Network+ stuff, some of it was harder

This is the third time ive sat down to try and write this and im not sure what the hold up is but perhaps this time, ill actually get through it. I meet with a personal trainer today and to be honest I have no idea what im doing in a gym and im hella out of shape. They gave me a really good deal so I guess I’m meeting with a trainer 2-3 times a week for the next year for group and individual meetings. Awesome. Anyway lets get back into Studying. I’m really excited about life right now haha, anyway.

So the answer is simple enough but I have no idea about this stuff and want to know why its working like this. Update, after doing some research this appears to be a red herring question because there is no diagram that I am finding that looks like this. This is usually a good indicator that while these questions may cover the topics at hand they will not necessarily be on the test. I have never taken a CompTia test before I can say thats how msft stuff works so when I’m doing going through this I wont wast time memorizing answers and will seek additional resources before testing. However, it would be nice to know what it looks like when you use a cable tester to get certain results and what those mean.

This is really just a question of listing shit out. I dont know what any of this is but im sure if I did the document choice would be obvious.

  • AUP – Acceptable use policy
  • SLA – Service level agreement
  • SOW – Statement of work
  • Security Policy – Security policy is a definition of what it means to be secure for a system, organization or other entity. For systems, the security policy addresses constraints on functions and flow among them, constraints on access by external systems and adversaries including programs and access to data by people.

Yeah thats obvious.

No idea what any of these things are other than an SLA so it’s possibly a good idea to learn what they are.

  • MSA – Medicare savings account? ok, so when i google the test it comes up with master service agreement
  • MOU – Memo of understanding
  • SLA – Service level agrement
  • AUP – Acceptable use policy

Again, that seems fairly reasonable.

  • AAA configuration – ok, so im slightly confused by this but apparently this is a method for logging into routers deployed in a network to make changes
  • Port Mirroring – mirrors traffic on two ports
  • Virtual terminal configuration – fancy way of saying pop a shell, based on this “For example, applications can use a character-based presentation service called the Network Virtual Terminal (NVT), part of the Internet’s telnet remote access specification”
  • Tagged VLAN configuration – VLAN tagging is a method through which more than one VLAN is handled on a port. VLAN tagging is used to tell which packet belongs to which VLAN on the other side. To make recognition easier, a packet is tagged with a VLAN tag in the Ethernet frame.
  • Out-of-band management – In systems management, out-of-band management involves the use of management interfaces for managing servers and networking equipment. Out-of-band management allows the network operator to establish trust boundaries in accessing the management function to apply it to network resources

There are some debatable things going on here. Even for a person that doesn’t know much about networking but like the last one…involves a cable, and possibly a really long cable, that possibly goes over Ethernet at some point haha, ok right, thats different than remotely logging in with an id and password to open a shell.

Shockingly, I dont know a damn thing about this, there are ports and numbers and it all looks like a bunch of nonsense to me. So lets start with the words around the numbers.

  • sport – source port
  • srcip – source IP
  • dstip – destination ip
  • dport – destination port

That’s a helpful starting point. Honestly still kind of confused about the methodology. I think that beyond the basics there are some os specific syntax’s involved that will require a much larger base for me for me to understand. so “D and E”

Honestly, I have no idea why I added this. All the info is kind of debatable but i feel like forgetting the word ‘off site’ in the backup plain is problem.

Anyway, this took a while to write but there was a lot to unpack. I suppose that should be frustrating or something but welcome to the learning process for the people that refuse to be uneducated and are not overly concerned about the absurdity of existence. Its usually the gate keepers that are worried about you rather than the other way around. To be honest, if they are not intelligent I don’t really care what they have to say and odds are good that they will never read this or be concerned by something that’s actually interesting.
