A developer is implementing an RPC call where the client application must wait for a response from the server before it can continue its own processing. Which type of RPC invocation is being used?
Event-driven
Asynchronous
Batched
Synchronous
In a synchronous RPC model, the client application makes a request and is blocked from continuing until the server processes the request and returns a response. This pattern is similar to a local function call. Asynchronous RPC would allow the client to continue processing without waiting for an immediate response. Event-driven architecture is a different integration pattern where services communicate by producing and consuming events. Batched calls refer to grouping multiple requests, which does not inherently define the blocking behavior of the call.
