Which of the following statements about Password-based Call Restriction Service is CORRECT?

Question

Options

• AThe default service password is 123456.
• BAll users dial the call restriction prefix, enter the password and place a call.
• CUsers with this service enabled should dial the call restriction prefix, enter the password before
• DUsers without this service cannot place any call.

• A
  75% (21)
• B
  4% (1)
• C
  14% (4)
• D
  7% (2)

Explanation

Option A is correct because Password-based Call Restriction Service is configured with a factory default password of 123456, which administrators are expected to change upon setup - a common default in telecom systems.

Why the distractors are wrong:

• B is incorrect because not all users dial the restriction prefix - only those with the service enabled need to authenticate before calling.
• C is partially correct in wording but is incomplete as written (the sentence is cut off), making it an unreliable choice; the key distinction is that only users with the service enabled follow this flow.
• D is incorrect because users without this service are unaffected - they place calls normally without any password requirement. The restriction applies to enrolled users, not to those outside the service.

Memory tip: Think of it like a Wi-Fi router - it ships with a default password (123456 here) that you're supposed to change. Only devices configured to use the restriction need the password; everyone else connects freely.
