Private lines make use of which connection type based on cell switching?

The correct answer is A. ATM. ATM (Asynchronous Transfer Mode) is a cell-switching technology that uses fixed-size 53-byte cells (5-byte header + 48-byte payload) to transport data. Private lines built on ATM provide guaranteed bandwidth and predictable latency, making ATM well-suited for voice, video, and…

Explanation

ATM (Asynchronous Transfer Mode) is a cell-switching technology that uses fixed-size 53-byte cells (5-byte header + 48-byte payload) to transport data. Private lines built on ATM provide guaranteed bandwidth and predictable latency, making ATM well-suited for voice, video, and data. ISP MPLS VPN (B) uses label switching, not cell switching. VTI (C) stands for Virtual Tunnel Interface, a logical construct for VPNs. VPLS (D) is a Layer 2 VPN service using MPLS. Only ATM is specifically defined by its fixed-cell switching architecture.
