Question

Quizplus · Accepted Answer

The technology described in the statement is ATM (Asynchronous Transfer Mode).

Answer: G
 The statement does not provide enough information to determine a specific technology, but metro Ethernet is a common WAN technology that operates at Layer 2 and can reach Layers 1 and 3.

Answer: H
 The statement describes a ring topology WAN, but does not provide information about a specific technology.

Answer: I
 A smart jack is a device used to monitor and troubleshoot WAN connections, but is not a specific WAN technology.

Answer: J
 A transponder is a device used for signal amplification and conversion in telecommunications, but is not a specific WAN technology.

The other options, B (BRI), C (CIR), D (DSLAM), and E (geostationary orbit) are not described or relevant to the information provided in the statement.
