A subnet route table contains one route for the 10.0.0.0/16 prefix and another route for the 10.0.0.0/24 prefix. To which route does Azure send traffic destined for 10.0.0.5?

AThe route for 10.0.0.0/16, because it covers the wider address range hereYour answer

BBoth routes equally, because the address falls within each prefix

CThe route for 10.0.0.0/24, because it is the longest matching prefixCorrect

DThe system route for 0.0.0.0/0, because it acts as the default

Not correct

Why this is correct

C is correct.

Azure selects a route using the longest prefix match algorithm, so 10.0.0.5 follows the 10.0.0.0/24 route because that prefix is longer than 10.0.0.0/16 even though the address falls within both.

Why other options are incorrect

- A: A wider range is the shorter prefix; Azure uses longest prefix match, so the broader 10.0.0.0/16 route is not selected for 10.0.0.5.
- B: The address does fall within both prefixes, yet Azure picks only one route, selecting the longer prefix rather than both.
- D: The 0.0.0.0/0 route is the shortest prefix and is used only when no longer matching route exists for the destination.

Real-world application

When an administrator adds a narrow route to steer one subnet range while leaving broader traffic untouched, longest prefix match is what makes the specific route win for addresses inside it.

Key takeaway

Azure routes a destination to the route with the longest matching address prefix.

A destination falling inside both a broad range and a narrower one follows the narrower route, because the longer prefix wins even though the address matches both.
