/summon minecraft:zombie ~ ~ ~ {ArmorItems:[{id:"minecraft:diamond_boots",Count:1},{id:"minecraft:diamond_leggings",Count:1},{id:"minecraft:diamond_chestplate",Count:1},{id:"minecraft:diamond_helmet",Count:1}]}Try to remove the armour with
/data remove entity @e[type=minecraft:zombie,sort=nearest,limit=1] ArmorItemsand see that it does not work.
