A+ netwrok+ Security+ challenging areas

precious
Yes three are many topics that are challenging for students to understand and some of the topics they are hard from A+ to Security for exam, DNS TXT records (SPF/DKIM/DMARC) and the we have subneting in CompTIA Network plus, Cryptography in Security plus.... I use analogies.

Imagine your email domain is a house, and the internet is a big neighborhood
- SPF = List of Approved Delivery Guys
- DKIM = Signature on the package, puts a tamper-proof signature on each mail you send
- DMARC = The House Rules on What to Do with fake mail, decides what happens to suspicious mail
For Subnetting,
 Imagine a big city (a network) with thousands of houses (IP addresses). If the city is too big, managing houses becomes confusing.So we create suburbs/subdivisions (subnets)
Cryptography- Locking a Message in a Box with a Key, anything is secure because of it

Though not enough info but it assist students to understand underlying idea.

A+ netwrok+ Security+ challenging areas

M
Hi All,

We are looking to focus some of our training in 2026 and I'd be interested to know if you as a community have identified specific concepts with the domains for A+ Network+ and Security+ that always cause learners problems.

eg in A+ and Network+ we often find that our learners struggle with the DNS concepts more than most others.

Do you find there are key subjects you always have to go over or explain in more details across the above three certifications.

I appreciate this is a little vague but I would value the community's thoughts and feedback.

Many thanks

Mark

Extend Certmaster Access from This Past Linux+ TTT?

Shea Bennett
@Stephen Schneiter Is there any way possible to extend access to Certmaster for Linux+ from the TTT to like 12/31/2025? Many of us activated early (not knowing it would cut off quickly) and I want to be able to finish but the cutoff is 12/13/2025. I want to make sure I'm learning exactly what my students will experience on the Certmaster platform. I'm almost done, but need a little more time (like some others who joined the TTT session).

Is this possible at all?

Do the Linux+ vouchers seem possible before New Years?

Linux+ XK0-006 vs. 005...?

I completely agree! I have been asked to take the newest version of an exam once, but when I told the training provider (who is known for not paying very well) that my certs were current, and I would only take the new exam if they provided me a voucher, they demurred. With that said, you have clearly been in the CompTIA world MUCH longer than I! I took my first CompTIA exam in 2021... so yes, I could take the new A+ Net+ Sec+ CySA+ if needed, but they would only be one version off from what I originally taught. My Linux+ and SecurityX certs are the current version... but only because I just sat them! :)

For the first couple of years I framed my certs. I eventually threw them out. I also want to learn what is useful, but the reality is a lot of companies want us to hold certifications for the classes we teach.

It never made any sense to me why some clients insisted that I constantly retest every time a new version of a CompTIA exam was released. I have six Security+ versions, five Network+ versions, four A+ versions, three CySA+ versions, two Cloud+ versions, two CASP+/SecurityX versions, two ITF+/Tech+ versions, and two Project+ versions. None of my clients have ever asked me to retest for Microsoft, ISC2, or ISACA. Only CompTIA.

I'm done with that. If I have a CompTIA cert, I'll maintain it with CEUs but I'm never retaking an exam for something I already hold ever again.

Thank you! Yes, I have failed Microsoft a lot, VMware a couple of times (renewals only)... but never a CompTIA, ISC2, or CSA exam. As for keeping records... how could I not? It is so important to measuring one's progression :)

I quit counting after the first 60. Microsoft, CompTIA, Axelos, PMI, ISC2, ISACA, CertNexus, ScrumStudy, Certiport, CSA, CIWCertified, and some others that I've forgotten. I no longer care about getting another piece of paper to shove in a folder and care more about learning something new and useful.

In my career I have sat 114 exams, and have passed 78 of them. (In the early days when I was getting free vouchers from Microsoft I failed a lot... my current streak since November 2017 is 29 passed, 3 failed (two of which I'd already passed but tried a new beta version, the other I failed on Thursday then passed on Saturday). My point is that of my 78 passes, I have scored perfect ONCE. I remind my students that the guy who graduates last in his med school class is called Doctor, and that nobody will ever see your score reports... unless you are an instructor showing them they don't have to be perfect. I did not lose sleep but I did have a lot on my mind and I still passed, and I'll take it.

I do follow those strategies that I teach... and it worked ;)

(It is a bit more nerve-wracking because of the 39 failed exams... not one of them was a CompTIA exam. I like to be able to show my CompTIA students my PearsonVUE Exam History page with the 9 passes (and one Cancellation). They should at least see a clean sweep there :))
