Which parameter would you tune to affect the selection of a static route as a backup, when a
dynamic protocol is also being used?

A.
hop count

B.
administrative distance

C.
link bandwidth

D.
link delay

E.
link cost

Explanation:
By default the administrative distance of a static route is 1, meaning it will be preferred over
all dynamic routing protocols. If you want to have the dynamic routing protocol used and
have the static route be used only as a backup, you need to increase the AD of the static
route so that it is higher than the dynamic routing protocol.
