Question 2
Which two statements about CDP are true? (Choose two)
A. It can be disabled only at the interface level.
B. Devices with Cisco Discovery Protocol configured send advertisement messages to a multicast address on a periodic basis.
C. It is disabled when switches have mismatched native VLANs.
D. Devices with Cisco Discovery Protocol configured send advertisement messages to a broadcast address on a periodic basis.
E. VTP relies on Cisco Discovery Protocol to carry VTP domain information.
Answer: B E
Question 3
Which three pieces of information about the remote device are reported by Cisco Discovery Protocol? (Choose three)
A. The routing protocols in use on the device
B. Its spanning-tree state
C. Its hostname
D. Its port number
E. Its configuration register value
F. Its hardware platform
Answer: C D F
Explanation
The information contained in Cisco Discovery Protocol advertisements varies based on the type of device and the installed version of the operating system. Some of the information that Cisco Discovery Protocol can learn includes:
+ Cisco IOS version running on Cisco devices
+ Hardware platform of devices
+ IP addresses of interfaces on devices
+ Locally connected devices advertising Cisco Discovery Protocol
+ Interfaces active on Cisco devices, including encapsulation type
+ Hostname
+ Duplex setting
+ VLAN Trunking Protocol (VTP) domain
+ Native VLAN
Type-Length-Value (TLV) fields are blocks of information embedded in Cisco Discovery Protocol advertisements. Information in advertisements varies, and the TLV frame format allows for extending advertisements when needed.
CDPv2 advertises IP Network Prefix TLV contains a list of network prefixes to which a sending device can forward IP packets. A prefix includes the interface protocol and the port number. For example, Ethernet 1/0.
