VMware VMware Certifications 2V0-21.23 Questions & Answers

• Question 211:

  A vSphere cluster hosts a three-tier application. The cluster has 50% resources available. If a host in the cluster fails, the database server must be online before the application server, and the application server must be online before the Web server.

  Which feature can be used to meet these requirements?

  A. Predictive DRS

  B. vSphere HA Orchestrated Restart

  C. vSphere HA Restart Priority

  D. Proactive HA

  Correct Answer: B

• Question 212:

  What is the minimum network throughput in Gb/s for vSAN using the Express Storage Architecture (ESA)?

  A. 50

  B. 25

  C. 1

  D. 10

  Correct Answer: D

• Question 213:

  A VMkernel port is labelled PROD01 and uses the default TCP/IP stack. Currently, this VMkernel port is configured for supporting live virtual machine (VM) migrations. Which configuration change should the administrator make to isolate live VM migration traffic from other network traffic?

  A. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.

  B. Remove PROD01 and create a new VMkernel port with the TCP/IP stack set to provisioning.

  C. Create a new VMkernel port and set the TCP/IP stack to provisioning.

  D. Modify PROD01 by changing the TCP/IP stack to vSphere vMotion.

  Correct Answer: A

  Explanation: Select a TCP/IP stack from the list. Once you set a TCP/IP stack for the VMkernel adapter, you cannot change it later. If you select the vMotion or the Provisioning TCP/IP stack, you will be able to use only these stacks to handle vMotion or Provisioning traffic on the host. All VMkernel adapters for vMotion on the default TCP/IP stack are disabled for future vMotion sessions. If you set the Provisioning TCP/IP stack, VMkernel adapters on the default TCP/IP stack are disabled for operations that include Provisioning traffic, such as virtual machine cold migration, cloning, and snapshot migration.

• Question 214:

  An administrator is deploying a new all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA). What is the minimum supported network throughput in Gb/s for each host?

  A. 50

  B. 10

  C. 25

  D. 1

  Correct Answer: B

  Explanation: The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10. References: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan- planning.doc/GUID-FCEA0CDD-F40F-45EB-A27F-F24005BA0749.html

  vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6815-sub3

• Question 215:

  Which step is completed during Stage 1 of the vCenter Server Appliance deployment?

  A. Join a vCenter Single Sign-On domain

  B. Create a new vCenter Single Sign-On domain

  C. Select the deployment size

  D. Configure SSH access

  Correct Answer: C

  Explanation: The minimum network throughput in Gb/s for vSAN using the Express Storage Architecture (ESA) is 1 Gb/s, which is the minimum requirement for vSAN network adapters. However, VMware recommends using 10 Gb/s or higher for better performance and reliability.

• Question 216:

  An administrator creates a virtual machine that contains the latest company-approved software, tools and security updates. Company policy requires that only full clones are allowed for server workloads. A combination of which two tasks should the administrator complete to prepare for the deployment of this virtual machine for multiple users? (Choose two.)

  A. Set appropriate permissions on the virtual machine.

  B. Create a virtual machine customization specification.

  C. Upgrade the virtual hardware.

  D. Convert the virtual machine to a template.

  E. Take a snapshot of the virtual machine.

  Correct Answer: BD

  Explanation: Option B and D are correct because they allow the administrator to create a virtual machine customization specification, which can be used to customize guest operating system settings for multiple virtual machines, and convert the virtual machine to a template, which can be used to create full clones of server workloads. Option A is incorrect because assigning appropriate permissions on the virtual machine does not prepare it for deployment for multiple users. Option C is incorrect because upgrading the virtual hardware does not prepare it for deployment for multiple users. Option E is incorrect because taking a snapshot of the virtual machine does not prepare it for deployment for multiple users.
