What is the difference between Dual-Site and Dual-Room?

Question

Options

• ADual-Room is a kind of Dual-Site deployment within the same building
• BDual-Room is Active / Standby and Dual-Site is Active / Active
• CDual-Room is a Single-Site deployment where all Appliances are connected to both orchestrators
• DThey are the same

• B

Explanation

Option A is correct because Dual-Room applies the same redundancy principle as Dual-Site - two separate physical locations - but constrains both locations to rooms within the same building. It is essentially a "same-building" variant of Dual-Site, not an entirely different concept.

B is wrong because Active/Active vs. Active/Standby describes the operational mode of a deployment, not its physical topology. Either Dual-Site or Dual-Room can potentially run in either mode - topology and failover behavior are separate concerns.

C is wrong because Dual-Room is not a Single-Site deployment. Single-Site means all appliances share one location; Dual-Room explicitly requires two distinct physical rooms, maintaining geographic separation within the building.

D is wrong because the physical scope differs meaningfully: Dual-Site spans separate buildings or data centers (potentially across cities), while Dual-Room is bounded to two rooms in one building - this affects latency, failure domain, and disaster recovery planning.

Memory tip: Think of it as a nesting hierarchy - Dual-Room ⊂ Dual-Site. Dual-Room is just Dual-Site with the smallest possible physical distance between the two "sites." If the two locations share a roof, it's Dual-Room; if they don't, it's Dual-Site.
