VMware VMware Certifications 3V0-21.21 Questions & Answers

  • Question 11:

    An architect decides to separate virtual desktops and application servers into separate vSphere clusters to meet security and management requirements.

    What are two implications of this design decision? (Choose two.)

    A. There will be an increase in management overhead.

    B. Identical hardware must be procured for all hosts.

    E. There will be additional licensing and cost requirements for both clusters.

  • Question 12:

    An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC).

    During the discovery phase, the following information is documented:

    Cluster One Six ESXi hosts vSphere HA with host failures cluster tolerates = 1 Proactive HA is enabled and set to automated Fully Automated vSphere DRS Transparent Page Sharing (TPS) is enabled

    Cluster Two Eight ESXi hosts vSphere HA with host failures cluster tolerates = 1 Proactive HA is disabled Partially Automated vSphere DRS Transparent Page Sharing (TPS) is disabled

    Cluster Three Three ESXi hosts vSphere HA with admission control is disabled Proactive HA is not supported Transparent Page Sharing (TPS) is disabled

    Virtual Machine Resource Profile 1 Memory sharing techniques should not be used Virtual machines should be automatically restarted in the event of host failure if resources are available Automated initial virtual machine placement

    Virtual Machine Resource Profile 2 Memory sharing techniques can be used Virtual machines should be protected from any host hardware failures Automated initial virtual machine placement Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)

    A. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster One.

    B. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster One.

    C. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two.

    D. All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two.

    E. All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Three.

  • Question 13:

    Which of the listed requirements would be classified as a recoverability non-functional requirement?

    A. The platform must be integrated with existing change control policies.

    B. The platform must be able to support a maximum tolerable downtime (MTD) of 30 minutes.

    C. Maintenance windows must be scheduled to take place monthly during an established overnight period.

    D. The platform must be available 24 hours a day, 7 days a week with the exception of scheduled downtime.

  • Question 14:

    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. Stateless vSphere Auto Deploy

    B. Stateful vSphere Auto Deploy

    C. Scripted installation

    D. Interactive installation

  • Question 15:

    A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.

    Per the defined logical network configuration, there are two network adapters each used for:

    Management traffic vMotion traffic iSCSI traffic Virtual machine traffic

    Which design decision should the architect make to meet the customer requirement?

    A. Use Network I/O Control to define a reservation for vMotion traffic.

    B. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.

    C. Configure a dedicated TCP/IP stack for vMotion traffic.

    D. Combine vMotion and Management traffic to make use of four adapters.

  • Question 16:

    During a requirements gathering workshop, the customer provides the following requirement:

    A new vSphere platform must be designed securely and all interfaces must be protected against potential

    snooping.

    How should this non-functional security requirement be documented?

    A. Interfaces must be audited.

    B. Encrypted channels must be used for all communications.

    C. Unauthorized access to interfaces must be reported within 15 minutes.

    D. Communications must be through Private VLANs (PVLAN).

  • Question 17:

    An architect is designing a new backup solution for a vSphere platform that has been recently upgraded to vSphere 7.

    The architect wants the backup solution to perform the following:

    Full virtual machine image backup and restore Incremental virtual machine image backup and restore File level backup and restore within both Windows and Linux virtual machines LAN-free backup

    Which functional requirement should the architect include in the design of the new backup solution?

    A. The backup solution must leverage the VMware Consolidated Backup (VCB) framework.

    B. The backup solution must leverage virtual machine snapshots.

    C. The backup solution must leverage VMware vSphere Storage APIs - Data Protection.

    D. The backup solution must leverage VMware vStorage APIs for Data Protection (VADP).

  • Question 18:

    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?

    A. All business application virtual machines can be deployed into a single cluster within the primary data center.

    B. Each distribution hub should be configured with a backup device.

    C. The wide area network has sufficient bandwidth to support centralized management.

    D. Each cluster will have a minimum of four hosts.

  • Question 19:

    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?

    A. vCenter Server High Availability will be configured.

    B. The vCenter Server Appliance will be protected with vSphere Fault Tolerance.

    C. The cluster will be configured to use vSphere DRS in fully automated mode.

    D. The cluster will be configured with vSphere HA and set to restart virtual machines based on guest operating system heartbeat monitoring.

  • Question 20:

    As part of a requirements gathering workshop, the customer provides the following requirements for the

    design of a new greenfield virtual infrastructure:

    Some applications have a latency that must be less than 5 minutes.

    The solution must be able to support a workload growth rate of 10% per year.

    Which requirement classification is being gathered for the design documentation?

    A. Performance

    B. Manageability

    C. Recoverability

    D. Availability
