GCP PCA · Question 50 · Manage implementation and optimize costs

A media company serves terabytes of video content daily to users globally. They are currently serving the videos directly from Cloud Storage buckets in the US, resulting in high network egress costs and high latency for users in Asia and Europe. Which TWO architectural changes should you implement to reduce costs and improve performance? (Select TWO)

Answer options:

A.

Place a Global External HTTP(S) Load Balancer in front of the Cloud Storage bucket.

B.

Enable Cloud CDN on the Load Balancer's backend bucket.

C.

Replicate the Cloud Storage bucket to regions in Asia and Europe.

D.

Change the Cloud Storage class to Coldline.

E.

Configure Cloud Interconnect to all major ISPs globally.

How to approach this question

Identify the GCP service designed to cache static content at the edge.

Full Answer

Place a Global External HTTP(S) Load Balancer in front of the Cloud Storage bucket., Enable Cloud CDN on the Load Balancer's backend bucket.
To optimize delivery of static content (like videos), you should use Cloud CDN. Cloud CDN requires a Global External HTTP(S) Load Balancer. You configure the Cloud Storage bucket as a 'backend bucket' to the load balancer and enable Cloud CDN. Content is cached at Google's edge nodes worldwide. This improves performance (lower latency) and reduces costs (CDN cache egress is significantly cheaper than direct GCS internet egress).

Common mistakes

Suggesting bucket replication, which increases storage costs and doesn't lower the high internet egress fees.
