I am running into difference between study material and practice questions as follows:

Hash Partitiion, was it introduced in oracle 8i or 9i ... practice question picks 9i?

When storing the time zone displacement (or offset) does it require extra bytes ... study material says yes, practice question says no?

You maintain a primary and standby database. You want to configure your system for no-data-loss. No data divergence is acceptable.

Which data availability mode should you use?

A. Rapid protection
B. Instance protection
C. Delayed protection
D. Guaranteed protection

My anwser was B. selftest was D.
