Option 1: Creating a Domain Model
Company Alpha has one location that contains the executive management team and all IT support, located in San Jose, CA, which contains one subnet. There are five other locations that are each organized using two subnets, each using static IPv4 addresses: Los Angeles, CA; Reno, NV; San Diego, CA; Seattle, WA; and Portland, OR. Describe the most likely domain model for the organization.
Note. The organization does not have an Internet presence but requires Internet access.
Write a 2- to 3-page paper that includes an internal domain name system (DNS) design for name-resolution.
· How will you decide whether to use both forward and reverse lookup zones?
· Why might you consider installing a redundant DNS infrastructure?
The San Jose office has an ISDN line that is part of a long-term lease. This line is occasionally used to send and receive potentially sensitive information.
· What type of server or server role is needed to handle this type of traffic?
Option 2: Creating a Domain Model (Graphical)
Company Beta has two main locations that contain IT support. Their Boston, MA location contains the executive management team, and the CIO is at this location. Their second main location is in Toronto, Canada. The Boston office supports three other locations (Concord, NH; Stratford, CT; and Philadelphia, PA), each of which has three subnets. The Toronto office supports two other Canadian locations (Vancouver and Montreal) each with two subnets.
Create a 1-page diagram (You may use Microsoft®Word's Shapes tool.) of the most likely domain model for the organization. The company has an Internet presence using the companybeta.com domain. Show a diagram of a domain name system (DNS) design for name-resolution.
Write a 1- to 2-page paper that explains the logic for your DNS design, supplements your diagram, and answers the following:
· The manager at the Toronto office wants to occasionally use an ISDN line to send sensitive information from a remote business location. How would you accommodate this requirement?
Option 3: Creating a Domain Model (Advanced)
Company Gamma Forwarders has three main locations that provide IT support. Their Dallas, TX location contains the executive management team and the CIO. Their other main locations are Mexico City, Mexico and Guadalajara, Mexico. The Dallas location supports two other locations (Austin, TX and Santa Fe, NM), each of which has two subnets. The Mexico City location supports two other Mexican locations (Ecatepec de Morelos and Nezahualcóyotl), each with four subnets. The Guadalajara location supports two other Mexican locations (Zapopan and Tlaquepaque), each with one subnet.
Create a 1-page graphical presentation and write a 2-page paper that shows the most likely domain model for the organization. The organization does have an Internet presence using the following domain: companygammaforwarders.com
Create a domain name system (DNS) design for name-resolution. Explain the logic for your DNS design.
The entire network has been upgraded to use IPv6. Given the long domain name, WINS single-label names have been in use on this network.
· What can you do to support users who want to continue using the short names that have become part of the corporate culture?
The Zapopan and Tlaquepaque locations require a process to send sensitive e-mail when their primary Internet service provider (ISP) is not functioning. They have an ISDN line for this purpose.
· How would you accommodate this requirement?
