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.

With option A, daily data would take 27 hours. My answer is B. How do you think?

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).

direct peering can not be the option in practice, the reality is to use gsutil -m option

Selected Answer: B

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.

Selected Answer: C

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)
