31 important questions on VSphere Overview, Components, and Requirements - vSphere Components and Editions

What is vSphere HA?

A feature provides automated failover protection for VMs against host, hardware, network and guest OS issues. In the event of host system failure, it performs cold migrations and restarts failed VMs on surviving hosts.

What is distributed Resource Schedular (DRS)?

A feature that places and starts VMs on appropriate ESXi hosts and hot-migrates VMs using vMotion when there is contention for compute resources.

What is Storage vMotion?

A feature that performs live migrations with negligible disruption of VMs from a source datastore to a target datastore.

What is Fault Tolerance (FT)?

A feature that provides live migrations with negligible disruption of VMs from a source datastore to a target datastore.

What is Distributed Power Management (DPM)?

A feature that optimizes power consumption in an ESCi cluster.

What is Proactive HA?

A feature that minimizes VM downtime by proactively detecting hardware failures and placing the host in Quarantine Mode or Maintenance Mode.

What is Content library?

A centralized repository used manage and distribute templates, ISO files, scripts, vApps, and other files associated with VMs.

What is Host profiles?

A feature that provides a means to apply a standard configuration to a set of ESXi hosts.

What is vRealize Suite?

A suite of products that add operations (vRealize Operations Manager), automation (vRealize Automation), and orchestration (vRealize Orchestrator) to a vSphere environment.

What is the difference between vSphere 6.x and vSphere 7.0?

  • vSphere 6.x supports vCenter Server topologies and configurations such as vCenter Server Appliance, vCenter Server for Windows, embedded PSC, Enhanced Linked Mode, and Embedded Linked Mode.
  • vSphere 7.0 is much simpler

What vCenter Server configuration and topology does vSphere 7.0 have?

  • Windows-based vCenter servers not supported
  • PSC integrated into vCenter Server Appliance 7.0
  • Platform Services Controller Administration replaced with vSphere Authentication

What services does vCenter Server Appliance have?

  • vCenter Single Sign-On
  • Security Token Services (STS)
  • Administration server
  • vCenter Lookup Service
  • VMware Directory Service
  • vCenter Server plug-ins
  • vCenter Server database
  • tcServer
  • License Service
  • vCenter Server Agent
  • Host Agent

When you upgrade or migrate a vCenter Server deployment that uses an external PSC, what do you have to do?

Converge the PSC into a vCenter Server Appliance instance that you specify.

What do you do when upgrade or migrate using the CLI-based installer?

Specify replication using JSON templates.

What is Single Sign-On (SSO) Domian?

The local domain for authentication to vCenter Server and other VMware products.

What is Enhanced Linked Mode?

Used to link multiple vCenter Server systems and you can log in to all linked vCenter Server systems simultaneously and manage the inventories of the linked systems.

How to join vCenter Server system in Enhanced Linked Mode?

Connect to the same vCenter SSO domain.

What license is required for Enhanced Linked Mode?

vCenter Server Standard

What do you need for a vCenter HA cluster?

Three nodes:
  • vCenter Server Active Node (Management Network)
  • vCenter Server Passive Node (Management Network)
  • Witness (vCenter HA Network)

Mention the descriptions of the different vCenter HA nodes

  • Active
    • Is the active vCenter Server instance. Uses a public IP addres for  the management interface. Replicates data to the Passive node using the vCenter HA network. Communicates with the Witness node using the vCenter HA network.
  • Passive
    • Is cloned from the Active node. Uses the vCenter HA network to constantly receive updates from the Active node. Automatically takes over the role of the Active node if a failure occurs.
  • Witness
    • Is a lightweight clone of the Active node. Provides a quorum to protect against a split-brain situation.
