What is the maximum number of VM instances allowed in a single network when considering VPC peering?

The maximum number of Virtual Machine (VM) instances allowed in a single network when considering VPC peering is 15,000. This limit is important when designing solutions that require multiple VM instances within a Virtual Private Cloud (VPC) environment, particularly when you plan to use VPC peering to connect different networks.

The 15,000 instance limit is part of the resource quotas established by Google Cloud to ensure smooth operation and performance. If your architecture involves multiple networks that need to communicate through VPC peering, you must account for this limit when planning your resources. Additionally, knowing the limitations helps in designing scalable applications that can grow without hitting resource boundaries.

Other options, while all higher than the correct answer, do not reflect the limits imposed by Google Cloud for VM instances in a single peered network configuration. Understanding these limits is crucial for effective network design and resource management in the cloud environment.
