A company requires a highly available and low-latency connection from their on-premises data center to Google Cloud. They need dedicated bandwidth and a service level agreement (SLA) for uptime. Which networking service should they choose?
- ADirect Peering
- BCloud Interconnect (Partner)
- CCloud Interconnect (Dedicated)
- DCloud VPN
Show answer & explanationAnswer & explanation
Correct answer: C. Cloud Interconnect (Dedicated)
Dedicated Interconnect provides a direct, high-bandwidth connection between your on-premises data center and Google's network. It offers dedicated capacity and an SLA, making it ideal for highly available, low-latency, and performance-sensitive workloads.
Why the other options are wrong
- A. Direct Peering connects your network to Google's at a peering location, but it's primarily for exchanging internet traffic, not for private, direct connectivity to your Google Cloud VPC with an SLA.
- B. Partner Interconnect uses a service provider to connect to Google Cloud, which can also offer an SLA and dedicated bandwidth, but Dedicated Interconnect is the direct Google-provided solution when a direct connection to a Google PoP is feasible and desired.
- D. Cloud VPN provides encrypted connections over the public internet, which does not guarantee dedicated bandwidth or an SLA for uptime and latency.
