxd.network.rollback key. You can also modify the C:\ProgramData\VMware\CIS\cfg\vmware-vpx\vpxd.cfg file and adjusting the<rollback> xml tag

Question 3
What are two ways to identify TCP/IP stack information? (Choose two.)

  • A: Using the vSphere Web Client
  • B: Using esxcli network ip netstack
  • C: Using esxcfg-netstack
  • D: Using the vSphere Client
Correct Answer: AB
Use vSphere web client or the command esxcli network ip netstack to identify TCP/IP stack info. 
Reference: https://virtualizationreview.com/articles/2015/10/26/configure-multiple-tcpip-stacks-in-vsphere-6.aspx



Question 4
Which two Fibre Channel zoning options are supported with vSphere 6.x? (Choose two.)

  • A: Single-Initiator
  • B: Single-Initiator-Single-Target
  • C: Multiple-Initiators-Single-Target
  • D: Multiple-Initiators-Multiple-Targets
Correct Answer: AB
Use single-initiator-single-target zoning when zoning ESXi hosts to Fibre Channel arrays. With this type of configuration, fabric related events that occur on one array do not impact other arrays

Question 5
Which two parameters are required when adding an iSCSI target to an iSCSI Software Adapter using Dynamic Discovery? (Choose two.)

  • A: The iSCSI device's IP Address or Fully Qualified Domain Name
  • B: The Port Number
  • C: The iSCSI device's iSCSI Qualified Name (IQN)
  • D: The Default Gateway IP Address
Correct Answer: AB
When adding an iSCSI target to an iSCSI software adapter using dynamic discovery, use iSCSI device IP address or FQDN. You can use port number to add iSCSI too. 
Reference: https://pubs.vmware.com/vsphere-50/topic/com.vmware.vcli.examples.doc_50/cli_manage_iscsi_storage.7.5.html



Question 6
What is true regarding datastores on ESXi 6.x?

  • A: NFS 4.1 datastore does not support Fault Tolerance (FT)
  • B: Both VMFS3 and VMFS5 datastores can be created
  • C: NFS datastore can be mounted using NFS 4.1 on one ESXi host and NFS 3.0 on another
  • D: NFS 3.0 datastore does not support Fault Tolerance (FT)
Correct Answer: A
VMs on NFS v4.1 support FT, as long as it is the new FT mechanism introduced in 6.0. 
VMs running on NFS v4.1 do not support the old, legacy FT mechanism. 
In vSphere 6.0, the newer Fault Tolerance mechanism can accommodate symmetric multiprocessor (SMP) virtual machines with up to four vCPUs. Earlier versions of vSphere used a different technology for Fault Tolerance (now known as legacy FT), with different requirements and characteristics (including a limitation of single vCPUs for legacy FT VMs).

Question 7
Which type of Adapter does not require vmkernel networking?

  • A: Independent Hardware iSCSI Adapter
  • B: Dependent Hardware iSCSI Adapter
  • C: Software iSCSI Adapter
  • D: Software FCoE Adapter
Correct Answer: A
Independent Hardware iSCSI adapter does not require vmkernel networking.

Question 8
What are two benefits of using NFS 4.1 with vSphere 6.x as compared to NFS 3? (Choose two.)

  • A: NFS 4.1 supports Kerberos Authentication
  • B: NFS 4.1 supports multipathing
  • C: NFS 4.1 supports IPv6
  • D: NFS 4.1 supports hardware acceleration
Correct Answer: AB
NFs 4.1 support kerberos authentication and multipathing.

Question 9
Which two storage controller configurations can be used with Virtual SAN? (Choose two.)

  • A: SAS controllers in Passthrough mode
  • B: SAS controllers in RAID0 mode
  • C: SAS controllers in RAID1 mode
  • D: SAS controllers in RAID10 mode
Correct Answer: AB
SAS controllers in passthrough mode and in RAID 0 mode can be used with virtual SAN. 
Reference: http://blogs.vmware.com/vsphere/2014/01/virtual-san-hardware-guidance-part-ii-storage-controllers.html



Question 10
A company has decided to implement Virtual SAN within their vSphere 6.x environment. The Virtual SAN cluster will be composed of three ESXi 6.x hosts that are on the Virtual SAN Ready Node list.    
Each ESXi host includes:
Two SAS Controllers that support Passthrough Mode 
Four Solid State Drives (SSDs) 1TB in size each 
20 SAS Magnetic Disks (MDs) 1TB in size each 
The SSDs and MDs are evenly split between the two SAS controllers   
The company will pilot a Virtual SAN cluster utilizing VMware best practices while maximizing storage capacity. The Virtual SAN cluster will use Manual Mode. 
Which two Disk Group configurations would meet the stated configuration requirements? (Choose two.)

  • A: 4 disk groups with 1 SSD and 5 MDs each
  • B: 2 disk groups with 1 SSD and 7 MDs each
  • C: 2 disk groups with 2 SSDs and 7 MDs each
  • D: 2 disk groups with 1 SSD and 10 MDs each
Correct Answer: AB
4 disk groups with 1 SSD and 5 Mds each and 2 disk groups with 1 SSD and 7 Mds each can meet the configuration requirements in the scenario.
