An organization wants to connect their on-premises data center to Google Cloud with a dedicated 10 Gbps link. They require high availability and have budget for two physically diverse connections. Which solution should they choose?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Provision two Cloud Dedicated Interconnect connections from diverse peering points.
Cloud Dedicated Interconnect provides direct physical connections between on-premises and Google Cloud. For high availability, two separate circuits (each 10 Gbps or 100 Gbps) from diverse peering points are recommended. HA VPN is software-defined and lower bandwidth. Partner Interconnect uses a service provider but Dedicated Interconnect is preferred for dedicated bandwidth.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Partner Interconnect with a single 10 Gbps connection.
Why it's wrong here
Single connection is a single point of failure; Partner Interconnect relies on a partner, but two connections are needed for HA.
- ✗
Configure a single Dedicated Interconnect connection and use Cloud VPN as backup.
Why it's wrong here
A single Dedicated Interconnect is a single point of failure; VPN backup adds complexity and lower bandwidth.
- ✓
Provision two Cloud Dedicated Interconnect connections from diverse peering points.
Why this is correct
Two Dedicated Interconnect connections from diverse locations provide high availability and dedicated bandwidth.
- ✗
Deploy a single HA VPN tunnel.
Why it's wrong here
HA VPN provides up to 3 Gbps per tunnel and is software-defined; does not provide dedicated 10 Gbps.
