True we need to prepare well. Before we teach.Certifications are proof you can achieve a passing criteria on a standardized exam. Mastery takes much more than passing an exam.
I work twice as hard preparing to teach a class than I ever do preparing to pass an exam.
Right there with you. I'm sitting in the General Session for Anthology Together 24 in Orlando and they're talking about how AI is even rewriting Moore's Law in capability.I have a fundamental zero trust on almost everything.
But since I'm nowhere close to retirement and it appears that AI will have an increased presence in the future, I plan on learning as much as I can about it so that I can help others use it safely, securely, and ethically.
We will take note of this thank youi would recommend the Sybex Security+ book to learn and prepare for your exam
You are welcomeThank you for the reminder I have a note already in my Google diary, see you online later tonight (UK time 20:00)
Congratulation sir,I was honored to be chosen to be among the first to acquiree the CloudNetX inception version certification. I completed the exam today.
Advanced cloud networking skills across multiple providers, particularly cloud connectivity technologies and solutions such as VXLAN, GENEVE, CMDB, ZTNA, Wifi-6, WPA3, Wireguard VPN, DEVOPS, IaC Resource provisioning and configuration, Version Control secrets management, and QoS, were heavily featured in the exam.
Some Performance Based Questions were slightly difficult, while others were outright simple if you have actual cloud networking abilities, particularly in VPC peering, WAF, Application Gateway, and NSG configuration.
It was a rewarding challenge that I eagerly accepted to supplement my practical abilities across a wide range of cloud technologies, and I am confident of passing when the results of this beta exam are revealed in January 2025.

Question 5 states:
5. A company has eight networks, using the subnet addresses 192.168.0.0/24,
192.168.1.0/24 … 192.168.7.0/24. What network prefix and subnet mask can be used to summarize a
supernet route to these networks?
Answer:
It takes 3 bits to summarize eight networks (23 = 8). Subtracting 3 bits from the existing network
mask makes the supernet network prefix /21. The third octet of the mask will use 5 bits, which is
248 in decimal (25 = 248), so the full mask is 255.255.248.0.
This class is unable to grasp this concept, & I am running out of ways to explain & time to stay on track to finish class where I need to for the day. Any help explaining is greatly appreciated.

I have a fundamental zero trust on almost everything.This is why I am going to be on the trailing edge of the entire AI party.
It really is a fundamental level of trust.

I appreciate the answer, I will give it a try! I came up with 3 separate explanations off my head similar to this but it just won't stick. I am going to need a new set of whiteboard markers, & some hair dye to undo the intellectual war that occurred today.Okay, let's imagine this like a big game of organizing candy!
You have 8 different boxes of candy. Each box has its special number, like 192.168.0, 192.168.1, and so on, up to 192.168.7.
Now, your mom wants to put all these boxes into one big container. She needs to find a way to label this container so that it includes all the smaller boxes inside.
The trick is to look at the numbers and see what they all have in common. In this case, they all start with 192.168, right? That's like saying all the candy is chocolate!
But we need to be a bit more specific. We notice that the last number changes from 0 to 7. In computer language, this is like saying we need the first 21 bits to be the same (because 21 bits can describe all numbers from 0 to 7).
So, the label for the big container (what grown-ups call a "supernet route") would be:
- Network prefix: 192.168.0.0
- Subnet mask: 255.255.248.0
This is like saying "This big box contains all the chocolate candy numbered from 0 to 7!"
