Qlik QREP Qlik Replicate Certification Exam Practice Test

Answer : D

When using LogStream staging for replication in Qlik Replicate, the Staging folder is compressed and stored on the Qlik Replicate server itself. Here's the process:

A Log Stream Staging task is defined to replicate changes from the source endpoint to the Log Stream Staging folder1.

This task creates a ''Staging'' file in the Log Stream Staging folder, which contains the changes from the source database transaction log as a compressed binary file1.

The storage path for the streamed data, which includes the Staging folder, must be specified in the Log Stream target endpoint settings, and it is explicitly stated that this path should be located on the Replicate Server machine2.

Therefore, the correct answer is D. On the Qlik Replicate server, as the staging folder is located on the machine where Qlik Replicate server is running, and it is where the compressed staging files are stored12.

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 : B, D, E

In Qlik Replicate, the options to read the log files are located in the following places:

In Diagnostic package (B): The diagnostic package in Qlik Replicate includes various log files that can be used for troubleshooting and analysis purposes1.

In Data directory of Installation (D): The log files are written to the log directory within the data directory. This is the primary location where Qlik Replicate writes its log files, and it is not possible to change this location2.

In Monitor of Qlik Replicate (E): The Monitor feature of Qlik Replicate allows users to view and manage log files. Users can access the Log Viewer from the Server Logging Levels or File Transfer Service Logging Level sub-tabs1.

The other options provided do not align with the locations where log files can be read in Qlik Replicate:

A . In Windows Event log: This is not a location where Qlik Replicate log files are stored.

C . In External monitoring tool: While external monitoring tools can be used to read log files, they are not a direct feature of Qlik Replicate for reading log files.

F . In Enterprise Manager: The Enterprise Manager is a separate component that may manage and monitor multiple Qlik Replicate instances, but it is not where log files are directly read.

Therefore, the verified answers are B, D, and E, as they represent the locations within Qlik Replicate where log files can be accessed and read21.

Answer : D

In Qlik Replicate, when multiple schema rename rules are applied, the final schema name is determined by the last applied setting that affects the schema name directly. Here's how the process works:

Global Transformation to rename schema to 'USER1': This rule will initially rename the schema from 'HR' to 'USER1'. However, this is not the final schema name as further changes are applied later in the task settings1.

Task Settings -> Target Metadata to enter the Target table schema as 'USER2': This setting overrides the previous global transformation rule and sets the target schema name to 'USER2'. This is because the Target Metadata settings are applied after the Global Transformations and directly affect the target schema name1.

Global Transformation to add a new column named 'SCHEMA' with expression as 'USER3': While this rule adds a new column with a value of 'USER3', it does not change the schema name itself. It only affects the content of a column within the tables1.

Therefore, the final target schema name, after considering all the applied settings, is D. USER2. This is because the Target Metadata setting in the task settings has the final say on the target schema name, and it is set to 'USER2'1.

Answer : A, B, D

When configuring Oracle as a source endpoint for Qlik Replicate, there are several key prerequisites that need to be met:

Enable supplemental logging (A): Supplemental logging is crucial for capturing the changes in the Oracle database accurately, especially for Change Data Capture (CDC) operations. It ensures that all necessary column data is logged for replication purposes1.

Install the Oracle Instant Client (B): The Oracle Instant Client provides the necessary libraries for Qlik Replicate to connect to and interact with the Oracle database. It's required for the proper functioning of Qlik Replicate2.

Enable ARCHIVELOG mode (D): ARCHIVELOG mode is necessary for the Oracle database to archive redo logs, which Qlik Replicate uses to capture changes. This mode allows the database to continue functioning and preserve the logs even after a log switch, which is essential for CDC1.

The other options provided are not listed as key prerequisites for configuring Oracle as a source endpoint in Qlik Replicate:

C . Complete a full backup of the source: While it's a good practice to have a backup, it's not a prerequisite for configuring the source endpoint.

E . Provide Oracle read-only privileges: Read-only privileges might be necessary for certain operations, but they are not listed as a key prerequisite.

F . Configure Oracle Recovery Model: This is not mentioned as a prerequisite in the Qlik Replicate documentation.

Therefore, the verified answers are A, B, and D, as they represent the necessary steps to configure Oracle as a source endpoint in Qlik Replicate12.

Answer : B

When merging databases, especially of such large sizes (12 TB and 15 TB), it is crucial to ensure data integrity and consistency. The recommended approach is to:

Stop the Replication Task: This is important to prevent any changes from being replicated to the target while the IBM load process is ongoing.

Perform the IBM Load: Execute the IBM load to merge the database into the existing database.

Resume the Replication Task: Once the IBM load has been successfully completed, the replication task can be resumed.

This approach ensures that the data loaded via IBM load is not missed or duplicated in the target database. It also allows Qlik Replicate to continue capturing changes from the point where the task was stopped, thus maintaining the continuity of the replication process.

It's important to note that creating a new task after the IBM load (Option D) could lead to complexities in managing the data consistency and might require additional configuration. Continuing to run the task (Option C) could result in conflicts or data integrity issues during the load process. Therefore, Option B is the safest and most reliable approach to ensure a smooth merge of the databases.

For further details and best practices, you can refer to the official Qlik Replicate documentation and support articles which provide guidance on similar scenarios1234.

Answer : C

To run a Qlik Replicate Task at a high-performance level, the main hardware components that are recommended include:

Cores: A higher number of cores is beneficial for handling many tasks running in parallel and for prioritizing full-load performance1.

SSD (Solid State Drive): SSDs are recommended for optimal performance, especially when using a file-based target or dealing with long-running source transactions that may not fit into memory1.

Network bandwidth: Adequate network bandwidth is crucial to handle the data transfer requirements, with 1 Gbps for basic systems and 10 Gbps for larger systems being recommended1.

The other options do not encompass all the recommended hardware components for high-performance levels in Qlik Replicate tasks:

A . SSD, RAM: While these are important, they do not include the network bandwidth component.

B . Cores, RAM: This option omits the SSD, which is important for disk performance.

D . RAM, Network bandwidth: This option leaves out the cores, which are essential for processing power.
