A. List Accounts, Use Accounts https://docs.cyberark.com/pam-self-hosted/13.0/en/Content/PASIMP/PSSO-PMSP.htm DR

I think this is a difficult question, but related to the "most likely use case scenario" - what I mean. In general, users will need List and Use permissions. And as for the secure connection https://docs.cyberark.com/privilege-cloud-shared-services/Latest/en/Content/PASIMP/Connecting-with-Secure-Connect.htm - this is only for Windows/Unix ad hoc connections, where List permissions are not necessary. So it will be the least permissions in this context, but not for all purposes. Assuming that the question is a general question, so it will be A. Because it was not specified for what purposes users need to connect and whether there is dual control or not. So a general question = a general answer.

You are in the PVWA - based on the question - so you need the List Account permission to choose the proper account. Use account is a must to use PSM.

C WITH SECURE CONNECT /RDP FILE

Answer is A.

Answer is A. You require the Use accounts and List accounts permissions in the Safe to connect transparently to remote machines. https://docs.cyberark.com/Product-Doc/OnlineHelp/PAS/13.0/en/Content/PASIMP/PSSO-PMSP.htm
