CompTIA Network+ (N10-007) — Question 497

Which of the following technologies relies on circuit switching?

Answer options

• A. DMVPN
• B. MPLS
• C. PPPoE
• D. DOCSIS

Correct answer: C

Explanation

PPPoE (Point-to-Point Protocol over Ethernet) is the correct answer as it establishes a dedicated circuit for each session, characteristic of circuit switching. DMVPN, MPLS, and DOCSIS utilize packet switching techniques, where data is sent in packets over shared networks rather than through dedicated circuits.
