When we talk about doing an ILS .... a standard ILS .... we are basically talking about a CAT I ILS .... which gets us down to a minimum of 200ft DH, 550m RVR. On the JAA mins charts (10-9X) this is normally the top line of figures ... In the exam if the questions simply ask for the minimum for an 'ILS' approach - they mean CAT I ILS.

In the JEPP MANUAL thee are a few CAT II ILS charts .... a CAT II ILS will get you down to a minimum of RA 100 ft DH (Rad ALT), 300m RVR. For a CAT II approach (or CAT III - but there aren't any charts) you ONLY need the RAD ALT figure, however, they still give you the DA (QNH) and DH (QFE) numbers as information only.
