Which of the following services allows a user to run specific programs and tools with diverse permissions than the user's current logon provides?
Correct Answer: B
Section: Understanding server maintenance Explanation: RunAs service allows a user to run specific programs and tools with diverse permissions than the user's current logon provides. Account with restrictive permissions should be used by administrators to perform routine, non-administrative tasks, and use an account with broader or full permissions only when performing specific administrative tasks. To run the tools (that require broader permissions) without logging off and back on, a user can log on with a regular user account and use the runas command. Incorrect Answers: A: A WCF Service is composed of three parts: a Service class that implements the service to be provided, a host environment to host the service, and one or more endpoints to which clients will connect. All communications with the WCF service happens via the endpoints. The endpoints specify a Contract that defines which methods of the Service class will be accessible via the endpoint; each endpoint may expose a different set of methods. The endpoints also define a binding that specifies how a client will communicate with the service and the address where the endpoint is hosted. In Windows Server, Windows Activation Services can be used to host the WCF service. Otherwise the WCF service can be hosted in IIS, or it can be self-hosted in any process by using the ServiceHost class, which is provided by WCF. A self- hosted WCF service might be provided by a console-based application, a Windows Forms application, or a Windows service. C: A Web service is a way of communicating between two electronic devices. The World Wide Web Consortium (W3C) defines a "Web service" "as a software system intended to support interoperable machine- to-machine interactions over a network. It has an interface deviced in a machine-processable format, particularly the Web Services Description Language (WSDL). Other systems interact with the Web service in such a way as is approved by its description; using SOAP messages and conveyed using HTTP with an XML serialization combining other Web-related standards." The W3C also identifies two major classes of Web services, which are as follows: 1. The REST-compliant Web services in which the basic use of the service is to manipulate XML representations of the Web resources through a uniform set of "stateless" operations. 2. The Arbitrary Web services in which the service may possibly represent an arbitrary set of operations. D: The WMI service runs side-by-side with WinRM and provides requested data or control through the WMI plug-in. A user can continue to obtain data from standard WMI classes, such as Win32_Process, as well as IPMI-supplied data.
Question 82
This question requires that you evaluate the underlined text to determine if it is correct. You need to troubleshoot network environment problems. First, you define the issues that are most likely causing the symptoms. Then you eliminate each issue until the symptoms disappear. This approach is referred to as "performance" troubleshooting. Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed" if the underlined text makes the statement correct.
Correct Answer: A
Explanation/Reference: Explanation: The ability to troubleshoot effectively reduces downtime and increases safety. A Systematic approach brings efficiencies to the process of troubleshooting. Preparation Step 1: Observe Behavior Step 2: Define Problem Area Step 3: Identify Possible causes Step 4: Determine Most Probable cause Step 5: Test and Repair Follow-up References: http://www.troubleshootingskills.com/how-it-works/systematic-approach/
Question 83
What program is usually used to connect to a computer remotely?
Correct Answer: A
Remote Desktop allows a user running the Remote Desktop program to access a server remotely. By default, Windows Server 2008 R2 supports two remote desktop connections-three if youalso count the console mode, which is the active connection as if you were actually sitting in front of the server keyboard and monitor.
