Unit 2 Exercise 1 DNS Scenario
Dear Junior IT Admin,
Thank you for contacting me regarding your questions, and that you trust I will do my best to assist you with your issue. 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 (ADI) Domain Name System (DNS) server. You also have some questions on what type of DNS server would best meet your company’s needs. First let’s begin with the smaller branch supporting five users and or 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 if you actually need a DNS server at all. If there is a very high level of file and or data sharing, then yes perhaps you could benefit from a server, but configured in a secondary zone, such as an ADI there is not enough file and or 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 and or workstations. You stated that this branch has 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. I would also further suggest moving your servers from the smaller branch to the larger branch. All files from the smaller branch could be accessed via a Virtual Private Network (VPN) remote link. This would allow the smaller branch the ability to use a much smaller and less expensive router, which might help with the lag the users have experienced. If you have any further questions, issues, or concerns feel free to contact me at your earliest convenience. Regards,

IT Admin
