CompTIA A+ 220-901 Exam Objectives
220-901 Domain 1.0 – Hardware – 34% of the exam
- The “PC Hardware” domain is now simply called “Hardware” in keeping with the certification’s new focus on all desktop devices. This is a common theme in the exam objectives, especially in the 220-902 exam objectives.
- This domain is almost identical to the 220-801 exam objectives, except for minor technology updates. For example, UEFI has been added and AGP has been removed.
- One significant change is the inclusion of printers into Domain 1.0. In the 220-801 exam objectives, printers was in their own domain. Don’t be fooled; there are actually more printer objectives in the 220-901 exam with the inclusion of virtual printers to the traditional laser, inkjet, thermal, and impact.
220-901 Domain 2.0 – Networking – 21% of the exam
- The focus of networking on the exam has changed a bit to emphasize networking from the perspective of the client computer. The exam objectives associated with TCP/IP still include topics such as IPv4 vs. IPv6 and the use of subnet masks, but the exam objectives associated with IP classes has been completely removed. The focus is now clearly on networking the computer instead of administering the network. You’ll have plenty of time for classes and sub-netting when you take your Network+ exam.
- Some less-popular technologies like Wi-MAX have been removed and newer technologies like 802.11ac have been added.
- The broad concept of network “topologies” such as mesh, ring, and bus, have been removed. Again, networking from the computing device perspective is emphasized.
220-901 Domain 3.0 – Mobile Devices – 17% of the exam
- This was formerly the “Laptops” domain, but it now includes laptops, tablets, and mobile phones. The “Mobile Devices” section from the 220-802 exam has effectively been moved into this 220-901 domain.
- The technology refresh is also part of this domain, with examples that include the removal of PCMCIA and the addition of USB adapters.
220-901 Domain 4.0 – Hardware and Network Troubleshooting – 28% of the exam
- This is where you’ll find the largest functional change to both the 220-901 and the 220-902 CompTIA A+ certification exams. This exam-specific troubleshooting domain effectively removes the large overlap from the 220-801 and 220-802 exam objectives. This modification will be a big help to those who want to focus on a single exam before moving to the next.
- The 220-801 exam did not include any command line commands in the exam objectives. With the addition of troubleshooting into the 220-901 exam, there are both hardware troubleshooting and networking commands to learn.
