ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 106

Which two options are valid WAN connectivity methods? (Choose two.)

Answer options

• A. PPP
• B. WAP
• C. DSL
• D. L2TPv3
• E. Ethernet

Correct answer: A, C

Explanation

PPP (Point-to-Point Protocol) and DSL (Digital Subscriber Line) are both recognized methods for establishing WAN connections. WAP (Wireless Access Point) and L2TPv3 (Layer 2 Tunneling Protocol version 3) do not serve as direct connectivity options for WAN, while Ethernet is typically used in local area networks rather than as a WAN connection method.
