About This Book

Each topical Exam Cram 2 chapter follows a regular structure, along with graphical cues about important or useful information. Here's the structure of a typical chapter:

• Opening Hotlists ” Each chapter begins with a list of terms and concepts that you must learn and understand before you can be fully conversant with the chapter's subject matter. The section "Techniques You'll Need to Master" is very closely related to the formal objectives provided by Sun for that topic. The hotlists are followed by an introductory section to set the stage for the rest of the chapter.

• Topical Coverage ” After the opening hotlists, each chapter covers a series of topics related to the chapter's subject title. Throughout this section, I will highlight topics or concepts that are likely to appear in the exam. A special Exam Alert layout is used, like this:

  

  This is what an Exam Alert looks like. Normally it stresses concepts, terms, software, or activities that are likely to relate to one or more certification test questions. Anything found in Exam Alert format is worthy of greater attention on your part.

  
  

  Even though the book is structured to the exam, these flagged items are often of particular importance.

• Notes and Tips ” Throughout each chapter additional information is provided that, although not directly related to the exam itself, is still useful and will aid your preparation. A sample note is shown here:

  

  A note contains some additional information that is separate from the main content, but is still useful.

  
  

  A tip might tell you another way of accomplishing something in a more efficient or time-saving manner. An example of a tip is shown here:

  

  You can also enter multiple commands on the same line by using the semicolon (;) character as a command separator ”for example, to flush the routing table and add a new default route that uses host ultra10 as the gateway, enter the following on a single line:

   # route flush; route add default ultra10 

  
  

• Practice Questions ” A section at the end of each chapter presents a series of mock questions and explanations of the answers.

• Further Reading ” Each chapter ends with a section titled "Need to Know More?" This section provides direct pointers to resources offering more detail on the subjects that have been covered in the chapter.
