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 isconsidering 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 datastoreson 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 environmenthas 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.

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 ChannelAdapter.

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

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 followingeffects:
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.

Where must the VMware vSphere Storage Appliance Manager (VSA Manager) be installed?
On a Windows virtual machine created on the first VSA host
The VSAManager 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.

Using the vSphere Storage Appliance (VSA) Manager to view the Appliances Status column, what are three valid states? (Choose three.)
Question No: 129 – (Topic 3)
A virtual machine requires a 4TB disk for application data. The storage administrator has already created and presented a 4TB LUN to an ESXi 5.x host. The host is currently configured with a single 500GB VMFS5 datastore.
What is the next step the vSphere administrator must use to provision the data disk?
Create a virtual compatibility mode RDM mapping to the 4TB LUN.
Create a physical compatibility mode RDM mapping to the 4TB LUN.
Expand the existing VMFS volume to 4TB. Create a physical compatibility mode RDM mapping to the 4TB LUN.
Expand the existing VMFS volume to 4TB. Create a virtual compatibility mode RDM mapping to the 4TB LUN.
Question No: 130 – (Topic 3)
Which two statements are true about shared storage capabilities on NFS datastores supported by ESXi 5.x? (Choose two.)
You can create Fault Tolerant virtual machines
You can mount up to 256 NFS datastores
You can use VMware Storage APIs with all NFS datastores
You can use Storage vMotion from a virtual-mode RDM
