Guys, don't feel bad. Even CCNP is messed up.
Good men and girls. This is a story from work, so you won't feel too bad or too scared because of messing with test questions or even at work. It happened. Even CCNP engineers sometimes laugh.
Plan to make a simple upgrade for one of our "remote" sites (technically located at the hotel, but about a 1/3 mile away). This is a building.
Somehow, I don't know how. These fools have a brilliant idea of moving the Cat6 from a separate operation through the facility, from our main facility to other places where it needs to go. problem? It is like 400 feet. Obviously, it failed because the maximum distance of copper is 100 meters / 328 feet. The entire facility no longer appears on my monitoring tools. Out of service. Guess what is the connection service? The safety system of the facility. So the facility is actually not safe until they return to the old line (T1 I think?).
So you all tell me why you should be frustrated by messing up or not understanding what you just learned. When CCNP or 3 can not only get the plan through their own minds, but also through the entire change consulting process, some people say, “ Um... dude..." It's like the first week of Net+ or the second day of CCENT. People, this is a simple matter.
Then the engineer launched another project at the time w / statically assigned IP on the interface forgot to copy the start of the run, and the device restarted on the weekend. This is an interesting Monday.
So stick to it, don't beat yourself, have fun! People are not sages.
