This PCA practice question tests your understanding of designing and planning a cloud solution architecture. 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 needs to connect their on-premises data center to Google Cloud with a dedicated, low-latency connection that provides a Service Level Agreement (SLA) of 99.99% uptime. They anticipate high bandwidth usage (10 Gbps). Which connectivity option should they choose?
Cloud VPN with static routing
Why wrong: VPN runs over the internet, no SLA on uptime, limited bandwidth.
Cloud CDN
Why wrong: CDN is for content delivery, not connectivity.
Partner Interconnect
Why wrong: Uses a service provider; bandwidth up to 10 Gbps but SLA may vary.
Dedicated Interconnect
Direct private connection, up to 10 Gbps, 99.99% SLA with redundancy.
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 physical connection between on-premises and GCP, offers up to 10 Gbps per circuit, and comes with a 99.99% SLA when configured with redundant connections.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Cloud VPN with static routing
Why it's wrong here
VPN runs over the internet, no SLA on uptime, limited bandwidth.
Cloud CDN
Why it's wrong here
CDN is for content delivery, not connectivity.
Partner Interconnect
Why it's wrong here
Uses a service provider; bandwidth up to 10 Gbps but SLA may vary.
Dedicated Interconnect
Why this is correct
Direct private connection, up to 10 Gbps, 99.99% SLA with redundancy.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCA NAT questions on configuration and troubleshooting.
