Exam Professional Cloud Architect topic 1 question 172 discussion

The correct answer is: D. Create a managed instance group with Compute Engine instances. Create a global load balancer and configure it with two backends: Managed instance group, Cloud Storage bucket. Enable Cloud CDN on the bucket backend. This solution will improve the performance of the application by: Automatically scaling the number of Compute Engine instances to meet demand. Distributing traffic across multiple instances to reduce load on each instance. Caching popular songs in memory to reduce the number of times that they need to be loaded from Cloud Storage. Using a global load balancer to distribute traffic evenly across all regions. Using Cloud CDN to deliver files to users from a location that is closer to them. This solution is the most efficient and cost-effective way to improve the performance of the application.

A is Ridiculous.

The point here is thar music and cloud CDN is something that it's a good match.

The correct answer is D. https://cloud.google.com/cdn?hl=en#static-content

D. Absolutely

Not agree on A , why pay unnecessary for same data for VM disk size.

The Cloud CDN is the best practice for the content caching.

I would recommend option D, creating a managed instance group with Compute Engine instances and a global load balancer with two backends: the managed instance group and the Cloud Storage bucket, and enabling Cloud CDN on the bucket backend. This approach would allow you to scale the number of instances in the managed instance group as needed to handle the demand for the application, and would also use the Cloud CDN to improve the performance of the application by caching the music files closer to the users. Option A, mounting the Cloud Storage bucket using gcsfuse on all backend Compute Engine instances, would not provide a way to scale the number of instances to handle increased demand for the application.

D Is the Correct Answer

D is ok

I think it should be A,

Why not A, I think it should be A, since it mentioned popular songs and file store is faster then the cloud storage, I vote for A

I will go with D

Do not trust the official answers here, D is correct. In special for this question, never use gcsfuse in production. Performance is bad and reliability is trashy - Google states it themselves.

D is correct

Remember Gcsfuse performance is not good, reference https://cloud.google.com/storage/docs/gcs-fuse#notes

A is wrong because you can't be serving files directly from Compute Engine instance. GCS + CDN is best option
