After rolling out a new configuration in a cloud environment, every service becomes unreachable. Logs show that the instances are running but there is no inbound or outbound traffic. Which action would address the system-wide downtime?
Override DNS settings with public resolvers
Increase instance resource pools to handle traffic spikes
Remove user accounts to address privilege violations
Review and adjust the gateway definition in the routing table
Adjusting the gateway definition in the routing table restores the correct data path for inbound and outbound requests. Without a proper default route, requests cannot flow between these instances and external clients. Removing user accounts does not resolve a networking shortfall. Changing DNS addresses is unlikely to fix routing table misconfigurations. Increasing resource tiers addresses capacity, not a traffic flow problem.
