Given the age of the exam, if I am recalling correctly, it's UML 1.1. (The rest of the technologies on the Part I exam are based on J2EE 1.3, which includes EJB 1.1., and at the time, UML 1.1 was the standard. You can, however, use any general-released version of Java EE and UML for Part II.)

Yes, UML 1.1 is correct. I was reading UML Distilled by Martin Fowler and he says UML 1.1 had a feature allowed you to use commas (,) in the multiplicity of associations, and that this feature has been removed in UML 2.0. I also remember a question in the Whizlabs simulator which was addressing exactly that, a comma in a multiplicity.
