The exam information about CCNP

The Composite exam (642-892) is the quickest way for currently certified Cisco Certified Network Professionals (CCNP®) and Cisco Certified Design Professionals (CCDP®) to obtain recertification. The exam tests skills and knowledge pertaining to the Building Scalable Cisco Internetworks (BSCI) and Building Cisco Managed Switched Networks (BCMSN) courses. Composite may be taken to recertify CCNP and CCDP certifications; it may also be taken in place of the BSCI and BCMSN exams required for CCNP and CCDP certifications. Candidates must successfully pass both routing and switching subsections of the Composite exam to successfully pass the exam.

獲得SCJP認證心得

深刻理解面向對象的思想
Java是壹種純粹的面向對象的程序設計語言。在正式使用Java做開發之前,必須將我們的思維方式轉入壹個徹底的面向對象的世界。做不到這壹點,就無法體會Java語言的精髓,寫不出地道的Java程序。當然,妳也無法徹底理解Java中的基本概念和他們之間的聯系與區別。妳可以學到Java的語法規則,卻不能看到Java的靈魂。

對概念細節的精確把握

通過考試我們發現,SCJP的考察點相當細致。所以只有對Java的概念、語法、規則了然於心,才能在考場上應對自如。

適量的練習
程序設計是壹項實踐性很強的技術。只有上機實踐,才能使課本中的理論、頭腦中的思想通過妳的雙手成為壹行行代碼,完成規定的目標。雖然SCJP考試不考操作與編程,但有大量的程序閱讀。如果妳自己寫過許多代碼的話,這種題就是小菜壹碟。

廣泛的交流
善於交流是優秀程序員必備的技能,也是妳解決疑難,提高水平的捷徑。國內外有很多與Java認證相關的優秀網站和論壇,如: www.javaranch.com, www.javaunion.net等, 都是學習Java的寶庫。同時,壹些很棒的模考軟件,如Jxam、JTest、 Javacert等,以及著名的模考題如MarcusGreen的三套題均可以找到。
