Quiz

1. Why is it not always more optimal to use varint for integer types?
   1. No reason, they are always more optimal than fixed integers
   2. varint encoding serializes bigger numbers into a bigger amount of bytes
   3. varint encoding serializes smaller numbers into a bigger amount of bytes
2. How can we get the number of bytes a message will be serialized into?
   1. proto.Marshal + len
   2. proto.UnMarshal + len
   3. len
3. What kind of tag should we give to fields that are often populated?
   1. Bigger tags
   2. Smaller tags
4. What is the main problem of splitting messages to use smaller tags?
   1. We have overhead because sub-messages are serialized as length-delimited types
   2. No problem – this is the way to go
5. What is FieldMask?
   1. A collection of fields’ paths telling us what data to exclude
   2. A collection of fields’ paths telling us what data to include
6. When is a repeated field serialized as unpacked?
   1. When repeated fields are acting on scalar types
   2. Only when we use the packed option with the value false
   3. When...
