合格保障：學員若考試不合格，本中心均會代付考試費，令學員可 半費重考 ！詳情...

JNCIS-ENT 其實是由 Juniper Networks 頒發的一項國際認可高級 (Specialist) 證書。高級證書意即你不能直接考取 JNCIS-ENT，而必須首先考取到 Juniper Networks 的初級證書 JNCIA-Junos，才可考取 JNCIS-ENT！

於本課程修畢後通過以下一個 JNCIS-ENT 考試科目：

再加上首先通過以下一個 JNCIA-JunOS 考試科目：

便可獲 Juniper Networks 頒發 JNCIS-ENT 國際認可證書。

註：
通過上述 JNCIA-JunOS 考試科目 (即 JN0-104)，你便可獲發 JNCIA-JunOS 國際認可證書，詳情可參閱 Juniper Networks JNCIA-Junos 國際認可證書課程。

本中心為 Juniper Networks 指定的 JNCIS-ENT 考試試場，報考時請致電本中心，登記欲報考之科目考試編號、考試日期及時間 (最快可即日報考)。臨考試前要出示身份證及繳付考試費 HK$2,460。

考試題目由澳洲考試中心傳送到你要應考的電腦，考試時以電腦作答。所有考試題目均為英文，而大多數的考試題目為單項選擇題 (意即 O) 或多項選擇題 (意即 口)。作答完成後會立即出現你的分數，結果即考即知！考試不合格便可重新報考，不限次數。欲知道作答時間、題目總數、合格分數等詳細考試資料，可瀏覽本中心網頁 "各科考試分數資料"。
