1. What is SAP high-availability architecture?
Ans:
High-availability architecture uses suitable redundant components and recovery mechanisms to reduce service interruption. Depending on the landscape, this may involve application servers, database systems, enqueue services, storage, and infrastructure components.
2. What is the role of backup verification in SAP administration?
Ans:
Backup verification confirms that required backup activities completed successfully and that backup files or systems are available according to operational requirements. Logs, storage destinations, retention, and recovery procedures should be reviewed regularly.
3. How do you investigate an SAP database connection failure?
Ans:
Check database availability, SAP instance status, connection configuration, relevant logs, network connectivity, and database services. The investigation should identify whether the problem originates within SAP, the database, or the underlying infrastructure.
4. What is SAP RFC destination testing?
Ans:
RFC destination testing verifies whether an SAP system can communicate with a configured remote destination. Administrators can review connection, authentication, and authorization-related results to identify integration issues.
5. What is SAP capacity planning?
Ans:
Capacity planning evaluates historical and projected usage of CPU, memory, storage, database resources, users, and workload. The information helps technical teams plan infrastructure resources before capacity becomes a limitation.
6. How do you approach an SAP production incident?
Ans:
Assess the impact, collect technical evidence, identify affected components, follow the incident-management procedure, involve the relevant support teams, implement approved corrective actions, and validate service restoration.
7. What is SAP disaster recovery?
Ans:
Disaster recovery defines procedures and technologies used to restore SAP services after a major failure. It may include backups, replication, standby environments, recovery procedures, and predefined recovery objectives.
8. How do you prepare an SAP upgrade from a BASIS perspective?
Ans:
Review prerequisites, supported versions, system dependencies, custom developments, interfaces, backups, testing plans, downtime requirements, technical steps, and rollback or recovery procedures before implementation.
9. What is the importance of post-upgrade validation?
Ans:
Post-upgrade validation confirms that SAP services, database connectivity, users, jobs, interfaces, transports, applications, and required technical functions are operating correctly after the upgrade.
10. How can a BASIS administrator improve operational efficiency?
Ans:
Efficiency can be improved through standard procedures, proactive monitoring, appropriate automation, accurate documentation, regular health checks, capacity planning, structured incident handling, and consistent change-management practices.
