Over the weekend, I took a couple of the newly released poly labs from Internetwork Expert. Since I haven’t really seen anyone write about them yet, I thought that I would share my experiences.
For those of you out there that have purchased the CCIE 2.0 product, it comes with unlimited labs. In other words, you don’t have to pay any tokens just to generate a lab. For non-CCIE 2.0 owners, it’s 25 tokens (which is $25 without any bulk purchase discounts). When you create your lab, you can rate yourself in about 7 different topic ares (like switching, multicast, QoS, etc). The higher you rate yourself, the tougher the tasks should be in that particular section. Once you rate yourself, you click on Generate. About 10-20 seconds later, you have a lab waiting your you.
After creating your lab, you can open it up and view the rules and lab tasks. The last thing that you need to do to actually take the lab is to rent some rack time from Graded Labs. Once you have some active rack time going, you can go back to your Poly Lab page and click Setup. This will kick off their process of loading the initial lab config on your rack. This can take 10-20 minutes or so. It’s a good time to start going through your lab tasks and make some notes. Once it’s done setting up the rack, you then click Start and a timer begins. IE suggests an estimated completion time for your lab, which is what the timer is based off of. You don’t have to finish in the allotted time. But it helps to simulate a real lab.
Now that the lab has started, you can remote into your rack and go to town. When you’re done, go back to your Poly Lab page and choose to grade your lab. This takes 5-10 minutes. After that, you get a score report and a task by task breakdown. That’s it! After all is said and done, you can go back into your rack if you still have some time left over on your rental and do whatever you want.
So that’s the overall basics of the Poly lab. Now for my experience…
Since this was my first multiprotocol lab, I thought I’d just start off with a beginner rating on all of the sections. I generated my lab and clicked on Setup. I walked away while this was happening and when I came back, I was back at the main poly lab page. But, it didn’t have a start button for me to click. Evidently something went wrong during the rack setup process. After waiting for a while longer, I just went in to the rack and saw that it looked like everything had been setup. So I went through the lab. Unfortunately, I wasn’t able to have it graded. I did contact support on this, and since I saved my configs at the end, they are going to load them up on a rack and grade it for me so I can see my results.
The next day, I thought I’d try again. So I whipped up a new poly lab and ran the setup. This time everything worked as expected. I whipped through the lab and was able to get it graded. Overall, I thought the grading was done quite well. It breaks down each task section and lets you know what was right and wrong. It also allows you to see what the criteria used for grading was, what you did, and what the correct answer was. So it’s very helpful in showing you where you went wrong and how you should have been verifying things. Based on your performance, the grading engine gives you a ranking in each topic category, which you can use the next time that you want to generate a lab. You also get links to materials that you can study from to improve based on your skill level.
Outside of the rack setup issue I had, I was pretty impressed with the product. I see myself using it on a fairly regular basis. The other workbook labs are great. But it is nice to be able to customize things at your skill level.
So what did I score? Well, it wasn’t very impressive. I only got a 55%. But had I read a little closer and known what “best practices” was referring to, I would have gotten around a 75%. Those were more reading mistakes, and not lack of knowledge of how to configure things. But I did get utterly spanked on the security, QoS, and IP services sections. I don’t know what it is about those topics, but I always feel like an R-tard trying to solve them. There are just so many little nuances to know. But I did nail the core topics. I’d rather it be that than the other way around.
It’s definitely a good tool that I would recommend people should check out. It’s got a similar feel to the real lab environment. Plus you get the automated grading. No need to figure out through a proctor guide if you really got the points or not. Also, there’s just something about being ranked that makes you want to do better the next time. Maybe it stems from countless hours playing RPGs and trying to level up. I don’t want to stop until I’m an expert in each topic area. =)
