A Storage Administrator Has Created a VPLEX Distributed Device

A storage administrator has created a VPLEX distributed device. The administrator is performing application tests on the host utilizing the distributed virtual volumes. During testing, some of the write response times appear to be elongated. What is a characteristic of distributed devices that explains this issue?

A) Writes need to be written locally to multiple VPLEX Directors before sending a host acknowledgement.
B) Writes need to be written to both clusters before sending a host acknowledgement.
C) Writes need to be journaled in the VPLEX Witness logging volumes before sending a host acknowledgement.
D) Writes need to be protected on the remote disk arrays only before sending a host acknowledgement.
