質問 # 17
In the SAP Commerce cache, how does invalidation work on a product type?Note: There are 2 correct answers to this question.
- A. All cached FlexibleSearch results where Product type is included are invalidated because the result set might have changed.
- B. Cached Product items updated during the import are invalidated only in the node where the import is running.
- C. All cached FlexibleSearch results are invalidated from the query results region because the result set might have changed.
- D. Cached Product items updated during the import are invalidated in all connected SAP Commerce cluster nodes and are reloaded from the database when it is used next.
正解：A、D
解説：
In the SAP Commerce cache, invalidation works on a product type by invalidating cached Product items updated during the import in all connected SAP Commerce cluster nodes and by invalidating all cached FlexibleSearch results where Product type is included. This ensures that the cache only holds valid data and that the queries return consistent results. The invalidation is not limited to the node where the import is running, nor does it affect all cached FlexibleSearch results from the query results region. Reference: 1

質問 # 28
Which ImpEx headers can you use to update an SAP Commerce Cloud item?Note: There are 2 correct answers to this question.
- A. INSERT_UPDATE UserGroup;UID[unique=true];locname[lang:en];locname[lang:de];groups(uid)[mode=append]
- B. INSERT_UPDATE UserGroup;UID[unique=true];locname[lang=en];locname[lang=de];groups(uid)[mode=append]
- C. INSERT_UPDATE UserGroup;UID;locname;groups(uid)[mode=append]
- D. UPDATE UserGroup;UID[unique=true];locname;groups(uid)[mode=append]
正解：B、D
解説：
The ImpEx headers that you can use to update an SAP Commerce Cloud item are INSERT_UPDATE UserGroup;UID[unique=true];locname[lang=en];locname[lang=de];groups(uid)[mode=append] and UPDATE UserGroup;UID[unique=true];locname;groups(uid)[mode=append]. These headers can modify existing items or create new items if they do not exist. The INSERT_UPDATE header can also specify the language for localized attributes using the lang modifier. The other headers are not valid because they either use an incorrect syntax for the lang modifier (B) or do not specify the unique attribute (D).
質問 # 29
What happens when you set the impex.legacy.mode property to True?Note: There are 2 correct answers to this question.
- A. The INSERT, UPDATE, and REMOVE operations are performed by the ModelService during the import.
- B. The INSERT, UPDATE, and REMOVE operations are NOT performed by the ModelService during the import.
- C. The ServiceLayer interceptors and validators are triggered during the import/export process.
- D. The ServiceLayer interceptors and validators are NOT triggered during the import/export process.
正解：B、D
解説：
When you set the impex.legacy.mode property to True, you enable the legacy mode of ImpEx, which means that the ServiceLayer interceptors and validators are not triggered during the import/export process and that the INSERT, UPDATE, and REMOVE operations are not performed by the ModelService during the import. The legacy mode is a quick and crude way of importing data that bypasses the ServiceLayer of SAP Commerce. It may improve performance but also increase the risk of data inconsistency or errors.

質問 # 30
A customer reports an error and provides the following snippet of a log file:INFO | jvm 1 | srvmain
| 2013/11/15 21:36:38.829 | ERROR [ImpExWorker<1/4>] (000000RS-ImpEx-Import) [MultiThreadedImpExImportReader] line 11 at main script: worker 1 got error com.microsoft.sqlserver.jdbc.SQLServerException: Violation of PRIMARY KEY constraint
'PK 3819157796645776366'. Cannot insert duplicate key in object 'dbo.users'. The duplicate key value is (8796126019588).INFO | jvm 1 | srvmain | 2013/11/15 21:36:38.876 | de.hybris.platform.jalo.JaloSystemException: com.microsoft.sqlserver.jdbc.SQLServerException: Violation of PRIMARY KEY constraint 'PK 3819157796645776366'. Cannot insert duplicate key in object 'dbo.users'. The duplicate key value is (8796126019588).[HY--1]What could be the root cause of the error?Note: There are 2 correct answers to this question.
- A. The current PK sequence value is corrupt.
- B. SAP Commerce verifies that the key is NOT unique and reports an exception.
- C. The database engine verifies that the key is NOT unique and reports an exception
- D. A primary key is used in the database instead of a unique index.
正解：B、C
解説：
The root cause of the error is that the database engine verifies that the key is not unique and reports an exception. This happens when an attempt is made to insert a duplicate primary key value in the users table. SAP Commerce also verifies that the key is not unique and reports an exception. The current PK sequence value is not corrupt, nor is a primary key used instead of a unique index.

- B. Add a new bean definition with a new ID for the new service.
- C. Modify the existing bean definition with the new service.
- D. Replace all injections with a new ID for the new service.
- E. Implement a new custom service by extending the existing service.
正解：A、B、E
解説：
The steps that you must do when you provide a workaround for a code glitch in an existing service, such as ProductService, are adding a new bean definition with a new ID for the new service, implementing a new custom service by extending the existing service, and overriding the alias of the original bean definition. These steps can help you create a custom service that overrides the default behavior of an existing service without modifying its source code. You do not modify the existing bean definition with the new service, nor do you replace all injections with a new ID for the new service, as these steps may cause errors or inconsistencies.
