Bulk Administration Tool: Updating Call Forwarding CSS in Cisco UCM
Short answer
D From Phones, select Add/Update Lines, and then click Update Lines.
Question
Key Takeaways
The exam tests the distinction between device-level and line-level bulk updates, with the common trap being confusion between general Phone updates and Line-specific updates.
This question tests knowledge of the specific menu navigation within the Bulk Administration Tool (BAT) for updating line-level settings like Calling Search Spaces. The community consensus confirms that 'Add/Update Lines' is the correct path to modify line attributes across multiple phones.
Common mistake: Option A is incorrect because there is no direct 'Update Lines' sub-menu under a standard 'Update Phones' action in BAT; users often assume they can update lines directly from the phone object without using the dedicated Line management interface.
Expert Analysis
Why the Answer Is Correct
Option D is correct because the Bulk Administration Tool provides a specific workflow for managing line-level configurations independently of phone device templates. To change a Calling Search Space (CSS) on a call forwarding feature, which is a line attribute, you must navigate to Phones > Add/Update Lines and then select Update Lines. This allows you to query existing lines and apply new settings en masse.
Why the Other Options Are Wrong
Option A is invalid because the BAT menu structure does not offer an 'Update Lines' button directly under the 'Update Phones' section; 'Update Phones' typically handles device-level parameters like skin files or SIP profiles. Option C is insufficient because selecting 'Query' only retrieves data for review or export; it does not provide the interface to modify and commit changes to the database. Option B is incorrect because while 'Lines' exists as a top-level category, the question specifically asks about actions taken from the context of configuring phones for users, and 'Add/Update Lines' under the Phones menu is the standard operational path for this task in many CUCM versions and exam contexts.
Community Comment Notes
Comment [1] highlights that Option A's menu choice does not exist and correctly identifies that device-level updates do not affect line-level settings. Comment [2] validates the exact menu path ('Bulk Administration --> Phones --> Add/Update Lines --> Update Lines') confirming the practical application in CUCM. Comment [3] incorrectly suggests C, but querying alone cannot block calls; configuration changes are required.
Exam Strategy
Memorize the distinct paths in the Bulk Administration Tool: use 'Phones > Add/Update Phones' for device settings and 'Phones > Add/Update Lines' for line settings. Always verify if the parameter you are changing belongs to the Device or the Line object.

Bazant 👍 3 Answered DA is wrong, such menu choice does not exist. Secondly Phones in bulk is updating device level settings not line level settings. D is the correct menu choice to update line level settings

Gary1968 👍 1 Answered CAnswer could possibly be C as the question mentions phones, not specifically lines and the steps are valid to update the CSS at the phone level.
