Domains of Actual Evaluation

All in all, participants in this exam have to be well conversant with several topics that may be examined. However, note that the third and the sixth domains have objectives that are not evaluated so they won’t be detailed below. Thus, the topics of the 2V0-21.20 exam are the following:

• Architecture plus technologies;
• Products as well as solutions;
• Planning together with designing;
• Installation, configuration, as well as setup;
• Tuning of performance, optimization, along with enhancements;
• Troubleshooting in addition to repairing;
• Administrative including operational functions.

Looking at the first tested area, we can see that it involves pointing out the elements and the required conditions for the installation of a vSphere. It is also concerned with describing the topology of a vCenter Server, plus, the other subject areas include the identification as well as differentiation of protocols such as NFS for accessing storage according to vSphere, understanding how vSphere Network I/O Control & vSphere Storage I/O Control are different from each other, describing the architecture along with the uses of instant clone, providing a description of concepts for the ESXi cluster, and identifying the capabilities of a distributed and a standard vSphere switch. Still, on this subject, participants will be required to know the concepts of vSphere Lifecycle Manager, detail the fundamentals of vSAN as primary storage, recount the architecture of vSphere Trust Authority, and finally, provide an explanation of Software Guard Extensions.

In the second subject, candidates have to understand the function of vSphere in a software-defined data center. They also need knowledge in the identification of applications of vCloud Foundation as well as choices for migration. Furthermore, applicants should have an understanding of the use cases of DR, plus, the official 2V0-21.20 evaluation examines a potential taker’s expertise in the integration of VMware Skyline with vSphere.

Moving on to the fourth topic, describing execution topology for single sign-on is a required skill. Then, candidates will also be tested on the configuration of VSS virtual networking options. The other competencies that will be examined include the creation of identity sources, the implementation as well as the configuration of vCenter Server Appliance, the setup along with the configuration of VMware High Availability comprising advanced options, the installation & configuration of vCenter Server High Availability, the creation of the content library, and the configuration of file-defined backup for vCenter Server. After that, the candidates have to know how to analyze key log output for vSphere products. Next, the knowledge of the configuration of vSphere Trust Authority as well as vSphere certificates is also included in this domain. To cap it off, the other areas that are examined are the configuration of vSphere Lifecycle Manager and VMware Update Manager, booting of ESXi hosts in a secure manner, the configuration of various network stacks, configuring host profiles, and finally, the identification of boot choices.

The fifth item entails a number of subject areas. Thus, interested candidates will learn about the identification of resource pools applications here. They will also acquire skills for observing the vSphere space as well as the vCenter Server Appliance resources. Then, examinees should be able to point out and utilize the tools used in monitoring performance, set up Network I/O Control, accomplish the configuration of Storage I/O Control, understand how maintaining virtual machine snapshots affects performance, and make plans to upgrade a variety of vSphere components.

Lastly, in the seventh subject field, the creation and management of virtual machine snapshots is another skill that is examined. Besides, the real 2V0-21.20 evaluation may also check the use of various procedures to create virtual machines. Then, it may also include questions on the management of virtual machines and storage, the creation of Distributed Resource Scheduler affinity or non-affinity protocols for apps, the configuration & performance of various migration types, and the configuration of user management based on a role. The other knowledge and skills that may be evaluated in the final test are the configuration and management of options for securing vSphere environment, host profiles setup, and management, the utilization of baselines to perform updates as well as enhancements, the usage of vSphere Lifecycle Manager, and how to properly configure varied alarms.

Career Opportunities

Currently, cloud computing is experiencing fast-paced growth in the IT industry. This is because it leads to a reduction in the cost of IT for companies. The 2V0-21.20 exam’s related certificate, which is the VCP-DCV 2021, is relevant to this technology and is also well compensated financially.
