Test takers report two questions involving suspended practitioners.
Question 1 –
Specifically, the question asked where PTO is supposed to send an office action if the concerned patent attorney/agent is suspended. Answer – The USPTO will NOT correspond with suspended practitioners. Correspondence will be mailed to the applicant or another practitioner designated by the applicant.
MPEP 4.06 Attorney/Agent Suspended
The instant application contains a power of attorney to  who has been  from practice before the Patent and Trademark Office (Office). The Office does not communicate with attorneys or agents who have been suspended or excluded from practice. Accordingly, the Office action is being mailed to you as the inventor.
[4.06]Sole Practicioner/Sole Inventor – The Office action is to be mailed only to the inventor at his/her current address of record.
[4.07] Attorney/Agent Suspended (Sole Practitioner, Joint Inventors) – The Office action is to be mailed only to the inventor first named in the declaration at his or her current address of record.
[4.08] Attorney/Agent Suspended (Plural Practitioners) – The Office action is to be mailed both to the first named registered attorney or agent of record (who is not suspended or excluded) at the address currently listed in the Attorney’s Roster, and to the inventor first named in the declaration at his or her current address of record.
See also CFR 10.158 (2) Within 30 days of entry of the order of suspension or exclusion, surrender a client’s active Office case files to (i) the client or (ii) another practitioner designated by the client.
Question 2 –
There us a question on suspended practitioners. It is a “which one is incorrect” type of question. Know that the USPTO will not “ad litem” appoint a new practitioner if the one in the power of attorney is suspended (note: MPEP search for ad litem produces nothing). Ad litem is a term used in law to refer to a party appointed by a court to act in a lawsuit on behalf of another party—for instance, a child or an incapacitated adult—who is deemed incapable of representing (him/her)self.
