C_TADM_23 Practice Exam Questions with Answers SAP Certified Technology Consultant – SAP S/4HANA System Administration Certification

In SAP HANA, tenant database functionalities can be managed and restricted through various administrative tools and applications. The 'Manage Restricted Features' app (A) allows administrators to control and restrict specific features or functionalities at the database level, ensuring compliance and security as per the organizational policies. Similarly, the 'Manage Database Configuration' app (D) provides a comprehensive interface for system database administrators to adjust and manage database configurations, including the enabling or disabling of functionalities for tenant databases. These tools offer a high level of granularity and control, making it possible to tailor the database environment to meet specific requirements or constraints. The 'hdblcm' tool (B) and 'hdbuserstore' tool (C) serve different purposes and are not directly used for disabling tenant database functionalities.

The HTTPURLLOC table in SAP S/4HANA is used to configure the mapping of logical URLs to physical URLs. This functionality is particularly useful in scenarios where you need to redirect or define specific URLs within the SAP system for various purposes.

• A. The hostname of the URL launched by transaction /UI2/FLP:By maintaining entries in the HTTPURLLOC table, administrators can specify the hostname for URLs that are launched by specific transactions, such as the SAP Fiori Launchpad (/UI2/FLP). This allows for the customization of the URLs used by the Fiori Launchpad, enabling it to point to specific hosts or paths as required by the organization's infrastructure or security policies.

This configuration is essential for ensuring that the SAP Fiori Launchpad can access the necessary resources and services, especially in complex network environments or when integrating with external web services.

In an AS ABAP-based SAP system, the lock table plays a crucial role in managing data consistency by preventing simultaneous write access to the same data by different transactions. The lock table is stored in:

• D. Main memory of the host of the Central Services instance:The Central Services instance of an SAP system includes services like the Message Server and Enqueue Server. The lock table, managed by the Enqueue Server, resides in the main memory of the host running the Central Services instance. This placement is strategic because it allows for fast access to lock information, minimizing latency and ensuring that locks can be quickly granted and released. Storing the lock table in memory rather than on disk or in the database ensures high-performance lock management, which is critical for maintaining the system's overall responsiveness and stability.

This architecture underscores the importance of efficient lock management in ensuring data integrity and system reliability, particularly in environments with high transaction volumes.

In an SAP HANA database running in log mode "normal," regular log backups are automatically executed under specific circumstances. One such circumstance is when the log segment is full (D), necessitating a backup to free up space for new log entries. Additionally, a regular log backup is triggered when a predefined time threshold is exceeded (C), ensuring that log backups occur at regular intervals even if the log segment isn't full. This mechanism helps in maintaining a balance between performance and data safety, ensuring that log data is preserved for database recovery without overwhelming the system's storage with frequent backups.

ABAP SQL and native SQL are two methods of executing SQL statements within ABAP programs in SAP systems. ABAP SQL, also known as Open SQL, offers certain features not available with native SQL:

• B. Database independence:ABAP SQL provides a level of abstraction from the underlying database system, allowing developers to write database-agnostic code. This means that the same ABAP SQL code can run on any database supported by SAP, such as SAP HANA, Oracle, or Microsoft SQL Server, without modification. This database independence simplifies code maintenance and enhances portability across different SAP system environments.
• D. Use of the AS ABAP data buffer:ABAP SQL leverages the application server's data buffering capabilities, which can significantly improve performance by reducing database access. When data is read using ABAP SQL, it can be retrieved from the buffer if it has been accessed recently, instead of making a round trip to the database. This feature is particularly beneficial for frequently accessed, read-intensive data, contributing to reduced database load and faster data retrieval.

These features underscore the advantages of using ABAP SQL for database operations within ABAP programs, offering enhanced portability, performance, and ease of use in a multi-database SAP landscape.

In an SAP system, instances that have processes establishing a connection to the database include the Additional Application Server (B) and the Primary Application Server (C). Both these instances host application server processes that directly interact with the database to fetch, store, and manipulate data as part of the SAP system's operations. The Central Services (A) instance primarily provides services like message passing and enqueue handling, and the Enqueue Replication Server (D) is involved in lock management replication in high-availability scenarios, neither of which directly establish database connections as part of their primary functions.
