How do you interpret an "interrogative word + non-polite form + か + 知る" construct?


Came across this sentence that has this "interrogative word + non-polite form
+ か + 知る" structure but not too sure if this is a kind of question or answer.

> どこの会議室か知りません。

Is this a question or an answer?

Am I right to assume that this sentence simply means:

> Do you know what kind of meeting room (is that)?




> どこの会議室か知りません。

Literally means "I don't know which meeting room it is."

> Do you know what kind of meeting room (that is)?

Would literally be (それが)どんな会議室か知っていますか。
