PCNE Practice Question: Designing, Planning, and Prototyping a GCP Network
A company needs to connect multiple branch offices to GCP using Partner Interconnect. They need at least 99.9% availability and bandwidth between 50 Mbps and 10 Gbps. Which type of Partner Interconnect should they choose?
⚠ Common exam trap
The PCNE exam often tests the misconception that higher SLA numbers are always better, but the trap here is that the 99.99% SLA requires dual connections, which is overkill for a 99.9% requirement, and candidates may overlook the specific SLA tiers tied to connection redundancy.

Correct answer & explanation
✓
Single connection with 99.9% SLA
Partner Interconnect offers two SLA tiers: 99.9% for a single connection and 99.99% for dual connections. Since the requirement is at least 99.9% availability and bandwidth between 50 Mbps and 10 Gbps, a single connection with 99.9% SLA meets both criteria without the cost and complexity of dual connections.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Single connection with 99.99% SLA
Why it's wrong here
Single connection cannot achieve 99.99% SLA; two connections are needed.
- ✓
Single connection with 99.9% SLA
Why this is correct
99.9% SLA meets the requirement and is typically sufficient for branch offices.
- ✗
Classic VPN
Why it's wrong here
Classic VPN is not an interconnect option and provides lower bandwidth.
- ✗
Dual connection with 99.99% SLA
Why it's wrong here
This exceeds the requirement and is more expensive.
