SAP Updated C_DBADM_2404 Exam Questions and Answers by ariya

During a standard SAP HANA database system installation, the following users are created or validated:

• SYSTEM: The default superuser for SAP HANA with full administrative rights.
• SAP: Represents a database user associated with the SAP system identifier, typically used for SAP application-specific tasks.
• sapadm: This operating system user is created to manage SAP HANA at the OS level.

References=The creation and validation of these users are standard procedures in SAP HANA installations, as outlined in SAP HANA installation and security documentation.

Backup and Recovery

For a tailored data center integration (TDI) installation of a productive SAP HANA database system, it is essential to size the following hardware KPIs:A. DRAM required for the static data memory area, as it determines the amount of main memory needed to hold the active dataset of the SAP HANA database in memory for fast processing.B. Total disk space required for the log volume, which is crucial for maintaining the log entries that record all transactions and database changes, necessary for recovery and durability.Persistent memory (PMEM) for backups and network bandwidth for the storage zone, while important in their own right, are not directly related to initial sizing criteria for DRAM and disk space as per SAP HANA TDI guidelines.References= SAP HANA Tailored Datacenter Integration (TDI) guide which includes details on sizing and planning infrastructure for deploying SAP HANA.

SAP HANA Architecture

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

SAP HANA supports the following cryptographic libraries:A. CommonCryptoLib, which is SAP’s own cryptographic library, tailored specifically for integration with SAP HANA and optimized for performance on SAP hardware.C. OpenSSL, a widely used library that supports a variety of cryptographic operations necessary for secure communications and data protection within SAP HANA environments.Libgcrypt and LibreSSL are not standard cryptographic libraries supported or recommended for use within SAP HANA environments, as they do not align with the tailored optimizations and integrations provided by SAP’s own cryptographic solutions or the widely adopted OpenSSL.References= SAP HANA security documentation that outlines supported cryptographic solutions for securing data at rest and in transit.
