The main objectives of this section include creation and management of VM snapshots, different methods to create and manage Virtual Machines (VM), management of storage and policies, migrations, creation of Distributed Resource Scheduler affinity and anti-affinity rules, management of different users and their roles, configuration and management of the different options to secure vSphere environment i.e. VM encryption, security, Trusted Platform modules, certificates etc., the configuration of host profiles, how to utilize Lifecycle Manager, and configuration of alarms.

• Next section covers Optimization, Performance-tuning, and Upgrade procedures. Different objectives of this section are identification, monitoring of resource pools, the configuration of Network & Storage I/O Control, maintaining VM snapshots and its performance impact and upgrading of different vSphere components.

• Architecture and Technologies section includes the identification of different components of vSphere implementation, topology, different storage access protocols, differentiation between Network and Storage I/O Control, concepts of ESXi cluster, identification of vSphere standard and distributed switch capabilities, concepts of Lifecycle Manager, basics of virtual storage area network vSAN, Trust Authority architecture and Software Guard Extensions.

• 3rd section of the Exam describes the Installation, Configuration and Setup process. It is further divided into various objectives which cover Single Sign-on deployment topology, the configuration of VSS advanced virtual networking options, how to set up identity sources, deployment and configuration of vCenter Server Appliance, content library, Server backup, Trust Authority, certificates, Lifecycle Manager and many more. The complete objectives of this section can be found in the Exam Preparation Guide available on the website of VMware.

• Products and Solutions section includes identification of vCloud Foundation use cases, migration options, and use cases of DR. It also tells us what is the role of vSphere in Software-defined Data-centers. One of the objectives also includes the integration of vSphere with VMware Skyline.

More details about the sections and their objectives can be found in the Exam Preparation Guide.
