上星期三我到芝加哥去坐火车CCDE实用Beta考试。总的来说，这是一次测试。它有一些粗糙的边缘需要清理后才能投入使用，但它的路线是正确的。考试开始前30分钟，我来到了皮尔森专业考试中心，办理了登机手续。如果你没有在皮尔森专业中心参加过考试，你会立刻注意到差异。两年前，我在一家类似的培生专业中心参加过GMAT考试，我很快注意到他们的考试质量和我一样高。你签到，拿到一个储物柜，并被要求坐下来等待。您将被亲自护送到测试区，并准备参加基于计算机的测试。当你参加考试时，你会被摄像机和监考人员监控。需要严格的安静，休息时你会被护送进出房间。 ID is required at all times and is checked when you return from breaks. We all took a break at noon for lunch and were escorted downstairs to a restaurant where we were not allowed to discuss the exam (makes sense). However, even after the exam we were not allowed to discuss it (a little over the top, but definitely keeping with their security style). Overall, the logistics of the exam were handled very well. The test itself was,正如我所料，很强硬，但并非不可能。复习一下ISIS和MPLS可能会有所帮助，但这并非遥不可及。它是不同场景的六个部分，如建立一个新的网络，改变路由协议，等等。其中最困难的部分是8个小时的计算机测试。即使考试不全是选择题，你也要把注意力集中在考试上。我的思绪不时飘忽不定。但是，8小时的测试是完美的。你必须继续前进，但你有时间完成它。我还剩20分钟就完成了。测试本身也有一些困难。 There were a few questions that just didn't work, like one that was just a blank screen. Others had the wrong type of selections (radio button instead of multiple choice). But, those errors were minor and to be expected in a beta. The bigger challenge was the ambiguity of some of the questions. I'm sure the goal of some of the questions was to be ambiguous to make you think and research the documents more, but some could easily be interpreted in two different ways, leading to correct, yet wrong answers. Cisco has noted in the past that, in some places, there are multiple right answers. Some right solutions might be worth more points than other right solutions. Still, I think this needs to be cleaned up a bit more. Ambiguity - even two solutions - is good, confusion is not. The questions need to be easily understandable so as to put the tester on the right path, even if they choose a slightly different solution for partial points. I wasn't able to attend the party afterwards since my flight was three hours after the test. I heard it was a good time with a great view of downtown Chicago. (NOTE to CCDE Team: please announce parties more than 24 hours before test in the future. Then we can schedule flights appropriately.) ;-) Results are in 6-8 weeks. Cross your fingers.
