Which of the following is a challenge with Azure Virtual WAN as a platform?

The challenge with Azure Virtual WAN as a platform is that it does not inherently provide a multi-cloud architecture. Azure Virtual WAN is primarily designed to facilitate secure, optimized, and scalable network connectivity across different branches and services within the Azure ecosystem. While it focuses on connecting Azure resources and optimizing the user experience, it has limitations when it comes to integrating with other cloud providers in a seamless manner.

This limitation means that organizations seeking to implement a multi-cloud architecture may find it challenging to do so if they rely exclusively on Azure Virtual WAN, as it does not have built-in features or support for connecting directly with other cloud environments like AWS or Google Cloud Platform. As a result, those looking for multi-cloud capabilities would need to explore additional strategies or tools to bridge those gaps.

Other options may touch on aspects of Azure Virtual WAN, but the primary focus here is on the architecture aspect and its lack of flexibility in multi-cloud environments, making option B the focal point of the challenge.
