CCIE SP OEQは本当らしい

直接サポートセンターに訊いた所どうやらＯＥＱは本当にやるそうです。
となると一日でも早く練習問題が開発完了できるようにワークブックのベンダに催促のメールでも送るとするか。


Dear ***,

Thank you for contacting the Certification & Communities Online Support Center.

I do apologize for your inconvenience but the CCIE team has not decided to add this new feature to the CCIE announcements page.

I have pasted below the email that was sent out to all the Learning@Cisco candidates with all the information available on the CCIE Core Knowledge Question change.

Core Knowledge Questions Now on All CCIE Labs

Effective January 4, 2010, the CCIE® Service Provider, Storage, and Wireless Lab Exams will add a new type of question format in a section called Core Knowledge. In this new section, candidates will be asked a series of four open-ended questions which require a short written response be entered into the computer--typically several words. The questions will be randomly drawn from a pool of questions on topics eligible for testing. Candidates can review the topics by visiting the CCIE track information on Cisco.com or Cisco Learning Network. No new topics are being added as a result of this change. Candidates will have up to 30 minutes to complete the Core Knowledge section and may not return to it once they have moved on. A passing score on the Core Knowledge section is required to achieve certification. Core Knowledge questions were implemented on Routing and Switching labs in February 2009, Security labs in June 2009, and Voice labs in July 2009, and allow Cisco to maintain strong exam security and ensure only qualified candidates are awarded CCIE certification. Candidates with exam dates January 4, 2010 or later should expect to see the new question format on their lab exam.

To find out more information regarding updates to the CCIE Lab and scoring format, please click here to go to the CCIE Q&A section.

Core Knowledge Questions Now on All CCIE Labs

２０１０年１月４日より全てのCCIEトラックにOEQ(Open-End-Questions)が追加されるらしい。

Cisco Learningのニュースレターが元情報らしいけど自分にはそんなメール受け取っていないし、現時点での公式ページにもそのような情報はない。CCIEメーリングリストも先週かなり議論になってました。Internet Expertも来週中に模擬問題を出すらしい。

基本的に普通に勉強していれば問題ないとおもうが、念のためシスコプレスを読み返すことが必要となりそうだ。特にど忘れしているボキャブラリーのメモリー再構築をしないといかん。

OEQは４問中３問以上正解しないと自動的にラボ不合格となる。OEQの配点は２１点で０点か２１点の２通りしかないらしい。ラボの配点は残りの７９点となる。合格点は８０点以上なのでどんなにラボをがんばって満点とってもOEQで失敗するとだめなわけ。

考え方によればOEQでラボ試験が簡単になったともいえるわけです。なぜならOEQで２１点とれれば、合格点まであと８０－２１＝５９点をラボセクションからとればいいわけで、ラボセクションの配点は７９点なので、（５９／７９）＊１００＝７４．６８％の得点率で合格できる計算、これは従来の８０％から見れば合格ボーダーラインが５％下がったことになる。
