Qlik Replicate Certification QREP Exam Questions

Answer : A, E

The SOURCE_UNLOAD component is responsible for reading data from the source endpoint.

The TARGET_LOAD component is responsible for writing the data to the target endpoint.

These components work in tandem during the Full Load replication process to move data from the source to the target. According to Qlik Replicate documentation, these two components are crucial in handling the extraction and loading phases of Full Load replication.

In the context of Full Load replication with Qlik Replicate, the components responsible for reading data from the source and writing it to the target are:

SOURCE_UNLOAD: This component is responsible for unloading data from the source endpoint. It extracts the data that needs to be replicated to the target system1.

TARGET_LOAD: This component is in charge of loading the data into the target endpoint. After the data is extracted by the SOURCE_UNLOAD, the TARGET_LOAD component ensures that the data is properly inserted into the target system1.

The other options provided do not align with the Full Load replication process:

B . TARGET_APPLY and D. SOURCE_CAPTURE are typically associated with the Change Data Capture (CDC) process, not the Full Load process2.

C . TARGET_UNLOAD is not a recognized component in the context of Qlik Replicate's Full Load replication.

Therefore, the correct answers are A. SOURCE_UNLOAD and E. TARGET_LOAD, as they are the components that handle the reading and writing of data during the Full Load replication process12.

Answer : D

In the Qlik Enterprise Manager Analytics GUI, users can view messages related to both server and task trends. This includes:

Server-specific trends: These are metrics and trends related to the performance and usage of the servers, such as memory consumption and disk usage1.

Task-specific trends: These include metrics and trends specific to individual tasks, such as the number of tables and records processed, throughput, and the number of changes applied1.

Therefore, the correct answer is D. Server and task trends, as the Analytics tab in Qlik Enterprise Manager allows users to review trends over a specific time period for both servers and tasks. Users can filter the data to show information for a particular timeframe and for particular tasks, Replicate servers, source databases, and target databases2.

For more detailed information on the types of messages and trends that can be viewed in the Qlik Enterprise Manager Analytics GUI, you can refer to the official Qlik documentation on Analytics dashboards and Analytics.

Answer : C

In a scenario where an operative database can commit only two engines to Qlik Replicate for initial loads, the task settings should be modified to ensure that no more than two tables are loaded at any given time. This can be achieved by:

C . Apply Full Load Settings to limit the number of engines to two: This setting allows you to specify the maximum number of concurrent table loads during the Full Load operation. By limiting this number to two, you ensure that the operative database's capacity is not exceeded1.

The other options are not suitable because:

A . Apply Change Processing Tuning: This option is related to the CDC (Change Data Capture) phase and not the initial Full Load phase. Increasing the apply batched changes interval would not limit the number of engines used during the Full Load.

B . Qlik Replicate tasks only load one table at a time by default: This statement is not accurate as Qlik Replicate can be configured to load multiple tables concurrently, depending on the task settings.

D . Apply Full Load Tuning to read a maximum number of tables not greater than two: While this option seems similar to the correct answer, it is not a recognized setting in Qlik Replicate's configuration options.

For detailed guidance on configuring task settings in Qlik Replicate, particularly for managing the number of concurrent loads, you can refer to the official Qlik community articles on Qlik Replicate Task Configuration Options.

Answer : C

To identify the internal commands that Qlik Replicate is executing prior to an error, the Trace logging level should be used. This level provides detailed information about the operations being performed by Qlik Replicate, including the internal commands executed before an error occurs1.

Here's how the Trace logging level works in Qlik Replicate:

When logging is set to Trace, the log lines are identified with ]T:. This indicates that the log will include detailed trace information about the internal workings of Qlik Replicate, such as sending control records to components or waiting for termination of threads1.

The Trace level is more detailed than Warnings (]W:) and Errors (]E:), which only show warning and error messages without the detailed context of the operations leading up to them1.

The Trace level is also distinct from Verbose (]V:), which provides even more detailed logging information but may not be necessary for identifying the commands leading up to an error1.

Therefore, the correct answer is C. Trace, as it is the appropriate logging level to use when you need to analyze the actions performed by Qlik Replicate just before an error occurs1.

Answer : A

To download the task diagnostic package in Qlik Replicate, you need to follow these steps:

Open the task from the overview in the Qlik Replicate Console.

Switch to the Monitor view.

Click on the Tools toolbar button.

Navigate to Support.

Select Download Diagnostic Package1.

This process will generate a task-specific diagnostics package that contains the task log files and various debugging data that may assist in troubleshooting task-related issues. Depending on your browser settings, the file will either be automatically downloaded to your designated download folder, or you will be prompted to download it. The file will be named in the format <task_name>__diagnostics__<timestamp>.zip12.

The other options provided do not accurately describe the process for downloading a diagnostic package in Qlik Replicate:

B is incomplete and does not provide a valid path.

C incorrectly suggests going to server settings and logging, which is not the correct procedure.

D suggests a method that is not documented in the official Qlik Replicate help resources.

Therefore, the verified answer is A, as it correctly outlines the steps to download a diagnostic package in Qlik Replicate12.

Answer : D

The server logs in Qlik Replicate provide information about the Qlik Replicate Server instance, rather than individual tasks. The logs can include various levels of information, such as errors, warnings, info, trace, and verbose details1. Specifically, the server logs can provide insights into:

Network and performance issues: These might be indicated by error or warning messages related to connectivity or performance bottlenecks.

Load status and performance of task: While the server logs focus on the server instance, they may contain information about the overall load status and performance, especially if there are server-level issues affecting tasks.

Specific task information: The server logs can include information about tasks, particularly if there are errors or warnings that pertain to task execution at the server level.

Qlik Replicate Server status: This includes general information about the server's health, status, and any significant events that affect the server's operation.

Therefore, while the server logs can potentially contain a range of information, the primary purpose is to provide details on the Qlik Replicate Server status (D), including any issues that may impact the server's ability to function properly and manage tasks231.

Answer : C

If a task has missing metadata, you need to first stop the task.

Navigate to the 'Advanced Run' options.

Select the option 'Metadata Only.'

Start the task with this setting to process the missing metadata.

Stop the task again after the metadata is added.

Resume normal task processing. This procedure ensures that only the metadata is processed without affecting the existing data on the target side. This method is recommended in Qlik Replicate documentation for handling missing metadata issues.

To add missing metadata in a Qlik Replicate task after the task has been stopped, the correct approach is to use the Advanced Run option for metadata only. Here's the process:

Select the task that requires metadata to be added.

Go to the Advanced Run options for the task.

Choose the Metadata Only option, which has two sub-options:

Recreate all tables and then stop: This will rebuild metadata for all available tables in the task.

Create missing tables and then stop: This will rebuild metadata only for the missing tables or the tables that were newly added to the task1.

By selecting the Metadata Only option and choosing to create missing tables, you can ensure that the metadata for the newly added tables is updated without affecting the existing tables and data. After this operation, you can stop the task again and then resume processing.

The other options provided are not the recommended methods for adding missing metadata:

A and D suggest dropping tables or data, which is not necessary for simply adding metadata.

B suggests reloading the target, which is not the same as updating metadata only.

Therefore, the verified answer is C, as it accurately describes the process of adding missing metadata to a Qlik Replicate task using the Advanced Run options1.
