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

In a meeting to discuss the minimum viable product (MVP) deployment of a new customer-facing application, the key stakeholder shares details of the application components and the application administrators share details of performance and integrity tests for the application.

The application will be made up of the following components:

• A web server

-Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online.

• An application server

-Steps to confirm application server integrity will take 15 minutes after the database is online.

• A database server

-The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to restore and validate database services within one hour.

The existing VMware infrastructure offers a recovery point objective (RPO) of 5 minutes and recovery time objective (RTO) of 15 minutes through a combination of backups and replication.

In the event of an outage impacting all three application components, how long will it take for the application to recover and complete all checks?

An architect has 50 ESXi hosts to deploy and DHCP servers are not allowed on any network. Which automated host deployment method should the architect use?

A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.

What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?

An architect is designing a VMware solution for a customer to meet the following requirements:

• 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 32G fabric infrastructure.

Which design decision should the architect make to meet these requirements?

Refer to the exhibit.

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

The customer states that there is no application level availability for legacy applications.

Which recommendation could the architect make to meet the customer’s high availability requirements for the legacy applications virtual machines?

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.

Which requirement classification is being gathered for the design documentation?

An organization's existing vSphere environments are configured for Enhanced Linked Mode. The DevOps team automates the creation of hardened virtual machine images for various operating systems. Their continuous integration/continuous delivery (CI/CD) pipeline runs a task at the end of a successful build, which uploads the Open Virtualization Format (OV) image to a sandbox content library, deploys a virtual machine from the image, and then destroys these objects after quality checks are complete.

The following requirements have been noted:

• All content libraries and images must be centrally created and managed.
• All images must be capable of being updated.
• All images must be refreshed and available to subscribed libraries within 24 hours.
• All images must provide details of the image contents and versions.
• All images must be capable of being reverted to a previous version.
• All images must be capable of having the hardware and guest operating system customized during deployment.

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

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?

During a requirements gathering workshop, the customer provides the following requirement (REQ) and constraints (CON):

• REQ01: The customer is looking for a way to limit database virtual machine (VM) placement to save on CPU licensing costs.
• CON01: There is a single cluster with no budget to scale.
• CON02: All virtual machines must run on the consolidated cluster.

Which two design decisions should the architect make to meet the customer requirement? (Choose two.)

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 support the concurrent running of 1,000 virtual machines
• The production environment must be delivered across two geographically dispersed data centers All virtual machines must be capable of running in either data center.
• The two data centers are currently connected to each other through a single but diversely routed, high bandwidth and low latency link.
• The link between the two data centers is capable of supporting a round-trip time (RTT) of 150 ms The existing server hardware standard document states that all virtual infrastructure hosts must be deployed using vSAN ReadyNodes
• The service owner has stated that it is critical to ensure the availability target of 99.9% All virtual machine backups must be completed using the existing backup service
• The recovery time objective (RTO) for the service is five minutes
• The recovery point objective (RPO) of the service is four hours

Which two elements represent risks to the successful delivery of this solution? (Choose two.)

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

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?

Refer to the exhibit.

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

Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?

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.
• Leveraging the virtual infrastructure to mitigate the lack of network security must be addressed in the 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?

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?
