Google ACE Deploying and implementing a cloud solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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 deploying a global web application using an external HTTPS load balancer with Cloud CDN. Which THREE steps are required for proper configuration? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Cloud CDN on the backend bucket
A is correct because Cloud CDN must be explicitly enabled on the backend bucket (or backend service) to cache content at Google's edge points of presence. Without this step, the load balancer will forward requests directly to the origin without leveraging CDN caching, defeating the purpose of a global web application.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Enable Cloud CDN on the backend bucket
Why this is correct
Cloud CDN must be enabled on the backend bucket to cache content.

✗
Enable Identity-Aware Proxy (IAP)
Why it's wrong here
IAP is for access control, not a requirement for CDN.
✗
Use an external TCP load balancer
Why it's wrong here
TCPload balancer does not support HTTPS or CDN; HTTP(S) load balancer is required.
✓
Configure a health check for the backend services
Why this is correct
Health checks are required to ensure traffic is only sent to healthy instances.

✓
Use Premium Tier networking
Why this is correct
Premium Tier provides a global anycast IP and is required for global load balancing with CDN.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between HTTP(S) and TCP load balancers, and candidates mistakenly think a TCP load balancer can serve HTTPS traffic or work with Cloud CDN, but Cloud CDN only works with HTTP(S) load balancers.
Detailed technical explanation
How to think about this question
Cloud CDN uses Google's global edge cache network to serve content from locations closest to users, reducing latency and origin load. The backend bucket must have Cloud CDN enabled and a valid origin (e.g., Cloud Storage bucket) with public access or signed URLs. Health checks are required for backend services (not buckets) to ensure traffic is only sent to healthy instances, but for a bucket-based backend, health checks are not applicable—though the question's context implies a backend service with instances, making D correct. Premium Tier networking ensures traffic uses Google's global fiber backbone for optimal routing and lower latency, which is essential for a global web application.

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
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
