22.An architect is tasked with reviewing the design of a VMware software-defined data center ( ) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster.The development cluster host configuration is:
--4 ESXi hosts with 2 sockets × 16 cores
--512 GB RAM divided evenly between sockets
--There is no resource contention
--The benchmarking cluster host configuration is:
--8 ESXi hosts with 2 sockets × 8 cores
--256 GB RAM divided evenly between sockets
--There is no resource contention
--The customer is developing an application that includes a database virtual machine、 The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data
What is a possible reason for the difference in performance test results between the development and benchmarking clusters?

A. 　 The load balancing algorithm used by the Management Distributed Virtual Switches (DVS)

B. 　 The SSH configuration settings for the vCenter Server’s active node

C. 　 The vCenter Management Network IPv4 addresses for the witness node vCenter Server

D. 　 The details of each of the vCenter Server licenses for active, passive and witness nodes

A. 　 Clone virtual machines as VM templates to the published content library

B. 　 Create a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates on-demand

A. 　 Use Network I/O Control to define a reservation for vMotion traffic.

B. 　 Implement Multi-NIC vMotion by adding additional vMotion VMkernels.

C. 　 Configure a dedicated TCP/IP stack for vMotion traffic.

D. 　 Combine vMotion and Management traffic to make use of four adapters.

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%

A. 　 Site Recovery Manager

B. 　 Snapshots

C. 　 vSAN Metro Cluster

D. 　 vSphere Data Protection

E. 　 vStorage APIs for Array Integration (VAAI)

A. 　 vCenter Server High Availability will be configured.

B. 　 The vCenter Server Appliance will be protected with vSphere Fault Tolerance.

C. 　 The cluster will be configured to use vSphere DRS in fully automated mode.

D. 　 The cluster will be configured with vSphere HA and set to restart virtual machines based on guest operating system heartbeat monitoring.

During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:

The solution must support the concurrent running of 1,000 virtual machines.

The production environment must be delivered across two geographically dispersed data centers.

All virtual machines must be capable of running in either data center.

The two data centers are currently connected to each other through a single but diversely routed, high bandwidth and low latency link.

The link between the two data centers is capable of supporting a round-trip time (RTT) of 150 ms.

The existing server hardware standard document states that all virtual infrastructure hosts must be deployed using vSAN ReadyNodes.

The service owner has stated that it is critical to ensure the availability target of 99.9%.

All virtual machine backups must be completed using the existing backup service.

The recovery time objective (RTO) for the service is five minutes.

The recovery point objective (RPO) of the service is four hours.

Which two elements represent risks to the successful delivery of this solution? Choose two.

A. 　 The use of only two data centers

B. 　 The network connectivity between data center sites

C. 　 The use of vSAN ReadyNodes

D. 　 The RTT on the link between the two data centers

E. 　 The use of the existing backup service

A. 　 The system must perform virtual machine backups through an API.

B. 　 Virtual machines must be patched within one month of the patch release date.

C. 　 Virtual machines must be restarted within 30 minutes of a host failure.

D. 　 The system must be able to scale to support 500 concurrent virtual machines.
