NEW QUESTION 31
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 initially support the concurrent running of 300 production and 600 development virtual machines.
The production environment should be delivered across two geographically dispersed data centers. The development environment must be vSphere-based but does not have to be deployed on-premises.
The two data centers are connected to each other through multiple diversely routed, high bandwidth and low latency links.
The customer's server hardware standard document states that all virtual infrastructure hosts must be based on blade architecture only.
The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities, such as the monthly software patching and ad-hoc hardware break/fix.
All virtual machine backups must be completed using the existing backup service. The recovery time objective (RTO) for the service is four hours.
The recovery point objective (RPO) of the service is 24 hours.
Given the information from the customer, which two would be classified as assumptions within the design? (Choose two.)
- A. The backup service will store data in a secure facility
- B. The clusters will have a minimum redundancy of N+1
- C. The backup service has sufficient capacity for the new requirements
- D. The customer will update their hardware standard to support rack mount servers
- E. All virtual machines will be deployed with the same resource profile for production and development
Answer: A,D
NEW QUESTION 32

- A. Virtual Guest Tagging (VGT)
- B. vSwitch VLAN Tagging (VST)
- C. Separate Distributed Virtual Switches (DVS)
- D. Private VLANs (PVLAN)
Answer: C

NEW QUESTION 36
During a requirements gathering workshop to design a physical to virtual migration, the customer provides the following information:
There is no physical firewall in the data center with no anticipated plans for a future network refresh.

- C. Split the virtual machines into several VLANs Use tag actions
- D. Disable traffic filtering and marking Use tag actions
Answer: C
NEW QUESTION 37
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. 90 minutes
