I agree, A makes the most sense here.

Wait, are you sure about that?
AL

OSS event triggers are the way to go!
TA

I thought MNS was the one-way trigger?
LY

A is definitely a one-way trigger!

I have a vague memory that CloudMonitor triggers are two-way, but I can't recall the details.
LE

I practiced a similar question, and I feel like SLS triggers require configuration on both ends, but I could be wrong.
RE

I'm not entirely sure, but I remember MNS topic triggers might also be one-way.
AD

I think OSS event triggers are one-way because they only need to be set up in the OSS configuration.
PA

The key here is understanding which trigger only needs to be set up on the event source side. I think the OSS event trigger is the one-way option, but I'll double-check the details to be sure.
CL

Hmm, I'm a bit confused on the difference between one-way and two-way triggers. I'll need to review the trigger types more carefully to answer this one.
ES

I'm pretty sure the one-way trigger is the OSS event trigger, since it only needs to be configured in the event source and not in Function Compute.
BR
Brittni 1 year ago
Okay, I've got this. The one-way trigger is the OSS event trigger, because it doesn't require any additional configuration in Function Compute. The other options like CloudMonitor and MNS are two-way triggers.
AL
Allene 1 year ago
Okay, let's see. The key is to identify the valid configuration with the right combination of main DBs, application servers, and node servers. I've got a strategy for this.
PA

If the behavior is really decreasing, might we lean towards D? But I remember needing to confirm through more than just observation.
SK
Skye 1 year ago
Hmm, this seems like a tricky one. I'll need to think carefully about the different events that can be raised in a case management system.
DO
Douglass 1 year ago
Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about the correct syntax for the find command.
LE
Lea 1 year ago
One-way or two-way, as long as the function doesn't crash and burn, I'm happy!
BO

Wait, SLS triggers? I thought they were two-way. Better not guess on this one.
