How do you enable Private Google Access on a subnet?

You enable it by setting the 'Private Google Access' option to 'On' in the subnet's configuration in the VPC network.

intermediate

Can VMs with external IP addresses use Private Google Access?

Yes, VMs with external IPs can use Private Google Access, but it is primarily designed for VMs without external IPs to access Google services privately.

intermediate

What happens if Private Google Access is disabled on a subnet?

VMs without external IPs in that subnet cannot reach Google APIs or services unless they have other routes or proxies.

What does Private Google Access allow?

A VMs to access the internet through a firewall

B VMs to get public IP addresses automatically

C External users to access private VMs

D VMs without external IPs to access Google APIs privately

Private Google Access lets VMs without external IPs reach Google APIs using internal IPs.

How do you enable Private Google Access?

A Enable it on the subnet in the VPC network settings

B Assign external IPs to all VMs

C Create a firewall rule to allow internet traffic

D Install a VPN on each VM

Private Google Access is enabled per subnet in the VPC network configuration.

Which VMs benefit most from Private Google Access?

A VMs with public IP addresses

B VMs without external IP addresses

C VMs in different cloud providers

D On-premises servers

Private Google Access is for VMs without external IPs to access Google services privately.

What is a key security benefit of Private Google Access?

A Keeps traffic within Google's network without using the public internet

C Disables firewall rules automatically

D Encrypts VM disks

It keeps traffic inside Google's network, reducing exposure to the public internet.

If Private Google Access is off, what happens to VMs without external IPs?

A They can access Google APIs through the internet

B They get external IPs automatically

C They cannot reach Google APIs or services

D They can access Google APIs only via VPN

Without Private Google Access, VMs without external IPs cannot reach Google services.

Explain what Private Google Access is and why it is useful.

Think about how VMs without public IPs can still reach Google services safely.

Describe how to enable Private Google Access and what happens if it is disabled.

Focus on subnet configuration and VM access behavior.
