Answer the following questions to test your knowledge of this chapter:

1. What is backward compatibility?
   1. The ability to interact with newer versions of our app
   2. The ability to interact with older versions of our app
2. What is forward compatibility?
   1. The ability to interact with newer versions of our app
   2. The ability to interact with older versions of our app
3. Would there be any backward compatibility problem if, instead of changing the field type from uint32 to uint64, we were changing from uint64 to uint32?
   1. Yes, we might have an overflow
   2. No, all uint32 values are included in uint64
4. Would there be any forward compatibility problem if, instead of changing the field type from uint32 to uint64, we were changing from uint64 to uint32?
   1. Yes, we might have an overflow
   2. No, all uint32 values are included in uint64
5. What could potentially happen if we changed a field type from int32 to uint64 (hint: think in both forward and backward compatibility terms)?
   1. Negative values will be encoded...
