A company is deploying a critical, latency-sensitive application on Google Cloud that requires extremely high bandwidth and low-latency connectivity to its on-premises data center. The existing Cloud VPN solution is not meeting the performance requirements. They need to ensure that the connection is fully redundant to avoid single points of failure. Which Cloud Interconnect option, along with its configuration, should be recommended?
- ACloud Interconnect (Partner) with redundant 10 Gbps connections to a single partner location.
- BCloud Interconnect (Dedicated) with redundant 10 Gbps connections in two different metropolitan areas.
- CCloud Interconnect (Partner) with a single attachment.
- DCloud Interconnect (Dedicated) with a single 10 Gbps connection.
Show answer & explanationAnswer & explanation
Correct answer: B. Cloud Interconnect (Dedicated) with redundant 10 Gbps connections in two different metropolitan areas.
Dedicated Interconnect offers the highest bandwidth and lowest latency by providing a direct physical connection. For full redundancy and high availability, redundant connections in different metropolitan areas are crucial to protect against both physical link failures and regional outages.
Why the other options are wrong
- A. Partner Interconnect might not meet 'extremely high bandwidth and low-latency' compared to Dedicated, and while redundant to a single partner location, it still introduces a single point of failure if that entire partner location experiences an issue.
- C. Partner Interconnect uses a service provider, which might introduce more latency than Dedicated, and a single attachment lacks redundancy.
- D. A single Dedicated Interconnect connection provides high performance but lacks redundancy, making it a single point of failure.
Cloud Interconnect Redundancy
Achieving highly available Cloud Interconnect involves configuring redundant connections across different physical paths and/or metropolitan areas.
- Dedicated or Partner Interconnect options
- Redundant connections for high availability
- Geographically diverse connections for disaster recovery
Memory trick: Reliable connections need multiple paths, like a strong rope with many strands.
