1.

D

Translation patterns are defined to provide a "translation of last resort." CallManager processes them just before it routes a call. After the translation pattern has modified the dialed digits, CallManager sends the transformed digits through digit analysis again.

2.

C

The DN 0111 passes through the right-justified X wildcards. The result is that the CallManager prepends the 972555 to the 0111 and sends 9725550111 as the CLID information.

3.

B

The predot digit discard instructions remove all dialed digits before the period.

4.

A

You must apply the route filter to either a route pattern or a translation pattern for it to take effect. After you have applied it to a route pattern, you must select either Route This Pattern or Block This Pattern to define the allow or deny action.

   
5.

A

The 11D@10D digit discard instruction takes an 11-digit long-distance number and converts it to a 10-digit number. This is typically used for toll-bypass purposes.

6.

D

Applying a calling-party transformation mask of 8 causes all caller ID information to be replaced and become just the digit 8. To prefix an 8 using a transformation mask, wildcard digits (X) would be necessary.

7.

B

Called-party transformation masks always transform the dialed-number information.

8.

D

The order of application of digit translation applies the transformation mask before the prefix digits, causing the resulting caller ID to display as 5555123.

9.

D

In this case, you have created a routing loop within the CallManager. The route pattern prefixes an 8 to the 4xxx dialed numbers and the translation pattern strips the 8 and returns the digits to the CallManager for processing. The call will loop ten times through the CallManager route plan and then return a fast busy signal.

10.

B

Calling-party transformations change caller ID information, whereas called-party transformations change dialed-number information.
