Sandy,

Yes, ip route x.x.x.x y.y.y.y null0 is a static route.

Can you use this on the CCIE lab exam, maybe. Does it best fit the
instructions of the challenge you have been presented with? If, yes, then
yes, you can use it. The lab has two objectives, one to exercise your
knowledge of routing and theCisco IOS, and two, to evaluate your judgement.
Based on your knowledge and judgement, if this is the best solution, it will
be acceptable in the lab. In most cases, static routes are not the best
choice, but under some circumstances, they do represent a powerful solution.
Of course, if the lab instructions state "Create a static route to X.X.X.X
via null0 and redistribute it in OSPF", I'd do it.
