Yeah, the row layout must match, no doubt about it!

Wait, can you really use a Dummy step for this? Sounds odd.

Append streams is the go-to for this kind of join!

Definitely need identical row layouts for a proper union.

I believe the row layout can differ as long as the data types match, but I need to double-check that against the material we covered.

I feel like I saw a question about using the Dummy step in a similar context, but I can't recall if it actually joins flows or just passes data through.

I think the row layout has to be identical for the union to work properly, but I could be mixing that up with another concept.

I remember practicing with the Append streams step, but I'm not entirely sure if it's the only option for joining flows.

I think the Dummy (do nothing) step is a bit of a trick answer. That's not really a way to join data flows - it's just a placeholder step. I'm confident B and D are the right choices.

The Append streams step is the way to go here. It's designed specifically for combining data flows. As long as the data types match up, you can use it even if the row layout isn't identical.

Hmm, I'm a bit confused on this one. I know we need to perform a union, but I'm not sure which steps to use. I'll have to review the material on joining data flows in PDI.

I'm pretty sure the correct answers are B and D. The row layout must be identical between the two steps, and the data types can be different as long as they're compatible.

I'm a bit confused on this one. I know the different components in a Splunk cluster, but I'm not sure which one is responsible for discovering new indexers. I'll need to think it through carefully.

Okay, let's see here. I think the key is to find a way to hide the false positives without compromising the overall security posture. I'll need to think through the implications of each choice.

The 'Dummy (do nothing)' step? Sounds like something straight out of a Monty Python sketch! But seriously, B and D are the correct answers.

B and D seem like the obvious choices to me. The row layout has to match, but the data types can be different as long as they're compatible. Easy peasy!
