Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 482

A company is looking to implement VPN between their Head Quarter and over 100+ Branch Offices. They are looking for a solution that:
1. Reduces deployment complexity
2. Simplifies branch communications
3. Offers branch to branch connectivity.
4. Is cost effective
5. Offers strong encryption

Select the best option from the below options that you would recommend to implement.

Answer options

Correct answer: C

Explanation

DMVPN (Dynamic Multipoint Virtual Private Network) is the best choice as it supports dynamic connections between multiple sites, simplifying branch communications and reducing deployment complexity. MPLS is more expensive and complex for such a large number of branch offices, while IPSEC typically does not provide the same level of ease for multiple branch connections. GRE does not offer encryption by itself, making it less secure compared to DMVPN.
