質問 2：
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 (SaaS) 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 Proalhazi@1tocol (PTP) 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. Set the virtual hardware device to use Host System Time (NTP) for each virtual machine running the application.
B. Add a precision clock virtual device to each virtual machine running the application.
C. Add a virtual watchdog timer (VWDT) device to each virtual machine running the application.
D. Configure the chrony time-sync agent on each virtual machine guest operating system.
E. Use a Linux distribution as the guest operating system.
F. Use Microsoft Windows Server as the guest operating system.

質問 6：
A Cloud Service Provider wants to introduce backup as a service for a customer's vSphere-based virtual machines.
The following information is noted:
They have a single four-port (2 × 10 GbE and 2 × 1 GbE) NIC per ESXi host All top-of-rack (ToR) switches are 10 GbE and fully populated The backup traffic must not impact existing services Which two recommendations should the architect make to help the customer incorporate the service? (Choose two.)
A. Add a new two-port 10 GbE NIC per ESXi host
B. Replace the existing NIC with a two-port 25 GbE NIC per ESXi host
C. Create a new virtual switch using the 1 GbE uplinks
D. Match the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the physical network
E. Enable and tag traffic on the backup distributed port group

質問 8：
An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.
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 RTT on the link between the two data centers
C. The use of vSAN ReadyNodes
D. The use of the existing backup service
E. The network connectivity between data center sites
正解：D,E

質問 9：
In a meeting to discuss the minimum viable product (MVP) deployment of a new customer-facing application, the key stakeholder shares details of the application components and the application administrators share details of performance and integrity tests for the application.
The application will be made up of the following components:
A web server
- Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online.
An application server
- Steps to confirm application server integrity will take 15 minutes after the database is online.
A database server
- The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to restore and validate database services within one hour.
The existing VMware infrastructure offers a recovery point objective (RPO) of 5 minutes and recovery time objective (RTO) of 15 minutes through a combination of backups and replication.
In the event of an outage impacting all three application components, how long will it take for the application to recover and complete all checks?
A. 60 minutes
B. 15 minutes
C. 105 minutes
D. 90 minutes
