It’s unlikely. The Reading 5 GIPS LOS states:
The candidate should be able to:
a. describe the key features of the GIPS standards and the fundamentals of compliance;
b. describe the scope of the GIPS standards with respect to an investment firm’s definition and historical performance record;
c. explain how the GIPS standards are implemented in countries with existing standards for performance reporting and describe the appropriate response when the GIPS standards and local regulations conflict;
d. describe the nine major sections of the GIPS standards.
The GIPS glossary is complementary to that the LOS but the LOS does not state you need to memorize the glossary nor appendix. As you go through the CFA exam curriculum a lot of the terms would start to get familiar.
I would recommend scanning them all but not spending crazy amounts of time to deep-dive into each term, and skim them again during review time.
