- A
Dedicated Interconnect
Dedicated Interconnect provides 10G/100G links, 99.99% SLA, and can scale beyond 10 Gbps with multiple connections.
- B
Classic VPN
Why wrong: Classic VPN has lower SLA (99.9%) and limited throughput.
- C
HA VPN
Why wrong: HA VPN offers 99.99% SLA but throughput limited by VPN bandwidth.
- D
Partner Interconnect
Why wrong: Partner Interconnect maxes at 10 Gbps and offers up to 99.99% SLA, but is provided via a partner; Dedicated is better for high bandwidth.

PCNE Practice Question: Designing, Planning, and Prototyping a GCP Network
This PCNE practice question tests your understanding of designing, planning, and prototyping a gcp network. 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 is planning a hybrid cloud architecture with GCP. They need a dedicated, high-bandwidth connection from their on-premises data center to GCP with 99.99% SLA and the ability to scale beyond 10 Gbps. Which connection type should they choose?
Answer choices
Why each option matters
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 an on-premises data center and Google Cloud, supporting speeds of 10 Gbps or 100 Gbps per link. It offers a 99.99% SLA when configured with redundant links (two circuits) and can scale beyond 10 Gbps by adding additional 10 Gbps or 100 Gbps connections, meeting the requirement for high bandwidth and high availability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Classic VPN
Why it's wrong here
Classic VPN has lower SLA (99.9%) and limited throughput.
- ✗
HA VPN
Why it's wrong here
HA VPN offers 99.99% SLA but throughput limited by VPN bandwidth.
- ✗
Partner Interconnect
Why it's wrong here
Partner Interconnect maxes at 10 Gbps and offers up to 99.99% SLA, but is provided via a partner; Dedicated is better for high bandwidth.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that HA VPN can match Dedicated Interconnect's bandwidth and SLA, but HA VPN is limited to 3 Gbps per tunnel and uses the public internet, making it unsuitable for high-bandwidth, dedicated connectivity needs.
Detailed technical explanation
How to think about this question
Dedicated Interconnect uses IEEE 802.1Q VLAN tagging to isolate traffic over the physical cross-connect, and each VLAN attachment can support up to 10 Gbps or 100 Gbps depending on the link speed. The 99.99% SLA requires at least two redundant connections in different edge availability domains (e.g., different metro locations) to protect against single points of failure. In practice, organizations often combine Dedicated Interconnect with Cloud Router for dynamic BGP routing (using eBGP) to manage traffic failover and load balancing across multiple links.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
