Which of the following technologies can be used to establish a federated data architecture capable of exposing standardized data models while abstracting disparate data sources? Select the correct answer.
Hmm, this is a tough one. I'm thinking D. WS-Federation, but I might need to do a quick search on 'federated data architecture' to make sure I'm not missing something obvious. Gotta love these tricky certification questions!
D. WS-Federation, for sure. It's designed specifically for federated identity management, which seems relevant here. Although, I do wonder if it's the only option that can 'abstract disparate data sources'.
Hmm, I'm not sure about this one. I was thinking B. XQuery, but I guess that's more for querying XML data rather than establishing a federated architecture.
I think the answer is D. WS-Federation seems to be the best option for a federated data architecture that can expose standardized data models while abstracting disparate data sources.
