Introduction
The Server+ certification program was developed by CompTIA to provide an industry-wide
means of certifying the competency of computer server technicians. The Server+ certification,
which is granted to those who have attained the level of knowledge and troubleshooting
skills that are needed to provide capable support to the most commonly used server and
storage systems, is similar to other certifications in the computer industry. The theory behind
these certifications is that if you needed to have service performed on any of their products,
you would sooner call a technician who has been certified in one of the appropriate pro-
grams than you would just call the first so-called “expert” listed online.
CompTIA’s Server+ exam objectives are periodically updated to keep the certification
applicable to the most recent hardware and software. This is necessary because a technician
must be able to work on the latest equipment. The most recent revisions to the objectives—
and to the whole program—were introduced in 2021 and are reflected in this book.
This book is a tool to help you prepare for this certification—and for the new areas of
focus of a modern server technician’s job.
What Is Server+ Certification?
The Server+ certification program was created to offer a wide-ranging certification in the
sense that it’s intended to certify competence with servers from many different makers
and vendors. Everyone must take and pass one exam: SK0-005.
The Server+ certification isn’t awarded until you’ve passed the test. For the latest pric-
ing on the exams and updates to the registration procedures, call Pearson VUE at (877)
551-7587. You can also go to the website, www.vue.com, for additional information or to
register online. If you have further questions about the scope of the exams or related Comp-
TIA programs, refer to the CompTIA website at www.comptia.org.
Who Should Buy This Book?
If you want to acquire a solid foundation in servers and the storage systems they use, and
your goal is to prepare for the exams by filling in any gaps in your knowledge, this book is
for you. You’ll find clear explanations of the concepts you need to grasp and plenty of help
to achieve the high level of professional competency you need in order to succeed in your
chosen field.
If you want to become certified as a Server+ holder, this book is definitely what you need.
However, if you just want to attempt to pass the exam without really understanding the
basics of personal computers, this guide isn’t for you. It’s written for people who want to
acquire skills and knowledge of servers and storage systems.

xxvi Introduction
Performance-Based Questions
CompTIA includes performance-based questions on the Server+ exams. These are not the
traditional multiple-choice questions with which you’re probably familiar. These questions
require the candidate to know how to perform a specific task or series of tasks. The candidate
will be presented with a scenario and will be asked to complete a task. They will be taken to a
simulated environment where they will have to perform a series of steps and will be graded
on how well they complete the task.
Tips for Taking the Server+ Exam
Here are some general tips for taking your exams successfully:
■ Bring two forms of ID with you. One must be a photo ID, such as a driver’s license. The
other can be a major credit card or a passport. Both forms must include a signature.
■ Arrive early at the exam center so you can relax and review your study materials, partic-
ularly tables and lists of exam-related information.
■ Read the questions carefully. Don’t be tempted to jump to an early conclusion. Make
sure you know exactly what the question is asking.
■ Don’t leave any unanswered questions. Unanswered questions are scored against you.
■ There will be questions with multiple correct responses. When there is more than one
correct answer, a message at the bottom of the screen will prompt you to either “Choose
two” or “Choose all that apply.” Be sure to read the messages displayed to know how
many correct answers you must choose.
■ When answering multiple-choice questions you’re not sure about, use a process of elim-
ination to get rid of the obviously incorrect answers first. Doing so will improve your
odds if you need to make an educated guess.
■ On form-based tests (nonadaptive), because the hard questions will eat up the most
time, save them for last. You can move forward and backward through the exam.
■ For the latest pricing on the exams and updates to the registration procedures, visit
CompTIA’s website at www.comptia.org.
The CompTIA Server+ Exam Objectives
CompTIA goes to great lengths to ensure that its certification programs accurately reflect the
IT industry’s best practices. The company does this by establishing Cornerstone Committees
for each of its exam programs. Each committee consists of a small group of IT professionals,
training providers, and publishers who are responsible for establishing the exam’s baseline
competency level and who determine the appropriate target audience level.

Introduction xxvii
Once these factors are determined, CompTIA shares this information with a group of
hand-selected subject matter experts (SMEs). These folks are the true brainpower behind the
certification program. They review the committee’s findings, refine them, and shape them
into the objectives you see before you. CompTIA calls this process a job task analysis (JTA).
Finally, CompTIA conducts a survey to ensure that the objectives and weightings truly
reflect the job requirements. Only then can the SMEs go to work writing the hundreds of
questions needed for the exam. And, in many cases, they have to go back to the drawing
board for further refinements before the exam is ready to go live in its final state. So, rest
assured, the content you’re about to learn will serve you long after you take the exam.
Exam objectives are subject to change at any time without prior notice and at CompTIA’s
sole discretion. Please visit the certification page of CompTIA’s website at www.comptia.
org for the most current listing of exam objectives.
CompTIA also publishes relative weightings for each of the exam’s objectives. The
following tables list the objective domains and the extent to which they’re represented
on each exam.
SK0-005 Exam Domains % of Exam
1.0 Server Hardware Installation and
Management
18%
2.0 Server Administration 30%
3.0 Security and Disaster Recovery 24%
4.0 Troubleshooting 28%
Total 100%
The following sections look at the objectives beneath each of these domains in
more detail.
