Google Professional Cloud Network Engineer Exam - Topic 9 Question 31 Discussion

Actual exam question for Google's Professional Cloud Network Engineer exam

Question #: 31
Topic #: 9

[All Professional Cloud Network Engineer Questions]

You are using a 10-Gbps direct peering connection to Google together with the gsutil tool to upload files to Cloud Storage buckets from on-premises servers. The on-premises servers are 100 milliseconds away from the Google peering point. You notice that your uploads are not using the full 10-Gbps bandwidth available to you. You want to optimize the bandwidth utilization of the connection.

What should you do on your on-premises servers?

ATune TCP parameters on the on-premises servers.

BCompress files using utilities like tar to reduce the size of data being sent.

CRemove the -m flag from the gsutil command to enable single-threaded transfers.

DUse the perfdiag parameter in your gsutil command to enable faster performance: gsutil perfdiag gs://[BUCKET NAME].

Wait, 100 ms latency? How is that even acceptable for 10 Gbps?

Using perfdiag is a good idea, but will it really make a difference?

Removing the -m flag? That sounds counterintuitive.

I think compressing files could help too, right?

Definitely tune TCP parameters, that's a must!

The perfdiag option sounds familiar; I think it helps diagnose performance issues, but I'm not clear if it actually optimizes the upload speed directly.

I practiced a similar question where we had to decide on using multi-threading with gsutil. I feel like removing the -m flag might actually slow things down instead of speeding them up.

I think compressing files could help, but I wonder if the time spent compressing would offset the benefits of reduced upload size.

I remember we discussed tuning TCP parameters in class, but I'm not entirely sure which specific parameters would help with bandwidth utilization.

I'm a bit confused on this one. I'm not familiar with the ACCS system, so I'm not sure which tools would be the best to use. I'll need to review the material again to make sure I understand the context.

I'm leaning towards option D. The question specifically mentions using the default Console service name, and option D says to choose "twistlock-console" as the identifier and run the curl | bash script. That sounds like it might be the easiest way to get the Defenders deployed.
