compute-networking-servicesDescribe Azure architecture and servicesEasy

A VM in an Azure virtual network has no public IP and sits behind no load balancer. What outbound internet access does it have?

Outbound connectivity only after a route table is createdAzure routes to the internet by default. Route tables exist to override that routing, not to establish it.
No outbound connectivity until a public IP is assignedA public IP is needed for inbound reachability, not for a VM to reach out. Outbound already works without one.
Outbound connectivity only through a NAT gateway resourceA NAT gateway gives outbound traffic a predictable set of source addresses. It replaces the default path rather than creating it.
Outbound connectivity by default from the virtual networkCorrect · your answerCorrect: nothing has to be added for traffic to leave. The other options manage or replace that default path.
No outbound connectivity until a load balancer fronts itA public load balancer provides inbound distribution and can manage outbound. Neither role is a precondition for outbound access.

Correct.

Concept

A private address space in Azure is not sealed on the way out. Inbound reachability must be granted deliberately, while outbound traffic leaves unless something is configured to stop it.

Why D

The overview states that all resources in a virtual network can communicate outbound with the internet by default. A public IP, NAT gateway, or public load balancer manages that path or serves inbound traffic, rather than enabling the outbound path in the first place.
