In a UML activity diagram, which symbol represents a task?

AA round-cornered rectangular box

BA filled in circle

CA diamond shaped box

DA bullseye

Show Suggested Answer

Suggested Answer: A

In a UML (Unified Modeling Language) Activity Diagram, the symbol used to represent a task (or action/activity) is a round-cornered rectangular box. This shape denotes an individual piece of work or step carried out within the process.

The other symbols represent:

A filled in circle (B): The Initial Node (start of the process).

A diamond shaped box (C): A Decision or Merge Node (a point where a choice is made or paths recombine).

A bullseye (D) (a filled circle inside an outer circle): The Activity Final Node (end of the process flow).

C) a diamond shaped box is for decisions, not tasks. Definitely A).

I’m not sure, but B) a filled in circle seems too simple for a task.

I thought a task was represented by a diamond. Guess I need to brush up on my UML.

I’m confused about the bullseye option; I don’t recall seeing that in any of the diagrams we studied.

I feel like the diamond shape is for decisions, so that can't be it. I’m leaning towards A.

I remember practicing a question like this, and I think the filled circle is for the start of the process, not a task.

I'm drawing a blank on this one. Is the task symbol the bullseye? Or wait, maybe it's the filled in circle? I need to review my notes.

The task symbol is the round-cornered rectangular box, right? I'm pretty sure that's what we covered in the activity diagram section.
