COMPTIA A+ Practice Exam

Post error codes are a set of signals that a computer uses to indicate a hardware issue during the Power On Self Test (POST) process. Post error code 200-299 signifies a memory error, which means that there is an issue with the computer's RAM (Random Access Memory) modules. This could be due to faulty RAM sticks, incorrect configuration, or other hardware failures. Options A, B and D are incorrect because they do not correspond to this specific error code range and could indicate different hardware issues. For example, a CPU error would fall under the 400-499 error code range, and a video card error would fall under the 300-399 error code range. It is important to note that while these error codes provide a general indication of the issue, further troubleshooting and diagnostic tests would be required to determine the exact cause.
