GCP PCA · Question 23 · Network Topologies

Your company is migrating a data-intensive application to Google Cloud. The application requires a hybrid connection to an on-premises database. The connection must guarantee 10 Gbps of bandwidth and have an SLA of 99.99%. Which connectivity option should you choose?

Answer options:

A.

HA VPN

B.

Partner Interconnect

C.

Dedicated Interconnect

D.

Carrier Peering

How to approach this question

Match the bandwidth requirement (10 Gbps) and SLA (99.99%) to the enterprise hybrid connectivity product.

Full Answer

C.Dedicated Interconnect✓ Correct
Cloud Interconnect (specifically Dedicated Interconnect) provides direct, physical connections between your on-premises network and Google's network. It is designed for high-throughput (10 Gbps or 100 Gbps) and low-latency data transfers. By provisioning multiple circuits across different metropolitan areas, you can achieve the required 99.99% SLA.

Common mistakes

Choosing HA VPN (Option A). While HA VPN offers the right SLA, it relies on the public internet, meaning bandwidth and latency cannot be strictly guaranteed at 10 Gbps.
