Which of the following items are included in the billing items of the function workflow Function Graph? (Multiple choice)

Question

Options

• ANumber of function requests
• BFunction execution time
• CNumber of node transitions
• DNode Specifications and Quantity

• A
  81% (29)
• C
  11% (4)
• D
  8% (3)

Explanation

Function Graph (Huawei Cloud's serverless compute service) follows the standard serverless billing model, charging based on how many times functions are invoked (A) and how long each execution runs (B). These two metrics directly reflect the compute resources consumed and are the universally recognized billing dimensions for serverless functions.

Option C (Number of node transitions) is incorrect because node transitions are a billing concept associated with workflow orchestration services like state machines, not with the function execution layer itself. Option D (Node Specifications and Quantity) describes a billing model for container or virtual machine services where you pay for provisioned capacity, which is the opposite of the serverless, pay-per-use model that Function Graph uses.

Memory tip: Serverless billing always follows the "pay for what you use" principle - you are charged only for requests made and time spent executing, never for pre-allocated nodes or transitions between workflow states. If you remember "requests plus runtime equals serverless billing," you can eliminate any answer that implies reserved or infrastructure-based charges.
