An administrator plans to deploy ESXi 5.x on a blade server containing no local disks. What boot options are supported for use in place of local disks? (Choose three.)
An SD card
A NIC with iBFT
A server with IPMI or iLO
A dedicated NFS share

Which two storage adapters require no VMkernel ports? (Choose two.)
Independent Hardware iSCSI Adapter
iSCSI Software Adapter
Dependent iSCSI Adapter
Fibre Channel HBA
Answer: A,D Explanation:
Independent hardware iSCSI adapter and Fibre Channel HBA don’t need VMkernel ports.
Independent hardware iSCSI adapter implements its own networking and management interfaces. All configuration such as IP management, MAC addressing and other parameters are completely separate from VMware.

When a virtual machine interacts with persistent thick virtual disks stored on a traditional Fibre Channel storage array, which two actions are always taken by the VMkernel? (Choose two.)
The file corresponding to the virtual machine is located on the VMFS datastore using NPIV.
Correlate the blocks requested by the virtual machine with the actual blocks on the array.
Send the I/O request through the device driver to the physical HBA or software FCoE adapter.
Place an atomic lock on the metadata database for the VMFS volume.

Question No: 124 – (Topic 3)
Which options would reduce the load on the VMkernel when connecting to an iSCSI array? (Choose two.)
Use an independent hardware iSCSI adapter
Use a Converged Network Adapter
Enable the software iSCSI adapter
Use a dependent hardware iSCSI adapter
Answer: A,D Explanation:
Since independent hardware iSCSI adapter doesn’t need a VMkernel port, and it uses all its networking and management interfaces all by itself, it will significantly reduce the load
on VMkernel. Similarly, dependent iSCSI adapter use very little resources and hence can reduce the load off VMkernel.

ACME Tools has a vSphere 5.x deployment with an older iSCSI storage array. The administrator is considering adding an additional array, which will include support for the vStorage APIs for Array Integration (VAAI).
Which two tasks would be completed in a reduced period of time if the new array was added? (Choose two.)
creating VMFS datastores on the new array
creating fault tolerant virtual machines on the new array
migrating virtual machines using Storage vMotion between the arrays
writes to thin provisioned virtual disks on the new array

A vSphere 5.x environment has an ESXi 5.x host configured to boot from a hardware independent iSCSI adapter.
What is the expected outcome if the administrator attempts to disable the iSCSI HBA in the vSphere client?
The adapter will be disabled, but is re-enabled the next time the host boots up.
The adapter will be disabled and the host will not boot the next time the host boots up.
A hardware independent iSCSI adapter cannot be disabled from the vSphere Client.
The adapter will be enabled, but the host will boot into troubleshooting mode the next time the host boots up.

Question No: 127 – (Topic 3)
How does a hardware FCoE Adapter appear to an ESXi host?
As an uplink adapter attached to a vSphere Distributed Switch.
As a hardware FCoE Adapter.
As an enabled FCoE software initiator.
As a Fibre Channel Adapter.

Question No: 128 – (Topic 3)
What two statements are true about Fibre Channel zoning? (Choose two.)
Zones define paths to a Fibre Channel array
Zones control access to LUNs on a Fibre Channel storage array
Zones can be soft or hard
Zones can be configured on an array or ESXi host
Reference: http://pubs.vmware.com/vsphere- 51/index.jsp?topic=/com.vmware.vsphere.storage.doc/GUID-E7818A5D-6BD7- 4F51-B4BA-EFBF2D3A8357.html
Question No: 129 – (Topic 3)
What are two requirements when configuring a Fibre Channel SAN with an ESXi 5.x cluster? (Choose two.)
RDMs must be zoned and masked to each ESXi 5 host in the cluster
A FCP HBA or hardware supporting FCoE must be installed in the hosts
Each LUN should contain only one NFS datastore.
Each LUN must present a unique LUN ID to each ESXi hosts.
Explanation: A: correct because yes, you have to Zone and mask to allow only the Hosts in that you want in.
Zoning has the following effects:
Reduces the number of targets and LUNs presented to a host.
Controls and isolates paths in a fabric.
Can prevent non-ESXi systems from accessing a particular storage system, and from possibly destroying
Can be used to separate different environments, for example, a test from a production environment.
B: correct because yes you need HBAs to connect to the FC. C is obviously wrong as the FS is VMFS not NFS
D is wrong because: Page 37 of the vSphere storage guide says.
– For multipathing to work properly, each LUN must present the “same” LUN ID number to all ESXi hosts.
Question No: 130 – (Topic 3)
Where must the VMware vSphere Storage Appliance Manager (VSA Manager) be
On a Windows virtual machine created on the first VSA host
The VSA Manager is deployed as a separate virtual appliance
On a vCenter Server outside of the VSA environment
It is pre-installed on the VMware vSphere Storage Appliance
Answer: C Explanation:
VMware vsphere storage appliance manager is always installed on a vcenter server that resides outside of VSA environment.
