- A
Global dynamic routing mode
Why wrong: This setting determines route propagation across regions, not route advertisement.
- B
Custom route exchange
Custom route exchange allows advertising specific prefixes via BGP.
- C
Custom learned routes
Why wrong: Custom learned routes are for GCP to accept specific routes from on-prem, not for advertising.
- D
BGP route aggregation
Why wrong: Route aggregation is not a BGP feature on Cloud Router; it's about summarizing prefixes.
- E
Route advertisement with MED
MED values influence route priority when multiple paths exist.

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.
An organization is designing a hybrid connectivity architecture using Cloud Router and BGP. They need to advertise a specific prefix from an on-premises network to GCP, and they want to control the route priority. Which two BGP features should they configure? (Choose TWO.)

Correct answer & explanation
✓
Custom route exchange
Cloud Router can advertise custom routes, and BGP allows setting MED values to influence route priority.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
