Curious about Actual Qlik Data Integration (QREP) Exam Questions?

Correct : A

When the connection to the source endpoint is unavailable for an extended period, and the log files are limited to only 2 hours of data before being deleted, the safest way to ensure a consistent state in the target endpoint is to use the Reload Target Run option (A). This approach is recommended because it allows for a complete refresh of the target data, ensuring that it is in sync with the source once the connection is re-established.

The Reload Target Run option is designed to handle situations where the replication logs are not sufficient to recover the replicated state due to extended outages or log retention policies. By reloading the target, you can be confident that the data reflects the current state of the source, without relying on potentially incomplete change logs.

Starting processing from a fixed date and time (B) or recovering from a locally stored checkpoint would not be reliable if the logs do not cover the entire period of the outage. Resuming the task and ignoring warnings (D) could lead to inconsistencies due to missed changes.

Therefore, the Reload Target Run option is the safest method to create a consistent state in the target endpoint under these circumstances1.

Correct : C

Qlik Enterprise Manager supports a range of open API methods that allow for programmatic interaction with the system. The supported API methods are:

REST SDK: This provides a RESTful interface for interacting with Qlik Enterprise Manager, allowing for operations such as viewing task details, running tasks, and exporting or importing task definitions12.

.NET SDK: The .NET SDK enables developers to use .NET languages to interact with Qlik Enterprise Manager, facilitating integration with other .NET applications3.

Python SDK: The Python SDK allows for scripting and automation of tasks in Qlik Enterprise Manager using Python, which is particularly useful for data scientists and analysts who prefer Python for data-related tasks3.

These API methods enable automation, integration with enterprise dashboards, and the ability to perform batch operations, among other tasks3. Therefore, the correct answer is C. REST SDK, .NET SDK, Python SDK, as these are the open API methods supported by Qlik Enterprise Manager3.

Correct : D

For replicating columns that contain large PDFs, the appropriate data type to use in Qlik Replicate is:

D . BLOB: This stands for Binary Large Object and is the data type used for storing large binary data such as PDF files. The BLOB data type is suitable for handling the size and binary nature of PDF files1.

The other options are not suitable for the following reasons:

A . DLOB: This is not a recognized data type in Qlik Replicate.

B . NCLOB: NCLOB, or National Character Large Object, is used for storing large text data in the national character set and is not optimal for binary data like PDFs.

C . NVARCHAR(1000): NVARCHAR is a character data type with a specified length, which would not be suitable for large binary objects like PDFs due to size limitations and the nature of the data.

For more information on data types and their usage in Qlik Replicate, you can refer to the official Qlik Replicate documentation on Replicate data types.

Correct : C

To add a new source endpoint in Qlik Replicate, in addition to the connection string, username/password, and permission to the database, the presence of transactional logs is essential. Transactional logs are crucial because they record all changes made to the database, which Qlik Replicate uses to capture the data changes that need to be replicated.

Here's the process of adding a new source endpoint:

Access to the system: You must have access to the system where the endpoint resides.

Connection information: Provide the connection string, which includes the network address and other parameters needed to connect to the source database.

User credentials: Supply the username and password that have the necessary permissions to access the database.

Transactional logs: Ensure that transactional logs are available and accessible because Qlik Replicate uses these logs to track changes in the source database for replication purposes.

The requirement for transactional logs is consistent with the nature of Qlik Replicate's operation, which relies on change data capture (CDC) technology to detect and replicate database changes12.

It's important to note that while the database client (option A) and access to the database server (option D) are also important components in the overall setup, they are not specifically required to add a new source endpoint in the context of this question. File access (option B) is not directly related to the addition of a source endpoint in Qlik Replicate.

Correct : D

After a Qlik Replicate administrator creates a new task, runs a Full Load test, and turns on Change Processing, the method to test this task would be to:

Stop the task: This ensures that no active processes are running that could interfere with the testing.

Run -> Advanced Run Options: This step allows the administrator to access more specific settings that can control how the task is executed.

Start Change Processing Only: This option will start the Change Data Capture (CDC) phase without re-running the Full Load. It's used to test the CDC mechanism specifically, ensuring that changes made at the source are captured and applied to the target correctly.

This method is supported by best practices in the Qlik community and documentation, which suggest using the Advanced Run Options to control the task's behavior for testing purposes1. It allows the administrator to verify that the Change Processing is set up correctly and is functioning as expected without the need to reload the target or recreate the task entirely. This approach is efficient and effective for testing the CDC functionality in isolation.
