CompTIA Network+ (N10-007) — Question 35

Which of the following WAN technologies utilizes the concept of virtual circuits and point-multipoint connections?

Answer options

• A. ISDN
• B. MPLS
• C. PRI
• D. Broadband cable
• E. Frame relay

Correct answer: E

Explanation

Frame relay is the correct answer because it is designed to support virtual circuits, allowing multiple connections over a single link. ISDN, MPLS, PRI, and Broadband cable do not utilize the same virtual circuit and point-multipoint connection paradigm as Frame relay does.
