Annex B DSAC 13 ELO's

The creation of a virtual version of something, such as an operating system (OS), a server, storage devices is ________

___ provides the centralized management plane of the VMware vSphere solution & allows creating clusters of VMware ESXi

Virtualization is the creation of a virtual version of something such as an operating system, server, or storage device.

A virtual machine, or VM, is an OS that is installed on a hypervisor and borrowsresources from the host server

Characteristics of hypervisors include:

___ provision or migrate any virtual machine to any physical server.

____ is required to unlock most of the enterprise features needed for production environments.

Software called hypervisions seperate the physical resources from the ________

A suite of tools that enhances the performance of the VM and improves management of the VM is:

The ____ represents the system component that interacts with the virtualization layer rather than with the host.

___ provides fault and security isolation at the hardware level and preserves performance with advanced resource control

Apple's Proprietary Control called Apple Filling Protocol

__ can operate as a standalone host, or it can be configured as part of a cluster of ESXi hosts called a vSphere cluster

The benefits of virtualization include greater efficiency and economies of scale.

___ is a process of partitioning the resources of a single server into multiple virtual servers.

vSphere Distributed (vDS) is a more powerful virtual networking construct than vSphere Standard Switch (VSS).

______ is the component of a computer system that performs the tasks required for computer applications to run.

____ take your physical resources and divide them up so that virtual environments can use them.

With _____ a large amount of storage space is provided in advance in anticipation of future storage needs.

___ is abstracting the application layer away from the OS allowing the application can run in an encapsulated form.

Ethernet network, lower costs, lower performance, good for small companies, and bandwidth of 1,2,4,8,10 Gbps describe:

Fiber network, high cost, high performances, and uses bandwidth 1,2,4,8,10,16 Gbps describe which kind of SAN?

___ allows applications to access files or other resources at a remote server. Can communicate with any server program.

Virtual representation of physical storage resources in the data center. It is the storage location for vm files.

Fibre Channel (FC) and iSCSI are two types of:

___ are used for ensuring connections between virtual machines as well as connecting virtual and physical networks.

How many vSphere capabilities and features are there?

The ____ layer is responsible for recreating the same or different environment where the guest will operate.

A ___ is a software program - a logical switching fabric that emulates a switch as a layer-2 network device.

___ is when the host server can run virtual machines using a hypervisor (a software program).

__ saves the entire state of a virtual machine to file, moves & copies virtual machines as easily as moving/copying file

The _____ represents the original environment where the guest is supposed to be managed.

The ___ on virtual machines assist in connecting to a network, to enhance communications, or to replace an older adapter

The process of pooling physical storage of multiple network storage devices so it looks like a single storage device:

How many types of virtualizations are there?

___ aggregates all local capacity devices available on the hosts into a single datastore shared by all hosts in the vSAN

vSphere Virtual Mcahine File System (VMFS) is a special high-perfoemance file system format optimized for storing VM's.

A network file system used for providing shared access to files and printers between machines on the network.

____ gives applications a place to store and access data on a short-term basis.

How many types of data stores are there?

____ runs multiple operating systems on one physical machine and divides system resources between virtual machines.

What is the minimum number of host clusters that can run on a vSAN?

____ acts like a lightweight operating software system and runs directly on the host's hardware.

______ helps eliminate storage underutilization problems by allocating storage space in a flexible on-demand manner

What is the maximum number of host clusters that can run on a vSAN?

___ runs as a software layer on an operating system, like other computer programs.

In a virtualized environment, the three major components are:

What is the management component of VMware vSphere?

A storage device connected to a network that allows storage and retrieval of data from a centralized location.

Guest and virtual machine are the primary system that users interact and run computations in

___ allows remote hosts to mount file systems over a network & is good for UNIX server-to-server file sharing.

iSCSI is a transport layer protocol that can provide block-level access to storage devices through a TCP/IP network.
