- A
Create a global external HTTPS load balancer with serverless NEGs pointing to each regional Cloud Run service, and attach a Google-managed certificate.
The global load balancer uses anycast IP and routes to the closest healthy backend, and serverless NEGs integrate with Cloud Run.
- B
Enable anycast on the Cloud Run service by selecting the 'global' setting in the Cloud Run region selection.
Why wrong: Cloud Run does not support anycast natively.
- C
Use Cloud DNS with geo-routing policy to point users to the appropriate regional load balancer IP based on their location.
Why wrong: This uses multiple IPs, not anycast.
- D
Configure Cloud CDN in front of the Cloud Run services to cache responses at edge locations.
Why wrong: CDN caches but does not route traffic to nearest backend; it serves from cache or origin.
Quick Answer
The correct answer is to create a global external HTTPS load balancer with serverless NEGs pointing to each regional Cloud Run service, and attach a Google-managed certificate. This works because a global external HTTPS load balancer uses Google Front Ends (GFEs) with a single anycast IP, automatically routing users to the nearest healthy backend based on proximity and capacity, while serverless NEGs allow the load balancer to directly target regional Cloud Run services without needing an intermediary. On the Google Professional Cloud Developer exam, this scenario tests your understanding of global versus regional load balancing and how serverless NEGs integrate with Cloud Run for multi-region deployments. A common trap is confusing Cloud CDN or geo-based DNS routing with true anycast; CDN caches content but doesn’t route by locality, and DNS geo-routing uses multiple IPs, not a single anycast address. Memory tip: think “GFE + NEG = global anycast for serverless.”
PCD Integrating Google Cloud services Practice Question
This PCD practice question tests your understanding of integrating google cloud services. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Your organization runs a multi-region application on Cloud Run that serves an API. The API is consumed by clients worldwide. You want to reduce latency by routing users to the nearest regional Cloud Run service. Currently, all traffic goes to a single Cloud Run service in us-central1. You have set up additional Cloud Run services in europe-west1 and asia-east1. Each service is fronted by an external HTTPS load balancer with a regional backend. You want to use a single global anycast IP address that automatically directs users to the closest healthy backend. You also need to support HTTPS with a custom domain and a Google-managed certificate. What should you do?
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
Create a global external HTTPS load balancer with serverless NEGs pointing to each regional Cloud Run service, and attach a Google-managed certificate.
Option D is correct because an External HTTPS Load Balancer with a global backend service can route traffic to the closest backend via the Google Front Ends (GFE). The regional Cloud Run services can be added as backends with the appropriate network endpoint groups (NEGs). Option A is wrong because Cloud CDN caches content but does not route based on locality. Option B is wrong because Cloud DNS with geo-routing can direct to different IPs, but that is not a single anycast IP. Option C is wrong because Cloud Run does not support anycast itself.
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.
