Question # 17

Your organization is implementing a new security policy to control how firewall rules are applied to control flows between virtual machines (VMs). Using Google-recommended practices, you need to set up a firewall rule to enforce strict control of traffic between VM A and VM B. You must ensure that communications flow only from VM A to VM B within the VPC, and no other communication paths are allowed. No other firewall rules exist in the VPC. Which firewall rule should you configure to allow only this communication path?

Firewall rule direction: ingress

Action: allow

Target: VM B service account

Source ranges: VM A service account

Priority: 1000

Firewall rule direction: ingress

Action: allow

Target: specific VM B tag

Source ranges: VM A tag and VM A source IP address

Priority: 1000

Firewall rule direction: ingress

Action: allow

Target: VM A service account

Source ranges: VM B service account and VM B source IP address

Priority: 100

Firewall rule direction: ingress

Question # 18

You are configuring the firewall endpoints as part of the Cloud Next Generation Firewall (Cloud NGFW) intrusion prevention service in Google Cloud. You have configured a threat prevention security profile, and you now need to create an endpoint for traffic inspection. What should you do?

Create a Private Service Connect endpoint within the zone, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

Create a firewall endpoint within the region, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

Create a firewall endpoint within the zone, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

Attach the profile to the VPC network, create a firewall endpoint within the zone, and use a firewall policy rule to apply the L7 inspection.

Question # 19

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?

Enable Firewall Rules Logging inside the third project.

Modify the existing VPC Service Controls policy to include the new project in dry run mode.

Monitor the Resource Manager audit logs inside the perimeter.

Enable VPC Flow Logs inside the third project, and monitor the logs for negative impact.

Question # 20

Your organization is deploying a single project for 3 separate departments. Two of these departments require network connectivity between each other, but the third department should remain in isolation. Your design should create separate network administrative domains between these departments. You want to minimize operational overhead.

How should you design the topology?

Create a Shared VPC Host Project and the respective Service Projects for each of the 3 separate departments.

Create 3 separate VPCs, and use Cloud VPN to establish connectivity between the two appropriate VPCs.

Create 3 separate VPCs, and use VPC peering to establish connectivity between the two appropriate VPCs.

Create a single project, and deploy specific firewall rules. Use network tags to isolate access between the departments.

Question # 21

You created a new VPC network named Dev with a single subnet. You added a firewall rule for the network Dev to allow HTTP traffic only and enabled logging. When you try to log in to an instance in the subnet via Remote Desktop Protocol, the login fails. You look for the Firewall rules logs in Stackdriver Logging, but you do not see any entries for blocked traffic. You want to see the logs for blocked traffic.

What should you do?

Check the VPC flow logs for the instance.

Try connecting to the instance via SSH, and check the logs.

Create a new firewall rule to allow traffic from port 22, and enable logs.

Create a new firewall rule with priority 65500 to deny all traffic, and enable logs.

Question # 22

Question:

You are designing the architecture for your organization so that clients can connect to certain Google APIs. Your plan must include a way to connect to Cloud Storage and BigQuery. You also need to ensure the traffic does not traverse the internet. You want your solution to be cloud-first and require the least amount of configuration steps. What should you do?

Configure Private Google Access on the VPC resource. Create a default route to the internet.

Configure Private Google Access on the subnet resource. Create a default route to the internet.

Configure Cloud NAT and remove the default route to the internet.

Configure a global Secure Web Proxy and remove the default route to the internet.

Question # 23

Question:

You need to enable Private Google Access for some subnets within your Virtual Private Cloud (VPC). Your security team set up the VPC to send all internet-bound traffic back to the on-premises data center for inspection before egressing to the internet, and is also implementing VPC Service Controls for API-level security control. You have already enabled the subnets for Private Google Access. What configuration changes should you make to enable Private Google Access while adhering to your security team's requirements?

Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record pointing to Googleâ€™s private API address range.

Change the custom route that points the default route (0/0) to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record pointing to Googleâ€™s private API address range.

Create a custom route that points Googleâ€™s private API address range to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Googleâ€™s restricted API address range.

Create a custom route that points Googleâ€™s restricted API address range to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Googleâ€™s restricted API address range.

Question # 24

You converted an auto mode VPC network to custom mode. Since the conversion, some of your Cloud Deployment Manager templates are no longer working. You want to resolve the problem.

What should you do?

Apply an additional IAM role to the Google APIâ€™s service account to allow custom mode networks.

Update the VPC firewall to allow the Cloud Deployment Manager to access the custom mode networks.

Explicitly reference the custom mode networks in the Cloud Armor whitelist.

Explicitly reference the custom mode networks in the Deployment Manager templates.
