Designing Cisco Enterprise Networks (ENSLD) — Question 52

A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center. An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:
✑ The company uses multicast to deliver training to the stores.
✑ The company uses dynamic routing protocols and has implemented QoS.
✑ To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.
Which solution should be included in this design?

Answer options

• A. VPLS
• B. GET VPN
• C. DMVPN
• D. IPsec

Correct answer: C

Explanation

DMVPN is the correct choice as it allows for dynamic creation of VPN tunnels, which is ideal for the scenario where additional stores are frequently added. It also supports multicast and is compatible with dynamic routing protocols and QoS, making it a perfect fit for the company's needs. The other options, while useful in different contexts, do not provide the same level of dynamic scalability or multicast support as DMVPN.
