- Cisco Unified Communications Manager Express Overview: This section gives an overview of the Cisco Unified Communications Manager Express (CME) system, the Cisco hardware it can run on, and features it supports.
- Licensing and Models for Cisco Unified CME: As you design your IP telephony network, you can choose a key system, PBX, or hybrid model. This section discusses these models and the licenses required by Cisco to operate a Cisco Unified CME environment.
- Installing Unified CME on a Cisco Router: Many routers ship with Cisco Unified CME software preinstalled; on others, it must be installed manually. This section discusses the installation and upgrade process for Cisco Unified CME.
- Configuring the Cisco Unified CME Router as a TFTP Server: The Cisco Unified CME router is responsible for serving the correct files to the IP phones during the boot process. This section discusses the configuration of the CME router as a TFTP server.
- Configuring the Cisco Unified CME System-Level Functions: In this section, you will see four steps you must take to prepare the Cisco Unified CME router to handle Cisco IP phones.
At this point, you now understand the difference between TDM and IP-based voice systems. You have seen the foundation network requirements for Power over Ethernet (PoE), Dynamic Host Configuration Protocol (DHCP), virtual LANs (VLANs), and Network Translation Protocol (NTP) and understand the configuration required to build the infrastructure. Now it is time to turn the attention to the Cisco Unified Communications Manager Express (CME) installation process.

- 24
- 50
- 144
Which of the following are required licenses to operate a Cisco Unified CME router? (Choose three.)
- IOS license
- User license
- Phone license
- Phone user license
- Feature license
Which design model would you use if you wanted the number of lines on each IP phone to match the number of phone lines coming in from the PSTN?
- Shared line model
- Limited model
- Keyswitch model
- Hybrid model
- PBX model
What command can you use to extract a bundle of CME files into the flash of the router?
- copy
- extract
- xtract
- archive
Which files does the Cisco IP phone download from the TFTP server during the boot process? (Choose two.)
- Firmware
- Music on Hold
- XML templates
- Configuration files
What is the primary function of the alias syntax in the tftp-server command?
- To make files in subdirectories accessible without entering the full path
- To rename files
- To hide the original filename to increase network security
- To allow multiple files to be accessed through one filename
Once phone firmware files are downloaded and copied to the flash memory of a router, how are they made accessible to the IP phones?
- The CME telephony service automatically recognizes these files and makes them available via TFTP.
- The firmware files must be manually made available by using the tftp-server command.
- The firmware files are made available through TFTP when entered in the telephony service using the load command.
- The firmware files are copied to an external TFTP server by the router and downloaded directly to the IP phones.
Which three commands must be entered to allow the CME router to begin accepting IP phone registrations?
- max-ephones
- max-dn
- no shutdown
- ip source-address
- telephony-service enable
- no telephony-service disable
How does the Cisco Unified CME router create configuration files for the Cisco IP phones? (Choose two.)
- Configuration files are automatically created as configuration information is entered.
- Configuration files must be downloaded from Cisco and copied to the flash of the router.
- Configuration files can be generated by entering the create cnf-file syntax.
- Configuration files are generated by the IP phones and uploaded to the router’s flash during the boot process.
The Cisco Unified CME router generates a generic configuration file for IP phones that do not have any configuration information. What is the name of this file?
- Config.default
- Default.xml
- Default.cnf
- XMLDefault.cnf.xml
- Holiday prompt
- Emergency prompt
