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

The Chief Information Security Officer (CISO) for an organization is concerned about the security posture of the operating system images that are used for the provisioning of their Software-as-a-Service (SaaS) applications. The organization is in a growth period. The organization is opening a new data center to launch its next phase of new SaaS-based solutions.

The DevOps team currently creates encrypted virtual machine (VM) templates that are used for various operating systems and adds these to the vSphere inventory. The DevOps team already uses a published content library and has been granted a role with the ability to add and delete library items.

The following requirements have been noted:

• Impacts to the DevOps team’s operational processes must be kept to a minimum.
• The DevOps team must be able to regularly check out a copy of the image for updates and check in a new version of the image.
• Images must be synchronized from the primary data center to the new data center.

Which three recommendations should the architect make to design a content library solution that will meet these requirements? (Choose three.)

During a requirements gathering workshop, the customer shares the following diagram regarding their availability service-level agreements (SLAs):

The customer wants database application level availability to always take precedence. What should the architect recommend to meet the customer’s requirement?

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 preparing a design for a customer. Based on requirements, the architect recommends an HCI- based infrastructure with all-flash architecture. During the assessment, it is confirmed that the network throughput generated by virtual machines does not exceed 150 Mb/s.

What is the minimum number and type of network adapters in each server that the architect can recommend to ensure requirements are met and there is no single point of failure?

An architect is tasked with expanding an existing VMware software-defined data center (SDDC) solution so that it can be used to deliver a virtual desktop infrastructure (VDI) service off-shore development activities.

The production environment is currently delivered across two geographically dispersed data centers. The two data centers are currently connected to each other through multiple diversely routed, high bandwidth and low latency links. The current operations management components are deployed to a dedicated management cluster that is configured with N+1 redundancy. The current VMware software-defined data center (SDDC) has a monthly availability target of 99.5%, which includes all management components.

The customer requires that the new solution scale to support the concurrent running of 500 persistent virtual desktops. The virtual desktops must not share the same virtual infrastructure as existing virtual machines, but can be managed using the same VMware operations management components. Any new VDI service management components must be installed into the management cluster. There is no requirement to back up the virtual desktops because all relevant user data is stored centrally. The VDI service is providing business critical services and must have an availability target of 99.9%.

Given the information from the customer, which two assumptions would the architect include in the design? (Choose two.)

A customer has a database cluster with 40/60 read/write ratio and a high IOPs requirement with no contention on an all-flash vSAN cluster.

Which two storage settings should be configured for best performance? (Choose two.)

An architect is designing a new greenfield environment with 600 ESXi hosts in an automated fashion. The engineering department already has a PXE Boot server, TFTP server, and DHCP server set up with an NFS mount for their current Linux servers.

The architect must be able to demonstrate and meet a security requirement to have all infrastructure processes separated.

Which recommendation should the architect make for the ESXi host deployment?

Following a company merger, there are two data centers running vSphere environments. Both data centers are leveraging separate Layer 3 vMotion networks.

Which requirement must be met in order to enable vMotion migration between these locations?

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?

Which requirement would be classified as a functional requirement within the application design documentation?

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 requires the use of data encryption to ensure data is not accessible when a drive is removed from the primary storage platform. However, there is also a requirement to use deduplication and compression against all workloads in order to conserve space.

Which solution meets the customer requirements?

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?

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 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?

An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:

• REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.
• REQ02 The infrastructure must initially run 100 virtual machines.
• REQ03 Ten of the virtual machines must be compliant with internal security standard.
• REQ04 The internal security standard specifies logical network separation for in-scope applications.
• CON01 The customer has already purchased the licenses as part of another project.
• CON02 The customer has five physical servers that must be reused.

Additionally, based on resource requirements, four physical servers will be enough to run all workloads. Which recommendation should the architect make to meet requirements while minimizing project costs?

During a requirements gathering workshop, the customer’s Chief Information Security Office (CISO) provides the following requirements that are pertinent to the design of a new vSphere environment:

• All operating system critical patches must be installed within 24 hours of release.
• All virtual machine templates must be updated every three months in line with company policy.

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?

An architect is tasked with recommending a solution for a company that is running out of VLANs. Currently the company is running two separate data centers based on vSphere including an Enterprise Plus license. In the first data center, the problem was solved by using VMware NSX and overlay network. In the second data center, there is currently no VMware NSX implementation in place and no budget for additional licenses.

What should the architect recommend as a potential solution to provide support for additional VLANs?
