Google Professional Data Engineer Exam - Topic 1 Question 15 Discussion

You need to move 2 PB of historical data from an on-premises storage appliance to Cloud Storage within six months, and your outbound network capacity is constrained to 20 Mb/sec. How should you migrate this data to Cloud Storage?
A) Use Transfer Appliance to copy the data to Cloud Storage
B) Use gsutil cp --J to compress the content being uploaded to Cloud Storage
C) Create a private URL for the historical data, and then use Storage Transfer Service to copy the data to Cloud Storage
D) Use trickle or ionice along with gsutil cp to limit the amount of bandwidth gsutil utilizes to less than 20 Mb/sec so it does not interfere with the production traffic

Trickle and ionice are clever, but might complicate things.

I thought Storage Transfer Service needed a direct connection?

Isn't 2 PB a lot to move in just six months?

I disagree, gsutil cp with compression could work too.

Transfer Appliance is definitely the way to go for large data!

I practiced a similar question about bandwidth management with gsutil, and using trickle or ionice sounds like a viable option to avoid network congestion.

I feel like the Storage Transfer Service could be useful, but I can't recall if it works with private URLs.

I'm not entirely sure, but I think compressing data with gsutil might not help much if the network is already so slow.

I remember we discussed using Transfer Appliance for large data migrations in class. It seems like a good fit for this scenario.

This is a good question to test our understanding of VRRP-A configuration. I'm going to read through the options carefully and try to eliminate the incorrect ones.

Hmm, this one seems a bit tricky. I'm thinking we need to make sure all the invoices for the period are paid, and that the invoice and payment journals are properly posted in the General Ledger. Gotta cover all our bases.

Okay, let's see. I think the key is using the ipadm command to set the forwarding property on the interfaces. But I'm not sure about the exact syntax to enable it globally and then disable it on a specific interface.

I remember a practice question where we had to prioritize frame rate, so I think option A might be a key factor here. But I'm worried I might be misremembering.

This looks like a pretty straightforward question. I'd go with option C - using rpm to install the program's binaries from an RPM package. That's the most direct and reliable way to install software on an RPM-based system.
