CompTIA certifications

Read the eight as a doorstep and three rungs. Tech+ is the doorstep: one short exam, no experience assumed, and in its standard form the only credential here that never expires. A+ is the first rung and the only one that costs two sittings, 220-1201 and 220-1202, which have to come from the same version. Start at A+ if you have never worked a queue of tickets and want a support job, because that is the qualification those adverts name. Skip it if you already administer systems, or if you are aiming at networking or security: CompTIA recommends A+ before Network+ but does not require it, and a Security+ holder is rarely asked for it. Network+, Security+, Cloud+ and Linux+ make up the associate rung where most working people should enter, and CySA+ and PenTest+ the professional one, where the recommended experience (about four years of analyst work for CySA+, roughly three or four in offensive work for PenTest+) describes the difficulty rather than decorating it. Measured against the cloud providers' own tracks, CompTIA is better at the transferable layer: troubleshooting method, subnetting, reading logs, incident procedure, the things that survive a change of employer and need no relearning when a console is redesigned. Its exam versions also hold for roughly three years instead of chasing product releases, and A+ and Network+ can be sat in German, which Security+, Cloud+ and Linux+ cannot. It is weaker wherever depth on a live platform is the point: Cloud+ describes a managed database service in the abstract, while AZ-104 or the AWS associate exam make you run one.

Renewal is where a CompTIA collection is won or lost

Every certificate here except the standard Tech+ variant expires three years after it is issued. You keep it by logging continuing-education units and paying CompTIA's renewal fee, or by sitting the current version of the exam again. The unit requirement climbs with the tier: twenty for A+, thirty for Network+, fifty each for Security+, Cloud+ and Linux+, sixty for CySA+ and PenTest+. Added up naively, four certificates look like four separate maintenance projects every three years. They are not, because a higher CompTIA certificate renews the ones below it on the same chain. Passing Security+ renews Network+ and A+; passing CySA+ or PenTest+ renews Security+, and PenTest+ renews Network+ as well. One exam per cycle can therefore keep an entire support-to-security column current, which is why climbing the ladder costs less than it looks and why stopping at Security+ is the expensive choice. Two exams sit outside that chain. Linux+ is renewed by nothing above it, so its fifty units or a retake fall to you every cycle. Cloud+ carries the same fifty-unit demand with no documented upward renewal, so budget for it on its own terms. The rule of thumb follows from the mechanism: collect along one chain and maintenance is a single exam, collect sideways across specialisms and each credential bills you separately in units, fees and attention. That arithmetic, not the first sitting, decides whether a CompTIA collection is worth starting.
