Cisco has a fairly flexible regex for its pipe commands.
The next level up is Terminal shell which has basic Linux utils like grep and cut.
If your on 16.6 then you can run a full RHEL shell so you can do awk and sed and whatever else.
On paper net neutrality is just doing the stuff we already do in the enterprise, we do pay the ISPs more for an MPLS connection that supports QoS etc. So a tiered internet isn’t all that unheard of, though things like support and service calls will get more complicated in this model for residentially.
Saying that no one trusts their residential internet so this will be seen as a pure money/power grab especially with the media conflict of interest.
Typically 3 years but there is nothing stopping Cisco from updating the test if they feel like it.
Saying that if you earn the ccent then your a ccent and will just need to pass the other exam to be a ccna if there is an update.
If a candidate does a cert properly by getting the proper prerequisite experience, doing all the studying and labbing everything then they will be a solid CCNP/CCIE/A+, of course cheating and paper certs is a thing which is why rigorous interviews are very important.
The thing is, the cert itself doesn't do any of this. That's what I'm saying (and you're agreeing) just having the cert means you can pass the test. It boils down to the soft process of interviewing to root out whether or not the candidate knows what they claim. The same can be discerned from another candidate who doesn't have a cert.
It is the framework for studying and the assumed knowledge that I'm arguing for. It helps prevent what I call the "D-link tech" where they just know what they know in their current job.
For example, if you work in a EIGRP only shop and only learned on the job then it is possible that you know nothing about OSPF, also along those lines is that places like NOCs analysts are notorious for skipping over fundamentals in favour of knowing what commands can make the ticket go away. But if you had a CCNA in the same position then it is reasonable to assume that you would at least know the basics.
The problem is most current certification tracks don't prove candidate knowledge, they prove candidate test ability. It's why you ban brain dumps here. If more certification tracks included at least a hands-on portion of the exam, this would be less of a gripe. You've said it yourself memorization and brain dumps cheapen the value of certs.
But if you had a CCNA in the same position then it is reasonable to assume that you would at least know the basics.
If that's the case, why not skip the technical portion of the interview and move straight to "will they fit in the team"?
Even hands on certs can be dumped, it wouldn't be hard to buy the latest RHCE exam if you wanted to. Hell even the CCDE was briefly leaked this year and that exam is only issued several times a year to control the exam (though Cisco went full scorched earth after that)
I wouldn't be surprised if Cisco exams eventually use VIRL or such to replace sims since it will let them make sims harder without much hassle. But certs should always test theory / fundamentals as well as lab stuff rather then just making the CCNA a smaller CCIE TShoot/Config lab.
It is just a safe guard, you don’t need it if your Q-In-Q network has a clean native vlan setup but by just having the switch tag everything you remove the potential for accidents later. Plus it is a good L2 security practice.
What accidents, exactly? That's the question I can't find the answer to(
If you don't pay attention then to your native vlan you might accidentally use the wrong vlans for your Q-in-Q which can cause everything from it not working to weird stuff like dumping the traffic in the middle of the L2 network etc.
Some of this is a bit beyond the CCNA, but it makes a great jumping-off point for further self-study. Taken mostly from the Cisco Live! and OCG. Definitely not comprehensive.

Just an FYI, disabling DNS is a false best practice. People do it to prevent typos from being resolved but it kills the DNS feature which can cause issues, it is better to use
transport preferred none under the lines to prevent that headache.
The rack monkey job is more applicable to network roles, the help desk route mostly just helps out with things like soft skills and getting used to dealing with a large volume of issues and difficult situations.
So if I had to pick between the two which one would you recommend? Keep in mind I certainly want a career in Network Administration/Network Engineer/Network Security.
Either path should work, or even both since the path to true Net Eng is a long one.
The rack monkey path is good because you will at least do some basic things with network devices. It will have a heavy focus on things like cabling, working racks / data centres, installing / swapping cards etc. You’ll also communicate with various network teams so you’ll get the lingo down etc. It will often be on a 24 hour rotation so you could be the guy they call at 3am because NOC can’t talk to a router.
The tech support role tends to be less useful since your often fixing issues where the user is simply an idiot who is trying to login into their toaster oven because they think it’s their monitor. However, it is more common for juniors to go the help desk route. It is more about just getting some kind of IT experience on your resume, it can improve your soft skills and get you used to corporate processes like ticketing every call, using their tools, and dealing with stupid management metrics.
I'd love to see an example
No more than jq < curl | nc after the refactor.
This can really go either way, sure your solution seems like a clean and efficient (at least without knowing the task at hand) but it doesn’t necessary provide things like say error handling.
Of course it goes without saying that scripts can become overly long any number of reasons ranging from poor coding to it simply not being the best tool for the job to the coder just trying to put everything into classes etc.
Anyway doesn’t really seem like python’s fault as much as the wrong tool for the job.
I’m sure it was

No, the only free path is to wait for the scholarship course to start and pass their coursework etc.
what do you mean wait?
Exactly what I said, if you take the test now then your paying for it. It would be no different from anyone else going for the cert.
Cisco will only give the vouchers once you earn it by finishing the course when it starts.
