A is too manual for such a large volume of data.

Wait, why would you use HDFS? Isn't that outdated?

I think B could work too, but it's not as scalable.

I feel like I might be mixing up the roles of Cloud Pub/Sub and Dataflow. I hope I remember the details correctly during the exam!

I practiced a similar question where we had to choose between Cloud Storage and BigQuery for storage. I think option D could be the right choice here.

I'm not entirely sure, but I think using Cloud SQL might not be the best for scalability with that much data.

I remember we discussed the importance of decoupling producers and consumers, which makes me lean towards options that use Pub/Sub.

Option A seems like the easiest approach - just merge the intermediate cert with the web server cert. But I'm not 100% sure if that's the recommended way to do it. I'll have to double-check the Apache documentation to be sure.

I'm a little confused by all the abbreviations here. Let me think this through step-by-step - government audits are conducted to certain standards, INTOSAI sets standards for government organizations, and IFAC provides additional guidance. I'll have to double-check the answer choices to make sure I have it right.

I've got this one! The answer is definitely Hazard. The question is describing a potential hazardous situation that could arise, so Hazard is the most accurate choice here.

I think the balanced scorecard focuses on four main areas, but I can't recall all of them. I remember "customer" is definitely one, but I'm unsure about the rest.

I'm a bit stumped on this one. All of these options sound like potential ways the government could monitor its citizens. I'll have to make an educated guess and hope for the best. Maybe I can eliminate one or two and then choose the best remaining option.
