Which of the following statements is false about WIDS/WIPS?

After air scan is enabled, you are advised to use an independent radio for air scan if latency-sensitive services, such as video conferencing, are running on the network.

If WIDS is configured on an AP radio, the radio cannot be used to set up a WDS bridge or mesh link.

In HSB scenarios, WIDS entries on the active WAC can be backed up to the standby WAC

When an AP works in normal mode, the delay may increase instantaneously during the radio scan period.
