Free CLA - Certified LabVIEW Architect Exam Questions and Answers
CLA - Certified LabVIEW Architect is one of the NI tests covered here. Two separate ladders sit under the NI name. LabVIEW runs CLAD to CLD to CLA, each a stated prerequisite for the next; TestStand runs CTD to CTA, and the two do not connect. The delivery is unusual and worth planning around: CLAD, the recertification papers and the TestStand exams go through Pearson VUE, but a first sitting of CLD or CLA is scheduled directly with NI rather than at a third-party test centre. All are proctored and closed-book, fees are non-refundable, and NI publishes no question count, time limit or pass mark for any of them.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.
