The company routinely outsources resources for core activities. An unforeseen risk forces all team members, including outsourced vendors, to work remotely. How can the project manager ensure outsourced vendors continue to deliver?

The correct answer is to develop a new communication and resource management strategy. An unforeseen risk requiring remote work for all, including outsourced vendors, fundamentally changes how the project team operates and interacts. A new strategy is needed to address revised communication channels, resource availability, performance monitoring, and logistical support for remote outsourced personnel to ensure continued delivery. Reviewing the risk management plan is a good initial step, but it's unlikely to contain specific mitigation for an unforeseen risk of this magnitude affecting all resources, especially outsourced ones. Reviewing coordination and communication costs with the supplier is a reactive measure focused on finances, not on ensuring continued delivery. Submitting a change request for the contingency budget might be necessary later if costs increase, but it doesn't proactively address the operational challenge of ensuring vendor performance.
