1. An architect is designing an environment for a retail customer. The design will use a single small vCenter Server Appliance and a cluster of eight ESXi hosts at a remote site. There is a single 10 GbE connected network at the remote site to support all management services. It is not possible to create additional management networks at the remote site. Virtual machine backups at the site will be dependent on the vCenter Server being available.

Which design decision should the architect make to maximize availability for backups?

2. During a transformation project kick-off meeting, an architect highlights specific areas on which to focus while developing the new conceptual design.

Which two of the listed statements are business requirements? (Choose two.)

What should the architect consider when designing the number and type of clusters required?

4. The Chief Operating Officer (COO) at an organization raises concerns that their virtual infrastructure environment is vulnerable. Recently, a security-related issue with a virtual machine caused all management services to become unavailable. No budget is available in the short term for additional platform investment.

An architect is asked to review the current environment and make recommendations to mitigate concerns.

A virtualization administrator has provided the following details:

✑ There is a single four node cluster of ESXi servers

✑ There are two, Layer 2, physical network switches connecting resources

✑ The data center network is presented as a single /16 subnet

Given the information provided, which functional requirement should the architect include in the design to mitigate the COOs concerns?

5. Following a recent acquisition, the architect learns that both companies use vSphere on-premise and will need to combine the data centers into one. The acquired company's licenses will not be renewed for cost-savings related to the acquisition. All consumed vSphere licenses must have active support to support line-of-business operations. The merged environment must maintain 25% spare capacity. The architect has a small budget remaining unallocated for hardware.

The architect has calculated that the current vSphere environment can absorb the acquired company's virtual machines but the cluster will run at 90% memory utilization and at 50% CPU utilization.

Which design decision can the architect make to incorporate the new company's virtual machines into the combined vSphere environment?

6. An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services.

The platform has recently commissioned new hosts to update the development cluster.

The development cluster host configuration is:

✑ 4 ESXi hosts with 2 sockets × 16 cores

✑ 512 GB RAM divided evenly between sockets

✑ There is no resource contention

The benchmarking cluster host configuration is:

✑ 8 ESXi hosts with 2 sockets × 8 cores

✑ 256 GB RAM divided evenly between sockets

✑ There is no resource contention

The customer is developing an application that includes a database virtual machine.
