Question 18 of 169
Single answerYou 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?
