Google Cloud Professional Cloud DevOps Engineer — Question 131

You are monitoring a service that uses n2-standard-2 Compute Engine instances that serve large files. Users have reported that downloads are slow. Your Cloud Monitoring dashboard shows that your VMs are running at peak network throughput. You want to improve the network throughput performance. What should you do?

Answer options

• A. Add additional network interface controllers (NICs) to your VMs.
• B. Deploy a Cloud NAT gateway and attach the gateway to the subnet of the VMs.
• C. Change the machine type for your VMs to n2-standard-8.
• D. Deploy the Ops Agent to export additional monitoring metrics.

Correct answer: C

Explanation

Changing the machine type to n2-standard-8 will provide more resources, including increased network throughput capabilities, which can resolve the slow download issues. Adding NICs (Option A) may not significantly increase throughput if the VM type itself is a bottleneck. Deploying a Cloud NAT gateway (Option B) helps with outbound connections but does not directly improve the VM's network performance. The Ops Agent (Option D) is for monitoring and does not enhance performance.
