Answer 1

New Table = 
DISTINCT(
    UNION(
        SELECTCOLUMNS(Table1, "a", Table1[Column A]),
        SELECTCOLUMNS(Table2, "a", Table2[Column_B])
    )
)

Answer 2

You have to create a New Table using the following DAX expression:

New Table = DISTINCT(UNION('Table1', 'Table2'))

Answer 3

This should be done in Power Query unless you also need to load the two source tables in your model. EG

let
    #"Appended Query" = Table.Combine({#"Table1", #"Table2"}),
    #"Removed Duplicates" = Table.Distinct(#"Appended Query")
in
    #"Removed Duplicates"
