Description Takes a path and returns a new path with the file name s extension changed. (Note that only the path string changes, not the actual file name extension.) Combines two compatible path strings. Returns the name of the directory in the specified path. Returns the name of the file extension in the specified path. Returns the name of the file in the specified path. Returns the file name without the extension in the specified path. Returns a full path to the specified path. This method can be used to resolve relative paths. Returns the root directory name in the specified path. Generates a random file name. Generates a temporary file in the file system and returns the full path to the file. Returns the path to the temporary file directory for the current user or system. Indicates whether a specified path s file name has an extension. Indicates whether the specified path includes a root directory.

confirm that this breaking point exceeds 15 times the peak load This will ensure that the application has some room to scale if new demands are placed on it 3 The transactional unit tests verify the user business functions From this perspective, you might prefer to create a single test and add to it and modify it as needed This gives you one test to verify that the entire set of business transactions work or don t work However, these tests will most likely also be used for defining the load, stress, and performance tests For these tests it is important to simulate actual user load based on actual user behavior In the case scenario the sales reps and reviewers work at different levels You should therefore create separate transactional unit tests per test case or user activity.

Because the ISA Server computer is now an SSL client, the Web server responds with a server-side certificate 4 After the SSL connection has been created, the Web server responds by sending the requested object back to ISA Server 5 ISA Server receives the object and decrypts it At this point, ISA Server inspects the information based on the firewall access rules and the HTTP policy If the reply is acceptable, ISA Server then encrypts the object again and passes it to the requesting client One of the important benefits of using SSL bridging is that it allows stateful inspection of SSL connections and application-layer filtering of the contents of HTTPS packets Because ISA Server decrypts each packet, it can inspect the application-layer data before re-encrypting the packet This prevents attackers from hiding malicious code inside SSL packets.

globally unique identifier (GUID) A 128-bit number, guaranteed to be unique, that is assigned to an object created in Active Directory. logical structure The administrative structure of Active Directory that includes domains, trees, organizational units, and objects. namespace object Any bounded area in which a name can be resolved.

This will allow you to distribute these tests across the simulated user load 4 First, you should suggest that the load test include network distribution as defined by the application support team (90 percent LAN, 10 percent VPN) Next, you ensure that the test team documents an actual user load pattern for the load tests They need to segment the tests based on how users work Last, it is important to define the number of concurrent users (see question 2) and what is meant by concurrent users For the load tests concurrent users should be defined as the number of users working with the application These users are working; they are not all executing simultaneous transactions Therefore, you should use standard (or real) think times between transactions 5 The testers need to set performance thresholds that should not be exceeded in order to verify that the load tests succeeded.

The most significant disadvantage with using SSL bridging is that encrypting and decrypting network traffic is CPU-intensive, so the ISA Server computer performance may be affected..

1. Correct Answers: A and D A. Correct: You need to add a reference to the System.Web.Services namespace. B. Incorrect: There is no namespace named System.Web.Services2. C. Incorrect: There is no namespace named System.Web.Services3. D. Correct: You need to add a reference to the Microsoft.Web.Services3 namespace. 2. Correct Answer: C A. Incorrect: This code would only be correct if you were configuring a router using WSE 2.0 and not version 3.0. B. Incorrect: This code not only references WSE 2.0, but it states that the file to be routed is literally named webservices. C. Correct: This code references the correct version of WSE and uses a wild card to specify all files with an .asmx file extension.
