Google Cloud Digital LeaderSecurity and operations with Google CloudHard
A company is migrating its legacy applications to Google Cloud, some of which require strict network isolation and a private connection to on-premises data centers without exposing traffic to the public internet. They need to ensure that traffic between their Google Cloud VPC and their on-premises network is encrypted and secure. Which Google Cloud networking service should they use?
- ACloud Interconnect (Dedicated)
- BCloud VPN
- CCloud Load Balancing
- DCloud CDN
Show answer & explanationAnswer & explanation
Correct answer: A. Cloud Interconnect (Dedicated)
Cloud Interconnect (Dedicated) provides a direct, private physical connection between an on-premises data center and Google's network, ensuring high-bandwidth, low-latency, and highly secure communication without traversing the public internet. Cloud VPN also provides a secure connection, but Cloud Interconnect (Dedicated) is for dedicated private links.
Why the other options are wrong
- B. Cloud VPN provides secure, encrypted tunnels over the public internet, but the requirement is for a *private* connection without exposing traffic to the internet.
- C. Cloud Load Balancing distributes traffic and doesn't establish private connections to on-premises networks.
- D. Cloud CDN caches content and doesn't provide private connectivity to on-premises networks.
Cloud Interconnect (Dedicated)
Cloud Interconnect (Dedicated) provides a direct, physical connection between your on-premises network and Google's network, offering high-bandwidth, low-latency, and private connectivity.
- Dedicated physical connection, does not traverse the public internet.
- High bandwidth (10/100 Gbps) and low latency.
- Provides secure connectivity for hybrid cloud architectures.
- Ideal for sensitive workloads requiring strict network isolation.
Memory trick: Interconnect dedicates a direct, private line.
