There can be various NAT scenarios which can create issues in the exam. Lets take a static NAT case which appear very simple at first but it requires some thought in order to solve it.
R6(f0/0.146)----(f0/1)R4(s0/0/1)----(s0/0/1)R5(s0/0/0)----503FRSW305----(s1/0)R3(f0/0)-----(f0/3)SW1
R5 is the NAT device and ospf is running between all devices. Loopbacks of R6 and SW1 are not advertise in ospf. Now the task is configure this scenario so that R6 can ping SW1's loopback sourced from its loopback. Use minimum number of static routes to solve this.
Note : Try to solve it without looking at the solution.
Here is the solution..
