Discuss Qlik QREP Exam Topic 1 Question 17

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?

AStop and resume the task

BStop task, enable__CT tables, and resume

CChange the DDL Handling Policy to accommodate this change

DStop and reload the task

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.

Wait, are you sure about that? Sounds too simple.

Hailey 11 months ago

Totally agree with Lili, that's the right approach!

Keneth 11 months ago

Stopping and reloading seems like overkill for just one column.

Alline 11 months ago

I think changing the DDL Handling Policy is the way to go.

Lili 11 months ago

You need to stop the task and enable __CT tables!

Ashlee 12 months ago

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

Maile 12 months ago

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

Bo 12 months ago

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

Mariko 1 year ago

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.

Kenny 1 year ago

Ah, I see. Changing the DDL Handling Policy could be the way to go here. I'll make sure to read through the details of each option before deciding.

Matilda 1 year ago

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.

Lawanda 1 year ago

Hmm, I'm not sure about this one. I'll need to think through the different options carefully to make sure I select the right approach.

Estrella 1 year ago

This seems straightforward - I think the answer is to stop and resume the task to replicate the change.

Option E: Hire a Qlik Replicate magician to wave their wand and make the changes happen automatically. No work required!

A) Stop and resume the task

Rosio 1 year ago

I'd go with C. Who has time to stop and resume the task every time a column is added? Ain't nobody got time for that!

Reena 1 year ago

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

Fair enough, let's go with C then. It's better to be safe than sorry.

Romana 1 year ago

↳ replying to Reena

I see your point, but I still think C is the safer choice in this situation.

Bernardo 1 year ago

↳ replying to Reena

But wouldn't stopping and resuming the task be quicker? I'm leaning towards A.

↳ replying to Reena

I think C is the best option here. Changing the DDL Handling Policy should do the trick.

Laila 1 year ago

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