A and D

Modern Cisco IP Phones support the G.711 (64 Kbps) and G.729 (8 Kbps) codecs. The old Cisco IP Phones acquired directly from Selsius supported the G.711 and G.723 (6.3 Kbps) codecs.

   
2.

A and D

Because Cisco was one of the first companies to market with IP Phone technology, the Power over Ethernet (PoE) standard was not fully developed. Because of this, Cisco created its own, prestandard inline power. In modern times, the IEEE has solidified the 802.3af inline power standard. The Cisco IP Phone 7961G supports both of these inline power standards.

3.

B, C, and E

The Cisco IP Phone 7905 and Cisco ATA 186 do not have built-in Ethernet switches; rather, they terminate a 10BASE-T Ethernet connection. The Cisco IP Phone 7912 is exactly the same as the 7905 but supplies the built-in 10/100 Ethernet switch. The same is true of the Cisco ATA 188.

C

The Cisco 7980 is the only IP Phone that provides built-in video-processing capabilities.

5.

A, C, D, and B

When the IP Phone goes through the boot process, it initially obtains inline power using the Cisco prestandard or IEEE 802.3af. From there, it loads its built-in firmware image, which directs it to receive VLAN information through CDP. After it has a VLAN assignment, it broadcasts for a DHCP address, which also contains the TFTP server hostname or address. It then contacts the TFTP server to download its configuration file.

DHCP Option 150 is used to deliver the IP address of a TFTP server to a Cisco IP Phone. DHCP Option 66 is used to deliver the hostname of a TFTP server to a Cisco IP Phone.

7.

A

Most Cisco IP Phones (all except the 7902G) support XML processing, which is an industry standard for storing data with processing and formatting options.

8.

A and D

The Cisco IP Phone 7961 supports both the Cisco prestandard and 802.3af inline power, whereas the 7960 supports only the Cisco prestandard. In addition, the Cisco 7961 IP Phone adds support for Gigabit Ethernet connections.

9.

C

The Cisco ATA 188 provides two Foreign Exchange Station (FXS) ports that allow you to convert up to two analog devices into VoIP devices.

   
10.

A

The Cisco IP Phone 7902G is the most cost-effective, single-line IP Phone available from Cisco. It is the only IP Phone not equipped with a display screen, so the features are limited to that of a standard analog-style device.
