Your company is building a new architecture to support its data-centric business focus. You are responsible for setting up the network. Your company's mobile and web-facing applications will be deployed on-premises, and all data analysis will be conducted in GCP. The plan is to process and load 7 years of archived .csv files totaling 900 TB of data and then continue loading 10 TB of data daily. You currently have an existing 100-MB internet connection.
What actions will meet your company's needs?

  • A. Compress and upload both archived files and files uploaded daily using the gsutil ג€"m option.
  • B. Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish a connection with Google using a Dedicated Interconnect or Direct Peering connection and use it to upload files daily.
  • C. Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish one Cloud VPN Tunnel to VPC networks over the public internet, and compress and upload files daily using the gsutil ג€"m option.
  • D. Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish a Cloud VPN Tunnel to VPC networks over the public internet, and compress and upload files daily.

ok but dedicated connection is available from 10 GBPS right where as in question it says internet connection is 100 MB, to me D is correct.

Dedicated Interconnect will be a new connection and will not run over the existing internet connection. With dedicated interconnect the existing ISP becomes irrelevant. If you were trying to use VPN the existing internet connection would be relevant. Answer is B.

Direct peering is meant only to connect to G Suite Services. Its reference may invalidate the whole answer.

True. B is the most apt answer with just this extra bit "direct peering" raising some confusion.

Agree B. 100Mbps connections for 10TB data transfer is takes too long https://cloud.google.com/solutions/transferring-big-data-sets-to-gcp#close

even with 100MB internet it's slow. It's 800 Mbps and transfer for 10 TB will take 2 days

There is no such thing as a "100MB" internet connection :) . That must be a speed (per second), and I would guess that the "B" is just a typo (it is highly atypical to measure bandwidth in Bps).

Option B is the correct answer, but the term "or Direct Peering connection" is probably a typo. Direct peering is GCP to GCP service NOT an on-prem to GCP service.

Selected Answer: B
Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. (In this case is the more appropriated solution) Establish a connection with Google using a Dedicated Interconnect or Direct Peering connection and use it to upload files daily. (Because of the size Dedicated interconnect or peering performs better and offer a better latency)

Selected Answer: B
B would be correct as pubsub b service might redeliver messages. When you receive messages in order and the Pub/Sub service redelivers a message with an ordering key, Pub/Sub maintains order by also redelivering the subsequent messages with the same ordering key. The Pub/Sub service redelivers these messages in the order that it originally received them.

I don't think the company needs "dedicated intereconnect" - because it is clearly said that the company wants to do "data-centric" business. Dedicated interconnect is more for having private-access to google cloud. C seems like a correct option to me

It's B, transferring over 100mbps 10TB daily is not possible, because could take up to 12 days.. You need a better connection.

Answer B => Dedicated interconnect will provide a private network with 10gbs. The internet limited to 100 mb is not possible to use cloud VPN ( it will use public internet so be limited for the daily)
