this one ->

according to cisco learning materials from topic 9.3.0 , correct answer forquestion : "Which two ICMPv6 messages are used during the Ethernet MAC address resolution process? (Choose two.)" should be : neighbor solicitation and neighbor advertisement ,but when i mark them there is an error and quiz accept only answers : neightbour advertisement and router solicitation as correct, which arent.

i check it triple duble because i thought i overlook something but no. You have an error here !

You might give me some extra credits now as reward for an good eye
