Free Practice Questions for SAP C_DBADM_2404 Exam

To initiate a recovery of your SAP HANA Cloud, SAP HANA database instance, you use:

In the SAP HANA cockpit, select the Start Recovery option and set the timestamp: This method provides a user-friendly interface through the SAP HANA cockpit for administrators to precisely control the recovery process, including the selection of specific recovery points based on timestamps.

References=The process for initiating database recovery through the SAP HANA cockpit is detailed in SAP HANA Cloud administration and recovery documentation, which includes step-by-step instructions for performing recoveries.

Backup and Recovery

When upgrading an SAP HANA Cloud, SAP HANA database instance, the possibilities include:A. Upgrade the replica first, which involves applying the upgrade to a secondary replica or system to minimize downtime and risk to the primary system during the upgrade process.B. Select the version to install, providing flexibility in managing the upgrade path and aligning with specific business and system requirements for the version compatibility.Upgrading without restart and reverting to a previous version are not typically supported operations in SAP HANA Cloud, as these actions involve complexities that current technologies and strategies aim to manage differently.References= SAP HANA Cloud administration guide, detailing procedures and options for upgrading database instances within the cloud environment.

SAP HANA Architecture

The scenario that uses the least storage for a 28-day backup cycle would be:

Incremental backup, log backup: Incremental backups store only the changes since the last backup, significantly reducing the amount of storage required compared to full backups.

References=This backup strategy is recommended in SAP HANA backup and recovery guides, which highlight the efficiency of combining incremental backups with log backups to minimize storage use while ensuring data integrity.

Backup and Recovery

To start an SAP HANA Cloud database instance using the command line, the correct command is:

cf update-service <SERVICE_INSTANCE> -c "{ "data": {"service Stopped": false}}"This command utilizes the Cloud Foundry CLI to update the service instance configuration, effectively starting the database if it has been previously stopped.

References=This command and its usage are part of the Cloud Foundry CLI documentation related to managing services in a cloud environment, which is detailed in the SAP Cloud Platform documentation.

Database Administration

In an SAP BTP account, you can provision the following types of SAP HANA Cloud instances:

SAP HANA database: The primary database service provided in SAP HANA Cloud.

Data lake: A scalable storage solution integrated with SAP HANA Cloud, offering large-capacity data management.

References=Provisioning options and service descriptions for SAP HANA Cloud are documented thoroughly in SAP BTP service guidelines, detailing supported instance types such as databases and data lakes.

Provisioning SAP HANA

In the context of provisioning a data lake in SAP HANA Cloud, the default user assigned isHDLADMIN. This user is specifically designed to manage and operate within the data lake environment, providing administrative privileges necessary for managing the data lake's database objects and configurations.

References=The role and capabilities of the HDLADMIN user are typically outlined in SAP HANA Cloud data lake documentation and provisioning guides, which specify default users and their roles within different SAP HANA Cloud scenarios.

Database Administration

To create the COCKPIT MONITOR technical user in SAP HANA 2.0 SPS07, specific privileges are required to ensure the user has appropriate access to system data without compromising security. The correct privileges required are SELECT on the _SYS_TELEMETRY schema (B) and SELECT on the _SYS_STATISTICS schema (D). These privileges enable the technical user to access crucial system performance and monitoring data stored in these schemas, which is vital for effective monitoring and analysis tasks. MONITOR ADMIN (A) is more of a role that encompasses broader administrative privileges, and CATALOG READ (C) provides general access to the catalog objects, which is not specific enough for the creation of a technical user focused on monitoring.References= This determination is derived from the SAP HANA security and user management guidelines, particularly related to the creation and management of technical users within the SAP HANA system.

User Management

To assign users to groups in the SAP HANA cockpit, theCockpit User Administrator roleis required. This role specifically allows for user management capabilities within the cockpit, including grouping users based on roles or responsibilities.

References=The roles and permissions required for different administrative actions in the SAP HANA cockpit are specified in SAP HANA security and administration documentation available on SAP's official help portal.

Provisioning SAP HANA

Within the User Management app of the SAP HANA Cockpit, administrators can assign:

Scopes: These define the range or context in which user permissions apply, often used in administrative tasks to delineate boundaries for user actions within specific areas of the SAP HANA environment.

User groups: Administrators can organize users into groups to manage permissions more efficiently, allowing for bulk assignment of roles and privileges to a collection of users instead of individual user assignments.

References=Details about user management can typically be found in the SAP HANA administration guides and the SAP HANA Cockpit documentation, which outlines user group and scope management.

User Management

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.
