Question-46: The process of replicating and then transferring data across locations inside a firm is referred to as replication. Recovery Time Objective (RTO) and Recovery Point Objective are the usual units of measurement used for it (RPO). PURPOSE. The primary goals of backup are to ensure compliance and facilitate granular recoveries, including the long-term storage of company documents. Your organisation has come to the conclusion that it would benefit from constructing a backup duplicate of their user authentication PostgreSQL database on Google Cloud Platform. The database is 4 terabytes, and there are regular updates of significant size. Replication needs private address space communication. Which method of social networking should you employ?
A. The Dedicated Interconnect Service Offered by Google Cloud.
B. A Google Cloud VPN that is connected to the network of the data center.
C. A NAT and TLS translation gateway that is installed on the premises of the organization.
D. An instance of Google Compute Engine that has a VPN server already installed and is connected to the network of the data center.

: 1 Explanation: Direct connect is private. VPN not enough for 4 TB with huge frequent changes. Let's go with option elimination Option-1. Google Cloud Dedicated Interconnect >> Secured, fast connection, hence the choice. This will allow private connection from GCP to the data center with a fast connection. Cost is not mentioned in the requirement to eliminate this option. Option-2. Google Cloud VPN connected to the data center network >> We have to think about data flowing on the internet and the requirement talks about private connect. Also not sure how well you connect VPN with Data Center until you use the hybrid option. Option-3 A NAT and TLS translation gateway installed on-premises >>This is a VM option to reach outside won't for this requirement hence eliminate Option-4. A Google Compute Engine instance with a VPN server installed connected to the data centre network >>This is a slow option hence eliminate. VPN is not private, it is public but encrypted. Also, VPN is not suitable for large updates that happen frequently. Its a DB replication of 4 TB which will be continuous so Dedicated Interconnect is cost effective when data volume and traffic is high. - Any other option will be costly because of ingress & egress high volume traffic - Dedicated Interconnect it can also communicate based on private IP range - replicating sensitive data like users data over public internet using Cloud VPN is not a good option from security perspective. - Dedicated Interconnect traffic will not go over the internet.
