The correct answer is Virtual Private Cloud (VPC). This GCP service enables you to define and control a logically isolated virtual network environment in the cloud. Within a VPC, you can create subnets, configure IP addresses, set up firewall rules, and connect resources such as virtual machines and load balancers.
- Cloud VPN is a service in GCP that provides secure and encrypted connectivity between your on-premises network and a VPC in the cloud. It is used for establishing site-to-site VPN connections.
- Cloud DNS is a service in GCP that provides authoritative domain name system (DNS) resolution. It is used for managing DNS zones and records, translating domain names to IP addresses.
- Cloud Interconnect is a service in GCP that allows you to establish dedicated and high-bandwidth network connections between your on-premises network and a VPC in the cloud. It is used for creating private connections that bypass the public internet.
Therefore, the correct answer is Virtual Private Cloud (VPC) as it is the GCP service specifically used for creating and managing virtual networks.
