ChatGPT said:
Sure Deviprasad! Here's a list of 15 probable interview questions (with concise 3–5 line answers) tailored for a SAP CPI/BTP Integration Suite Architect role at a company like Wipro, which often focuses on integration architecture, EDI, API management, and Event Mesh:
🔧 SAP CPI / Integration Suite
-
Q: What are key components of SAP BTP Integration Suite?
A: Integration Suite includes Cloud Integration (CPI), API Management, Open Connectors, Integration Advisor, and Event Mesh. These services allow you to integrate cloud/on-premise systems, manage APIs, and enable event-driven architectures. -
Q: How do you handle error handling in SAP CPI?
A: Use Exception Subprocess, Groovy Scripts, and Alerting mechanisms like email or integration with SAP AIF/SolMan. You can also persist errors to a Data Store or forward to a central error queue. -
Q: What are content modifiers and where do you use them?
A: Content Modifiers are used to add/modify headers, properties, and message body. They're essential for dynamic routing, value mapping, and for setting context in a flow. -
Q: How do you ensure secure communication in SAP CPI?
A: By using HTTPS, OAuth2, client certificates, and encrypted credentials (secure parameter storage). You can also configure integration with IAS/IDP for authentication. -
Q: How do you manage versioning in CPI iFlows?
A: Versioning is handled via the design workspace. You can create revisions, transport via CTS+ or Cloud Transport Management, and maintain history for rollback or audit.
📦 EDI & Integration Advisor
-
Q: What is Integration Advisor and how is it used in EDI?
A: Integration Advisor accelerates mapping design using crowd-sourced intelligence. It helps generate MIGs (Message Implementation Guidelines) and MAGs (Mapping Guidelines) for formats like EDIFACT, X12, IDoc, etc. -
Q: How do you onboard EDI partners in B2B scenarios?
A: Use Trading Partner Management (TPM) to configure partner profiles, define agreements, and map to respective iFlows or Integration Advisor artifacts for automated processing. -
Q: How do you handle version upgrades in EDI mappings?
A: Maintain versioned MIGs and MAGs in Integration Advisor and configure routing logic in TPM to direct messages based on version. Legacy mappings can be preserved using IDoc enhancements.
🌐 API Management
-
Q: How do you secure APIs in SAP API Management?
A: Use OAuth2 policies, API keys, and JWT validations. API proxies can be layered with spike arrest, IP filtering, quota management, and threat protection policies. -
Q: How do you monitor API performance and traffic?
A: Use the API Analytics dashboard in SAP APIM. You can monitor response times, success/failure rates, client IPs, and apply custom logging or SAP Alert Notification integration.
🪢 Event Mesh
-
Q: What is SAP Event Mesh and when do you use it?
A: Event Mesh enables event-driven architecture via asynchronous messaging. It supports decoupling of producers/consumers and is ideal for microservices or EDI event handling. -
Q: How do you integrate Event Mesh with CPI?
A: Use AMQP adapter in CPI to subscribe/publish to Event Mesh queues or topics. Use message headers to handle correlation and maintain reliable delivery.
🔐 General Architecture & Best Practices
-
Q: How do you design scalable integration architecture in BTP?
A: Use modular iFlows, re-usable sub-processes, managed APIs, centralized credential stores, and Event Mesh for decoupling. Consider scaling options via SAP BTP regions and instance limits. -
Q: How do you handle transport and lifecycle management?
A: Use SAP Transport Management (TMS) for artifact movement between DEV-QA-PROD. Maintain CI/CD via SAP CI/CD service or Git-based automation using Web IDE pipelines. -
Q: What’s your strategy for high availability and failover?
A: Deploy redundant BTP instances across regions, use async processing (Event Mesh/Queues), retry mechanisms, and integrate with alert systems to notify on failures.
