VMware VMware Certifications 3V0-21.21 Questions & Answers

• Question 21:

  An architect is designing a new vSphere cluster. The requirement is to provide a total of 96 CPU cores and

  1.5 TB RAM across all hosts.

  The following information has been provided:

  Two different physical hardware profiles are available for the ESXi hosts in the cluster.

  -

  Profile 1: 16 CPU cores and 256 GB RAM

  -

  Profile 2: 32 CPU cores and 512 GB RAM

  Profile 2 is twice as expensive to purchase as Profile 1.

  Which two aspects should the architect consider when selecting the hardware profile? (Choose two.)

  A. The manufacturer and model of the CPUs in the hosts

  B. The amount of capacity available for failover of virtual machines within the cluster

  C. The downtime allowed for virtual machines that will be running within the cluster

  D. The cost to procure and maintain the hardware

  E. The number of virtual machines that will be running within the cluster

  Correct Answer: BE

• Question 22:

  What is a benefit of using a scale-out method for handling vSphere cluster growth?

  A. An increase in the recovery time objective (RTO) for the cluster

  B. Faster to reach the limit of virtual machines per host

  C. An overall reduction in the license costs for the cluster

  D. Less potential impact to virtual machines during a single host failure

  Correct Answer: B

• Question 23:

  Refer to the exhibit.

  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?

  A. Enable vSphere HA and add a VM Override with VM Restart Priority set to Highest.

  B. Enable Fault Tolerance.

  C. Enable Sphere HA and maintain the default settings.

  D. Enable vSphere HA and add a VM Override with VM Restart Priority set to Lowest.

  Correct Answer: D

• Question 24:

  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?

  A. VMW_SATP_LOCAL

  B. VMW_PSP_MRU

  C. VMW_SATP_DEFAULT_AA

  D. VMW_PSP_FIXED

  Correct Answer: B

• Question 25:

  A architect is designing a new VMware software-designed data center (SDDC) using vSphere 7 to meet the following requirements:

  The SDDC must be deployed at two locations: primary and secondary. vSphere Replication must be used to replicate virtual machines between the two locations. Site Recovery Manager must be used to orchestrate disaster recovery (DR) activities. One single-sign on (SSO) domain must be used to authenticate access at both locations.

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

  A. A vCenter Server Appliance will be deployed to each site. Unique SSO domains will be created per site.

  B. A vCenter Server will be installed on Windows virtual machines deployed to both sites.

  C. A vCenter Server Appliance will be deployed to each site.

  D. A vCenter Server Appliance will be deployed to the primary site only.

  Correct Answer: D

• Question 26:

  The architect for a large enterprise is tasked with reviewing a proposed design created by a service partner.

  Which design elements are expected to be detailed within the physical design section of the documentation?

  A. A design diagram illustrating the configuration and specific attributes, such as IP addresses

  B. A list of requirements, constraints, and risks

  C. A solution architecture diagram with the components and data flow

  D. An entity relationship diagram describing upstream and downstream dependencies for specific service components

  Correct Answer: B

• Question 27:

  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.)

  A. Create a local content library in the primary vSphere environment and enable publishing.

  B. Create and publish a new subscription to a new subscriber library for each target vSphere environment.

  C. Deploy the OVF images to vSphere and clone as an OVF template to a local content library.

  D. Deploy the OVF images to vSphere and clone as a VM template to a local content library.

  E. Edit the Auto Sync Refresh Interval advanced setting for each subscribed library.

  F. Add a new subscriber library from each vSphere environment.

  Correct Answer: ACF

• Question 28:

  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?

  A. Enable vSphere HA and add a VM Override with VM Restart Priority set to Disabled

  B. Enable Fault Tolerance

  C. Achieve application availability with snapshots

  D. Enable vSphere HA and add a VM Override with VM Restart Priority set to Lowest

  Correct Answer: A

• Question 29:

  Which two statements are true about gathering functional business and application requirements? (Choose two.)

  B. It leverages a single set of questions for all stakeholders

  C. It might require multiple rounds of stakeholder interviews

  D. It builds stakeholder consensus

  E. It is a non-iterative process

  Correct Answer: AC

  A. Use Storage DRS.

  B. Use VMDK anti-affinity rules.

  C. Use multiple datastores for heartbeat.

  D. Use a minimum of three storage arrays.

  E. Use VM to host DRS rules.

  Correct Answer: AC
