What changed in CompTIA A+ 220-1101 and 220-1102, new virtualization and cloud content, domain weight shifts, what older study materials miss, and how to...
The exact change
"The A+ operating systems domain is really a Windows administration exam with a macOS and Linux vocabulary test appended. Candidates who've used Windows professionally for a year already know 70% of this content. The other 30% is command-line tools and Active Directory concepts that aren't obvious from daily desktop use." - Professor Messer, CompTIA exam instructor --- "The biggest trap with A+ is using 1001/1002 study materials for the 1101/1102 exam. I've seen candidates fail specifically on cloud computing and virtualization questions because they weren't in their study guide. The exam objectives PDF is free from CompTIA, that's the authoritative list, not whatever study guide you happen to have." - Professor Messer, CompTIA training instructor
The A+ operating systems domain functions largely as a Windows administration exam with a macOS and Linux vocabulary test appended. Candidates who have used Windows professionally for a year tend to already know a large share of this content, with the remainder mostly command-line tools and Active Directory concepts that are not obvious from daily desktop use. --- The biggest trap with A+ is using 1001/1002 study materials for the 1101/1102 exam. Candidates can fail specifically on cloud computing and virtualization questions because they were not in an outdated study guide. The exam objectives PDF is free from CompTIA, and that is the authoritative list, not whatever study guide happens to be at hand.

Why this is better
De-attributed 2 separate unverified quotes attributed to Professor Messer in the same article to plain prose, removing an unverified-precision 70%/30% statistic in the process.
