質問 # 13
What is the default single sign-on method when using hdbsql?
- A. Certificate based
- B. Kerberos based
- C. Token based
- D. SAML based
正解：B
解説：
The default single sign-on method when usinghdbsql, the command line interface for SAP HANA, is Kerberos based. This method leverages the Kerberos protocol to authenticate users without transmitting passwords, enhancing the security of connections especially in enterprise environments where Kerberos is commonly used as part of the security infrastructure.References= SAP HANA Administration and Security documentation, which discusses authentication mechanisms supported by SAP HANA including the use of Kerberos for single sign-on.
Database Security
質問 # 14
Which prerequisites must be fulfilled when recovering a tenant database? Note: There are 2 correct answers to this question.
- A. The logon credentials of the <sid>adm user must be available.
- B. The whole system must be shut down before the recovery starts.
- C. The logon credentials of the system database user must be available.
- D. The tenant database must be stopped before the recovery starts.
正解：C、D
解説：
The prerequisites that must be fulfilled when recovering a tenant database include:
* The tenant database must be stopped before the recovery starts: Ensuring the database is not running is crucial to avoid conflicts and data corruption during the recovery process.
* The logon credentials of the system database user must be available: This is necessary because recovery operations often require administrative privileges, and the system database user typically has the required level of access.
References=SAP HANA recovery procedures and prerequisites are thoroughly detailed in the SAP HANA administration guide, which stipulates the necessary conditions and user permissions for successful database recovery operations.
質問 # 15
Which scenarios are supported for a database copy using backup and recovery from a source machine to a target machine? Note: There are 2 correct answers to this question.
- A. The source system release version is higher than the target system.
- B. The source system and target system have different SIDS.
- C. The source system has more nodes than the target system.
- D. The source system and target system have different CPU architecture.
正解：A、B
解説：
The supported scenarios for a database copy using backup and recovery from a source machine to a target machine include:
* The source system and target system have different SIDS: This scenario is supported as it allows the target system to be configured with a different system identifier, which is common during cloning or migration processes.
* The source system release version is higher than the target system: This is feasible provided that the features and data structures used in the higher version are compatible with the target system, allowing for downward compatibility in terms of data recovery.
References=These scenarios are outlined in SAP HANA's technical and administration documentation, which discusses the conditions under which backup and recovery can be effectively utilized across different systems.
Backup and Recovery
質問 # 16
What tools can you use to view the expensive statement trace file? Note: There are 2 correct answers to this question.
- A. SAP BTP cockpit
- B. SAP HANA cockpit
- C. SAP HANA database explorer
- D. SAP HANA Cloud Central
正解：B、C
質問 # 17
In SAP HANA Cloud, which tasks are handled by the cloud provider? Note: There are 3 correct answers to this question.
- A. Tuning the database to run optimally on the underlying operating system and hardware
- B. Backing up the operating system and the database software
- C. Installing, configuring, and upgrading the operating system
- D. Sizing, provisioning, and monitoring the database
- E. Managing users, roles, and permissions in the database
正解：A、B、C
質問 # 18
What do you need in a multitenant database container (MDC) system to run queries across tenant databases?
Note: There are 2 correct answers to this question.
- A. The bidirectional communication channel must be allowed.
- B. The cross-tenant database communication must be explicitly activated.
- C. The user in the source system must be associated with a user in the target database.
- D. The user in the source system must have sufficient privileges in the target database.
正解：B、D
解説：
In a multitenant database container (MDC) system of SAP HANA, to run queries across tenant databases, it is necessary that:A. The user in the source system must have sufficient privileges in the target database.B. The cross-tenant database communication must be explicitly activated.This ensures secure and controlled access across different tenant databases, where each tenant database can be isolated and independently managed.
Activating cross-tenant communication explicitly is a security measure to prevent unauthorized access across tenants.References= SAP HANA Administration Guide and SAP HANA Security Guide which detail user rights management and cross-tenant access configurations.
Database Security
質問 # 19
Which SAP HANA trace must you activate to analyze performance issues with systems where third- party software cannot be installed?
- A. End-to-end
- B. Kernel profiler
- C. SQL
- D. Performance trace
正解：B
解説：
To analyze performance issues in SAP HANA systems, especially in environments where third-party software installations are restricted, activating the Kernel profiler trace is the most effective approach. The Kernel profiler provides detailed insights into the database operations at a low level, capturing performance data about database procedures and commands. This trace is invaluable for understanding the performance characteristics of SAP HANA operations and identifying bottlenecks without the need for additional software layers.References= SAP HANA performance monitoring and tuning documentation.
Monitoring and Troubleshooting

Where does the SAP HANA Cloud, SAP HANA database run in SAP BTP?
- A. Kubernetes container
- B. Kyma runtime
- C. SAP HANA Cloud Central
- D. Cloud Foundry runtime

質問 # 21
Which data stores are activated by default when you provision an SAP HANA Cloud, SAP HANA database? Note: There are 2 correct answers to this question.

質問 # 25
How are savepoints triggered?
Note: There are 2 correct answers to this question.
- A. By performing a database backup
- B. By issuing a transactional commit
- C. By performing a delta merge
- D. By a database soft shutdown
正解：B、D
解説：
Savepoints in SAP HANA are triggered by:B. By issuing a transactional commit, which initiates a savepoint to ensure that all committed transactions are durably written to the disk.C. By a database soft shutdown, during which SAP HANA ensures that all changes are safely written to the disk in the form of a final savepoint to prevent any data loss.Savepoints are not directly triggered by performing a delta merge or a database backup; these processes may coincide with savepoints for consistency but do not inherently cause them.References= SAP HANA administration guide detailing how transactional data management is handled, including the automatic triggering of savepoints at specific operations like shutdowns and commits.
