PCNE Practice Question: Designing, Planning, and Prototyping a GCP Network
A company is planning a hybrid connectivity solution with 200 Gbps total bandwidth between their data center and Google Cloud. They need the highest SLA and lowest latency. Which combination of services would meet these requirements?
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
✓
Two 100 Gbps Dedicated Interconnect connections
Dedicated Interconnect provides up to 100 Gbps per link. To achieve 200 Gbps, they need two 100 Gbps connections. Two connections provide redundancy and the 99.99% SLA.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Two 100 Gbps Dedicated Interconnect connections
Why this is correct
Two 100 Gbps connections provide 200 Gbps bandwidth and meet the highest SLA (99.99%) and lowest latency.
- ✗
One 100 Gbps Dedicated Interconnect and one 100 Gbps Partner Interconnect
Why it's wrong here
Mixing types may cause asymmetric routing and does not provide the highest SLA.
- ✗
Twenty 10 Gbps Dedicated Interconnect connections
Why it's wrong here
While possible, managing 20 connections is operationally complex and inefficient compared to two 100 Gbps links.
- ✗
Four 50 Gbps Partner Interconnect connections
Why it's wrong here
Partner Interconnect has lower latency and SLA (99.9% or 99.99% depending on setup, but typically less than Dedicated) and 50 Gbps is not a standard speed.
