1. What is SAP high availability?
Ans:
High availability aims to reduce service interruption by using suitable redundant components and recovery mechanisms. SAP high-availability architecture can involve application servers, databases, enqueue services, and infrastructure components depending on the design.
2. What is disaster recovery in an SAP environment?
Ans:
Disaster recovery provides documented methods for restoring SAP services after a major infrastructure or system failure. It can involve backups, replication, standby systems, recovery procedures, and defined recovery objectives.
3. How do you verify SAP backup jobs?
Ans:
Check backup job status, logs, timestamps, backup destinations, available storage, retention requirements, and error messages. Where applicable, recovery testing should also be performed to confirm that backups are usable.
4. How do you investigate an SAP database alert?
Ans:
Review the alert details, database services, resource utilisation, storage, workload, logs, and recent changes. Determine whether the issue requires BASIS action or coordination with the database administration team.
5. What is SAP Solution Manager used for in technical operations?
Ans:
Depending on the deployed version and landscape, Solution Manager can provide monitoring, diagnostics, technical administration, application lifecycle support, and operational management capabilities.
6. How would you support a large SAP landscape?
Ans:
Use standardised monitoring, documented procedures, controlled change management, incident prioritisation, automation where appropriate, regular health checks, capacity planning, and clear coordination between technical teams.
7. What is SAP software maintenance planning?
Ans:
Maintenance planning involves reviewing supported versions, dependencies, prerequisites, patches, testing requirements, downtime, backups, implementation sequencing, and post-maintenance validation before technical changes are performed.
8. How do you troubleshoot an SAP connectivity issue between systems?
Ans:
Identify the communication method, verify destination and target availability, check network and authentication settings, review gateway or application logs, and test the connection. Escalate infrastructure issues when they fall outside BASIS responsibilities.
9. What is capacity planning for SAP systems?
Ans:
Capacity planning uses historical and projected workload, CPU, memory, database growth, storage, and user activity to estimate future resource requirements and support infrastructure planning.
10. How should a BASIS team prepare for a critical system outage?
Ans:
Follow the incident-management process, assess business impact, preserve technical evidence, involve the appropriate support teams, communicate status, execute approved recovery procedures, validate restored services, and document the incident.
