The CompTIA A+ Core 1 (220-1201) examination requires technicians to possess a deep understanding of mobile device hardware, particularly storage components. Objective 1.1 focuses on the practical tasks of monitoring drive health and executing appropriate replacement and upgrade techniques for mobile devices, which predominantly include laptops, convertible tablets, and ultrabooks.
Storage devices, primarily Solid State Drives (SSDs) and, less commonly today, Hard Disk Drives (HDDs), are critical components affecting system performance and data integrity. A technician must be proficient in identifying failing components, understanding various form factors, and safely performing physical replacements.
