During a connectivity test, administrators discover that traffic to external addresses is unsuccessful from a new instance, but traffic to internal addresses is working. Ping results show replies for internal addresses but no response from external addresses. Administrators suspect a route is missing. Which action best resolves this problem?
Configure a gateway entry in the instance's network settings
Change the system's DNS server to a local address
Enable a dynamic address translation policy on the instance
A gateway entry provides a path for outbound traffic. Without that path, the instance can communicate with local systems but not beyond the local network. Changing the DNS server would not address outbound traffic failure if a path does not exist. Opening ephemeral ports in the firewall would not fix the absence of a path. Enabling a dynamic address translation feature on the instance would not help if the instance has no gateway reference.
