Question 1

This plane is made up of physical and virtual devices such a switch is riders firewalls and load balancers they receive and send network messages on their way to their destinations this is a plane were bitch cross interfaces zoster blame her messages are decapsulated to examine layers or of headers, Mac addresses are matched to switch porch, addresses are changed for not processing and messages are read encapsulated for the jump to the next device

Answer 1

Infrastructure playing or data plane

Question 2

Think of this plane as the networks bring it handles the decision making process of traditionally the infrastructure plan in the control plane coexist on the same device with ST in the control plane is abstracted to an SDN controller with remotely imagine the networking devices

Answer 2

Control plane

Question 3

The STM controller also communicates with network applications using APIs. Applications to STN might need to communicate with include web browsers, voice over IP software, network services like DNS and app specific to SDN

Answer 3

Application clean

Question 4

While not a typical there for never communications plane should be considered part of the control plane it allows network administrator storm only managed network devices monitor those devices and I was data collected about those devices

Answer 4

Management plane

Question 5

Skin controller serve as – – – – between network applications and network hardware to ensure the networking best support the needs of those applications

Answer 5

Middleman

Question 6

– – – – – Design varies by manufacture what are partial variation is the degree in which the control clean a centralized to the SDN controller

Answer 6

SBN controller

Question 7

This is a storage networking architecture that runs separately from Internet net work to maximize speed of data storage in access

Answer 7

Fiber channel

Question 8

Fiber channel requires special hardware, which makes it an expensive storage connection technology. Specialized FC switches connect Sam storage devices with each other and with the – – – –

Answer 8

Outside Netwerk

Question 9

This is a newer technology that allows FC to travel over ethernet hardware and connections

Answer 9

Fiber channel over ethernet or FCOE

Question 10

This is a transport layer protocol called iSCSI transport layer that runs on top of TCP to allow faster transmissions Overland win and the Internet you can work on twisted pair ethernet networks with ordinary Ethernet nics

Answer 10

Internet SCSIs

Question 11

Like FC require specialized network hardware. Although it’s very fast Infini band tends to serve if you niche markets rather than a big widely available

Answer 11

Ib or Infini band

Question 12

This is a virtual or logical version of something rather than the actual physical version

Answer 12

Virtualization

Question 13

This creates and manages a VMs allocates hardware resources for the host and any of its yes VM

Answer 13

Hypervisor

Question 14

This hypervisor installs on the computer before any OS and is therefore erroneously called a bare metal hypervisor in reality does hypervisor is itself a minimal operating system many of which are built on Linux kernel

Answer 14

Type one hypervisor

Question 15

This installed in a host of us as an application I just called a hosted hypervisor.

Answer 15

Type two hypervisor

Question 16

Another hypervisor – – – – – – is native to Linux OS and also has elements of both a type one and type two hypervisor will install it effectively converts existing Linux OS to a type one hypervisor however the original OS is still accessible I still host other applications

Answer 16

KVM or kernel based virtual machine

Question 17

Every VM has its home virtual network adapter or – – – – – – that can connect the VM to a Netwerk and either virtual or physical. Just like a physical Nick eight – – – – – operates at the data link layer and provides computer with network access

Answer 17

V-NIC or virtual Nic
