Explaining application network basics7% of the exam
Web API Contracts and Characteristics
Identify the network contract a web API exposes, choose interactions by resource intent, and distinguish each transport boundary from the implementation behind it.
Describe the role and characteristics of web APIs.
~5 min read · 4 practice questions
What the exam expects
- Distinguish a local software interface from a network-accessible service.
- Explain how consumers use a documented interface across implementation languages.
- Match HTTP operations to resource intent.
- Trace transport protection across the connections involved in an API call.
An API defines software interactions; a web service exposes interactions over a network; a resource is an addressable subject of an HTTP interaction; a TLS context configures transport security. These terms describe different parts of the contract and communication path (APIs and web services, HTTPS proxies).
Key facts
Language boundary
- Detail
- Compatible network messages allow different implementation languages.
Local interface
- Detail
- A library API is not automatically a remote service.
Retrieval
- Detail
- GET requests resource information.
Proxy transport
- Detail
- Inbound and outbound connections have separate TLS configuration.
Secret preparation
- Detail
- Enable Secret Group Downloadable and target the TLS context to Mule.
Configuration access
- Detail
- Read secrets metadata and Manage API Configuration address different permissions.
- Why should a proxy engineer check secret-metadata access separately from API configuration access?
- When preparing the secret group for this workflow, which setting must be enabled?
- Which target should the prepared TLS context use for the Mule proxy?
