As others have said, you'll probably be asked to plan and start a XC, at least to the first led. A good examiner will then present you with a situation where you have to deviate. It's then up to you to figure out where you can go and land there. A really tricky examiner will "fail" the engine in the pattern when you're going to the diversion. It's a very realistic scenario - engine starts running rough, you need to set down quickly, engine stops before you land.
