An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.

across all sites from a single management tool instance.

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 backup service has sufficient capacity for the new requirements

C. The customer will update their hardware standard to support rack mount servers

E. The clusters will have a minimum redundancy of N+1

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.

design.

All physical servers to be migrated exist on the same VLAN.

Which recommendation should the architect make to address the customer requirement with regard to

virtual networking?

A. Split the virtual machines into several VLANs Use tag actions

B. Create port groups with different names and same VLAN IDs Enable traffic shaping for ingress and egress traffic

C. Enable traffic filtering and marking Use allow or drop actions

D. Disable traffic filtering and marking Use tag actions
