Q

What is Desktop Virtualization?

A

A virtual desktop for end users to use

20
Q

What is Software-Defined Data Center?

A

In SDDC, all infrastructure is virtualized and the control of the data center is automated by software. `

21
Q

Explain SDDC (Software Defined Data Center) ?

A

SDDC is deployed with isolated computing, storage, networking and security resources that are faster than the traditional, hardware-based data center

All resources (CPU, memory, disk and network) of a software-defined data center are abstracted into files. The abstracted files bring the benefits of virtualization at all levels of infrastructure.

22
Q

What are Software Define Data Center Components?

A

Service Management and Automation

Cloud Management Layer

Virtual Infrastructure Layer

Physical Layer

Security Layer

23
Q

What is Service Management and Automation in SDDC

A

Use service management and automation to tract and analyze the operation of multiple data source in the multiregion SDDC.

Service Management deploys additional features like vRealize Operations/Automation/Orchestrator

24
Q

What is Cloud Management Layer in SDDC?

A

This layer in SDDC includes the service catalog, which houses the facilities to be deployed.

This layer in SDDC also includes orchestration, which provides the workflows to deploy catalog items.

This layer in SDDC also includes portal for end users to access and use the SDDC

25
Q

What is Virtual Infrastructure Layer in SDDC?

A

This layer in SDDC creates the virtualization platform for the hypervisor, pools of resources, and virtualization control.

26
Q

What is Physical Layer in SDDC?

A

The lowest layer of the solution. This includes compute, storage and network components

27
Q

What is Security Layer in SDDC?

A

Customers use this layer of the platform to meet demanding compliance requirements for virtualized workloads and to manage business risk.

28
Q

What is Cloud Computing and it’s Components?

A

Cloud computing makes use of the efficient pooling of an on-demand, self-managed, and virtual infrastructure.

Cloud Infrastructure
IT Automation
VDI
Hybrid Cloud

29
Q

What is Cloud Infrastructure in Cloud Computing?

A

Uses the high performance, availability and scalability of the SDDC to run mission-critical applications such as database, web applications and virtual desktop infrastructure (VDI)

30
Q

What is IT Automation in Cloud Computing?

A

Automate infrastructure and application delivery with self-service capabilities

31
Q

What is VDI in Cloud Computing?

A

Provides a complete solution for VDI deployment at scale.

32
Q

What is Hybrid Cloud in Cloud Computing?

A

Build a hybrid cloud with a common infrastructure. Connects your on-premises and off-premises data center that is compatible, stretched and distrubuted

33
Q

What is VMware Skyline?

A

Is a support technology that provides predictive analysis and proactive recommendations to help you avoid problems

34
Q

What are VMware Skyline Benefits/Features?

A

Issue Avoidance

Shortens the time it takes to resolved a problem so that you can get back to your business quickly.

35
Q

What is Skyline Health in Skyline Family?

A

A feature. This feature is available to all VMware customers.

Has vSphere and vSAN findings.

Supports vSphere 6.7 U1 and later

36
Q

What is Skyline Advisor in Skyline Family?

A

Available for Production and Premier Support Customers (and upgraded version)

Supports vSphere, vSan, NSX for vSphere, vRealize Operations Manager and VMware Horizon

Supports vSphere 5.5 and later

Automates log transfers and log Assist

Uses cloud based ID and access

37
Q

Difference Between Physical and Virtual Architecture?

A

Physical uses the components that are installed on the board.

Virtual uses components that are installed but are shared. They use the components through a thin layer called the virtualization layer or hypervisor.

38
Q

What is Physical Resource Sharing?

A

Multiple Virtual Machines running on a physical host, share the compute, memory, network and storage resources of the host.

39
Q

What is CPU virtualization?

A

In a physical environment, the operating system assumes the ownership of all the physical CPUs in the system. CPU virtualization emphasizes performance and runs directly on the available CPUs.

40
Q

What is Virtualized Host Memory Usage?

A

Creates a virtual address space for applications.

The allocated memory space is configured when the VM is created and has the same properties as the virtual address space.

41
Q

What is GPU Virtualization?

A

Virtualized Graphics.

Can be used for Virtual Desktops

Graphic Intensive applications

Can configure VMs up to four vGPU

42
Q

What is vSphere 7 Bitfusion?

Page: 36

A

Bitfusion provides elastic infrastructure for artificial intelligence and machine learning workloads

With Bitfusion, GPUs can be shared in a way that is similar to how vSphere shares CPUs

43
Q

What is VMware Host Client?

Page: 39

A

Is an HTML5-based user interface that you can use to manage individual ESXi hosts directly when vCenter Server is unavailable.

44
Q

What is vSphere Client?

A

The vSphere Client is an HTML5-Based client. You manage the vSphere environment with the vSphere Client by connecting to vCenter Server Appliance

45
Q

What is Power CLI?

A

A command-line and scripting tool that is built on Windows Powershell

  • Provides a powershell interface to vSphere API
46
Q

What is ESXCLI?

A

A tool that allows for remote management of ESXi hosts by using the ESXCLI command set

47
Q

What is ESXi?

A

ESXi is a hypervisor that you can buy with vSphere or get in a free, downloadable version.
