Q1. Design principles for group policy in shallow model
In the group policies, individuals find more compelling reasons to make the move to active directory by proper designing and implementation. There are various rules in the implementation of the policy such as the execution order, inheritance, and block inheritance. Execution orders are first processed followed by site GPO. The GPO setting is inherited from top level OU until the direct container. Block inheritance is applied to containers ensuring the correct application of downstream containers.
Design policy in a geographical model
The geographical model enhances the structure of the future urban areas and transportation networks, the simulation of the future displacement behavior and traffic evaluation on criteria of sustainability. The basic component of the simulation geographical model is a GIS design module in which the user constructs geographical design for future use.
Design principle for delegation in shallow model
Both computer policies and user policies can be defined in the same GPO. The User Configuration section of the GPO mostly defines the experience the user will have when logged in. These types of settings also exist in the Computer Configuration section, but this section also contains more settings related to the security of the computer, such as who can log on to the computer locally or how data is encrypted.
Design principle of object Administration in a shallow model
It shows the OU structure taking focus away from other areas of Active Directory design, such as planning the site topology or thinking about domain controller sizing. On the other hand, when OU planning is put on the back burner, Group Policy and delegation suffer.
One of the excuses happening occasionally is that the OU organization is flexible and can be changed later if it does not fit. It is true that the OU structure is flexible; however, administrators often discover that changing the OU structure down the road is harder than they had originally anticipated. Sure, new OUs can be added, but the old ones are not easy to clean up.
Design principle of object administration in a geographic model
The purpose of the geographical information systems is to function with the geographic information systems. It gives a formal definition providing the detailed functioning of the GIS other than other information system. The GIS has expanded lately and serve various functions within the society such as the urban planning, biological purposes, and natural hazard analysis.
Q2. Drawing of a network showing DNS zones and showing the equipments required to support the zones.
DNS means Domain Name System and a protocol providing the structure and framework of Web browsing. A conglomerate of root servers houses the internet protocols IPs addresses of the DNS servers having authority over individual domains. The DNS processes and interactions involve the communication between the DNS clients and the DNS servers during the resolution of DNS queries and the Dynamic update (Wilkerson & Van, 2015). DNS systems functions in unique ways.
When the DNS client needs to look up a name in a program the relevant queries resolve the issues through the DNS servers during name resolution and zone administration.DNS has various functions in the information technology discipline such as the specification of the domain name, resource code, and running of the windows operating systems. A DNS server can use its own cache of resource record information to answer a query.
The DNS server can also query or contact other DNS servers on behalf of the requesting client to fully resolve the name. There are various equipments required in the implementation of DNS systems such as the existence of a functional network system, with servers and the host stations. The transmission control protocols, User data protocols, Hypertext Transfer protocol, and the SIP protocols.

Show the difference between a forward look up and reverse look up zone?
In the basic functionality of the information technology both, the zones records are required to resolve the computer queries such as name for IP address and vice versa. The forward lookup zones resolve a device’s IP address for its name while the reverse lookups zones resolve a device name for its IP address. A forward lookup zone if supplied with a domain name returning the IP address for supplied domain. The reverse lookup zone is used to lookup the domain name when supplied with an IP address (Jøsang, 2015).
What circumstances will a reverse look up be useful?
There are various circumstances leading to the application of the reverse lookup such as the saving of time, getting focused and taking control.
Time saving
When dealing with online activities only the specific people are intended to be met not everybody on the net making it easier to perform activities such as online dating and others.
Getting focused
Many people meeting online are always interested in other people’s originality and locations making them focused and hone in persons meeting one another. The relationship of the of the correspondents depends on the age exact matches and locations of the individuals.
Taking control
The reverse lookup, help in the narrowing down the dating field and making more relevant meaningful connections with great and unbelievable pairing up of individuals.
Q3. Illustration of the IP v6 transition technologies
The transition technologies initiates by the installation and the configuration of the new protocol on all nodes within the network verifying that all the nodes and router operations work. The IP v6 can be established in a small or medium sized organization challenging of making a rapid protocol transition in large organizations. The access transition technologies are the mechanisms allowi...
