In the summer of 2017 NI changed the Certified LabVIEW Associate Developer [CLAD] exam to have a large focus on basic data acquisition measurements using DAQmx functions. NI no longer provides sample exams for the CLAD, but does provide a rather comprehensive set of exam preparation material which is reproduced below.
The sample questions that are provided on our site are for the older (prior to summer 2017) exam. There is certainly nothing wrong with studying these older questions but you will find a few of them to address topics that are no longer emphasized on the new exam format. In particular, questions about objects such as semaphores, occurrences, and rendezvous are not on the new exam.
In addition to the material from the NI courses LabVIEW Core 1, LabVIEW Core 2, and Data Acquisition Using NI DAQmx and LabVIEW, the following powerpoint presentations are excellent resources for preparing for the revised CLAD:
CLAD Exam Simulator Tool
There is a nice CLAD Exam Simulator program that has been developed by LabVIEW community member Carlos Rubalcava. This tool can be downloaded from the NI CLAD forum at the following link.
