Kosovo as the UN Security Council record has it, and as Serbia's Constitution describes it

UN Security Council resolution 1244 (1999) was adopted by 14 votes to none, with China abstaining.
It authorised international civil and security presences in Kosovo under United Nations auspices and an interim administration.
It reaffirmed the sovereignty and territorial integrity of the Federal Republic of Yugoslavia and called for substantial autonomy for Kosovo.
Serbia's Constitution says Kosovo and Metohija is an integral part of Serbia's territory with the status of substantial autonomy.
Article 182 names two autonomous provinces: Vojvodina, and Kosovo and Metohija.

Resolution: 1244 (1999) Vote in the Security Council: 14 in favour, none against, 1 abstention (China) Autonomous provinces in Serbia's Constitution: 2: Vojvodina, and Kosovo and Metohija
Why it matters for exams: Kosovo's status is a recurring question in Balkan affairs; the exact wording of the UN resolution and of Serbia's Constitution is what is asked.
