Alternative routing

B.
Diverse routing

Explanation:
Alternative routing provides two different cables from the local exchange to your site, so you can protect against
cable failure as your service will be maintained on the alternative route.
Incorrect Answers:
B: With diverse routing, you can protect not only against cable failure but also against local exchange failure as
there are two separate routes from two exchanges to your site.
C: Lang-haul refers to circuits that span large distances, not between your site and the local exchange, such as
interstate or international.
D: Last mile circuit protection does not provide an extra connection.
