This PCA practice question tests your understanding of manage and provision cloud infrastructure. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Which THREE are valid methods to connect an on-premises network to a Google Cloud VPC?
Dedicated Interconnect
Dedicated Interconnect provides direct physical connection.
Cloud VPN
Cloud VPN provides encrypted tunnels over the internet.
Cloud Router
Why wrong: Cloud Router is used for BGP dynamic routing, not as a connection method.
VPC peering
Why wrong: VPC peering connects VPCs, not on-premises networks.
Partner Interconnect
Partner Interconnect connects through a supported partner.
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 (A) provides a direct physical connection between your on-premises network and Google Cloud, offering high bandwidth and a Service Level Agreement (SLA) of up to 99.99% availability. It uses a cross-connect in a colocation facility to attach your on-premises router to a Google Cloud router, enabling private, low-latency connectivity to your VPC without traversing the public internet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates confuse Cloud Router as a standalone connectivity method, when it is actually a routing component that must be paired with a VPN tunnel or Interconnect to function.
Detailed technical explanation
Under the hood, Dedicated Interconnect uses IEEE 802.1Q VLAN tagging to segregate traffic over a single physical link, and BGP sessions are established between your on-premises router and Google's router to exchange routes. For high availability, you must provision at least two redundant links (each in a different edge availability domain) to meet the SLA; a single link does not qualify. In a real-world scenario, enterprises with large data volumes (e.g., 50+ Gbps) often choose Dedicated Interconnect over VPN to avoid internet bandwidth caps and latency variability.
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.
