Google PCA Design and plan a cloud solution architecture Practice Question
A company is migrating to Google Cloud and needs to connect their on-premises network to a VPC. They require high bandwidth and a reliable connection with a Service Level Agreement (SLA). Which solution should they choose?
⚠ Common exam trap
Many exam-takers confuse Partner Interconnect with Dedicated Interconnect, assuming any 'Interconnect' offers an SLA, but only Dedicated Interconnect provides a direct physical link with a 99.99% SLA, while Partner Interconnect's SLA depends on the partner's network and is typically lower.

Correct answer & explanation
✓
Dedicated Interconnect
Dedicated Interconnect provides a direct, private physical connection between your on-premises network and Google's network, offering high bandwidth (10 or 100 Gbps per link) and a 99.99% uptime SLA when configured with redundant links. This meets the requirements for high bandwidth and a reliable, SLA-backed connection better than any other option.
