In MZ's and Ivan's notes, they say SOA supports UDDI and dynamic discovery of service registry (I think this registry refers to JAXR).
However, JAXR and UDDI are obsolete.
So, in the exam, should I select options like SOA supports UDDI or SOA supports dynamic discovery of services ?

While I'm not familiar with the exam, saying "SOA supports UDDI" or "SOA supports dynamic discovery of services" sounds wrong to me. SOA is an architectural concept; any given implementation might or might not support particular features (like service discovery) or protocols (like UDDI).

[sarcasm] Shhh !! Don't tell OASIS that their UDDI standard is obsolete. They keep thinking its not ! [/sarcasm]

What makes you think UDDI is obsolete ? Whomever told you that doesn't know what they are saying.

I heard my web service instructor said UDDI is obsolete. But I never verify if that is true or not.
Please don't take it too personal about that.

In the version 6 of the exam, most ranchers said JAXR and UDDI won't be in the exam objective anymore.

From MZ's notes, he put "Both web service and SOA can use UDDI.
I don't know if I should still worry about anything related to UDDI.

I believe UDDI/JAXR is still on the exam, so in that sense you should worry about it. They're obsolete in the sense that almost nobody outside of large companies uses them, and even inside of large companies use is rare. The public UDDI repositories have ceased to exist a long time ago.

While it may be true that usage has dwindled, use of the UDDI standard is not as catastrophic as suggested. In fact, Apache jUDDI framework is actively being developed, the last release just a few days ago (jUDDI Release 3.2.0). UDDI is morphing and the early implementations are certainly not around any longer. Today, UDDI is a metadata management standard for SOA.

UDDI/JAXR is not on the EE6 exam. Just read the definitions what they are about and that should be enough.
