An account executive on your company s outside sales team just returned from a major networking conference. His laptop was stolen from him while he was passing through airport security. You have a new replacement computer available. His data was backed up to a network server before he left for the conference, so it is possible to restore a recent copy of his data to the new computer. You are more concerned that the thief might have compromised proprietary and sensitive information. You want to safeguard your firm s confidential data against potential theft in the future. Which of the following steps do you take to protect the account executive s replacement computer when you install Windows XP Professional on it Choose two correct answers. A. You configure the computer so that the Welcome Screen is enabled. B. During the installation of Windows XP Professional, you specify the FAT32 file system for the single partition on the hard disk. C. You add the computer to the corporate domain and issue user certificates for Secure/Multipurpose Internet Mail Extensions (S/MIME) and EFS from the Active Directory integrated Certificate Services Certificate Authority. You install the certificates onto a smart card, and then instruct the user to keep the smart card in his wallet when not in use. D. Using EFS and the user s logon credentials, you encrypt the user s My Documents folders and other folders where the user stores data. You also enable S/MIME in email client software and teach the user how to use both features. E. You install the Recovery Console and configure it for automatic administrative logon.

has better defaults. However, JDK 5.0 annotations are sometimes more difficult to read than XDoclet annotations, because they aren t inside regular comment blocks; you should use an IDE that supports configurable syntax highlighting of annotations. Other than that, we found no serious disadvantage in working with annotations in our daily work in the past years, and we consider annotation-metadata support to be one of the most important features of JDK 5.0. We ll now introduce mapping annotations and use JDK 5.0. If you have to work with JDK 1.4 but like to use annotation-based metadata, consider XDoclet, which we ll show afterwards. Defining and using annotations Before you annotate the first persistent class, let s see how annotations are created. Naturally, you ll usually use predefined annotations. However, knowing how to extend the existing metadata format or how to write your own annotations is a useful skill. The following code example shows the definition of an Entity annotation:

Your current laptop computer is running Windows XP Professional, but you feel that its performance is unacceptable due to the speed of its central processing unit (CPU) and the amount of RAM installed. You acquire a new computer with significantly more RAM and a much faster CPU to replace your existing system. Which tool can you use to migrate your data and user settings from the old computer to the new one Choose the correct answer. A. Setup Wizard B. SysPrep C. File And Settings Transfer Wizard D. RIS

Installing Windows XP Professional (1.0)

The first line defines the package, as always. This annotation is in the package javax.persistence, the Java Persistence API as defined by EJB 3.0. It s one of the most important annotations of the specification you can apply it on a POJO to make it a persistent entity class. The next line is an annotation that adds metainformation to the @Entity annotation (metadata about metadata). It specifies that the @Entity annotation can only be put on type declarations; in other words, you can only mark up classes with the @Entity annotation, not fields or methods. The retention policy chosen for this annotation is RUNTIME; other options (for other use cases) include removal of the annotation metadata during compilation, or only inclusion in byte-code without possible runtime reflectivity. You want to preserve all entity meta-information even at runtime, so Hibernate can read it on startup through Java Reflection. What follows in the example is the actual declaration of the annotation, including its interface name and its attributes (just one in this case, name, with an empty string default). Let s use this annotation to make a POJO persistent class a Java Persistence entity:
