Google Associate Cloud EngineerEnsuring successful operation of a cloud solutionHard
A large enterprise has a hybrid cloud environment, with critical on-premises applications needing to communicate securely and privately with services hosted in Google Cloud. They require high bandwidth and low latency, and the connection must be highly available and redundant. Which networking solution should be implemented to meet these requirements?
- APeering with another VPC network
- BShared VPC
- CCloud VPN
- 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 network and Google Cloud, offering high bandwidth, low latency, and high availability/redundancy, which is crucial for critical hybrid cloud applications.
Why the other options are wrong
- A. Peering with another VPC network is for connecting two VPC networks within Google Cloud, not for connecting on-premises to Google Cloud.
- B. Shared VPC allows multiple projects to use a common VPC network, but it doesn't address the need for connecting on-premises infrastructure to Google Cloud.
- C. Cloud VPN uses encrypted tunnels over the public internet, which offers lower bandwidth and higher latency compared to direct physical connections, and might not meet 'high bandwidth and low latency' for critical applications.
Cloud Interconnect (Dedicated)
A Google Cloud networking service that provides a direct, private physical connection between an on-premises data center and Google's network.
- Offers higher bandwidth and lower latency compared to Cloud VPN.
- Provides a more secure and reliable connection as traffic does not traverse the public internet.
- Can be configured for high availability with redundant connections.
