A global organization's Chief Information Security Officer (CISO) has been asked to analyze the risks involved in a plan to move the organization's current MPLS-based WAN network to use commodity internet and SD-WAN hardware. The SD-WAN provider is currently highly regarded but is a regional provider. Which of the following is MOST likely identified as a potential risk by the CISO?
The primary concern when a global organization transitions from a traditional MPLS-based WAN to a regional SD-WAN provider is whether the provider can support the organization's requirements effectively. Given that the SD-WAN provider is regional, the potential risk lies in their ability to provide adequate troubleshooting and maintenance support for a global operation. As the organization spans multiple regions, the regional provider may lack the infrastructure, resources, and expertise necessary to manage a global network's complexities and maintain seamless operations.
C. "Traditional MPLS network operations centers are known for their focus and troubleshooting ability, providing end-to-end management of both the WAN edge and circuit. Generally, ISPs aren't as focused, which means the onus is on the vendor to troubleshoot and manage connectivity issues." https://www.techtarget.com/searchnetworking/tip/5-common-SD-WAN-challenges-and-how-to-prepare-for-them
C. The SD-WAN provider may not be able to support the required troubleshooting and maintenance. Since the SD-WAN provider is a regional provider and the organization is global, the CISO may identify the risk that the provider might not be able to support the required troubleshooting and maintenance for the organization's entire WAN infrastructure. This concern arises from the possibility that the provider may not have the necessary resources or expertise to support a global organization's diverse locations and requirements.
C. The SD-WAN provider may not be able to support the required troubleshooting and maintenance.
I want to say it is D. Makes the most sense being cloud based.
As a regional provider, there could be limitations in their ability to provide 24/7 support, global coverage, or quick resolution times, which are crucial for a global organization
