VMware 3V0-624 Exam Questions Instant Access

Question 1

A customer uses servers without internal storage and asks a systems architect to design a solution with a Fiber Channel array and blade servers as options. The customer requires:

* Easier server replacement

* Booting through HBA or FCoE

* Less wasted space

* Improved management

* Better reliability

* Inexpensive servers

* Easier backup processes

Which design element will follow VMware recommended best practices and also meet customer requirements?

AVMware Virtual SAN

BAuto Deploy

CPXE boot

DBoot from SAN

Answer : D

Question 2

Which two types of workloads are efficiently consolidated when virtualized? (Choose two.)

AWorkloads that do NOT require user input and are constantly processing large amounts of batched data.

BWorkloads that will consume all available assigned resources.

CWorkloads that are NOT CPU bound; most of their time is spent waiting for external events such as user interaction.

DWorkloads that do NOT require access to specific physical resources such as a hardware dongle or graphics card.

Answer : C, D

Workloads that are constantly using resources would prevent other VMs from accessing them, causing performance issues. Instead, if they use little and spend time waiting then resources are available for other VMs. Access to physical resources would prevent major virtualization benefits like HA etc.

Question 3

A customer is using a vSphere APIs for Storage Awareness (VASA) compatible storage array. The VASA provider is published as a virtual appliance.

To ensure recoverability, where must the VASA provider and vCenter server virtual machines be stored?

AThe VASA provider and vCenter Server will be placed on the standard datastore (VMFS, NFS).

BThe VASA provider and vCenter Server will be placed on the vVol datastore.

CThe vCenter Server will be placed on the vVol datastore and the VASA provider will be placed on the standard datastore (VMFS, NFS).

DThe VASA provider will be placed on the vVol datastore and the vCenter Server will be placed on the standard datastore (VMFS, NFS)

Answer : A

A VASA VM should definitely not run on a vVol as it is then dependent on itself. Similarly, the VASA VM is dependent on vCenter, so both should be kept on a standard VMFS or NFS volume. If you have vCenter on a vVol, and both VASA VM and vCenter go down you are SOL.

''You should not run VASA Provider on a VVOL datastore. Any management operation, including powering on a virtual machine that is on a VVOL, requires that VASA Provider be running. In addition, you would lose access to all VVOLs because VASA Provider would not be able to boot.''

Question 4

A company wants to use All-Flash vSAN as storage for its virtual environment on six hosts. When creating the storage policies for the virtual machine, this company requirements are:

* The virtual machine data must be available in the event of 2-node failure.

* The virtual machine will use as little overhead as possible.

* The virtual machine will be allocating 50GB of 100GB, configured upon creation.

To meet these requirements, what does the storage policy look like?

ANumber of failures to tolerate = 1 Object space reservation = 50% Disable object checksum = No Failure tolerance method = RAID 5/6

BNumber of failures to tolerate = 2 Object space reservation = 50% Disable object checksum = Yes Failure tolerance method = RAID 5/6

CNumber of diskstripes per object = 2 Object space reservation = 10% Flash read cache reservation = 50% Failure tolerance method = RAID 5/6

DNumber of failures to tolerate = 2 Object space reservation = 10% Flash read cache reservation = 50% IOPS limit for object = 1000

Question 5

A customer is deploying a mission-critical Oracle database with high SLA requirements, including high performance and high availability. The customer has chosen to purchase an All-Flash vSAN solution.

Which three storage policies should be used? (Choose three.)

ARAID5/6 for data disk and RAID1 for OS disk with FTT=2

BIOPS limit and checksum should be enabled.

CRAID5/6 for OS disk and RAID1 for data disk with FTT=2

DConfigure multiple disk stripes.

EDeduplication and Compression should be disabled.

Answer : C, D, E

A) RAID 5/6 should be used for capacity, not performance (good for normal use case, but here high performance are required)

B) IOPS limit should be enabled as switching path every few IO improve performance and reduce downtime should a path fail

C) RAID 1 preferred over RAID 5/6 for performance

D) While having multiple disk stripes might generally improve performance, this is not the case with Oracle

E) Dedup and compression are good for capacity, but impact performance

The link provided by Todd adds some more info, although his answer can't be correct (it can't be both A and C).Some extra info here: https://storagehub.vmware.com/t/vmware-vsan/oracle-database-on-vmware-vsan-6-7/

Question 6

What topics need to be considered when creating a storage design?

AApplication I/O requirements

BGrowth rate

CLatency

DAll of the above

Answer : D

Question 7

A customer has these requirements for storage:

* Protocol used must have a file-based access.

* Protocol used must have built in native multipathing.

* Protocol used must support authentication.

To meet these requirements, which protocol should be used for storage?

ANFS v3

BNFS v4.1

CFCoE

DiSCSI

Answer : B

Because NFS 4.1 are support authentication and is a file-based storage
