Designing Cisco Enterprise Networks (ENSLD) — Question 140

An engineer must design a VPN solution for a company that has multiple branches connecting to a main office. What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose two.)

Answer options

• A. support for AES 256-bit encryption
• B. greater scalability
• C. support for anycast gateway
• D. lower traffic overhead
• E. dynamic spoke-to-spoke tunnels

Correct answer: B, E

Explanation

The correct answers are B and E because DMVPN provides enhanced scalability, allowing for easy addition of new branches without needing to configure each one individually. Additionally, dynamic spoke-to-spoke tunnels enable direct communication between branches, minimizing the need for traffic to route through the central office. Options A, C, and D are not unique advantages of DMVPN over IPsec tunnels.
