CompTIA (Computing Technology Industry Association) is the Information Technology industry’s largest developer of vendor-neutral IT certification exams. This article will focus on one of its certification exams – the Network+ Certification. CompTIA’s original certification program launched in 1993 and since that time more than 1 million people have earned a CompTIA certification. The hardware based A+ certification was first launched in 1993. With respect to Network+, exam N10-001 launched back in 1999 and is now in its 4th release as N10-004. The CompTIA website lists nearly a quarter of a million holders of the Network+ certification.
I took and passed the N10-001 exam in August of 1999. The history of the exams are: N10-001 CompTIA Network+ Exam (1999 Edition) (Retired March 14, 2002) N10-002 CompTIA Network+ Exam (2002 Edition) (Retired June 30, 2005) N10-003 CompTIA Network+ Exam (2005 Edition) (Retired July 31, 2009) N10-004 CompTIA Network+ Exam (2009 Edition) (Slated for retirement in 2012) The Network+ Certification measures the skill set of the network technician in an effort to assess their comprehension of the theory and inner workings of network hardware installation, operation and troubleshooting. The exam is a stepping stone for network administrators that may wish to continuing to other networking certifications from Microsoft and / or Cisco certifications. With respect to the venerable Microsoft Certified Systems Administrator (MCSA) certification, Microsoft allows you to substitute some of the elective exams in this track for certain combinations of the A+/Network+ or Security+ certifications. If you look at the requirements for the you see that under the Elective exam: Choose one section at the bottom it indicates that you can substitute the elective exam for the following; Specific third-party (CompTIA) certifications: CompTIA A+ and CompTIA Network+ (both) or CompTIA Security+ (by itself).
According to the there are no actual prerequisites for candidates that wish to take the exam to get the certification. Having said that, Network+ candidates should have at least nine months of experience in network support and administration. In absence of that they should have formal academic training with some hands on practice and / on the job training. According to the most recent to the exam requirements ob the CompTIA website, the N10-004 exam has 100 questions in total that need to be completed in a 90 minute time period. A passing score is 720 on a scale of 100 to 900. If you become certified on Network+ before the end of 2010 you remain a holder of the certification for life. So as an example, my Network+ certification is still active despite my having taken the N10-001 exam eleven years ago.
In some employment situations as required it may be necessary for Network+ certified engineers to 're-test' to assess their skills on the technology released since they formally received the certification. This is changing going forward as of 1/1/11 and I have some additional details regarding these changes at the end of the article. If the network administrator is CompTIA Network+ certified under the 2005 objectives (N10-003) they are eligible to take the Network+ 2009 bridge exam (BR0-002) which is a 60-minute, 50-question test of the updated material between the two exams.
A passing score on BR0-002 is 500 on a scale of 100-900. If you are certified under N10-002 or N10-001 and need to re-certify for some reason you would need to take the complete N10-004 exam.
In the complete N10-004 exam there are six domains of knowledge and objectives to be learned completely in order to have the best chance to pass the exam and obtain the certification.
