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

A customer requests a review of its current vSphere platform design. The following information is noted: There are three different workload profiles for the virtual machines: Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM. Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks. Tier-3 virtual machines operate platform management tools such as vCenter Server and have different lifecycle management requirements. Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster. The Chief Information Security Officer (CISO) has raised concerns that hosting externally facing applications alongside management tools does not meet internal compliance standards. The Operations team has raised concerns about Tier-1 virtual machines negatively impacting the performance of vCenter Server. The Operations lead has stated that management changes have consistently been rejected by application teams. As a result of the review, which recommendation should the architect make regarding the design of this platform?

• AA. Separate Tier-1, Tier-2 and Tier-3 virtual machines using dedicated distributed virtual switches (DVS)
• BB. Separate Tier-2 virtual machines onto a dedicated cluster
• CC. Separate Tier-1, Tier-2 and Tier-3 virtual machines onto dedicated clusters
• DD. Separate Tier-1, Tier-2 and Tier-3 virtual machines using resource pools and shares

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?

• AA. Enable vSphere HA and add a VM Override with VM Restart Priority set to Disabled
• BB. Enable Fault Tolerance
• CC. Achieve application availability with snapshots
• DD. Enable vSphere HA and add a VM Override with VM Restart Priority set to Lowest

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?

• AA. vCenter Server High Availability will be configured.
• BB. The vCenter Server Appliance will be protected with vSphere Fault Tolerance.
• CC. The cluster will be configured to use vSphere DRS in fully automated mode.
• DD. The cluster will be configured with vSphere HA and set to restart virtual machines based on guest operating system heartbeat monitoring.

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?

• AA. 15 minutes
• BB. 60 minutes
• CC. 105 minutes
• DD. 90 minutes

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?

• AA. The virtual infrastructure environment must connect application virtual machines and management services to new physical network switches
• BB. The virtual infrastructure environment must connect application virtual machines and management services to separate distributed virtual switches (DVS)
• CC. The virtual infrastructure environment must connect application virtual machines and management services to separate VLANs
• DD. The virtual infrastructure environment must connect management services to a vSphere standard switch (VSS)

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.)

Select 2 answers.

• AA. The backup service will store data in a secure facility
• BB. The backup service has sufficient capacity for the new requirements
• CC. The customer will update their hardware standard to support rack mount servers
• DD. All virtual machines will be deployed with the same resource profile for production and development
• EE. The clusters will have a minimum redundancy of N+1
