Cisco UCM has 100,000 entries in the database learned through the ILS Service. Parameter ILS Max Number of Learned Objects in Database value is set to 100,000.
What will happen to learned data when the service parameter value is reduced to 50,000?
- A . Cisco UCM does not write additional ILS learned objects to the database and will delete the first 50,000 entries learned to keep it to the service parameter value.
- B . Cisco UCM does not write additional ILS learned objects to the database and will delete the last 50,000 entries learned to keep it to the service parameter value.
- C . Cisco UCM does not write additional ILS learned objects to the database and keeps the existing database entries.
- D . Cisco UCM will overwrite an entry for newly learned data and keep the parameter value at 100,000.
