NT1330-Unit 2 Exercise 1
DNS Scenario

Dear junior IT,
Thank you for contacting me regarding your questions, and trust that I will do my best to help you. From what I understand, you work at two branch offices, and have been given the responsibility of discovering where to place an Active-Directory Integrated DNS server. You also have some question of what type DNS server would best meet your company’s needs. First let’s begin with the smaller branch supporting perhaps five user/workstations, with an unusually slow network. The question with such a small branch isn’t really about what kind of DNS server you need, but do you need a DNS server at all. If there is a very high level of file/data sharing, then yes perhaps you could benefit from a server, but configured in a secondary zone, such as an ADI. However, if there is not enough file/data sharing to really warrant the presence of the server, an ADI server could potentially slow down an already sluggish system.

Now let’s move on to the second, much larger branch supporting around thirty users. You stated that this branch has a much better network connectivity than its smaller counterpart. In this case, I would recommend a DNS server set up in the primary zone. The primary zone is the primary source of information within this zone. I would also further suggest moving your servers from the smaller branch to your larger branch. All files from the smaller branch could be accessed via a “VPN” remote link. This would allow the smaller branch the ability to use a much smaller router, which might help with the lag the users have experienced.

Warmest Regards,

Nt1330 Unit 2. Exercise 1. Dns Scenario

...Aaron Battaglia NT1330 UNIT 2. EXERCISE 1. DNS SCENARIO It is not required to put a DNS server in such a small location for only five users and snail like network connectivity doesn’t justify the amount of money it would cost to install a server(s) in that area. One exception would be if there is a great amount of file sharing, or other information that would need to be accessed daily by other spots on the network. This sometimes but rarely happens but we could have a situation where we put it in the in the server but we set it up as a secondary or Active Directory Integrated zone type. I recommend installing the servers in the location where you have 30 users and fast internet connection. You could do this also, try storing all the files from either location in the bigger office, and in the smaller location you could remote connect through Virtual Private Network. When we do this all the information from the smaller sight is stored off site. The sight with five users can be run with a cheap router and the server that has thirty users at the office will be set up as the primary zone; since this is utilizing the fast internet connection and has more users this is our MAIN BASE which you can call home. =) If you were to run Domain Name System on domain controllers there are Active Directory Integrated zones and Active Directory Integrated zones. In classical Domain Name Systems the zone data is stored in text files which sit on the Hard Drive; which of course is protected...

...some of theese roles on to more servers. It is also important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server. Recommended Best Practice setup of FSMO roles. Domain Controller #1 Place the two forest roles on this server. * Schema Master * Domain Master Domain Controller #2 Place the domain roles on this server. * RID Master * Infrastructure Master * PDC Emulator If more domains exist in the forest, place the domain roles on a server in theese domains like Domain Controller #2 Global Catalog configuration.

...NT1330 Unit 7. Exercise 1. AD OU Planning Scenario Review the following scenario: As an IT Administrator, you have been tasked with designing an Active Directory Domain Organizational Unit Structure for a new AD implementation at an existing organization. You are scheduled to meet with the management team and need to formulate a list of questions you will need answered in order to recommend an OU Structure appropriate to the organization. Develop a list of 5-10 questions to guide your design plan. 1.) How is the existing structure of the organization? 2.) How many departments will there be? 3.) How many sub-departments will be needed? These questions will help in documenting the existing structure of the organization so as to divide the administrative tasks into categories and document the administrators who are responsible for each category. Also, these will define the hierarchy of authority in the directory as well as what departments the company will have. 4.) What are the company’s physical/geographical sites? This will address the issue of different geographical divisions which will probably have different computer management needs. The design will be based on management of resources, users and geographical boundaries. This will make the administration easier. 5.) How many OUs will be needed within each Parent OU? 6.) Will departments need to share resources? 7.) What resources are required by each department? 8.) What group policies to be implemented and who’s...

Client Server Networking 2

...NT1330 M1 March 18, 2014 Unit 1 Exercise 1 TASK You are setting up a new network for your company. You have a single location with approximately 145 hosts. Plans IT plans should accommodate 50% growth within the next 2 years. Growth 70 – 75 more hosts. What subnet range/s should be used? I would use a Classless addressing and start with a Network address with a Subnet Mask of This gives you 254 hosts per subnet which accommodates for your 50% growth over the next 2 years. For the time being you could use this one subnet and add another down the road if needed. If we add a second subnet down the road, and we are using DHCP, we would also setup a DHCP Relay Agent to relay the DHCP Broadcast messages across both subnets. Should IP addresses be dynamically or statically assigned? While you are setting this up, you can statically assign IP addresses for your servers, routers, firewalls, and printers. The rest of the computers and laptops should be setup to use dynamic IP addresses from DHCP. It should be standard security to have a firewall installed for your network to protect company information. You would have a router setup at access the internet for business purposes. If DHCP is used, should a router, firewall, or Windows Server be utilized and why? I would definitely setup a DHCP server to centrally manage your IP address pool. DHCP gives you a centralized administration point for dynamic IP...

IP defines packet structures that encapsulate the data to be delivered and defines the addressing used to identify the source and destination information.
