3V0-21.21 Advanced Design VMware vSphere 7.x Questions and Answers

An architect is planning the physical server configuration for a vSAN-based infrastructure.

Which operations mode should a RAID controller support to minimize potential server downtime during physical disk failures?

An architect is reviewing a physical storage design. The customer has specified that a new active-passive based storage array will be used to provide storage for the vSphere clusters.

Which configuration should for the architect recommended?

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.

Which single sign-on (SSO) design recommendation will meet these requirements?

An architect is finalizing the design for a new vSphere platform based on the following information:

• All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes.
• All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes. All management virtual machines will be hosted on a dedicated cluster.
• A total of ten physical sites will be used to host virtual machines.
• In the event of one physical datacenter becoming unavailable, the manageability of the virtual infrastructure in the remaining data centers should not be impacted.
• Access to configure the management virtual machines via vCenter Server must be controlled through the management Active Directory domain.
• Access to configure the Windows and Linux virtual machines must be controlled through the resource Active Directory domain.
• The management and resource Active Directory domains are part of separate Active Directory forests and do not have any trusts between them.
• The design will use Active Directory with Integrated Windows Authentication.

How should the architect document the vCenter Server configuration for this design?

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?

A customer has six hosts available in a cluster. When running at full capacity, all virtual machines can be run on two hosts.

How many hosts can the customer place into maintenance mode at the same time while still providing N+2 resiliency to the cluster?

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.

Which design recommendation should the architect make for distributing the resource profiles?

During a requirements gathering workshop, the customer provides the following requirement that is pertinent to the design of a new vSphere environment:

• The Maximum Tolerable Downtime (MTD) for all Tier 1 applications is one hour.

Which requirement classification is being gathered for the design documentation?

An architect is designing a VMware solution for a customer based on the following information:

• The solution must use investments in existing storage array that supports both block and file storage.
• The solution must support the ability to migrate workloads between hosts within a cluster.
• The solution must support resource management priorities.
• The solution must support the ability to connect virtual machines directly to LUNs.
• The solution should use existing IPv4 based network infrastructure.
• There is no budget for additional physical hardware.

Which two design decisions could the architect make to meet these requirements? (Choose two.)

An architect is tasked with designing a new VMware software-defined data center (SDDC) solution for an online retail customer who has a primary and secondary data center as well as 10 distribution hubs.

The customer has provided the following business requirements to help inform the design:

• The solution must support the running of up to 1,000 concurrent virtual machines across the primary and secondary data center.
• The solution must support the running of up to 20 concurrent virtual machines in each distribution hub.
• The solution must support the separation of management and lines-of-business application virtual machines.
• All management components (including directory services, backup, automation, operations and logging) must be deployed to the primary data center.
• All virtual infrastructure components must have redundancy of N+1.
• All sites are connected to each other using a wide area network that has multiple diversely routed links.
• The solution should support a monthly uptime target of 99.9%.
• The recovery time objective (RTO) for the solution must be four hours.
• The recovery point objective (RPO) for the solution must be 24 hours.

Given the information from the customer, which assumption should the architect include in the design?
