Guys let's use common sense, what solution costs 50 thousand dollars and it will make all devices point to it and if it fails your entire network fails ? think about it just from the logic common sense point of view and then answer. No devices will not lose connectivity if DNA Center goes down.
If you have Cisco SD-Access implemented and DNA Center becomes unreachable then the wired and wireless
network will continue to forward packets as usual. There will be no impact to network performance or behavior.
Yes you will be able to SSH / telnet / console into switches and wireless network infrastructure as usual. For the
period DNA Center is unreachable, Assurance data will be lost, and you will not be able to make configuration
changes to the Cisco SD-Access network
enterprise equipment has separate control plane and data plane and the data plan stays working when the control plane fails. You just can't make any config changes until the control plane is fixed. This works mainly because the control plane is running on CPU while the data plane is using ASICs.
no sure about D , because we don't know whether "user" means just "the already connected users" or both "new" and "already connected users" .
if "user" means both than the answer is BE
if "user" means just "already connected users " than the answer is DE

When Cisco DNA Center loses connectivity to devices in the SD-Access fabric, it can no longer communicate with the controllers that are responsible for managing user access and network policies. This means that new users will be unable to connect to the network, and existing users may experience disruptions in their connectivity.
The existing connected users may not be disconnected but their session may be affected by this loss of connectivity, for example:
They may experience a loss of network services, such as Internet access or access to specific resources.
They may experience a decrease in network performance.
They may be unable to authenticate to the network or access specific resources.
It is important to monitor the health of the Cisco DNA Center and the SD-Access fabric to ensure that connectivity is maintained and to quickly identify and resolve any issues that arise.
