Exam Professional Cloud Architect topic 1 question 105 discussion

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 ....

Should be D

NO, VPN can't meet the low latency and high throughput requirements. dedicated interconnect is a connection between you and GCP VPC. So, you can use any IP address range (private RFC 1918 or public IP ranges)

yes, you are very smart but question says high throughput and minimizing latency > Interconnect

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
