Select the statements that apply to the bridge subsystem.

There are two correct answers.

The bridge subsystem runs on the target release version.

The bridge subsystem runs on the source release version.

Users on the bridge access tables via database views.

Only SAP-owned tables can be accessed via the bridge subsystem.

Why is it required that application-defined procedures (AIMs, XPRAs, and XCLAs) are enabled for ZDO?

Choose the correct answer.

Tables accessed by application-defined procedures must be classified manually based on the ZDO enablement.

The ZDO enablement contains meta-data information declaring tables that are accessed by the upgrade subsystem when the ABAP code is executed.

The ZDO enablement of application-defined procedures ensures that none of the tables will become read-only for end-users on the bridge subsystem.

At which point in time of a ZDO project should native database objects stored in SAP HANA Repository 1.0 (_SYS_BIC) be migrated into SAP HANA Deployment Infrastructure (HDI) containers?

Choose the correct answer.

Before the ZDO project is started.

While end-users are already connected to the bridge subsystem.

The adjustment happens as part of the SPDD adjustments in the shadow system.

After the completion of the ZDO project.

The upgrade imports new entries into a customizing table. How would the table be handled and classified by ZDO?

Choose the correct answer.

The table will be shared between the bridge and upgrade subsystems.

The table will be cloned and both the bridge and upgrade subsystem can write into the table.

The table will be cloned and set to read-only for the bridge subsystem.

What are advantages of Silent Data Migration Infrastructure?

There are two correct answers.

Data model changes are fully ZDO compatible.

With ZDO, XPRA programs can be started as silent data migrations.

Data model changes will be performed after the ZDO upgrade.

Affected database tables will not become read-only during a ZDO upgrade.

Which operations modes of SAP Business Warehouse are supported by ZDO?

There are two correct answers.

A short dump occurs in the upgrade subsystem when trying to write into a shared table.

An end-user on the bridge subsystem tries to write into a cloned read-only table.

Software Update Manager evaluates the unallowed table accesses in phase RUN_ZDM_AIM_TRACE_CHECK_SANDBOX.

Unallowed table accesses can be ignored

Which subsystems and system types exist during the ZDO procedure?

There are four correct answers.

Original system

Bridge subsystem

Temporary system

New versions of SAP S/4HANA do not support SAP HANA Repository 1.0 (_SYS_BIC) any longer.
