Network+ Certification Readiness Review

Network+ Certification Readiness Review

Craig Zacker

296 pages, parution le 31/01/2002

Résumé

If you took the Network+ Certification exam today, would you pass? With the Readiness Review exam simulation on CD-ROM, you get a low-risk, low-cost way to find out! This next-generation test engine delivers randomly generated practice exams that cover the actual Network+ objectives. You can test and retest with different question sets each time-and with automated scoring, you get immediate Pass/Fail feedback. More important, you get answers to these four critical questions:
  • What do Network+ exam questions look like?
  • In what topic and skill areas am I proficient/deficient?
  • How should I focus my studies?
  • Am I ready for the real exam?

Use this Readiness Review to evaluate your proficiency with the skills and knowledge tested on the Network+ exam, including:

  • Media and topologies
  • Protocols and standards
  • Network implementation
  • Network support

After completing your practice sessions, use the companion book to review helpful explanations for all responses-right and wrong-and to identify areas for further study. Sharpen your test-taking skills, save valuable time and money, and build your confidence for the real exam with Readiness Review. It's the smart way to prep!
