Google Cloud Professional Cloud Developer — Question 195

You are building a highly available and globally accessible application that will serve static content to users. You need to configure the storage and serving components. You want to minimize management overhead and latency while maximizing reliability for users. What should you do?

Answer options

• A. 1. Create a managed instance group. Replicate the static content across the virtual machines (VMs) 2. Create an external HTTP(S) load balancer. 3. Enable Cloud CDN, and send traffic to the managed instance group.
• B. 1. Create an unmanaged instance group. Replicate the static content across the VMs. 2. Create an external HTTP(S) load balancer 3. Enable Cloud CDN, and send traffic to the unmanaged instance group.
• C. 1. Create a Standard storage class, regional Cloud Storage bucket. Put the static content in the bucket 2. Reserve an external IP address, and create an external HTTP(S) load balancer 3. Enable Cloud CDN, and send traffic to your backend bucket
• D. 1. Create a Standard storage class, multi-regional Cloud Storage bucket. Put the static content in the bucket. 2. Reserve an external IP address, and create an external HTTP(S) load balancer. 3. Enable Cloud CDN, and send traffic to your backend bucket.

Correct answer: D

Explanation

Option D is correct because using a multi-regional Cloud Storage bucket ensures high availability and low latency for globally distributed users. Options A and B involve managed and unmanaged instance groups, which add unnecessary complexity and management overhead for serving static content. Option C uses a regional bucket, which may not provide the same level of availability and performance as a multi-regional bucket.
