Question 8

You are creating a new application and require access to Cloud SQL from VPC instances without public IP addresses.

Which two actions should you take? (Choose two.)

Options:

Activate the Service Networking API in your project.

Activate the Cloud Datastore API in your project.

Create a private connection to a service producer.

Create a custom static route to allow the traffic to reach the Cloud SQL API.

Question 9

You have configured a service on Google Cloud that connects to an on-premises service via a Dedicated Interconnect. Users are reporting recent connectivity issues. You need to determine whether the traffic is being dropped because of firewall rules or a routing decision. What should you do?

Options:

Use the Network Intelligence Center Connectivity Tests to test the connectivity between the VPC and the on-premises network.

Use Network Intelligence Center Network Topology to check the traffic flow, and replay the traffic from the time period when the connectivity issue occurred.

Configure VPC Flow Logs. Review the logs by filtering on the source and destination.

Configure a Compute Engine instance on the same VPC as the service running on Google Cloud to run a traceroute targeted at the on-premises service.

Question 10

You have an application hosted on a Compute Engine virtual machine instance that cannot communicate with a resource outside of its subnet. When you review the flow and firewall logs, you do not see any denied traffic listed.

During troubleshooting you find:

• Flow logs are enabled for the VPC subnet, and all firewall rules are set to log.

• The subnetwork logs are not excluded from Stackdriver.

• The instance that is hosting the application can communicate outside the subnet.

• Other instances within the subnet can communicate outside the subnet.

• The external resource initiates communication.

What is the most likely cause of the missing log lines?

Options:

The traffic is matching the expected ingress rule.

The traffic is matching the expected egress rule.

The traffic is not matching the expected ingress rule.

The traffic is not matching the expected egress rule.
