Which option allows communication of traffic between two VPCs as if they were on the same network?

• A. Private Cloud
• B. VPC Peering
• C. Public Cloud
• D. Multitenancy

Answer: (B)

Connecting two VPCs so they behave like one network relies on establishing a private inter-VPC link. VPC peering creates a direct, private connection between two VPCs, allowing instances in either VPC to communicate using their private IP addresses as if they’re on the same network. Traffic stays within the cloud provider’s network, not going out to the public internet. To enable this, you configure route tables to point to the peer VPC and adjust security groups and network ACLs to permit the traffic. Peering is non-transitive, so you can’t reach a third VPC through a peered VPC without additional connections. This method can work within the same region or across regions, depending on the provider’s capabilities. By contrast, a Private Cloud describes hosting infrastructure privately, Public Cloud is about delivering services in the cloud model, and Multitenancy refers to sharing resources among multiple tenants; none of these provide the direct inter-VPC connectivity that peering offers.
