SK0-004 · Question #3
When attempting to diagnose service access issues between multiple hosts that coordinate information, which of the following can be used to track dependencies?
The correct answer is A. Dataflow diagrams. Dataflow diagrams map how data moves between services and hosts, making them ideal for identifying dependencies and tracing service access issues.

Why each option
Dataflow diagrams map how data moves between services and hosts, making them ideal for identifying dependencies and tracing service access issues.
Dataflow diagrams explicitly show how information flows between components, processes, and systems, allowing an administrator to trace which services depend on which hosts and quickly identify where a dependency is causing an access failure.
Architecture diagrams show the structural layout of systems but do not detail the directional flow of data or service-to-service dependencies at a granular level.
Baseline documentation records normal performance metrics over time and is used for anomaly detection, not for mapping service dependencies.
Service manuals provide operational and maintenance instructions for individual services or hardware, not cross-service dependency relationships.
