12. Secure the test lab using physical measures, such as a card-reader onthe entrance door, and technical measures, such as a dual-homedrouter to segregate network traffic originating in the test lab fromtraffic passing on the production network.

Implementing the Test Network

After you’ve finished designing your test lab, you can finally get down to the actual businessof testing.The steps needed to create test procedures can be broken down into two concep-tual halves:Whatdo we want to test and howshould the tests be performed? You’ll oftenhear the former referred to as a feature test description, which lists all features or aspects of atechnology that need to be tested. For example, the feature test description when assessinghow trust relationships behave during an operating system upgrade might read somethinglike this:“All trust relationships between the Windows NT 4.0 domain PRODUCTION andthe Windows NT 4.0 domain SALES should continue to function normally when theSALES domain is upgraded to Windows Server 2003.”You should design tests that will measure the functionality of each feature included inyour design plan. Additionally, you need to test how your new network will function inconjunction with any existing systems in the production environment. For Windows sys-tems, you need to test hardware, driver, and application compatibility on every hardwareconfiguration that will be running a Windows operating system.

IPBe sure to test functionality with existing technologies even if they are going to beupgraded or replaced as part of the new installation. Although the new technologymay need to coexist with the old technology for only a short period of time, youneed to know in advance how the interoperability will behave.Another key factor in using a test lab is creating a schedule of when testing should beperformed. Especially if you have many different individuals or teams performing varioustests, this scheduling should be formalized, rather than handled on an ad hoc basis. Ideally,you should designate someone to act as a lab manager to maintain and upgrade the labhttps://traloihay.net
