This PCA practice question tests your understanding of manage and provision cloud infrastructure. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 Google Cloud Dedicated Interconnect connection options?
High availability (HA) with two 10 Gbps circuits.
HA option provides redundancy.
10 Gbps single circuit.
Standard capacity option.
IPsec VPN tunnel as a backup to the interconnect.
Why wrong: This is a VPN, not an interconnect option.
Partner Interconnect offering via a service provider.
Why wrong: Partner Interconnect is a different product, not a Dedicated Interconnect option.
100 Gbps single circuit.
Higher capacity option.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
High availability (HA) with two 10 Gbps circuits.
Option A is correct because Google Cloud Dedicated Interconnect supports high availability configurations using two 10 Gbps circuits to provide redundancy and meet SLA requirements. This setup ensures that if one circuit fails, traffic can be rerouted through the other, maintaining connectivity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Google Cloud often tests the distinction between Dedicated Interconnect and Partner Interconnect, and the fact that IPsec VPN is a separate backup option, not a connection type for Dedicated Interconnect.
Detailed technical explanation
Dedicated Interconnect provides direct physical connections between your on-premises network and Google's network, using either 10 Gbps or 100 Gbps circuits, and supports multiple VLAN attachments via 802.1Q trunking. For high availability, you must provision at least two circuits from different edge availability domains (metro zones) to protect against facility-level failures, and you can use BGP sessions with MED or AS-path prepending for traffic engineering.
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.
