Answer: Change the machine type for your VMs to n2-standard-8.
To improve the network throughput performance of your VMs serving large files, the most effective solution among the provided options is to change the machine type to one with higher network performance. The n2-standard-8 machine type offers higher network throughput compared to the n2-standard-2, which is currently at peak network throughput. Adding additional NICs (Option A) does not directly increase the network throughput of a single VM instance. Deploying a Cloud NAT gateway (Option B) is more about enabling instances without external IPs to access the internet, not improving throughput. Deploying the Ops Agent (Option D) is for monitoring and does not affect network performance.
