Which FTP names are recognized as anonymous users in vsftp when the option anonymous_enable is set to yes in the configuration files? (Choose two.)
A. anonymous
B. ftp
C. In the described configuration, any username which neither belongs to an existing user nor has another special meaning is treated as anonymous user.

E. guest
題解
將「anonymous_enable」設為「yes」後，「anonymous」這個使用者名稱，或是被定義在「ftp_username」的所有使用者名稱(預設只有「ftp」)，會被當成匿名使用者帳號。
所以這題答案是選項「A」和選項「B」。
