I've never used the tac command. I know it, just never used it.

The common commands I use for viewing the contents of a file are cat, less, more, head, tail, nano and vim. All of the commands I've mentioned are in the exam objectives for Linux+. I'm not sure about tac.

grep is a command that is very common in many of the CompTIA exams whether, it'd be for Linux+, Security+, CySA+, Pentest+ and even SecurityX (formerly CASP+). I personally use grep in many scripts.

aside from grep, I also suggest knowing sed and awk

Amazing session for the new Linux+ v.8 (006) exam TTT session today 9/11/2025.

Jason went over the tac command and many other options. I'm not even embarrassed to say I have never used the tac command or searched in files with grep. Excellent and eye opening session. I truly and completely appreciate going back to the roots and fundamentals. One thing I will say about Linux I truly love and enjoy. You never stop learning!

Oracle Virtualbox is easier to use and the load is lighter than Hyper-V. When I setup my classes, I'm using native Linux to really deep dive for real world ops. We don't have any Hyper-V in any of our datacenters. Only AWS/GCP Cloud, RHEL/Rocky Linux, Oracle Linux and VMware, OpenStack or Proxmox. So, unless your a primarily Windows shop. I wouldn't use it.

Hyper-V is a Type 1 (bare-metal) hypervisor that comes with Windows Pro and higher editions (though it can be installed on Home if you look up how). Being Type 1 means Hyper-V runs directly on the hardware, with a lightweight virtualization layer in between. This allows near-native performance.

In contrast, Oracle VirtualBox is a Type 2 (hosted) hypervisor by default—it runs as a regular application on top of Windows. As a result, all VM hardware access must go through the Windows OS first, which adds overhead and reduces performance compared to Type 1 hypervisors.

So, in general, Hyper-V is faster than VirtualBox by default.

However, there’s a neat trick: if you have both Hyper-V and VirtualBox installed, you can configure VirtualBox to use Hyper-V as its backend. To do this:

Open the settings for your VirtualBox VM,

Go to System > Acceleration,

Set Paravirtualization Interface to Hyper-V.

This allows VirtualBox to leverage Hyper-V’s performance benefits while maintaining VirtualBox’s compatibility and features.

Why is this useful? In cybersecurity, many pre-built VM targets and OS images are packaged specifically for VirtualBox. So for students taking a cybersecurity course, it makes sense to use VirtualBox—but enabling Hyper-V paravirtualization gives the best of both worlds: broad compatibility and improved performance.

If you're not teaching a cybersecurity course, however, it makes sense to have a simpler setup where you just stick with Hyper-V for faster, cleaner VM performance on Windows.

I teach numerous cybersecurity and digital forensics courses, which means I often use Kali and Parrot (as discussed in the training), and occasionally CSI Linux. I will try the "Set Paravirtualization Interface to Hyper-V" before the class tonight and do a few labs to see. Thanks.

Overall, I like them both. I've used both and both are great platforms for different reasons. Also, KVM is a good tool for long-term virtualization projects.

For the labs, I chose to do them on Oracle VB. My students or clients are not always on Windows Host OS

@Stephen Schneiter When is CompTIA Data + Beta results coming out

sharma_sid · 2025-09-11T13:51:00-0500

We all know data is the backbone of every modern business. But with data growing faster than ever, making sense of it all can feel overwhelming. That’s where Large Language Models (LLMs) like ChatGPT come into play — they’re not just tech buzzwords, they’re game-changers.

If you’re preparing for the CompTIA Data+ certification or working in data roles, combining your data skills with LLM-powered tools can take your career to the next level.

Here’s how LLMs help in the data world:

Turn everyday questions into structured data insights — just ask in plain English and get answers.
Generate clean, easy-to-understand reports in a flash.
Get smart suggestions for fixing messy or incomplete data.
Automatically help with data governance and compliance tasks.

The future is already here. Companies are moving beyond spreadsheets and dashboards — they’re using AI to speed up data analysis and make smarter decisions faster.

If you combine the solid foundation of CompTIA Data+ skills with the power of LLMs, you’ll not only pass the exam but be ready for real-world challenges.
The demand for data pros who can work with AI is only going to grow. So, why wait? Let’s make data easier, smarter, and more human.

I realize that - and I thought I mentioned that in my previous post - which is why I always argued about what it looks like based on what it does.

I always debated this point en principio - of whether Hyper-V was a true type 1 hypervisor, because it requires Windows to be loaded as the OS before the hypervisor runs. Now, other folks would say, "Hyper-V is part of the Windows OS", so by extension, makes it Type 1, etc etc. I know MSFT claims that when Hyper-V is loaded, it adds a hypervisor layer to run on bare-metal and the "host" Windows OS becomes 'virtualized'.

Hurts my head, sometimes...

Hyper-V is definitely a Type 1 hypervisor, even though it comes with the Windows operating system. This is because it sits underneath the Windows host OS once you install it as shown below. This is also why, when you install Hyper-V for the first time on Windows, it reboots to load Hyper-V before loading the Windows OS, and why your host OS IP configuration is no longer set on your physical NIC, but on a virtual NIC that references the physical NIC via the underlying Hyper-V (just like other virtual machines). In a Type 1 hypervisor, the host OS is merely an auto-loaded virtual machine that can also manage the hypervisor (i.e., has Hyper-V Manager) and equally shares access to the hardware with all other virtual machines on the system.

Great session today, Jason. Back on the issue of HyperV vs. Oracle Box, can someone share their preference and why?

Hi, everyone,

I passed my Network+ in June 2024. In July, I took the Train The Trainer for Network+ 10-009 (I had tested under the 008 test). It was ten sessions for a total of 20 CEU credits. My question is what other TTT courses would count towards the Network+ CEU credits? Would DataX, Security+, or others count?

Thanks and have a great night.
Patrick.

Refer to this link. https://www.comptia.org/en-us/resources/ce/choose/renewal-options/
It provides a table re: What Renewal Options Are Available to You

I hope this helps!

For me, the choice of hypervisor depends on the cohort:

If the student is new to virtualization, I prefer to use Oracle VirtualBox

If the cohorts are professionals:

Hyper-V if the client is using Microsoft-based products, or KVM if they are into Linux
I've used VMware workstation and/or VMWare ESXi before, until it was bought by Broadcom
for Type-1 virtualization, I prefer Proxmox

Thank you for the reply. I guess I was hoping for a list of known TTT sessions that cover Network+. That way, I don't have to start participating in various ones only to find out they do (or don't) count towards it.

Have a great night.

I can't imagine anyone wanting to extend Tech+ beyond three years.

That was exactly my input to the survey they sent out! Move forward, not renew Tech+, but with the new for-profit model.....

Wendy Edwards · Wednesday at 2:54 PM

Information regarding Linux+ eBook (and eBooks in general): All eBooks are transitioning to CompTIA's CertMaster platform and rebranded as CertMaster Study. The general release for all English versions of CertMaster Study is October 1, 2025, and will be available on the CompTIA store. With the new version of Linux+ recently released, there will not be an "eBook" for Linux+ V8. Instead, the CertMaster Study version of Linux+ V8 will be available with the other Study products on October 1st. More information coming soon in the Partner Meetups and Newsletters or you may reference this help article: CertMaster Study: What You Need to Know.
