Microservices - Advanced Patterns

AServices automatically switch to choreography mode to recover.

BMicroservices continue independently without any disruption.

CThe entire workflow may halt or become inconsistent due to lost coordination.

DEach microservice retries its last operation until the orchestrator recovers.

Step-by-Step Solution

Solution:

Step 1: Understand orchestrator role
The orchestrator controls the workflow; its failure disrupts coordination.
Step 2: Evaluate options
The entire workflow may halt or become inconsistent due to lost coordination. correctly states the workflow may halt or become inconsistent. Microservices continue independently without any disruption. is false because services depend on the orchestrator. Services automatically switch to choreography mode to recover. is incorrect; no automatic mode switch exists. Each microservice retries its last operation until the orchestrator recovers. is not guaranteed behavior.
Final Answer:
A -> Option C
Quick Check:
