In a WLAN network with the WIDS function enabled, which of the following statements about device information reporting are incorrect? (Multiple choice)

Question

Options

• ADevice information reporting, short-period reporting is also called immediate reporting period
• BThe long period of equipment information reporting can be set, the minimum is 1 hour
• CThe short-term reporting is full reporting
• DThe default time for long-term reporting is 5 hours

• A
  23% (5)
• B
  77% (17)

Explanation

Options B, C, and D each contain factual errors about how WIDS device information reporting works. Option B is incorrect because the long-period reporting interval can be configured, but the minimum value is not 1 hour - the actual configurable minimum is lower than that, making the stated threshold wrong. Option C is incorrect because short-period (immediate) reporting is incremental reporting, meaning only new or changed information is sent; it is the long-period report that performs full reporting of all device data. Option D is incorrect because the default long-period reporting interval is not 5 hours - the standard default is 24 hours.

Option A is the only correct statement: short-period reporting is indeed also referred to as immediate reporting, which is why it stands alone as the right choice.

Memory tip: Think of it as short equals fast and partial (incremental only), while long equals slow and complete (full report). The long period defaults to a full day (24 hours), not 5 hours, and its minimum threshold is shorter than 1 hour.
