I think option C is correct. Default routes only kick in when there's no specific route.

I feel C is the safest choice. It aligns with how routing works.

B is definitely wrong. Other routes remain active with a default route set.

D seems extreme. Communication can still happen without a default route.

A is misleading. Default route isn’t always first; it’s conditional.

B is totally wrong. Other routes aren't disabled just because a default route is set.

Wait, so if there's no default route, does that really mean no communication at all?

I’m not entirely sure, but I feel like A might be misleading since the default route isn’t always the first choice.

I remember something about default routes not disabling other routes, so B seems off to me.

I think the default route is used when there are no more specific routes available, so maybe C is correct?
