Tricky one. VMware Site Recovery also supports many-to-many or N:N configurations, and other complex multi-site topologies such as a single site A being protected to a recovery site B, while also serving as a recovery site for a third site C. You can use VMware Site Recovery in a shared recovery site configuration in any of the deployment models that vCenter Server supports. https://docs.vmware.com/en/VMware-Site-Recovery/services/com.vmware.srmaas.install_config.doc/GUID-BC46053B-644C-420B-BC68-B71D450711A5.html

The answer is from here: https://docs.vmware.com/en/VMware-Site-Recovery/services/com.vmware.srmaas.install_config.doc/GUID-BC46053B-644C-420B-BC68-B71D450711A5.html

Answer B is in Marketing slides.

B doesn't make sense grammatically since if you peer with other cloud SDDCs you are using multiple, not single. Seems like D.

A supported approach when deploying multiple instances of VMware Site Recovery with VMware Cloud on AWS is to have a single software-defined data center (SDDC) connected to multiple on-premises sites and to other cloud SDDCs. This approach allows an administrator to use a single SDDC as the recovery site for multiple on-premises environments and other cloud SDDCs. This provides a centralized, cloud-based disaster recovery solution that can be managed from the VMware Cloud console. Option A is incorrect because a single SDDC can be paired with multiple remote sites, not just 25. Option C is incorrect because VMware Site Recovery is not an add-on that is deployed in the vSphere Web Client. It is a standalone product that is integrated with VMware Cloud on AWS. Option D is incorrect because while VMware Site Recovery can support multiple protected sites and a shared recovery site, this is not the only supported approach. Therefore, the correct answer is B. A single software-defined data center (SDDC) connected to multiple on-premises sites and to other cloud SDDCs.

Go with B: https://docs.vmware.com/en/VMware-Site-Recovery/services/com.vmware.srmaas.install_config.doc/GUID-BC46053B-644C-420B-BC68-B71D450711A5.html To deploy VMware Site Recovery in a multi-site topology, you deploy Site Recovery Manager Server instances on one or more remote sites, and deploy a corresponding number of VMware Site Recovery instances on the shared VMware Cloud on AWS SDDC.

D is correct, you have multi "protected sites" but 1 "recovery site"

B is correct. Extract from VMC on AWS training course. "You can deploy multiple instances of Site Recovery in a VMware Cloud on AWS SDDC: • Multiple instances support fan-in, fan-out, and other multisite topologies. • You can connect a single VMware Cloud on AWS SDDC to multiple on-premises sites and to other VMware Cloud on AWS SDDCs for disaster recovery purposes. • You can pair up to 10 remote sites with a single SDDC."

Discounting A & B because ‘a single SDDC connected/paired‘ (one-to-many) is not the only supported approach, many-to-many is also supported. Discounting C because the Recovery add-on is deployed in the Cloud Console, not vSphere Client.
