QUESTION NO: 182

Which of the following does not apply to system-generated passwords?

A. Passwords are harder to remember for users.
B. If the password-generating algorithm gets to be known, the entire system is in jeopardy.
C. Passwords are more vulnerable to brute force and dictionary attacks.
D. Passwords are harder to guess for attackers.

Answer: C
Users tend to choose easier to remember passwords. System-generated passwords can provide stronger, harder to guess passwords. Since they are based on rules provided by the administrator, they can include combinations of uppercase/lowercase letters, numbers and special characters, making them less vulnerable to brute force and dictionary attacks. One danger is that they are also harder to remember for users, who will tend to write them down, making them more vulnerable to anyone having access to the user's desk. Another danger with system-generated passwords is that if the password-generating algorithm gets to be known, the entire system is in jeopardy.

QUESTION NO: 183
Which of the following is not a preventive login control?

QUESTION NO: 184
What is the most critical characteristic of a biometric identifying system?

A. Perceived intrusiveness

Answer: C
Accuracy is the most critical characteristic of a biometric identifying verification system.
Accuracy is measured in terms of false rejection rate (FRR, or type I errors) and false acceptance rate (FAR or type II errors).
The Crossover Error Rate (CER) is the point at which the FRR equals the FAR and has become the most important measure of biometric system accuracy.

QUESTION NO: 49

How does IBM Integration Bus allow for the debugging of Pattern Projects?

A. Create a run configuration in eclipse since there is no default support in the Pattern Editor.
B. The Pattern Project is deployed to the Integration Server similar to any application and debugged from the server.
C. The Debug Pattern support in the Pattern Editor builds and launches the pattern plugin in a new Toolkit instance and stops at any breakpoints in the Java code.
D. The eclipse Run Configuration support is incompatible with the Pattern Project. The only way to test the project is to generate the plugin and install it in a separate installation of the Toolkit in a different node.

Answer: B
Explanation:

Note: The Visual Flow Debugger is implemented as an extension to the Eclipse Java debugger, so this means that if you step into a Java Compute Node, and you have the source available in your workspace you can use all the facilities of the Java debugger including viewing the content of variables during message flow execution.

QUESTION NO: 50
Several applications in an organization use a common Java library, commom.jar. Two applications App1 and App2 have their own shared libraries shlib1.jar and shlib2.jar that reference common.jar. Which deployment method allows for the most reuse of the Java Library?

A. Deploy all the jar files as static libraries.
B. Deploy all the jar files as part of the applications.
C. common.jar deployed as a shared library along with the shlib1.jar and shlib2.jar as shared libraries.
D. shlib1.jar and shlib2.jar must now be deployed as static libraries and common.jar as a shared library.

Answer: D
Explanation:


Consider a scenario when you want to develop a set of common resources and make them available to multiple applications.

If you want to deploy and manage just one copy of those common resources, use a shared library. A shared library can be deployed directly to an integration server. Any application can reference the resources in that deployed shared library. If that shared library is updated, the changes are immediately visible to all referencing applications.

If you want each application to use a different version of the contained resource, use a static library. Each application that references that static library is deployed with its own private copy of that library. If a static library is updated, each application that references it must be repackaged and redeployed with the updated static library.
