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.
An organization requires a hybrid connectivity option that offers an SLA of 99.99% availability and supports bandwidth up to 100 Gbps. They are willing to manage their own physical infrastructure in a Google colocation facility. Which connectivity solution should they choose?
Cloud VPN with multiple tunnels
Why wrong: SLA 99.9%, bandwidth up to 3 Gbps per tunnel.
Dedicated Interconnect
Direct physical connection with high SLA and bandwidth.
Partner Interconnect
Why wrong: SLA is 99.9%, bandwidth up to 10 Gbps per attachment.
HA VPN
Why wrong: SLA 99.99% but bandwidth limited to 3 Gbps per tunnel.
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 is the correct choice because it provides a direct, private connection between your on-premises network and Google Cloud, supporting bandwidth up to 100 Gbps (via multiple 10 Gbps or 100 Gbps links) and offering a 99.99% availability SLA when configured with redundant attachments. This solution requires you to manage your own physical infrastructure in a Google colocation facility, meeting the organization's requirement for self-managed hardware.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Google Cloud often tests the distinction between Dedicated and Partner Interconnect, where candidates mistakenly choose Partner Interconnect because they overlook the requirement for the organization to manage its own physical infrastructure, assuming any 'Interconnect' option meets the SLA and bandwidth needs.
Detailed technical explanation
Dedicated Interconnect uses VLAN attachments (Layer 2) over a cross-connect in a Google colocation facility, with each attachment supporting up to 10 Gbps or 100 Gbps; to achieve 99.99% availability, you must configure at least two redundant attachments in different zones or locations. Under the hood, this leverages Google's private network backbone, bypassing the public internet entirely, which reduces latency and jitter while providing a consistent SLA. A real-world scenario is a financial services firm requiring low-latency, high-throughput connectivity for real-time trading data, where even milliseconds of internet variability are unacceptable.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
