Linux 是一套免費及多功能的作業系統,除了可提供檔案及打印伺服器 (File and Print Server) 之服務外,Linux 又可以用作架設網站伺服器 (Web Server)、郵件伺服器 (Mail Server)、代理人伺服器 (Proxy Server) 等,再加上其高度的穩定性,所以現時受到各方的歡迎。有些公司為了讓 Linux安裝方便,將許多的軟體組合起來與 Linux kernel 包裝成 Linux distributions,這就是我們一般比較常聽到的 Turbolinux、RedHat、Fedora 以及 OpenLinux 等各種不同的 Linux Distributions。不同 Distributions 的基本操作是大同小異的,而本中心會教授現時最流行的 Fedora。

LPI 全名是 Linux Professional Institute,是一個來自加拿大的非牟利 Linux 專業團體。由於 LPI 的考試費用較為合理,考試制度及內容亦較齊全,所以 LPI 的考試制度會比其他 Linux 考試制度更適合香港的實際環境,而我們亦預計會有越來越多人選擇考 LPI 的考試。

最新考試版本 4.5 除了包括考試版本 4.0 中增加的 LDAP 知識外, 也更增加了關於最新硬件、Linux kernel及新版本軟件的技術及知識。

本課程將教授 Linux 網絡的進階操作及管理,能大大強化你的 Linux 技術。修畢本課程後,學員可考取 LPI Level 2 國際認可證書。本課程籌備多時,精心編排。由上堂、溫習、實習、做試題、考試研習至最後考試,均為你度身訂造,作出有系統的編排。務求真正教識你,又令你考試及格。


LPI Level 2


課程時數: 合共 48 小時
適合人士: 已考取 LPI Level I 證書的人士,或已修畢本中心所開辦的「Linux LPI Level 1 國際認可證書課程」。
授課語言: 以廣東話為主,輔以英語
課程筆記: 本中心導師親自編寫英文筆記

1. 模擬考試題目:

本中心為學員提供超過 200 條 LPI Level 2 Exam 模擬試題及標準答案。
2. 導師親自編寫筆記: 由本中心擁有 LPI Level 1、2 及 3 的導師 Mr. Norman Lau 親自編寫筆記絕對適合考試及實際管理 Linux 網絡之用,令你無須「死鋤」如字典般厚及不適合香港讀書格調的書本。
3. 兩科考試合格保障 以 LPI Level 2 Exam 201-450 為例,本中心 LPI 學員於第一次考 LPI Level 2 Exam 201-450 若不合格,可申請 半費重考 LPI Level 2 Exam 201-450 一次,但必須符合下列的四項要求:

1. LPI Level 2 Exam 201-450 課堂出席率須達 85% 或以上。

2. 學員必須於本中心應考 LPI Level 2 Exam 201-450 考試。

3. 學員於第一次應考 LPI Level 2 Exam 201-450 考試前,必須進行本中心的 LPI Level 2 Exam 201-450 試前測驗,並取得 90% 或以上的分數。

4. 於 LPI Level 2 整個課程 (48 小時) 上課結束日之一個月內作出申請。

而 LPI Level 2 Exam 202-450 亦如 LPI Level 2 Exam 201-450 般的安排。

4. 免費重讀: 傳統課堂學員可於課程結束後三個月內免費重看課堂錄影。
