Exam Professional Cloud Architect topic 4 question 4 discussion

Answer : D (based on the requirement of secure and high-performance connection between on-premises systems to Google Cloud) Between A and D, picked D as with Direct Connect EHR can get the bandwidth of 10 GBS to 100GBS (VPN ruled out as traffic is over internet and due to bandwidth. Direct Peering is more for Workspace rather than Google Cloud)

If we notice this line in question - "Google's recommended practices for production-level applications" and then see overview of these 2 pages- https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/production-level-overview and https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/non-critical-overview. It is clear answer should be D , which is topology for production level applications recommended by Google

Answer is clearly D: https://cloud.google.com/network-connectivity/docs/interconnect/concepts/best-practices#scenarios

For me is D. By Technical requirement we need to establish a stable, low-latency connection between on-prem and cloud

simple hint : in this EHR case study, whenever there is a network connection, it's a dedicated interconnect answer !

The recommended solution for hybrid connectivity between on-premises systems and Google Cloud is to configure two Dedicated Interconnect connections in two different metros (cities). This ensures that EHR Healthcare has a redundant connection to Google Cloud, with each connection providing a separate physical path. Placing the Interconnect connections in different metro zones also helps to ensure that the connection is resilient to failures in a single geographic region. This solution meets the business requirement of providing a secure and high-performance connection between on-premises systems and Google Cloud, as well as the technical requirement of maintaining regulatory compliance. It also helps to meet the requirement of providing consistent logging, log retention, monitoring, and alerting capabilities, as Dedicated Interconnect connections can be used in conjunction with Cloud Router to establish a connection between on-premises networks and Google Cloud VPC networks.

EHR is supposed to be massive in size. so the option of 100 GBps / Dedicated is warranted.

D is the correct answer

D is ok

Business requirements for this case: * Provide a minimum 99.9% availability for all customer-facing systems. * Provide a secure and high-performance connection between on-premises systems and Google Cloud. A. - builds us a 99.9% SLA partner interconnect, covering all business requirements. B. - VPN is not suitable for the business requirements. C. - Direct peering is used for workspace, instead of DMZ, again - not suitable. D. - builds us a 99.99% SLA dedicated interconnect, covering all business requirements. The answer to choosing A or D lies in the question, stating: "You want to follow Google's recommended practices for production-level applications." Google recommends using the 99.99% SLA interconnect (dedicated or partner) for production-level applications as stated here: https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/production-level-overview The answer is D.

The case study requires 99.9% availability. Only the setup with two partner interconnects in two metro zones serves 99.9% https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/partner-creating-999-availability D is wrong since 99.9% availability does not require 4 interconnects in two metros and case study mentions to keep costs low.

two points to note: - requirements says a minimum of 99.9% (not 99.99%) - also, "Decrease infrastructure administration costs."

I think D is more suitable because it requires low latency and more spread out datacenter locations. Moreover, it is not necessarily the location of the legacy datacenter support provider interconnect

D seems to be the correct answer

vote D

case study says " Provide a minimum 99.9% availability for all customer-facing systems", i think minimum is the keyword , hence I would go with D

Both A and D will work, but they want the SLA 99.9% and keep the cost low, which is possible with A (cost low)
