CCDE: Cisco Certified Design Expert (Practical) — Question 24

Company XYZ has 30 sites running a legacy private WAN architecture that connects to the Internet via multiple high-speed connections. The company is now redesigning their network and must comply with these design requirements:
* Use a private WAN strategy that allows the sites to connect to each other directly and caters for future expansion
* Use the Internet as the underlay for the private WAN
* Securely transfer the corporate data over the private WAN
Which two technologies should be incorporated into the design of this network? (Choose two.)

Answer options

• A. PPTP
• B. DMVPN
• C. IPsec
• D. GET VPN
• E. S-VTI

Correct answer: B, C

Explanation

The correct answers, DMVPN and IPsec, are suitable for establishing a scalable private WAN over the Internet, allowing for direct communication between sites while ensuring data security. PPTP is outdated and not suitable for modern security needs, while GET VPN and S-VTI do not provide the same flexibility and scalability as DMVPN in this scenario.
