88.A new real-time financial service application is being developed by the engineering team at a financial firm and will be released as a public Software-as-a-Service ( ) offering. The solutions architect has designed and deployed a new vSphere environment and the supporting network infrastructure for hosting all public services. ESXi hosts are configured to use Precision Time Protocol ( ) and a local stratum-1 network time server. Application provisioning and scaling will be managed by VMware vRealize Automation and can be run on Microsoft Windows or multiple distributions of Linux.
Which three recommendations should the architect include in the design to ensure that the service maintain timekeeping within an accuracy of one second? Choose three.

A. 　 The vMotion service must be configured on the Management VMkernel adapter

B. 　 A dedicated TCP/IP stack for vMotion with a dedicated gateway must be configured

C. 　 A stretched vMotion network must be configured between data centers

D. 　 Virtual machines must be powered off in order to migrate them between data centers

A. 　 The number of vSphere hosts in a cluster

B. 　 The average resource utilization of a virtual machine

C. 　 The size (CPU/RAM/storage) of the average virtual machine

D. 　 The guest operating system for each virtual machine

E. 　 The size (CPU/RAM/storage) of the vSphere hosts

A. 　 A new subnet will be provisioned for vCenter HA services

B. 　 A vSphere cluster will consist of more than three nodes

C. 　 The deployed vCenter Server will be Tiny

D. 　 The vCenter HA network will support a latency of less than 50 ms

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. 　 It focuses on functional requirements with C-level stakeholders

B. 　 It leverages a single set of questions for all stakeholders

C. 　 It might require multiple rounds of stakeholder interviews

D. 　 It builds stakeholder consensus

E. 　 It is a non-iterative process

REQ01: The customer is looking for a way to limit database virtual machine (VM ) placement to save on CPU licensing costs.

CON01: There is a single cluster with no budget to scale.

CON02: All virtual machines must run on the consolidated cluster.

Which two design decisions should the architect make to meet the customer requirement? Choose two.

A. 　 The solution must use VM-VM anti-affinity rules

B. 　 The solution must use vSphere DRS in manual mode

C. 　 The solution must use a vRealize Orchestrator workflow for VM placement

D. 　 The solution must use VM-Host affinity rules

E. 　 The solution must use vSphere VM and host DRS groups

A. 　 Separate Tier-1, Tier-2 and Tier-3 virtual machines using dedicated distributed virtual switches (DVS)

B. 　 Separate Tier-2 virtual machines onto a dedicated cluster

C. 　 Separate Tier-1, Tier-2 and Tier-3 virtual machines onto dedicated clusters

D. 　 Separate Tier-1, Tier-2 and Tier-3 virtual machines using resource pools and shares

A. 　 Migrate the acquired company's virtual machines into the vSphere environment as it will currently fit.

B. 　 Use the current budget to add memory to the cluster to increase each ESXi host's capacity and add the new virtual machines.

C. 　 Purchase extra hosts to add to the cluster in anticipation of adding the acquired company's virtual machines.

D. 　 Purchase new licenses for some of the acquired company's ESXi hosts and add them to the cluster to hold the acquired company's virtual machines.

A. 　 Use Storage DRS.

B. 　 Use VMDK anti-affinity rules.

C. 　 Use multiple datastores for heartbeat.

D. 　 Use a minimum of three storage arrays.

E. 　 Use VM to host DRS rules.

A. 　 Use Microsoft Windows Server as the guest operating system.

B. 　 Configure the chrony time-sync agent on each virtual machine guest operating system.

C. 　 Set the virtual hardware device to use Host System Time (NTP) for each virtual machine running the application.

D. 　 Add a precision clock virtual device to each virtual machine running the application.

E. 　 Use a Linux distribution as the guest operating system.

F. 　 Add a virtual watchdog timer (VWDT) device to each virtual machine running the application.
