• Question 76:

  Which actions can you perform on an SAP HANA Cloud, SAP HANA database using the Cloud Foundry CLI? Note: There are 2 correct answers to this question.

  A. Recover instance
  B. Change instance backup schedule
  C. Decrease data volume size
  D. Create instance
  A. Recover instance
  D. Create instance

  ---

  Explanation

  Using the Cloud Foundry CLI, you can perform several administrative tasks on SAP HANA Cloud, SAP HANA database, including:

  Recover instance: Allows administrators to recover a database instance from backups if necessary.

  Create instance: Enables the provisioning of new database instances within the cloud environment.

  Both options are critical for managing the lifecycle and resiliency of database services in the cloud.

  References: The functionality of the Cloud Foundry CLI in relation to SAP HANA Cloud management is covered in SAP Cloud Platform documentation, which details the commands and operations available for database instances.

• Question 77:

  Which storage tier is used to manage rarely changing, persistent data?

  A. Replica
  B. Data lake
  C. Native storage extension
  D. WORM device
  C. Native storage extension

  ---

  Explanation

  The storage tier used to manage rarely changing, persistent data within SAP HANA is the Native Storage Extension (NSE). NSE is designed to:

  Native storage extension (C): Extend the in-memory capabilities of SAP HANA to include disk-based storage, effectively managing larger data volumes that do not fit into memory or do not require the high performance of in-memory processing. NSE allows for cost-effective data management and storage optimization by placing less frequently accessed, non-volatile data on lower-cost, slower disk storage while maintaining seamless access and integration with the in-memory data. This capability supports scenarios where data is infrequently accessed but still needs to be readily available within the SAP HANA environment, without the need for external storage solutions like data lakes (B) or specialized hardware such as WORM devices (D).

  References: SAP HANA documentation on data tiering options provides insights into how NSE works as an integral part of the data management strategy, focusing on cost-efficiency and resource optimization.

• Question 78:

  Which services can you stop in the SAP HANA cockpit from the SYSTEMDB Manage Services app? Note:There are 2 correct answers to this question.

  A. Web dispatcher
  B. Index server
  C. XS engine
  D. Compile server
  A. Web dispatcher
  D. Compile server

  ---

  Explanation

  In the SAP HANA cockpit, from the SYSTEMDB Manage Services app, you can stop the following services:

  Web dispatcher: Manages HTTP traffic to SAP HANA, and stopping this service affects access via web-based applications.

  Compile server: Supports the compilation of SQLScript functions and stored procedures, and can be managed directly from the SYSTEMDB.

  References: Details on managing SAP HANA services through the SAP HANA cockpit are provided in SAP HANA administration guides and official documentation.

• Question 79:

  Which prerequisites must be fulfilled when recovering a tenant database? Note: There are 2 correct answers to this question.

  A. The tenant database must be stopped before the recovery starts.
  B. The logon credentials of the system database user must be available.
  C. The logon credentials of the adm user must be available.
  D. The whole system must be shut down before the recovery starts.
  A. The tenant database must be stopped before the recovery starts.
  B. The logon credentials of the system database user must be available.

  ---

  Explanation

  The prerequisites that must be fulfilled when recovering a tenant database include:

  The tenant database must be stopped before the recovery starts: Ensuring the database is not running is crucial to avoid conflicts and data corruption during the recovery process.

  The logon credentials of the system database user must be available: This is necessary because recovery operations often require administrative privileges, and the system database user typically has the required level of access.

  References: SAP HANA recovery procedures and prerequisites are thoroughly detailed in the SAP HANA administration guide, which stipulates the necessary conditions and user permissions for successful database recovery operations.

• Question 80:

  Which hardware KPIs do you need to size before performing a tailored data center integration (TDI) installation for a productive SAP HANA database system? Note: There are 2 correct answers to this question.

  A. DRAM required for the static data memory area
  B. Total disk space required for the log volume
  C. Persistent memory (PMEM) required for backups
  D. Network bandwidth for the storage zone
  A. DRAM required for the static data memory area
  B. Total disk space required for the log volume

  ---

  Explanation

  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.
