Your organization's security policy requires that all internet-bound traffic return to your on-premises data center through HA VPN tunnels before egressing to the internet, while allowing virtual machines (VMs) to leverage private Google APIs using private virtual IP addresses 199.36.153.4/30. You need to configure the routes to enable these traffic flows.
What should you do?

  1. Configure a custom route 0.0.0.0/0 with a priority of 500 whose next hop is the default internet gateway.
    Configure another custom route 199.36.153.4/30 with priority of 1000 whose next hop is the VPN tunnel back to the on-premises data center.
  2. Configure a custom route 0.0.0.0/0 with a priority of 1000 whose next hop is the internet gateway. Configure another custom route 199.36.153.4/30 with a priority of 500 whose next hop is the VPN tunnel back to the on-premises data center.
  3. Announce a 0.0.0.0/0 route from your on-premises router with a MED of 1000. Configure a custom route 199.36.153.4/30 with a priority of 1000 whose next hop is the default internet gateway.
  4. Announce a 0.0.0.0/0 route from your on-premises router with a MED of 500. Configure another custom route 199.36.153.4/30 with a priority of 1000 whose next hop is the VPN tunnel back to the on-premises data center.

Answer(s): C



Your company has defined a resource hierarchy that includes a parent folder with subfolders for each department. Each department defines their respective project and VPC in the assigned folder and has the appropriate permissions to create Google Cloud firewall rules. The VPCs should not allow traffic to flow between them. You need to block all traffic from any source, including other VPCs, and delegate only the intra- VPC firewall rules to the respective departments.
What should you do?

  1. Create a VPC firewall rule in each VPC to block traffic from any source, with priority 0.
  2. Create a VPC firewall rule in each VPC to block traffic from any source, with priority 1000.
  3. Create two hierarchical firewall policies per department's folder with two rules in each: a high-priority rule that matches traffic from the private CIDRs assigned to the respective VPC and sets the action to allow, and another lower-priority rule that blocks traffic from any other source.
  4. Create two hierarchical firewall policies per department's folder with two rules in each: a high-priority rule that matches traffic from the private CIDRs assigned to the respective VPC and sets the action to goto_next, and another lower-priority rule that blocks traffic from any other source.

Answer(s): D



You have two Google Cloud projects in a perimeter to prevent data exfiltration. You need to move a third project inside the perimeter; however, the move could negatively impact the existing environment. You need to validate the impact of the change.
What should you do?

  1. Enable Firewall Rules Logging inside the third project.
  2. Modify the existing VPC Service Controls policy to include the new project in dry run mode.
  3. Monitor the Resource Manager audit logs inside the perimeter.
  4. Enable VPC Flow Logs inside the third project, and monitor the logs for negative impact.

Answer(s): B



You are configuring an HA VPN connection between your Virtual Private Cloud (VPC) and on-premises network. The VPN gateway is named VPN_GATEWAY_1. You need to restrict VPN tunnels created in the project to only connect to your on-premises VPN public IP address: 203.0.113.1/32.
What should you do?

  1. Configure a firewall rule accepting 203.0.113.1/32, and set a target tag equal to VPN_GATEWAY_1.
  2. Configure the Resource Manager constraint constraints/compute.restrictVpnPeerIPs to use an allowList consisting of only the 203.0.113.1/32 address.
  3. Configure a Google Cloud Armor security policy, and create a policy rule to allow 203.0.113.1/32.
  4. Configure an access control list on the peer VPN gateway to deny all traffic except 203.0.113.1/32, and attach it to the primary external interface.

Answer(s): B



Your company has recently installed a Cloud VPN tunnel between your on-premises data center and your Google Cloud Virtual Private Cloud (VPC). You need to configure access to the Cloud Functions API for your on-premises servers. The configuration must meet the following requirements:

Certain data must stay in the project where it is stored and not be exfiltrated to other projects.

Traffic from servers in your data center with RFC 1918 addresses do not use the internet to access Google

Cloud APIs.
All DNS resolution must be done on-premises.

The solution should only provide access to APIs that are compatible with VPC Service Controls.

What should you do?

  1. 1. Create an A record for private.googleapis.com using the 199.36.153.8/30 address range.
    2. Create a CNAME record for *.googleapis.com that points to the A record.
    3. Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.
    4. Remove the default internet gateway from the VPC where your Cloud VPN tunnel terminates.
  2. 1. Create an A record for restricted.googleapis.com using the 199.36.153.4/30 address range.
    2. Create a CNAME record for *.googleapis.com that points to the A record.
    3. Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.
    4. Configure your on-premises firewalls to allow traffic to the restricted.googleapis.com addresses.
  3. 1. Create an A record for restricted.googleapis.com using the 199.36.153.4/30 address range.
    2. Create a CNAME record for *.googleapis.com that points to the A record.
    3. Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.
    4. Remove the default internet gateway from the VPC where your Cloud VPN tunnel terminates.
  4. 1. Create an A record for private.googleapis.com using the 199.36.153.8/30 address range.
    2. Create a CNAME record for *.googleapis.com that points to the A record.
    3. Configure your on-premises routers to use the Cloud VPN tunnel as the next hop for the addresses you used in the A record.
    4. Configure your on-premises firewalls to allow traffic to the private.googleapis.com addresses.
