3V0-21.21 Online Practice Questions and Answers

Which two of the listed requirements would be classified as performance non-functional requirements? (Choose two.)

A. The vSphere platform must be able to provide a recovery time objective of 30 minutes

B. The vSphere platform must be able to provide a minimum throughput of 400 MB/s

C. The vSphere platform must be able to provide N+1 redundancy

D. The vSphere platform must be able to provide a maximum read latency of 15 ms

E. The vSphere platform must be able to provide a service-level agreement (SLA) of 99,9%

An architect is designing a new vSphere platform to meet a list of requirements from the security team.

Which two requirements would be classified as non-functional requirements? (Choose two.)

A. Migration of virtual machines between hosts must be encrypted

B. Log information must be verbose to support incident resolution

C. Critical events generated within the platform must be logged to an external Syslog service

D. Data integrity must be ensured

E. A common content library must be maintained across all data centers

An architect is finalizing the design for a new vSphere platform based on the following information:

All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes.

All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes.

All management virtual machines will be hosted on a dedicated cluster.

A total of ten physical sites will be used to host virtual machines.

In the event of one physical datacenter becoming unavailable, the manageability of the virtual

infrastructure in the remaining data centers should not be impacted.

Access to configure the management virtual machines via vCenter Server must be controlled through the

management Active Directory domain.

Access to configure the Windows and Linux virtual machines must be controlled through the resource

Active Directory domain.

The management and resource Active Directory domains are part of separate Active Directory forests and

do not have any trusts between them.

The design will use Active Directory with Integrated Windows Authentication.

How should the architect document the vCenter Server configuration for this design?

A. Deploy a vCenter server for the management cluster. Deploy a vCenter Server for all remaining clusters. Create a shared SSO domain for each physical site.

B. Deploy a vCenter Server for the management cluster. Deploy a vCenter Server for all remaining clusters. Create a shared SSO domain across all physical sites.

C. Deploy a vCenter Server for the management cluster with a dedicated SSO domain. Deploy a vCenter Server for all remaining clusters and use a dedicated SSO domain for each physical site.

D. Deploy a vCenter Server for the management cluster with a dedicated SSO domain. Deploy a vCenter Server for all remaining clusters and use a dedicated SSO domain into a single physical site.

An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.

An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.

In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)

A. %Ready

B. Disk Write latency

C. CPU

D. Ballooned memory

E. IOPS

Refer to the exhibit.

During a requirements gathering workshop, the customer shares the following about their existing ESXi

host virtual networking infrastructure:

The customer confirms that:

Each ESXi host has approximately 200 virtual machines.

They want to maximize the number of concurrent virtual machine migrations.

When placing a host in maintenance mode, it takes a long time to evacuate the virtual machines.

Which two recommendations should the architect make in order to help the customer overcome their

challenge? (Choose two.)

A. Configure the network to use MTU for the VMotion VMKernel to 1,600 bytes

B. Configure the network to use MTU for the VMotion VMKernel to 9,000 bytes

C. Create an additional standard switch with pNIC3 to use for vMotion

D. Use the 3 pNICs and bundle them in a link aggregation group (LAG) configuration

E. Use 10 GbE NICs instead of 1 GbE

A customer has six hosts available in a cluster. When running at full capacity, all virtual machines can be run on two hosts.

How many hosts can the customer place into maintenance mode at the same time while still providing N+2 resiliency to the cluster?

A. Two

B. Three

C. One

D. None

During a requirements gathering workshop, the customer provides the following requirement that is

pertinent to the design of a new vSphere environment:

The Maximum Tolerable Downtime (MTD) for all Tier 1 applications is one hour.

Which requirement classification is being gathered for the design documentation?

A. Manageability

B. Performance

C. Availability

D. Recoverability

As part of a requirements gathering workshop, the customer provides the following requirements for the

design of a new greenfield virtual infrastructure:

Some applications have a latency that must be less than 5 minutes.

The solution must be able to support a workload growth rate of 10% per year.

Which requirement classification is being gathered for the design documentation?

A. Performance

B. Manageability

C. Recoverability

D. Availability

Which of the listed requirements would be classified as a recoverability non-functional requirement?

A. The platform must be integrated with existing change control policies.

B. The platform must be able to support a maximum tolerable downtime (MTD) of 30 minutes.

C. Maintenance windows must be scheduled to take place monthly during an established overnight period.

D. The platform must be available 24 hours a day, 7 days a week with the exception of scheduled downtime.

Which requirement would be classified as a functional requirement within the application design documentation?

A. The application must be hosted with redundancy levels of N+1 or better.

B. Penetration testing must be executed quarterly with a pass rate of 80% or higher.

C. The application must be capable of handling 200 transactions per second.

D. Administrators must monitor the network traffic of the desired systems.
