Designing Cisco Enterprise Networks (ENSLD) — Question 264

An enterprise needs to enhance its WAN availability after a recent outage with its only MPLS provider. The proposed solution must have a quick deployment, be affordable, be reliable, and work as a backup for the enterprise's primary MPLS connection. Which solution meets these requirements?

Answer options

• A. Deploy an additional WAN router and use a floating static route.
• B. Contract an internet connection and deploy DMVPN.
• C. Deploy BFD echo mode and probe provider PE.
• D. Contract another MPLS provider and deploy GET VPN.

Correct answer: B

Explanation

The correct answer is B because contracting an internet connection and deploying DMVPN allows for a quick and cost-effective backup solution that can provide reliable connectivity. Option A, while useful, does not provide the same level of redundancy as DMVPN over an internet connection. Option C focuses on probing the provider but does not address the backup need, and option D requires a more complex and potentially expensive setup with another MPLS provider.
