SIMULATION [Security Architecture] An organization is planning for disaster recovery and continuity ofoperations, and has noted the following relevant findings: 1. A natural disaster may disrupt operations at Site A, which would then cause an evacuation. Users are unable to log into the domain from-their workstations after relocating to Site B. 2. A natural disaster may disrupt operations at Site A, which would then cause the pump room at Site B to become inoperable. 3. A natural disaster may disrupt operations at Site A, which would then cause unreliable internet connectivity at Site B due to route flapping. INSTRUCTIONS Match each relevant finding to the affected host by clicking on the host name and selecting the appropriate number. For findings 1 and 2, select the items that should be replicated to Site B. For finding 3, select the item requiring configuration changes, then select the appropriate corrective action from the drop-down menu.

I agree, for finding 1 it's DNS that needs to be replicated so users can log in at Site B, and for finding 2 it's the pump controls not the physical pumps. For finding 3, fix the VPN concentrator's BGP config to stop route flapping. Makes sense unless I'm missing something?
DNS and pump controls both need to be replicated for site failover, that's key for user auth and infrastructure. For the network instability at Site B, I think modifying BGP on the VPN concentrator is the usual fix for route flapping. Makes sense from a disaster recovery perspective, but open if anyone disagrees.
I don’t think it’s DNS that should be replicated for the login issue, I’d say domain controllers at Site B. That’s usually what lets users log into the domain after a site relocation. Correct me if I’m missing something here, but that’s how we handle it in practice.
