After moving data to a new filesystem, how can the former path of the data be kept intact in order to avoid reconfiguration of existing applications? (Choose TWO correct answers.)



A. By creating an ACL redirection from the old to the new path of the data.
B. By creating a hard link from the old to the new path of the data.
C. By creating a symbolic link from the old to the new path of the data.
D. By running the command touch on the old path.
E. By mounting the new filesystem on the original path of the data.

題解

選項A,ACL可以提供特殊的檔案權限設定,和檔案路徑與檔案重新導向並沒有關聯。

選項B,實體連結(hard link)只能用在同一個檔案系統下。

選項C,符號連結(symbolic link)可以用在不同檔案系統下。為正確答案。

選項D,「touch」指令會產生新檔案或是改變舊有檔案的修改時間。

選項E,將不同檔案系統掛載到同一個路徑下,對於單純存取檔案的應用程式來說並不會感到任何差異。為正確答案。
