Described briefly, WMI sources of information ( providers ) output information about their components (devices, services, applications, and so on) to the WMI Object Manager, which enters the information into the WMI database ( repository ). Depending on what is accepted as input and returned as output by each provider, administrators will be able to use methods to manipulate the components, set properties, and configure events that can alert administrators to changes in the components. The WMI Repository can be accessed by management tools supplied by a system, application, or device vendor; through Application Programming Interfaces (APIs) or scripting tools (Windows Scripting Host, for example); or from the command line using Windows Management Interface Command-line (WMIC).

Answer B is correct because it allows the host computer to respond to ping requests. Answer A is incorrect because this option passes on information about connected routers and the flow of traffic from the computer. Answer C is incorrect because this option allows the computer to send a message to slow the flow of data. Answer D is incorrect because this option allows routers to redirect data to more favorable routes.

In 7, Group Policy Settings, you learned to configure auditing for several types of activities, including access to folders and changes to directory service objects. Windows Server 2008 also enables you to audit the logon activity of users in a domain. By auditing successful logons, you can look for instances in which an account is being used at unusual times or in unexpected locations, which might indicate that an intruder is logging on to the account. Auditing failed logons can reveal attempts by intruders to compromise an account. In this lesson, you will learn to configure logon auditing.

When you create an application domain and launch assemblies, you have complete control over the host evidence. Evidence is the information that the runtime gathers about an assembly to determine which code groups the assembly belongs to. The code groups, in turn, determine the assembly s privileges. Common forms of evidence include the folder or Web site the assembly is running from and digital signatures. By assigning evidence to an assembly, you can control the permissions that will be assigned to the assembly. To provide evidence for an assembly, first create a System.Security.Policy.Evidence object, and then pass it as a parameter to the application domain s overloaded ExecuteAssembly method. When you create an Evidence object with the constructor that requires two object arrays, you must provide one array that represents host evidence, and a second one that provides assembly evidence. Either of the arrays can be null, and unless you have specifically created an assembly evidence class, you will probably assign only the host evidence property. It might seem odd that Evidence takes generic object arrays instead of strongly typed Evidence objects. However, evidence can be anything: a string, an integer, or a custom class. So even if you are using the evidence types built into the .NET Framework, you will have to add them to an object array.
