A workflow always begins with a trigger.
Explain Stateful vs Stateless Logic Apps.
Answer:
Stateful Workflow
- Stores execution history
- Supports long-running workflows
- Can recover after failures
- Suitable for enterprise integrations
Stateless Workflow
- Faster execution
- No workflow history
- Best for lightweight APIs
- Lower latency
Stateful workflows are preferred for business-critical integrations.
How Do You Handle Exceptions in Logic Apps?
Answer:
Common error handling techniques include:
- Scope Actions
- Configure Run After
- Retry Policies
- Dead Letter Queues
- Parallel Error Handling
- Terminate Actions
Good exception handling ensures workflow reliability.
What Is “Configure Run After”?
Answer:
Configure Run After controls when an action executes based on the previous action’s outcome.
Possible conditions include:
- Success
- Failure
- Timeout
- Skipped
It enables advanced workflow branching and error recovery.
Explain Retry Policies.
Answer:
Retry policies automatically retry failed operations.
Azure supports:
- Fixed Interval
- Exponential Interval
- Custom Retry
Retries help overcome temporary network or service failures.
What Is Azure Integration Account?
Answer:
Integration Account provides B2B capabilities for Logic Apps.
Features include:
- XML validation
- XSLT transformations
- Trading Partner Agreements
- EDIFACT
- X12
- AS2
- Schemas
- Maps
It is essential for enterprise EDI integrations.
How Do You Secure Azure Logic Apps?
Answer:
Security best practices include:
- Managed Identity
- Azure Key Vault
- Private Endpoints
- Azure AD Authentication
- Role-Based Access Control (RBAC)
- Secure Inputs/Outputs
- HTTPS Endpoints
- IP Restrictions
Security should always be considered during workflow design.
What Is Managed Identity?
Answer:
Managed Identity eliminates the need to store credentials inside applications.
Benefits include:
- Automatic credential management
- Secure authentication
- Integration with Azure services
- Reduced security risks
It is considered the recommended authentication method for Azure resources.
Explain Logic Apps Pricing.
Answer:
Pricing depends on deployment type.
Consumption
Charges are based on:
- Workflow executions
- Trigger executions
- Connector usage
Standard
Charges depend on:
- Hosting plan
