Just because I like giving more money to Pearson Vue, I took the BCMSN test today to see how I would do.  I passed with no problem.

In my mind, the CCNP is a technical certification, so I expect to be tested on technical topics.  Are there topics beyond technology that P-levels should know?  Of course there are, but I really don’t think whole chunks of the test should be about a preparation plan and rollback procedures.  The BCMSN had a lot more technical questions at a much higher level of expertise; it seems much better suited to the CCNP track than the SWITCH test did.

I did my standard 2ish-hour drive to the closest testing center today to take the SWTCH test (642-813).  Utter failure.  That’s 3 for those scoring at home.

The test was the absolute worst I’ve ever taken.  I know that I complain a lot, but this is totally justified in my eyes.  My 4th grade spelling tests were better than this.  I’ve seen kindergarten plays with better production value.

First of all, it was poorly written.  Whoever wrote those questions has a few pieces of information about English sentence structure missing from their skill set.  A sentence needs a verb, right?  Well, a lot of the sentences were missing those.  It’s kind of important to know what the whole point of the sentence is, or is that too much to ask?  The “drag this over here” exercise questions all started with the same 13-word phrase that left the question so long that it was unreadable.  A couple of commas would have been nice in some.  Others I just had to infer from the answers what they were trying to ask.

Did you guys have any trouble with the solution to the STP exercise?  Let’s work through it and see what happens.  I got a few responses to the solution, and everyone seems to get the same answer, so I assume we’re all right.

Before we get started, I wanted to mention the tie breakers since there can be ties in STP.  If there is a tie in any calculation, the same tie breakers are used, so I’ll list them here to use as we move through the calculations.

Here’s an STP exercise for you.  Given the bridge priorities, MAC addresses, and interface types in the diagram, calculate the root bridge, root ports, designated ports, and blocked ports.  You can click on the image to enlarge it.  I’ll post a solution in the next few days.  As always, feel free to comment and ridicule my utter idiocy.  Be gentle, though; I don’t usually post exercises like this.
