F10: Identify the most common reasons for implementing virtualization within a Packet Switching Network (PSN)
Server consolidation and Efficiency Legacy Application Support Legacy Operating System Support Demonstrations Testing Education and Learning
- Frees network planners from planning 1:1 Active Directory servers, roles, and services.
- Fewer physical servers mean less power, HVAC support, and Marines to manage and maintain as well.
- Supports legacy application and operating systems.
- Can also be used for demonstrations and testing of new configurations and applications.
- Is also great for education, training, and learning applications.
F10: Define virtualization
The process of implementing multiple operating systems on the same set of physical hardware in order to better utilize the hardware. It allows the network planner to run multiple operating systems independently on one computer.
F10: State the purpose of a Hypervisor
It is a bare metal Operating System, meaning that it is installed onto a computer as the primary Operating System. It is much more efficient than hosted virtualization software because it does not waste any resources of the computer. All of the resources are applied to the VMs.
F10: Identify the virtualization software employed within United States Marine Corps Packet Switching Networks (PSNs)
The Marine Corps primarily uses the VMWare family of virtualization software. Currently the hosted software available for use is VMWare Player, Workstation, and Server. And the Hypervisor software is ESX and ESXi.
F10: Identify the characteristics of a virtual server
A virtual machine has no knowledge of other virtual machines on the same physical computer, no knowledge of the virtualization software - hypervisor or hosted. Virtual machines communicate with other computers both physical and virtual on the network using the OSI model. There is no difference between frames and packets destined for a virtual machine than a physical machine. In fact the only difference between a physical server and a virtual server is that your eyes can see the physical server in a rack in a communications closet or Techcon. Virtual Machines have the same components that physical computers do “ CPU, RAM, Hard Drives, Network Interface Cards, and DVD-ROM drives. Virtual Machines operate by using a portion of resources on the physical computer. The hypervisor or host virtualization software takes the actual physical resources of the physical computer and makes them available to the virtual machines. Virtual machines will use the CPU from the physical computer, virtual RAM is allocated from the total amount of physical RAM on the computer. The virtual machine’s hard drive can be composed of space on the physical machine’s hard drive, a filer, or other file storage system. Each virtual machine is then linked to the Network Interface Card (NIC) of the physical computer. Each virtual machine is then given a unique IP address and networked through the host computer’s actual NICs. Other physical resources of the host like CD / DVD-ROM drives are also mapped to each of the Virtual Machines for their use.
F10: Identify the benefits of the four (4) characteristics of a good network design in a virtual environment
Fault Tolerance and Redundancy - easily moved; backed-up
Scalability - new virtual servers easily created; you can put any VM on any physical device; less power strain
Quality of Service - clone via LAN only; fixed resources on physical computer
Security - minimizes physical security
F11: State the purpose of Video Teleconferencing (VTC) as it relates to the Commander’s ability to command and control forces
The purpose of video teleconferencing is to offer commanders an unclassified or classified close video network cable of voice, video, and data exchange to facilitate face to face communication, meetings, and planning sessions.
F11: State the purpose of the H.320 family of protocols as it relates to Circuit Switching Networks (CSNs)
VTCs conducted over the circuit switched network utilize the H.320 standard.
F11: State the purpose of the H.323 family of protocols as it relates to Packet Switching Networks (PSNs)
The H.323 standard is the VTC standard for VTCs conducted across the packet switched network.
F11: Identify the five basic components of a Video teleconferencing (VTC) Network
Video Terminal Gatekeeper Gateway Multipoint Conference Unit (MCU) Proxy
F11: Identify the minimum compression standard for a H.323 Video teleconferencing (VTC) Network
The absolute minimum VTC compression standard that you can plan for is 128 Kbps; 64 Kbps for the voice circuit and 64 Kbps for the video circuit. Compression any lower that 128 Kbps will make the VTC unusable.
F12: Define customer service
Process by which the needs of your customers are met through customer centric, solution oriented and proactive measures
F12: Define help desk
An aspect of Customer Service which provides the central interface between users and the technicians who support them.
F12: Identify the components of a customer service plan
User / Customer Education
Helpdesk Procedures
System / Unit Responsibilities
