A large enterprise with an on-premises data center needs to establish a secure, high-bandwidth, and low-latency connection to their Google Cloud VPC network. They require a dedicated physical connection with a service level agreement (SLA) for availability. Which Google Cloud networking product is the most appropriate for this scenario?
- ACloud Router
- BCloud VPN
- CCloud Interconnect (Dedicated)
- DDirect Peering
Show answer & explanationAnswer & explanation
Correct answer: C. Cloud Interconnect (Dedicated)
Dedicated Cloud Interconnect provides a direct, physical connection between an on-premises network and Google's network, offering high bandwidth, low latency, and an SLA. This meets the requirements for a secure, high-performance, and reliable connection, which is superior to VPN for bandwidth and latency, and different from Direct Peering which is for public IP access to Google services.
Why the other options are wrong
- A. Cloud Router enables BGP peering and dynamic routing for both Cloud VPN and Cloud Interconnect, but it is a component, not the primary connection product itself.
- B. Cloud VPN provides secure tunnels over the public internet, which may not meet high-bandwidth, low-latency, or SLA requirements.
- D. Direct Peering allows customers to exchange internet traffic with Google at an exchange point, primarily for public Google services, not a dedicated private connection to a VPC with an SLA.
Dedicated Cloud Interconnect
A Google Cloud service that provides a direct, physical connection between an on-premises network and Google's network, offering high bandwidth, low latency, and an SLA.
- Dedicated physical connection
- High bandwidth (10/100 Gbps), low latency
- Offers an SLA for availability
Memory trick: Interconnect is the dedicated highway to the cloud.
