Quick Answer
The answer is Dedicated Interconnect, as it is the only Google Cloud connectivity option that offers a guaranteed 99.99% SLA with bandwidth starting at 10 Gbps per circuit. This solution provides a direct, private physical connection between your on-premises data center and Google Cloud, bypassing the public internet for consistent, low-latency performance. The 99.99% SLA is achieved by configuring dual connections over diverse physical paths, which also enables a 99.999% uptime target for mission-critical workloads. On the Google Professional Cloud Network Engineer exam, this question tests your ability to distinguish Dedicated Interconnect from Partner Interconnect, which offers lower bandwidth tiers and a 99.9% SLA, or from VPNs, which lack any SLA. A common trap is assuming that 10 Gbps bandwidth alone points to Partner Interconnect, but only Dedicated Interconnect provides the 99.99% SLA guarantee at that speed. Memory tip: think “Dedicated for Direct and Dependable” — Dedicated Interconnect is the only option that delivers both the high bandwidth floor and the top-tier SLA.
This PCNE practice question tests your understanding of implementing hybrid interconnectivity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company requires a dedicated connection from their on-premises data center to Google Cloud with a guaranteed SLA of 99.99% and bandwidth starting at 10 Gbps. Which connectivity option meets these requirements?
Direct Peering
Why wrong: Not for VPC connectivity; no SLA.
Cloud VPN
Why wrong: No dedicated bandwidth guarantee; no SLA.
Dedicated Interconnect
Offers 10 Gbps or higher and 99.99% SLA.
Partner Interconnect
Why wrong: SLA is 99.9%, not 99.99%, and bandwidth may be limited.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Dedicated Interconnect
Dedicated Interconnect provides a direct, private physical connection between your on-premises network and Google Cloud, supporting bandwidths of 10 Gbps or 100 Gbps per circuit. It offers a 99.99% or 99.999% SLA depending on the configuration (e.g., dual connections with diverse paths), meeting the guaranteed SLA and bandwidth requirements specified in the question.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Partner Interconnect
Why it's wrong here
SLA is 99.9%, not 99.99%, and bandwidth may be limited.
Common exam traps
Google Cloud often tests the misconception that Partner Interconnect can match Dedicated Interconnect's SLA and bandwidth guarantees, but Partner Interconnect's SLA is typically limited to the partner's network and does not meet the 99.99% requirement without additional redundancy from the partner.
Detailed technical explanation
Dedicated Interconnect uses IEEE 802.1Q VLAN tagging to isolate traffic over the physical cross-connect, with each VLAN representing a single attachment (VLAN attachment) that can support up to 10 Gbps. For a 99.99% SLA, you must provision two redundant circuits (e.g., two 10 Gbps links) in different edge availability domains, and the SLA is calculated based on the combined availability of both circuits. In a real-world scenario, a financial services firm requiring low latency and high throughput for real-time trading would choose Dedicated Interconnect over Partner Interconnect to avoid third-party latency and ensure direct Google backbone access.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
