vSphere Storage

How does the VMkernel perform storage virtualization functions? (Choose two.)

By offloading the storage operations to the storage array By scheduling of I/O requests from multiple virtual machines

By accessing files on a VMFS or NFS file system as if they were FC devices By implementing multipathing that is managed by PSA 12 A:

Allows multiple remote systems to connect to a shared file system. Allows volumes to be accessed simultaneously by multiple ESXi hosts.

What are the features offered by an NFS file system in a storage architecture? (Cho

Enables High Availability to automatically restart virtual machines on separate hEnables clustering of virtual machines across different hosts.

What are the functions of multipathing? (Choose two.) 12 A:

Path Failover Load Balancing

Honoring of Share Values Scheduling I/O Requests

By default, ESXi uses only one VMDK NIC as egress or traffic-out port to connect to eac

A:

True False

Which framework translates the storage requirements expressed in a virtual machine storinto virtual machine granular provisioning capabilities? A:

234 A:

It can be reserved only for a specific VMDK in a Flash Read Cache pool.

It is placed directly in the virtual machine’s virtual disk data path.

It enhances the performance of virtual machines without modifying applications and OSs.

It is compatible with vSphere features such as vSpherevMotion and vSphere DRS.

It can be created when a virtual machine is either powered on or powered off.
