Google Associate Cloud EngineerPlanning and configuring a cloud solutionHard
A financial institution needs to migrate its on-premises data center to Google Cloud. They require a dedicated, high-bandwidth (10 Gbps+) connection with extremely low latency, and they need to extend their on-premises network to Google Cloud with private IP addressing. Which networking solution should they choose?
- ACloud VPN
- BDirect Peering
- CCloud Interconnect (Partner Interconnect)
- DCloud Interconnect (Dedicated Interconnect)
Show answer & explanationAnswer & explanation
Correct answer: D. Cloud Interconnect (Dedicated Interconnect)
Dedicated Interconnect provides a direct, private physical connection between an on-premises data center and Google's network, offering high bandwidth (10 Gbps or 100 Gbps), extremely low latency, and private IP connectivity, which perfectly matches the requirements of a financial institution needing maximum performance and security.
Why the other options are wrong
- A. Cloud VPN provides encrypted tunnels over the public internet, which is not suitable for high-bandwidth, extremely low-latency, and dedicated private connections.
- B. Direct Peering allows direct connection to Google's network for public traffic, but it's not designed for extending a private on-premises network with private IP addresses or guaranteeing specific bandwidth/latency for private traffic.
- C. Partner Interconnect uses a service provider's network to connect, which offers lower bandwidth options and potentially higher latency than Dedicated Interconnect.
Dedicated Interconnect
A physical, direct connection between your on-premises network and Google's network, providing high bandwidth and low latency private connectivity.
- Direct physical connection (10 Gbps or 100 Gbps)
- Private IP connectivity
- Low latency and high throughput
