Which methods in the TCS SAPI can be used to prevent Path Traversal?

  1. isValidDirectory( java.lang.String context, java.lang.String input)

  2. isValidDirectory( java.lang.String context, java.lang.String input) and isValidFileName(java.lang.String context, java.lang.String input)

  3. isSafeDirectoryPath(java.lang.String context, java.lang.String input,boolean allowNull) and isSafeFileName(java.lang.String context, java.lang.String input,boolean allowNull)

  4. ValidateDirectoryPath(java.lang.String context, java.lang.String input,boolean allowNull)

C Correct answer
Explanation

To prevent path traversal attacks, TCS SAPI provides isSafeDirectoryPath() and isSafeFileName(). Both methods take a context, input string, and allowNull flag. The 'isSafe' prefix methods (option C) are the correct API methods for validating path safety.
