There isn't any specific job that a CCNP (or nearly any cert) covers. It is dependent on the employer, their equipment, and existing staff.
In many cases, the training never covered the kind of networking that they do.
For larger organizations, a cert of one kind or another, including college degrees, is a filter used by HR. Smaller organizations tend to assume that the training covers everything anyone would ever need to know about networking.
Reality is that you'll almost certainly be using a mix of equipment (Cisco, non-Cisco), new stuff integrated with old stuff (hence, experience increases the chance that you've seen the old stuff, Cisco or not), and essentially a static setup where the most common change is changing a port and the most common troubleshooting is 'I can't get on the network" (check the cable under the desk).
The next most popular question is "How can I get the experience?" and that's the tough one. Many churches/temples, charitable organizations, private schools are looking for and appreciate free or cheap assistance. You needs references; money is nice, but you usually don't get the money without the experience and references attesting to your quality work and attention to detail.
Depending on the hiring situation in your area, it may be better to hire in at any position, then try to move into the hands-on networking end of the company. Lots of folks start out in a call center / support center, for example. It's not unusual for call / support centers to have a Lab at their disposal, giving you some hardware to play with in your "copious free time" (i.e., rare spare time).
Good Luck
