Classification of Access Network Types - Assignment Example

? MegaCorp Surf Shoppe Information Techonology [Pick the Domain basically is a security boundary for a network located and made operational on the Local Area Network (LAN). It actually is a subnetwork made up of clients and servers, that actually are under the control of one central security database. Megacorp can instead of moderately and repeatedly authenticicating or validating to its individual servers and clients, stay within a domain . It lets the users have to just for once authenticate to a centralized server known as a domain controller (University of Exeter, 2012). Organizational unit is a part of active directory that is used for its organizing and management. Under Microsoft’s documentation,the term “organizational unit” is interchangeably used with the term “container”.It is a further subdivision of an active directory into which can be placed users, different systems (computers) and other organizational units that are operational in megacorp. These organizational units can be used for mirroring the organization’s structuring i.e., megacorp forest’s working and its operational maintenance. In fact, every domain can independently organize, implement and maintain its own organizational unit hierarchy. If megacorporation incorporates several domains, it can conveneiently create organizational unit structures in each domain that stands idependent and self operational against the structures in other domains. (Wei Wei, Bing wang & Chun Zhang, 2004) 2. If Megacorp services intend to connect and yet stay separate from the Megacorp forest structure, this can be done through offline domain join, which is progressively used in Windows Server 2007 and Windows Server 2008. It can be used to join a domain without actually engaging or contacting the domain controller. This way, megacorp Forest structure would connect and yet emain separate (karen Coyle & diane Hillman, 2007). Megacorp might intend to deploy many virtual machines in the data centre. Offline domain join would make it possible for the virtual machines to be joinesd to the domain name when they nitially start after the installation of windows 2008. This would additionally save a huge amount of time that could be required for wide scale virtual machine deployments. This scenario of domain join creates an aunthenticity relationship and a trust between the active directory domain and the system running the windows 2008 operating system. Windows 2008 server also offers a mechanism that can be used by negacorp services to connect and yet maintain their separate identity. Under this mechanism, domain join operations are performed undera read only domain controller (RODC). The following muktiple steps have to performed by read only domain controller (RODC) to process the domain join operation: 1. The computer account has to be created in advance in the directory and further settle certain attributes through the scripts. 2. Alongside, the Password Replication Policy (PRP) of the Read Only Domain Controller (RODC) has to be modified so as to permit the system that you want to join to be cached by RODC. 3. Duplication and replication of the system has to ensured so as to further facilitate the system through joining the domain. 4. Inform the computer that is about to join the domain through offline sources. 5. Finally, test through running a custom script that targets the Read Only Domain Control to facilitate the join. (University of Exeter, 2012) 3. Access networks are dramatically of different types as they consist of links between connecting the end user systems and the edge routers. The three most pervasive and widespread types are:Dial up, Assymetric Digital Subscriber Line (ADSL) and Hybrid Fiber Coaxical Cable (HFC). Ethernet and switched Ethernet are the commonly classified Local Area Network (LAN) technologies that can be incorporated by megacorp since most of the businesses use it. Mgacorp can additionally focus on the Wireless Local Area Network (WLAN) using the IEEE 802.11d standard that is most frequently being used in the offices. The various type of access networks have different type of functuniong oprerational setup based upon their capacity, the symmentry of horizontal, vertical and/or upward downward downloads and the physical media. Where dial up connections have a record of lesser time span, megacorp should experience with cable, modem and Assymetric Digital Subscriber Line as they provide a longer on line time. 1. IEEE 802.11d Mrgacorp can use this since it provides a physical layer for media access control (MAC) for WLAN. It coordinates the shared media through the use of multiple stations. If the media is busy, megacorp can still operate using a binary exponential backoff procuder. 2. DOCSIS If megacorp uses a cable network, it can avail the downstream channel from the Cable Modem Termination System (CMTS) to the headend to the cable at the main point shared by many different domains. (University of Exeter, 2012) 3. Ethernet, ADSL and Dial up They can be equally beneficial for megacorp since they have a dedicated access ang high bandwith. Another additionally advantage megacorp can have of using this access is that it has a high ability to detetct collisions. (Wei Wei, Bing wang & Chun Zhang, 2004) 4. The eqiupmwnts neede by surf shopping building to settle the minimum requirement list of display screen workstation system is as follows: Display screen keyboard Mouse WorkChair Desk Working Environment Display Screen: The screen must be placed at alomist a distance of 35 – 60 cm at all floors from the user’s eye sight. For touch typists, the screen should be elevated, with their eye levels conveneiently settled to be positioned abovethe eye glance level. Keyboard: The keyboards should have adjustable rear supports so as to raise the keyboard to a certain level. Mouse or Track ball: The mouse should be accessible with an easy reach and their should be sufficient space to move the mouse. Some mouse pads have a buiklt in wrist rest. All the users at different floors should be equipped with these pads Work Chair: The chair should be confortable in height and posture maintainence and have a five footed base with a castors and a swivel seat of comfort. It should have an adjustability to ensure horizontal handling of the keyboard. Desk: The work surface should have enough space for hurdle free writing. The tableis the actual work station and thus it shiuld be furnished well enough to equio the worker with all the facilities to focus on the target wriring/working. Environment: The working environment is in fact the biggest contributive factor. The lighting should be focused in brightness and quality based upon the floor it is used at. Ceiling light on the thir floor should not be too light to cause eye fatigue. Desk lamps should be arranged to overcome any light problems. The working space should be very conjusted that can create a problem for the mobility. Temperature, humidity and ventilation should also be focued since as a general rule, office environment temperature should not be lower than 16 degrees. The humidity level should be maintained at a suffice level on the third floor Fire Protection: There should be easy exit for third floor workers in case of any fire alarm and an easy to use fire extinguisher that can be used to kill the fuming before the fire breaks. There should also be equally suitable fire working for the workers on the first floor. 5. Since magacorp has rented its second floor to webheads, a different business entity has envaded their premises that could bring in a lot of additional environmental nuisance. Although the Webhead is on a different floor, the customer are employeemovements across the building can contribute towards creating lack of concentration amongst the employees. It also leads to lack of confidentiality of information. 6. Task: Preparation for active directory Installation: Procuder: Install the DNS Server Tool: Control panel Task: Install Active Directory Procuder: verify DNS registration and functioning, verify IP address maps, Install active directory,verify communication with other domain controllers, verify the operation of masters Tool: Dcpromo.exe, Dcdiag.exe and Netdiag. exe Task: Perform active directory post installation task Procuder: Determine whether a server object has child objects, verify the site assignment of a domain controller, move domain controller to a different site, check the status of the shared system volume. Tool: Active Directory Sites and Services 7. (visio.org, 2013) References karen Coyle & diane Hillman. (2007). D - Lib Magazine Organization.
