Google Associate Cloud EngineerPlanning and configuring a cloud solutionMedium
A financial institution is migrating its highly regulated on-premises applications to Google Cloud. They require a private, dedicated, and highly secure network connection between their data center and Google Cloud, with guaranteed bandwidth and minimal latency. The connection must support thousands of VLANs and provide a 99.99% availability SLA. Which Google Cloud networking product best fits these requirements?
- ACloud VPN
- BDedicated Interconnect
- CDirect Peering
- DPartner Interconnect
Show answer & explanationAnswer & explanation
Correct answer: B. Dedicated Interconnect
Dedicated Interconnect provides a direct physical connection between the customer's on-premises network and Google's network, offering private, dedicated, high-bandwidth, low-latency connectivity with an SLA up to 99.99% for a redundant setup. It supports multiple VLAN attachments.
Why the other options are wrong
- A. Cloud VPN uses IPsec tunnels over the public internet, which doesn't guarantee bandwidth or provide the lowest latency, and is less secure than a dedicated physical connection for highly regulated data.
- C. Direct Peering allows direct network connection for public traffic exchange, not private connectivity to a VPC, and doesn't offer the same SLA or VLAN support for private resources.
- D. Partner Interconnect uses a service provider's network to connect to Google Cloud, which might not offer the same level of dedicated control or guaranteed bandwidth as a direct Dedicated Interconnect.
Dedicated Interconnect
A direct, private physical connection between an on-premises data center and Google's network, offering high bandwidth, low latency, and enhanced security for critical workloads.
- Direct physical connection
- Guaranteed bandwidth and low latency
- Supports multiple VLAN attachments
- 99.99% SLA with redundant setup
- Private connection, bypassing the public internet
Memory trick: Interconnect is for deep, dedicated connections, VPN is for quick, secure tunnels.
