Exam Professional Cloud Architect topic 1 question 131 discussion

Answer should be D, https://cloud.google.com/load-balancing/docs/https/setting-up-https-serverless#gcloud:-cloud-functions https://cloud.google.com/blog/products/networking/better-load-balancing-for-app-engine-cloud-run-and-functions

IMHO it is d), not b). Reason is that you don't need Cloud Spanner just to store user data - FireStore is the better solution. Additionally, I see no indications concerning the requirement to use GKE... Please correct me when I am wrong.

D correct answer

C. Even though Cloud CDN is not a storage system, option C implies that static content is served through a CDN-enabled LB (usually backed by Cloud Storage). This fits well with the requirement for cost-efficiency, scalability, and LB. Option D is valid too, but it doesn’t mention LD and uses Firestore, which may not fit structured user data. Therefore, C remains the best match for Google’s exam logic.

This question doesn't have a correct answer!!! Re-read the question again "You want to leverage Cloud Load Balancing" Option D doesn't come with load balancer options plus Cloud function is good for event-triggering tasks not necessarily for sustained high-traffic API endpoints. Option C can work but there is no storage provided! Cloud CDN is for Caching, NOT for permanent storage.

This question is more about costs so Cloud storage+firestore

B is absolutely diabolical for "Cost effective"

As per ChatGPT , answer is C

xcvxcv

Answer is D. Solution should be cost effective and highly reliable. Cloud storage and firestore is suitable .

absolutely D because kubernetes is not cost effective. cloud functions are a better shot

CDN is for caching. For static website hosting a storage bucket is a good choice, thus A and C are eliminated. B, Cloud Spanner, my nightmare. I accidentally created an empty cloud spanner and it burned like 30-40 USD per day! I got a huge amount of billing from GCP that month! No way to be cost-effective. D, Cloud Functions are good for simple API services and have no cost if not in use. SQL or NoSQL for user data is not a strong factor here, either should be fine.

The correct answer with the lowest cost is D

in B) it says zonal GKE with worker nodes in multiple zones how zonal and in multiple zones?! And that 100% eliminate B

Actually it is B. Highly reliable, using Load Balancer, Spikes and several API. D is less reliable, as functions will take long to cold start and will have a time out and not using LB. The only draw back is cost.

User data in a relational database is not a good option, A B C are ruled out. Left with D - User data in Firestore.

D is the correct option since CDN is not for storage of html content, so you have only the option B and D. And the option B required that you have a containerezed application in other way, you can't use k8s. So the option is D.
