Real estate salesperson exam question. PLEASE HELP

[Charles Coaston]

I have a few questions that were on my  real estate exam that didn't make sense to me.

1. If the agent leaves the brokerage that he works for can his/her listings follow? 

2. If the agent list a house under exclusive agent how will the agent handle selling the house since his/her  not guaranteed a commission when the house sells by the seller

3. A property manager would need a real estate agent in what circumstance?

4. How can a agent earn a bonus? From his broker? From the other broker for making a sale? One of the question was "The agent worked hard so the broker decided to give him a commission is he/she able to except it?"

5. If the agent has no listing contract, what can the agent do with the client? how can they show the home without a listing contract? Can the agent show the house with notice of the seller?
