In stretched clusters, what is a benefit of implementing a virtual witness rather than a physical witness?

A. Reduced vSphere licensing

B. Shared metadata between separate clusters

C. Increased vSAN datastore capacity

D. Increased compute for running VMs

An administrator is planning to deploy a new vSAN cluster with these requirements: -Physical adapters will share capacity among several traffic types -Guaranteed bandwidth for vSAN during bandwidth contention -Enhanced security and performance

What must be considered when configuring the new vSAN cluster?

A. Isolate traffic in a VLAN and utilize Network I/O Control

B. Utilize IOPS Limit rules in storage policies

C. Utilize jumbo frames with Network I/O Control

D. Implement vSphere I/O filters

A company implements a vSAN environment with linked clone virtual desktops and homogeneous desktop

operating systems. During the last three months, users have experienced intermittent high latency,

degraded performance, and lockout from desktops.

Which two methods should an administrator use to monitor and respond to the issues? (Choose two.)

A. vRealize Log Insight

B. vRealize Automation

C. Live Optics

D. HCIBench

E. vRealize Operations Manager

A vSAN administrator is designing a new all-flash vSAN cluster. The cluster will host read intensive

applications.

Which factor should be included in the design to improve read performance?

A. Multiple disk groups

B. Large capacity disks

C. Large cache disks D. Large controller cache

The cluster level backend IOPS performance graph shows a higher-than-average number of IOPS. What is a possible reason for this?

A. Data resynchronizations

B. Low volume of vSAN vital memory pools

C. DRS invoking multiple vMotion migrations

D. Destaging congestion

Which two factors should be considered when planning usable vSAN datastore capacity? (Choose two.)

A. Flash Read Cache Reservation percentage

B. Failure tolerance method

C. Stripe width

D. IOPS limit for object

E. Failures To Tolerate

An administrator wants to increase the capacity of a disk group cache device.

What is required to increase the cache device size?

A. Hot swap the disk group cache device.

B. Perform a storage vMotion between disk groups.

C. Put the disk group in maintenance mode and swap the cache device.

D. Recreate the disk group with a new cache device.

Which two group types are used to determine capacity breakdown in a vSAN datastore? (Choose two.)

A. network

B. CPU

C. data

D. memory

E. object

A vSAN administrator has three available racks and six vSAN hosts.

What can a vSAN administrator use to protect against a rack failure while maximizing resources?

A. explicit fault domain

B. vSAN stretched cluster

C. 2-node configuration

D. RAID-6/FTT=2

An administrator is designing a vSAN cluster for performance driven workloads.

Which design decision will provide more I/O paths to the vSAN cluster?

A. add cache devices to disk groups

B. add compute-only nodes

C. add disk groups to each host

D. add CPUs to each host
