9. You are in the process of building a lab environment to test a new network application.You would like to isolate the test environment from your production equipment as muchas possible to prevent any test changes from affecting your users’ daily tasks.What can youdo to protect your production environment from changes performed in your test lab?(Select all that apply.)A. Place a router or firewall between the network infrastructures connecting the test labto your production machines.B. Keep the network cabling for the test lab physically separated from the network hard-ware that provides connectivity to your production environment.C. Contain the test lab in a separate OU.D. Use 100MB Ethernet for your production machines, but only 10MB Ethernet for thetest lab.A,B.To prevent unauthorized network traffic from traversing between test environ-ment and production equipment, you can place a router or firewall between the twolocations to control network traffic between the two.You can also completely segregatethe two environments by using two completely disconnected cabling systems.C,D. Answer C is incorrect because separating the test lab into an OU in an existingdomain will not do much, if anything, to protect the production environment fromchanges made to the test lab. Answer D is incorrect because using two different speedsof Ethernet cabling will not prevent traffic from passing between the two environments.
