The Cisco Unified ICM call routing script can access an external database for routing or CTI data.
In this script, the DB Lookup node is used to access a CustDB to look up the customer by the
caller entered digits associated with the call.

What will this script do if the caller entered digits are invalid?

A.
The DB Lookup node will be ignored and pass control to the Select node, with the database
values left empty because the value was invalid.

B.
The DB Lookup node will fail and the SET node will be used to set Call Variable 2 to “Customer
Not Found”.

C.
The DB Lookup node will find the first row in the table, which is set to have the customer name
as “INVALID DATA”.

D.
The DB Lookup node will fail and the SET node will be used to set Call Variable 2 to “Customer
Not Found,” but only if the Call Variable 2 is not already set for this call.
