Which configuration file does a Cisco IP phone with MAC address 1111.2222.3333 request from the TFTP server when an Initial Trust List file is present?
Click on the arrows to vote for the correct answerA. B. C. D. E.
When a Cisco IP phone requests its configuration file from the TFTP server, it sends its MAC address as part of the request. The TFTP server uses this MAC address to identify the specific phone and provide it with the appropriate configuration file.
When an Initial Trust List (ITL) file is present on the phone, it indicates that the phone has already been configured to trust certain certificates. In this case, the phone will request the configuration file with a specific name that includes its MAC address and the extension .cnf.xml.
Therefore, the correct answer to the question is A. SEP111122223333.cnf.xml.
The other answer choices are as follows:
B. SEP111122223333.cnf - This file would be requested if the phone did not have an ITL file present. C. SEP111122223333.cnf.xml.sgn - This file would be requested if the phone had an ITL file present and was configured to use signed configuration files. D. SEPDefault.cnf.xml.sgn - This file would be requested if the phone was unable to obtain its specific configuration file for any reason. E. SEP111122223333.cnf.xml.enc.sgn - This file would be requested if the phone was configured to use encrypted configuration files.
