Frame-Relay lab for CCNA?

in CCNA & CCENT
Do we need to practice for a full out frame-relay setup lab for the CCNA 801 exam? Everyone on here seems to say either VTP, RIP, or OSPF, I havent heard anyone come on and say they got a frame-relay sim. Should I not worry about the frame-relay sim too much? I have everything else pretty much down, this is just a new thing that's been bugging me recently? Have the exam coming up pretty soon. Thanks.
