質問 # 18
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 system database user must be available.
- B. The logon credentials of the <sid>adm user must be available.
- C. The whole system must be shut down before the recovery starts.
- D. The tenant database must be stopped before the recovery starts.

質問 # 29
You want to change a standard user account into a restricted user account. Which attributes do you need to adjust?
Note: There are 3 correct answers to this question.
- A. Disable ODBC/JDBC Access must be set to "Yes".
- B. Authorization method must be set to "LDAP".
- C. User Group must be set to "Restricted".
- D. Creation of Objects in Own Schema must be set to "No".
- E. PUBLIC role must be set to "No".
正解：A、D、E
解説：
Changing a standard user account to a restricted user account in SAP HANA involves modifying specific attributes to limit the user's capabilities and access within the database:
* Disable ODBC/JDBC Access must be set to "Yes" (A): This prevents the user from connecting to the database using ODBC or JDBC, which are common connectivity methods for external applications and development environments.
* Creation of Objects in Own Schema must be set to "No" (C): Restricted users should not have the privilege to create new objects in their schema, ensuring that their activities are limited to predefined tasks and roles.
* PUBLIC role must be set to "No" (E): Removing the PUBLIC role restricts the user from inheriting any privileges that are generally available to all database users, further limiting their access and capabilities. The options related to Authorization method being set to "LDAP" (B) and User Group must be set to "Restricted" (D) arenot directly related to changing the user account type in SAP HANA but pertain to different aspects of user authentication and group categorization.
References= The conversion between standard and restricted user types is detailed in the SAP HANA security and user administration documentation, highlighting the attribute adjustments necessary for enforcing stricter access controls.
User Management
質問 # 30
What can you assign to a user group in the SAP HANA Cloud, SAP HANA database? Note: There are 2 correct answers to this question.
- A. Password policies
- B. Users
- C. Permissions
- D. Roles
正解：C、D
解説：
In the SAP HANA Cloud, SAP HANA database, user groups can be assigned various entities to manage and control access efficiently. The correct answers are Permissions (C) and Roles (D). Permissions provide detailed control over what specific actions a user group can perform on database objects, applications, or data.
Roles encompass a collection of permissions tailored to facilitate specific job functions or responsibilities, which can be assigned to a user group to streamline authorization management. Assigning Password policies (A) to a user group is not typically done, as password policies are generally set at a system-wide level rather than per group. Assigning individual Users (B) to a user group is a reverse relationship where users are members of groups, not an assignment to the groups themselves.References= This response is based on standard practices for user group management within SAP HANA Cloud as outlined in SAP documentation and security management best practices.

What can you assign to a user with the User Management app in the SAP HANA cockpit? Note: There are 2 correct answers to this question.
- A. User group
- B. LDAP authorization mode
- C. LDAP identity provider
- D. Scopes
正解：A、D
解説：
