      @Pete-S said in YAML terminology and Ansible:

      Other than that it doesn't matter to me what anyone calls it.

      You are 100% to call it whatever you want. But a key/value pair is commonly referred to as a dictionary... or a hash table which is a dictionary data type. This isn't exclusive to Python in the least.

      "Commonly referred" depends on the programming language in question. For example in many other languages it's commonly called an array or collection and never a dictionary.

      If you look at the part you quoted, YAML calls it mappings.

      The proper computer science terminology would be associative array.
      https://en.wikipedia.org/wiki/Associative_array

      The best thing to do is to call it exactly what the language or software you are referring to calls it. If Ansible wants you to create what it has named in their documentation as a dictionary in YAML, that's what you refer to it as. Otherwise, someone who is familiar with Ansible and it's documentation won't know what the hell you are talking about if you call it your own thing.

      I can agree with that point of view - YAML in the context of Ansible.
      https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html

      So you'd call it dictionaries then. And lists.

      Network Documentation is very very important, for Network Admins is a must, because for example a new team member joins, this information will be useful to acknowledge the network infrastructure.

      I have experienced that T3 (DS3) collapses (saturates) once you reach 40 Mbps, even rate is up to 44 Mbps.

      But I'm literally 100% confident given your description, that you are perceiving it as people using "cell phones" to replace VoIP, and not realizing that it's standard VoIP softphones being deployed onto mobile computing devices that are often, but not required to be, cell phones.

      We have cisco everything and I was told it was too expensive to have softphones on our cell, we instead must have a separate cell phone. I doubt that, but who knows.

      And yet it wasn't too expensive to have Cisco... suspicious.

      yep, agree!

      @JaredBusch said in Optical Fiber - CompTIA Network+ N10-007 Prof. Messer:

      The point was that it is cheaper to buy pre-terminated fiber in the lengths needed instead of buying fiber and getting it terminated.

      Not that does not apply universally. It does apply for most office buildings.

      Where he is, I have random conversations with people who are like "Oh yeah, I trenched across town myself." Things you never hear here. There is actually a lot of self termination, lol.

      @mary It depends on what you have, some Cisco Switches came with GBIC others (now in time) come with SPF.

      And now SFP+

      (SPF is sunscreen levels, SFP/SFP+ are the adapters.)

      Worth noting that STP (Spanning Tree) is common in good switches, but it's also common to have switches that don't have it.

      In one of the companies that I worked, they have an "Initial Test" for any Engenier;

      They ask you, Are you an Engenier?, then do a Patch cord, here are the tools, make 1 with B Standard.

      That is the way to show that you are a good engenier... jajaja

      In network almost every core device (routers, switches and servers) may be NTP Master or Server. It depends on network design who will be the NTP Master, for me is the device which is "closest" to Internet.

      @Dashrender said in IPv6 Subnet Masks - CompTIA Network+ N10-007 Prof. Messer:

      It's absolutely true that IPv6 gives us billions and billions of small networks worth of IPs(each of those smalls being likely larger than the full IPv4)

      Right, both are just a flexible pool. One is just way, way bigger.

      @mary said in Network Topologies - CompTIA Network+ N10-007 Prof. Messer:

      Did I understand him correctly saying there are still ring networks used by metropolitan areas?

      Resilient fiber networks frequently have two fibers - one going in each direction. It's often called a fiber ring.

      But should not be, that's not a ring.

      Yes, it is. Looks like this for example:

      alt text

      Network topology is a ring. But it's still good ol' ethernet.

      I believe each blue line is a bidirectional link. So that each switch has two incoming links and two outgoing links. This type of topology is very common for a backbone where you have long distances. While a full mesh network is more resilient it requires a lot more fiber.

      @melvinsilva said in Spanning Tree Protocol - CompTIA Network+ N10-007 Prof Messer:

      I had experience when "users" manipulate patch panel or switch and plug both end of the cable (patch cord) to the same switch, creating a physical loop, but STP blocks this and prevent network issues.

      Yeah, having switches that have STP turned on by default can be such a life saver in those situations. One place I worked liked to put in unmanaged switches all over the place. Caused me multiple long nights just tracking down which switch was the issue and then finding the loop cable. I knew exactly what was going on, finding it without good documentation and people saying "Oh, there's another network thingy over here." was just so much.... fun.
