問題文
Application-aware path selection is deployed at every branch. Voice quality is good everywhere except at one small branch, where the reports show the feature as having nothing to act on. What is the situation there?
選択肢
- That branch has only one usable transport, so there is no alternative path to move the traffic onto and the capability cannot improve the outcome by itself.
- That branch is running an older version of the branch software, so the measurements it takes are not comparable with those of the other branches and the feature therefore declines to act on them until the versions across the estate have been brought into line with each other.
- The voice application is not identified at that branch, which the reports would show as a different application name for sessions that look the same elsewhere.
- The thresholds at that branch are set more tolerantly than they are elsewhere, so the measurements never cross them and no move of the traffic is ever triggered.
