How to Prepare For CWNA® - Certified Wireless Network Administrator

Preparation Guide for CWNA® - Certified Wireless Network Administrator

Introduction for CWNA® - Certified Wireless Network Administrator

The Certified Wireless Network Administrator (CWNA) gets guidelines and activities of 802.11 remote organizations. Obligations incorporate sending, overseeing, observing, and fundamental investigating of these organizations. The CWNA can depict gadgets and activities of current WLAN innovations. These are ensured in our CWNP CWNA-108 practice exams and CWNP CWNA-108 practice tests.

The CWNA test has no essentials; be that as it may, coming up next are suggested previously endeavoring the CWNA test:

  • Basic information on systems administration (switches, switches, cabling, and so on)
  • Basic information on TCP/IP
  • At least 1 year of work insight with remote LAN innovations

The abilities and information estimated by this assessment are gotten from a Job Task Analysis (JTA) including remote systems administration specialists (CWNEs) and experts. The aftereffects of this JTA were utilized in gauging the branches of knowledge and guaranteeing that the weighting is illustrative of the relative significance of the substance.

The CWNA certification is a foundational level wireless LAN certification for the CWNP Program. To earn a CWNA certification, you must take the CWNA exam at a Pearson Vue Testing Center and pass with a 70% or higher. Instructors must pass with a 80% or higher. However you choose to prepare for the CWNA exam, you should start with the exam objectives, which cover the full list of skills tested on the exam. The CWNA certification is valid for three (3) years. To recertify, pass one of the professional level certifications exams (CWSP,CWDP, CWAP) BEFORE your CWNA expires. By doing so, the CWNA will be renewed for another three (3) years. Or retake the current version of the CWNA exam.

At the point when you finish the CWNA test, you acquire credit towards the CWSP, CWDP, CWAP, and CWNE accreditations and you procure the CWNA certificate.
