Trending @Infosys; What do you do if you are constantly getting targeted by a manager

I am frequently getting targeted by a manger in meetings ( he is even not my manager ) . Every meeting he keeps on asking questions only to me, to which the answers are already there . He expects me to memorize things that are not even relevant to my work. I brought this to my manager notice and he is not intervening.What do you do in such case ?
