Juniper Exam JN0-1103 Topic 4 Question 7 Discussion

You are a network engineer at a large university. The architecture team has recently chosen Mist to replace the existing controller-based system and has replaced all the access points (APs) throughout the campus. Since the migration, users have been complaining about VoIP calls being dropped while moving between buildings. You have already validated that the APs provide appropriate coverage.

Which change would help alleviate this issue?
