A manufacturing company uses several legacy applications hosted on-premises that require low-latency access to their data. They are migrating some of their data analytics workloads to Google Cloud and need to establish a dedicated, private, and high-bandwidth connection between their on-premises data center and their Google Cloud VPC network. Which networking solution should they implement?
- ADedicated Interconnect
- BCloud VPN
- CDirect Peering
- DShared VPC
Show answer & explanationAnswer & explanation
Correct answer: A. Dedicated Interconnect
Dedicated Interconnect provides a direct, private, high-bandwidth connection with lower latency and higher availability guarantees than Cloud VPN, making it ideal for connecting on-premises data centers to GCP for demanding workloads.
Why the other options are wrong
- B. Cloud VPN uses public internet, which doesn't guarantee high bandwidth or low latency for demanding workloads.
- C. Direct Peering is for direct connection to Google's network for public services, not for connecting to a private VPC.
- D. Shared VPC is a network sharing model within GCP, not for connecting on-premises networks.
Dedicated Interconnect
A physical, direct connection between an on-premises network and Google's network, providing private, high-bandwidth, low-latency connectivity.
- Dedicated physical connection.
- Private network traffic, bypassing public internet.
- High bandwidth (10 Gbps or 100 Gbps ports).
- Lower latency and higher reliability than VPN.
Memory trick: For a dedicated, fast lane to the cloud, use Interconnect.
