Show Suggested Answer

Suggested 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.

For detailed hardware recommendations for different scales of Qlik Replicate systems, you can refer to the official Qlik documentation on Recommended Hardware Configuration.

You need to stop the task and enable __CT tables!

Stopping and reloading the task seems like a safe option, but I wonder if it's overkill for just adding a column.

I feel like the DDL Handling Policy could be relevant, but I can't recall the exact steps to change it.

I remember something about enabling __CT tables when changes are made. That might be the right approach here.

I think we might need to stop the task and resume it, but I'm not entirely sure if that's enough for a new column.

Okay, let's see. Stopping and resuming the task seems like the most logical step, but I want to double-check the other choices just to be sure.

D? Really? Stopping and reloading the entire task sounds like a nuclear option. Let's keep it simple with C.

I'm torn between B and C. Enabling the __CT tables might be a bit overkill, but it could cover all bases. Decisions, decisions.
