The answers are different for each line.

In prefix compression, does the entire prefix stored in the header need to match the data to be used?

No

if I have a prefix of "aaabcd" in the header and a data element of "aaabfgr" in a field, can prefix compression be applied?

Yes..

I choose No, and it gave incorrect....:hehe:

Same here - I answered the first question as a no.:rolleyes:
