An administrative application is running on a virtual machine (VM) in a managed group at port 5601 inside a Virtual Private Cloud (VPC) instance without access to the internet currently. You want to expose the web interface at port 5601 to users and enforce authentication and authorization Google credentials

What should you do?

A.
Modify the VPC routing with the default route point to the default internet gateway Modify the VPC Firewall rule to allow access from the internet 0.0.0.0/0 to port 5601 on the application instance.

Configure Secure Shell Access (SSH) bastion host in a public network, and allow only the bastion host to connect to the application on port 5601. Use a bastion host as a jump host to connect to the application
Suggested answer: C

Explanation:

This approach allows you to expose the web interface securely by using Identity-Aware Proxy (IAP), which provides authentication and authorization with Google credentials. The HTTP Load Balancer can distribute traffic to the VMs in the managed group, and the VPC firewall rule ensures that access is allowed from the IAP network range.
