Supporting Cisco Routing and Switching Network Devices (RSTECH) — Question 14

What are two components of a WAN connection? (Choose two.)

Answer options

• A. CSU/DSU
• B. router
• C. bridge
• D. hub
• E. switch

Correct answer: A, B

Explanation

The CSU/DSU is essential for converting digital data from a router to a format suitable for transmission over a WAN, while a router directs traffic between different networks, making both crucial components of a WAN connection. The other options, such as bridge, hub, and switch, are primarily used in local area networks (LANs) and do not play a direct role in WAN connectivity.
