Your company has an application running on multiple Compute Engine instances. You need to ensure that the application can communicate with an on-premises service that requires high throughput via internal IPs, while minimizing latency. What should you do?
For an application running on multiple Compute Engine instances that requires high throughput via internal IPs while minimizing latency when communicating with an on-premises service, the best option is to configure a Cloud Dedicated Interconnect connection. Cloud Dedicated Interconnect provides a direct physical connection between your on-premises environment and Google Cloud, offering significantly higher throughput and lower latency compared to solutions that involve VPN tunnels traversing the public internet. This ensures the application can achieve the necessary performance levels for both throughput and latency.
Ans ) D , Reason : high throughput via internal IPs
This is tricky questions , it can be achieved by C and D ... Multiple Computes and Costs .. they are trying to test knowledge on VPN and Tunnels ....
IMHO the correct answer is D. Reason: "requires high throughput via internal IPs, while minimizing latency" - both are aspects you cannot guarantee with using VPN traversing the internet.
Internal IP + high throughput
Highthoughput connection VPN - No Interconnect - Y via Internal IP addresses. VPN - yes Interconnect - Y Interconnect yes for both so D
D. Configure a Cloud Dedicated Interconnect connection between the on-premises environment and Google Cloud. A Cloud Dedicated Interconnect is a high-bandwidth, low-latency network connection that allows you to connect your on-premises environment to Google Cloud Platform (GCP) using a dedicated network connection. It provides a direct physical connection between your on-premises network and GCP, which can help to reduce latency and increase the throughput of your application.
Option A, using OpenVPN to configure a VPN tunnel between the on-premises environment and Google Cloud, is not a recommended approach. OpenVPN is a free and open-source software application that implements virtual private network (VPN) techniques to create secure point-to-point connections. While OpenVPN can be used to establish a VPN tunnel between an on-premises environment and GCP, it may not provide the level of performance and reliability required for high-throughput applications. Option B, configuring a direct peering connection between the on-premises environment and Google Cloud, is not a recommended approach. Direct Peering is a high-bandwidth, low-latency network connection that allows you to connect your on-premises network directly to Google's network. While Direct Peering can be used to connect your on-premises environment to GCP, it is typically used for high-bandwidth workloads such as video streaming and may not be suitable for applications that require low latency. Option C, using Cloud VPN to configure a VPN tunnel between the on-premises
Cloud VPN, would also involve routing traffic over the public internet and would not provide the low latency and high throughput that you need.
Yeah, direct peering is high bandwidth and low latency, but may not be suitable for applications that require low latency. Good job, ChatGPT...
Ans ) D , Reason : high throughput via internal IPs
Initially thought 'D' but the question says 'high throughput via internal IPs' so go with VPN answer 'C'
How is C marked a correct one?
D cause you need high throughput
high throughput => D
D is ok
It can´t be VPN, Only interconnect can minimizing latency. D is the right answer.
D - high throughput
Communication through internal IPs - VPN. So, C

yes, you are very smart but question says high throughput and minimizing latency > Interconnect
It should be D, since need to communicate via Internal IP
Justo be D
Should be D
Should be D as high throughput
