Google Professional-Cloud-Architect Exam With Confidence Using Practice Dumps

According to Google Cloud Hybrid Connectivity documentation, Cloud VPN is the standard and recommended solution for establishing a secure, encrypted connection over the public internet between an on-premises network and a Google Cloud VPC. This aligns with Cymbal’s requirement for "secure communication" while maintaining manageability. Unlike SSH tunnels (Option B), which are fragile and difficult to scale at an enterprise level, Cloud VPN utilizes IPsec protocols to create a stable and encrypted site-to-site tunnel.

To satisfy the "secure and manageable" criteria, the implementation must include strictly defined VPC Firewall Rules. This ensures the principle of least privilege is applied, restricting on-premises systems to only the necessary cloud resources and ports required for their specific business functions. VPC Peering (Option D) is technically incorrect here as it is designed for connecting two VPCs within the cloud, not for on-premises to cloud connectivity. A Bastion Host (Option A) provides a secure gateway for administrative login (SSH/RDP) but does not provide the transparent, network-level connectivity required for the automated "legacy file-based integrations" and "data transfers" mentioned in Cymbal’s environment. By using Cloud VPN with granular firewalling, Cymbal achieves a secure extension of their data center into Google Cloud.

Note: The principle of least privilege and separation of duties are concepts that, although semantically different, are intrinsically related from the standpoint of security. The intent behind both is to prevent people from having higher privilege levels than they actually need

Principle of Least Privilege: Users should only have the least amount of privileges required to perform their job and no more. This reduces authorization exploitation by limiting access to resources such as targets, jobs, or monitoring templates for which they are not authorized.

Separation of Duties: Beyond limiting user privilege level, you also limit user duties, or the specific jobs they can perform. No user should be given responsibility for more than one related function. This limits the ability of a user to perform a malicious action and then cover up that action.
