study Mode Creates an untimed test during which you can review the correct answers and the explanations after you answer each question. Custom Mode Gives you full control over the test options so that you can customize them as you like. In all modes, the test user interface is basically the same but with different options enabled or disabled depending on the mode. The main options are discussed in the previous section, Lesson Review Options.

Implementing, Managing, and Maintaining Routing and Remote Access (4.0)

When you design a system that gives your company access to the Internet, you might want to consider having more than one way to connect to the Internet, especially if your company relies on this connectivity to do business. However, just as a security professional would not spend $50,000 to protect a company s data that is worth $5,000, you should consider the cost of your redundant system as it relates to the value of downtime or the inability to connect to the Internet. For example, if a company must wait several hours while the Internet service provider (ISP) repairs a downed Domain Name System (DNS) server, would that downtime cre ate a hardship for the company that could affect its financial viability Could the com pany lose Internet connectivity and without losing money to the extent that it would cause a financial hardship Companies that do thousands of transactions per minute over the Internet, such as investment trading companies or retail companies that sell large quantities of goods, might warrant the creation of redundant systems. Such a company would not only require the network infrastructure be protected with redundant systems but might also require redundant power systems. Government agencies might require gas-powered generators that would kick in if the public power supply experienced a blackout or brownout. Before designing redundancy into your connectivity design, ask yourself the following questions:

Column Name Description Open File Accessed By Type # Locks The name of the open files on the computer. The logon name of the user who has the file open. The operating system running on the computer in which the user is logged on. The number of locks on the file. Programs can request the operating system to lock a file to gain exclusive access and prevent other programs from making changes to the file. The type of access that the user s application requested when it opened the file, such as Read or Write.

When you deploy RPC over HTTP, you must configure a computer running Windows Server 2003 as an RPC proxy server. The RPC proxy server accepts the RPC over HTTP or HTTPS connections and translates them into regular RPCs. In a scenario in which you have deployed Exchange Server front-end and back-end servers, the Exchange Server front-end servers should be configured as RPC proxy servers. The high-level steps to configure Exchange Server 2003 for RPC over HTTP are as follows: 1. Configure the Exchange front-end server as an RPC proxy server by adding the RPC over HTTP subcomponent to the Windows Networking Services component. If you have Exchange Server 2003 Service Pack 1 installed, then use Exchange System Manager to configure the server as an RPC front-end server. 2. Configure the Authentication Method in the RPC virtual directory in IIS to use Basic authentication. Also configure the virtual directory to require SSL connections. 3. Modify the registry on the RPC proxy server and global catalog server to use specified port numbers. To communicate with the domain controllers and computers running Exchange Server, the RPC proxy server specifies which ports to use for communicating with the domain controllers, global catalog servers, and all the computers running Exchange Server with which the RPC client must communicate.

Use the following questions to help determine whether you have learned enough to move on to the next lesson. If you have difficulty answering these questions, review the material in this lesson before beginning the next lesson. You can find answers to these questions in the Questions and Answers section at the end of this chapter. 1. The research department in your organization has unique network access requirements. All the computers used by the department users are on a separate subnet that must be isolated from the production environment. The users need unrestricted Internet access. What should you do to facilitate that

Transport rule conditions, shown in Figure 6-15, determine which messages the transport rule will apply to. Transport rules without any conditions are applied to all messages, unless those messages meet a configured exception. It is possible for a rule to have multiple conditions. When a transport rule has multiple conditions, each one of those conditions must be met before the rule will be applied. The following conditions can apply to a transport rule:
