[All Professional Cloud Architect Questions]


The migration of JencoMart's application to Google Cloud Platform (GCP) is progressing too slowly. The infrastructure is shown in the diagram. You want to maximize throughput.
What are three potential bottlenecks? (Choose three.)

  • A. A single VPN tunnel, which limits throughput
  • B. A tier of Google Cloud Storage that is not suited for this task
  • C. A copy command that is not suited to operate over long distances
  • D. Fewer virtual machines (VMs) in GCP than on-premises machines
  • E. A separate storage layer outside the VMs, which is not suited for this task
  • F. Complicated internet connectivity between the on-premises infrastructure and GCP

I don't get why B isn't correct. Cloud Storage isn't a good replacement for SAN, especially when we have a database running on some of the VMs.

Single VPN tunnel limits throughput. Copying 20TB across long distances is a big bottleneck. VPN across internet cannot be relied upon for high performance

Why "A" dudes? even if you put 20 tunnels connection the bandwidth of on premisses remains the same. I'm sure its B, D, F, who make's migrations know google storage isn't made for migrations, i think D means that make some compression process or transformation and F is right cause all connectivity goes trough internet. If for some reason the internet bw is shared this can be congestionated.

ACF, though there are a lot of room to imagine in answer B to make it a risk. Not sure what the test designer is implying in this case.

Looking at the figure is confusing. The necessary information cannot be read from this figure. Therefore, select the factors that deteriorate the throughput from the options. I think A,C and F are factors that deteriorate the throughput. Anyone pls tell me why choose E?

There is just not enough data in this q to answer correctly. For instance it does not state they r using a copy command and we don’t know what the internet connection is. I think adf but this q needs more data points

"E. A separate storage layer outside the VMs, which is not suited for this task". My question here is that there is no 'storage layer' in the diagram given in the question.

Answer is A,C,F. Breakdown: A. A single VPN tunnel, which limits throughput. Recommended practice is to have two redundant connections, usually Dedicated Interconnect and VPN. VPNs suit low volume data connections so won't cut it for this company. C. A copy command that is not suited to operate over long distances. Advisable to use GCP recommended tools that support multi-part, parallel composite and resumable uploads to Cloud Storage. F. Complicated internet connectivity between the on-premises infrastructure and GCP. With some existing VMs being dual-homed, firewalls, VPC and routing configs, things could get pretty complicated.

But for C it mentions specifically the long distance, and the copy command problem would happen independent of distance, right?
