QUESTION 1
What is the default interval at which Cisco 300-115 devices send Cisco Discovery Protocol advertisements?
A. 30 seconds
B. 60 seconds
C. 120 seconds
D. 300 seconds
Correct Answer: B Explanation

Explanation: Cisco Discovery Protocol is a Layer 2, media-independent, and network-independent protocol that networking applications use to learn about nearby, directly connected devices. Cisco 300-115 pdf Discovery Protocol is enabled by default. Each device configured for Cisco Discovery Protocol advertises at least one address at which the device can receive messages and sends periodic advertisements (messages) to the well-known multicast address 01:00:0C:CC:CC:CC. Devices discover each other by listening at that address. They also listen to messages to learn when interfaces on other devices are up or go down. Advertisements contain time-to-live information, which indicates the length of time a receiving device should hold Cisco Discovery Protocol information before discarding it. Advertisements supported and configured in Cisco 300-115 software are sent, by default, every 60 seconds.

QUESTION 2
Which statement about Cisco Discovery Protocol configuration on a Cisco switch is true?
A. CDP is enabled by default and can be disabled globally with the command no cdp run.
B. CDP is disabled by default and can be enabled globally with the command cdp enable.
C. CDP is enabled by default and can be disabled globally with the command no cdp enable.
D. CDP is disabled by default and can be enabled globally with the command cdp run.
Correct Answer: A Explanation

Explanation:
CDP is enabled on your router by default, which means the Cisco 300-115 dumps IOS software will receive CDP information. CDP also is enabled on supported interfaces by default. To disable CDP on an interface, use the “no cdp enable interface” configuration command. To disable it globally, use the “no cdp run” command.
