When an engineer uses Agile Controller to synchronize data, he finds that some user information cannot be synchronized. The user names that cannot be synchronized are as follows:Jack=boss…

Question

Options

• AThe username is too long
• BUsername too short
• CIllegal characters appear in the user name
• DThe user name needs to be composed of numbers and English

• A
  13% (5)
• B
  5% (2)
• C
  80% (32)
• D
  3% (1)

Explanation

Option C is correct because the usernames contain the equals sign (=) - for example, Jack=boss and Mike=leader. The = character is a reserved/illegal character in directory services like LDAP (which Agile Controller relies on for synchronization). In LDAP syntax, = is used as a structural delimiter in Distinguished Names (e.g., CN=Jack,OU=Users), so its presence in a username breaks the parsing and causes sync to fail.

Why the distractors are wrong:

• A (too long): Names like "Jack" and "Ann" are very short - length is clearly not the issue.
• B (too short): None of the names are unusually short, and Agile Controller doesn't enforce a minimum length that these would violate.
• D (must be numbers and English): The letter portions of the names are valid English characters - the problem is the special character =, not the letters themselves.

Memory tip: Think of = as a "command character" that directory services use internally (like CN=Name). Any username that contains a command character will confuse the system into misreading the data structure - so special characters like =, #, +, ,, ;, <, >, and \ are illegal in usernames for LDAP-based sync.
