C_DBADM_2404 Exam Dumps - SAP Certified Associate Questions and Answers

When renaming a tenant database in the SAP HANA cockpit, the following occurs:

• The tenant database is stopped: Renaming requires that the database be stopped to change its identifier and update related metadata.
• The tenant database is unloaded from memory: To apply the new name and ensure all configurations and metadata are updated, the database must be unloaded from memory.

References=This process is detailed in the SAP HANA administration guide, which outlines the steps and implications of database renaming, including the requirement to stop and unload the database.

Database Administration

To prevent changes to system properties in tenant databases within SAP HANA, you would use theglobal.inifile. This file is used to configure system-wide settings across the entire SAP HANA instance, including tenant databases.global.inihandles the global configuration parameters that affect all databases on the instance, making it the appropriate choice for enforcing settings that block or restrict modifications to system properties.

References=This approach is consistent with SAP HANA administration documentation that specifiesglobal.inias the key file for managing global configuration settings.

When scaling down an SAP HANA Cloud, SAP HANA database instance, the following resources are affected:

• vCPUs: Reducing the number of virtual CPUs will decrease the processing power available to the database instance.
• Memory: Lowering the memory allocation impacts the amount of data that can be stored in-memory, affecting performance and capacity.

References=SAP HANA Cloud service documentation provides details on the impact of scaling operations on database resources, emphasizing the change in compute and memory resources.

Provisioning SAP HANA

In combination with a Lightweight Directory Access Protocol (LDAP) server, SAP HANA supports the following security tasks:A. User group assignment, where user groups defined in LDAP can be mapped to roles in SAP HANA, allowing for group-based access control.D. Role assignment, where SAP HANA roles can be assigned to LDAP groups or individual users based on their LDAP attributes, facilitating centralized role management.LDAP is not directly used for user creation or configuring password policies in SAP HANA, as these aspects are typically managed within the SAP HANA system or the LDAP directory itself.References= SAP HANA Security Guide, which explains integration with LDAP for user and role management.

Database Security

The options for Audited Action Status available in SAP HANA Cloud are:B. Enabled, which indicates that auditing is turned on for the specific action.D. Unsuccessful, which specifically tracks actions that failed due to errors or lack of permissions, helping in pinpointing potential security issues or misconfigurations.Tracking both enabled actions and unsuccessful attempts are crucial for detailed audit trails that support security audits and compliance checks.References= SAP HANA Security documentation detailing audit configuration and audit log management.

Database Security

The SAP HANA hardware and cloud measurement tool (HCMT) is utilized to check and assess certain hardware and system parameters crucial for SAP HANA's optimal performance. With this tool, you can check Linux kernel information (Option A), which is vital as SAP HANA is optimized for specific kernel versions for stability and performance. Additionally, it allows you to perform NUMA (Non-Uniform Memory Access) memory bandwidth tests (Option D), which are critical for understanding how memory is accessed and used by the SAP HANA system. The tool does not, however, provide functionalities to check cloud connector status (Option B) or CPU states (Option C) directly.

Backup and Recovery

When adding a data lake to an SAP HANA Cloud, SAP HANA database, theHDLADMINuser is automatically created. This user is specifically designed for managing and administering the data lake environment within SAP HANA Cloud.

References=SAP HANA Cloud documentation provides information on data lake integration, including details about default users such as HDLADMIN and their roles.

Provisioning SAP HANA

To view the audit trail in the SAP HANA Cloud, you can use:B. The Auditing card in the SAP HANA cockpit, which provides a user interface to access and analyze audit logs directly from the cockpit dashboard.C. The SQL Console in the SAP HANA database explorer, which allows running SQL queries to directly fetch audit data from the audit tables.This dual approach helps in effectively monitoring and ensuring compliance with data access and changes, thereby enhancing the security posture of the organization.References= SAP HANA Cloud documentation and best practices on security monitoring and compliance.

Database Security

To disable tenant database functionalities, you can use:

• Manage Database Configuration: This tool in the SAP HANA Cockpit allows administrators to configure and manage database settings, including the disabling of specific functionalities within a tenant database.
• Manage Restricted Features: Specifically designed to control the availability of certain features within tenant databases, this tool provides a straightforward interface for enabling or disabling functionalities deemed sensitive or unnecessary.

References=These tools are part of the administrative capabilities provided by SAP HANA Cockpit, as documented in SAP HANA administration guides and help portals.

The SAP HANA Hardware and Cloud Measurement Tool (HCMT) is designed to check and measure the performance aspects related to the physical and virtualized resources allocated to SAP HANA. With this tool, you can check CPU states, which involves analyzing the CPU's performance, utilization, and potential bottlenecks. Additionally, the tool allows for a NUMA (Non-Uniform Memory Access) memory bandwidth test, which is crucial for ensuring that memory access patterns are optimized for performance in systems where memory is segmented across different physical machines or nodes.References= SAP HANA administration guides and HCMT documentation.
