Designing Cisco Enterprise Networks (ENSLD) — Question 256

A company requires a private WAN design that allows remote sites to connect to HQ. The design must ensure that:

• traffic is always encrypted
• forwarding overhead is reduced
• management of security is centralized
• multicast traffic is supported

Which technology must the company select?

Answer options

Correct answer: D

Explanation

GET VPN is the correct choice as it provides end-to-end encryption for traffic, supports multicast, and allows for centralized key management, which addresses all the company's requirements. IPsec P2P does not support multicast, mGRE lacks centralized management, and DMVPN Phase 3, while efficient, does not handle multicast traffic as effectively as GET VPN.
