Choosing between two certifications

Should you take CompTIA A+ or Network+ first?

Take A+ first if you are entering IT with no prior experience, and Network+ first if you already work in support and want to move toward infrastructure. A+ is broader and shallower; Network+ is narrower and deeper.

Where they overlap

The shared ground

Both cover networking fundamentals, and the overlap is real: A+ carries a Networking domain plus network troubleshooting, while Network+ treats the same ground as its entire subject. Studying A+ first means a meaningful part of Network+ is already familiar rather than new.

  • A+ is the wider netA+ spans nine domains — hardware, operating systems, mobile devices, virtualisation, security, software and hardware troubleshooting, and operational procedures. It is designed to make you useful across a help desk rather than expert in one area.
  • Network+ goes deeper on one subjectNetwork+ concentrates on five domains covering network concepts, implementation, operations, security and troubleshooting. Where A+ asks whether you can identify a network problem, Network+ asks whether you can design, secure and diagnose the network itself.
  • A+ costs more sittingsA+ requires two exams, Core 1 and Core 2, each up to 90 questions in 90 minutes, with pass marks of 675 for Core 1 and 700 for Core 2. Network+ is a single 90-minute exam with a 720 pass mark. That difference matters for both budget and scheduling.
  • Employers read them differentlyA+ signals that you can be trusted with users and endpoints. Network+ signals that you can be trusted with infrastructure. Neither replaces the other, and many roles list A+ as a floor and Network+ as a step up.
Which order

Taking them in sequence

The common path is A+ then Network+ then Security+. Skipping A+ is reasonable if you already do hands-on support daily; skipping Network+ before Security+ is not, because Security+ assumes networking knowledge it does not teach.

Question 1 of 3 · A+ · Mobile devices and computer hardware

A laptop charges normally with its original USB-C adapter. On a compatible dock, data and video work, but the battery drains under load. The dock delivers less power than the laptop requires. Which change addresses the evidence with the least disruption?

Answer and explanation

Best answer: Use a supported dock or power arrangement with sufficient delivered wattage

The measured power shortfall explains discharge under load even though data and video work. Use a supported arrangement that meets the laptop power requirement.

Why the other choices fit less well

Battery replacement is premature when the measured charging input is insufficient. Stable video does not indicate a graphics-driver fault; reducing refresh rate without checking the required and delivered wattage does not establish a supported charging arrangement.

USB-IF: power delivery

Question 2 of 3 · Network+ · Network architecture and protocols

Small packets cross a VPN, but larger packets fail. A capture shows that fragmentation is blocked, while the physical links remain healthy. Which investigation best targets the size-dependent failure?

Answer and explanation

Best answer: Path MTU and tunnel overhead

Tunnel overhead reduces available packet size. Examine the path MTU and the handling of packets that exceed it before changing unrelated services.

Why the other choices fit less well

DNS caching, application timeout, and DHCP lease duration do not explain a verified packet-size boundary across the tunnel.

Question 3 of 3 · A+ · Operational procedures

A user asks you to reset a slow laptop. Their only copy of an important folder is on its internal drive. What should you do before starting a potentially destructive reset?

Answer and explanation

Best answer: Back up the required files and verify that the backup can be read

Preserve the required data and verify the backup before a destructive operation. Confirm the destination and that the files open; an unverified backup is an assumption.

Why the other choices fit less well

A reset can remove data before recovery is possible. A renamed folder remains on the same drive. Cloud sync must be checked rather than presumed to cover local files.
