Qlik Replicate Certification Exam Sample Questions (Q22-Q27):
NEW QUESTION # 22
Which are valid source endpoint types for Qlik Replicate change processing (CDC)? (Select two )
- A. SAP ECC and Extractors
- B. MS Dynamics direct access
- C. Classic Relational RDBMS
- D. Generic REST APIs Data Lake file formats
Answer: A,C
Explanation:
For Qlik Replicate's Change Data Capture (CDC) process, the valid source endpoint types include:
A: Classic Relational RDBMS: These are traditional relational database management systems that support CDC.Qlik Replicate can capture changes from these systems using log-based CDC tools which are integrated to work with most ETL tools1.
C: SAP ECC and Extractors: SAP ECC (ERP Central Component) and its extractors are also supported as source endpoints for CDC in Qlik Replicate.This allows for the replication of data changes from SAP's complex data structures1.
The other options provided are not typically associated with CDC in Qlik Replicate:
B: MS Dynamics direct access: While Qlik Replicate can connect to various data sources, MS Dynamics is not commonly listed as a direct source for CDC.
D: Generic REST APIs Data Lake file formats: REST APIs and Data Lake file formats are not standard sources for CDC as they do not maintain transaction logs, which are essential for CDC to track changes.
For detailed information on setting up source endpoints and enabling CDC, you can refer to the official Qlik documentation and community articles that discuss the prerequisites and configurations needed for various source endpoints2345.
NEW QUESTION # 23
The Qlik Replicate administrator adds a new column to one of the tables in a task What should the administrator do to replicate this change?
- A. Stop and reload the task
- B. Stop task, enable__CT tables, and resume
- C. Change the DDL Handling Policy to accommodate this change
- D. Stop and resume the task
Answer: D
Explanation:
When a new column is added to one of the tables in a Qlik Replicate task, the administrator should stop and then resume the task to replicate this change. This process allows Qlik Replicate to recognize the structural change and apply it accordingly.
The steps involved in this process are:
Stop the task: This ensures that no data changes are missed during the schema change.
Resume the task: Once the task is resumed, Qlik Replicate will pick up the DDL change and apply the new column to the target system.
This procedure is supported by the Qlik Replicate's DDL handling policy, which can be set to perform an
"alter target table" when the source table is altered.This means that when the task is resumed, the new columns from the source tables will be added to the Replicate target1.
It's important to note that while stopping and resuming the task is generally the recommended approach, the exact steps may vary depending on the specific configuration and version of Qlik Replicate being used.
Therefore, it's always best to consult the latest official documentation or support resources to ensure the correct procedure for your environment.
NEW QUESTION # 24
A Qlik Replicate administrator is working on a database where thecolumn names in a source endpoint are too long and exceed the character limit for column names in the target endpoint.
How should the administrator solve this issue?
- A. Open the Windows command line terminal and run the renamecolumn command to update all affected columns of all tables
- B. Define a new Global Transformation rule of the Column type, and follow the prompts to filter and rename all columns in all tables
- C. Visit the Table Settings for each table and select the Filter tab to update all affected columns using a record selection condition
- D. Visit the Table Settings for each table in a task and select the Transform tab to update all affected columns within the Output pane
Answer: B
Explanation:
To address the issue of column names in a source endpoint being too long for the target endpoint's character limit, the Qlik Replicate administrator should:
D: Define a new Global Transformation rule of the Column type: This allows the administrator to create a rule that applies to all affected columns across all tables.By defining a global transformation rule, the administrator can systematically rename all columns that exceed the character limit1.
The process involves:
Going to the Global Transformations section in Qlik Replicate.
Selecting the option to create a new transformation rule of the Column type.
Using the transformation rule to specify the criteria for renaming the columns (e.g., replacing a prefix or suffix or using a pattern).
Applying the rule to ensure that all affected columns are renamed according to the defined criteria.
The other options are not as efficient or appropriate for solving the issue:
A: Open the Windows command line terminal and run the renamecolumn command: This is not a standard method for renaming columns in Qlik Replicate and could lead to errors if not executed correctly.
B: Visit the Table Settings for each table in a task and select the Transform tab: While this could work, it is not as efficient as defining a global transformation rule, especially if there are many tables and columns to update.
C: Visit the Table Settings for each table and select the Filter tab: The Filter tab is used for record selection conditions and not for renaming columns.
For more detailed instructions on how to define and apply global transformation rules in Qlik Replicate, you can refer to the official Qlik documentation onGlobal Transformations.
NEW QUESTION # 25
Which two endpomts have ARC (Attunity Replicate Connect) CDC (Change Data Capture) agents? (Select two )
- A. SAPHANA
- B. Kafka Source
- C. IBM IMS
- D. HP NonStop
- E. IBMDB2Z/OS
Answer: C,D
Explanation:
Questions no:17Verified answer: = A. IBM IMS & E. HP NonStopStep by Step Comprehensive and Detailed Explanation with all References: =ARC (Attunity Replicate Connect) CDC agents are used for capturing changes (CDC) and can be utilized with both relational and non-relational endpoints supported by ARC. The endpoints that have ARC CDC agents include:
IBM IMS (A): This is a database and transaction management system, and it is listed as one of the endpoints supported by ARC CDC agents1.
HP NonStop (E): This is a platform for high-availability servers and is also supported by ARC CDC agents1.
The other options provided do not align with the endpoints that have ARC CDC agents:
B: IBMDB2Z/OS: While DB2 for z/OS is a common database system, it is not mentioned in the context of ARC CDC agents.
C: Kafka Source: Kafka is a streaming platform, and while it can be an endpoint for data, it is not listed as having ARC CDC agents.
D: SAPHANA: SAP HANA is an in-memory database, and it is not specified as having ARC CDC agents.
Therefore, the verified answers areA. IBM IMSandE. HP NonStop, as they are the endpoints that utilize ARC CDC agents for capturing changes1.
NEW QUESTION # 26
When running a task in Qlik Replicate (From Oracle to MS SQL), the following error message appears:
Failed adding supplemental logging for table "Table name" Which must be done to fix this error?
- A. Check the permission of the source endpoint
- B. Enable supplemental logging
- C. Contact the Oracle DBA
- D. Check the permission on the target endpoint
Answer: B
Explanation:
The error message "Failed adding supplemental logging for table" indicates that supplemental logging is not enabled on the Oracle source.
Supplemental logging must be enabled to capture the necessary changes for replication.
To fix this error, you should enable supplemental logging on the Oracle database for the specific table or tables.
This can usually be done by executing the following SQL command on the Oracle source:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
Verify that the logging is enabled and then retry the replication task. This solution aligns with the troubleshooting steps provided in the Qlik Replicate documentation for dealing with supplemental logging errors.
The error message "Failed adding supplemental logging for table 'Table name'" indicates that supplemental logging has not been enabled for the table in the Oracle source database. Supplemental logging is necessary for Qlik Replicate to capture the changes in the Oracle database accurately, especially for Change Data Capture (CDC) operations.
To resolve this error, you should:
Enable supplemental loggingat the database level by executing the following SQL command in the Oracle database:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
This command enables minimal supplemental logging, which is required for Qlik Replicate to function correctly1.
If you need to enable supplemental logging for all columns, you can use the following SQL command:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
This ensures that all necessary column data is logged for replication purposes1.
After enabling supplemental logging, verify that it is active by querying thev$databaseview:
SELECT supplemental_log_data_min FROM v$database;
The correct return value should be 'YES', indicating that supplemental logging is enabled1.
The other options provided are not directly related to the issue of supplemental logging:
A: Contact the Oracle DBA: While contacting the DBA might be helpful, the specific action needed is to enable supplemental logging.
B: Check the permission on the target endpoint: Permissions on the target endpoint are not related to the supplemental logging requirement on the source database.
D: Check the permission of the source endpoint: Permissions on the source endpoint are important, but the error message specifically refers to the need for supplemental logging.
Therefore, the verified answer isC. Enable supplemental logging, as it directly addresses the requirement to fix the error related to supplemental logging in Qlik Replicate21.
