Systems Security Certified Practitioner (SSCP) — Question 125

A common way to create fault tolerance with leased lines is to group several T1s together with an inverse multiplexer placed:

Answer options

• A. at one end of the connection.
• B. at both ends of the connection.
• C. somewhere between both end points.
• D. in the middle of the connection.

Correct answer: B

Explanation

The correct answer is B because placing the inverse multiplexer at both ends of the connection ensures that fault tolerance is maintained by managing traffic from both directions. Options A, C, and D do not provide the necessary redundancy and may lead to a single point of failure, compromising fault tolerance.
