NEW QUESTION # 34
An architect is designing a new vSphere platform for a customer to meet the following requirements:
The platform must be deployed into five physically separate sites.
The sites are spread across multiple regions.
Some sites require more than one vCenter Server.
The platform must provide an administrator with the ability to access virtual infrastructure components across all sites from a single management tool instance.

NEW QUESTION # 35
An architect is finalizing the design for a new vCenter Server High Availability deployment.
What is one thing the architect must document in the design?

• A. The load balancing algorithm used by the Management Distributed Virtual Switches (DVS)
• B. The details of each of the vCenter Server licenses for active, passive and witness nodes
• C. The vCenter Management Network IPv4 addresses for the witness node vCenter Server
• D. The SSH configuration settings for the vCenter Server's active node

Answer: D

Explanation:
vCenter HA uses SSH keys for password-less authentication between the Active, Passive, and Witness nodes. The authentication is used for heartbeat exchange and file and data replication. To replace the SSH keys in the nodes of a vCenter HA cluster, you deactivate the cluster, generate new SSH keys on the Active node, transfer the keys to the passive node, and activate the cluster.

NEW QUESTION # 41
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 has sufficient capacity for the new requirements
• B. The backup service will store data in a secure facility
