You recently noticed that when devices send large numbers of CDP neighbor announcements, some devices are crashing. You decide to disable CDP on the router.  \n[https://www.gratisexam.com/](https://www.gratisexam.com/)  \nWhich command should you use to achieve the objective?  \nA. no cdp run  \nB. set cdp disable  \nC. no cdp enable  \nD. no cdp advertise-v2  \nCorrect Answer: A  \nSection: (none)  \nExplanation  \nExplanation/Reference:  \nExplanation:  \nYou should use the no cdp run command to disable CDP on the router. Due to a known vulnerability regarding the handling of CDP by Cisco routers and switches when devices send large numbers of CDP neighbor announcements, some devices can crash or cause abnormal system behavior. To overcome this problem, you can disable CDP for the entire router by using the no cdp run command.  \nYou cannot use the set cdp disable command to disable CDP on the router. This command disables CDP on an entire Catalyst switch.  \nYou cannot use the no cdp enable command to disable CDP on the router. This command disables CDP on a specific interface.  \nYou cannot use the no cdp advertise-v2 command to disable CDP on the router. This command disables CDPv2 advertisements.  \nObjective:  \nLAN Switching Fundamentals Sub-Objective:  \nConfigure and verify Layer 2 protocols  \nReferences:  \n[https://www.gratisexam.com/](https://www.gratisexam.com/)  \nCisco > Support > Using Cisco Discovery Protocol  \nCisco > Support > Technology Support > Network Management > Cisco's Response to the CDP Issue > Document ID: 13621  \nQUESTION 2  \nWhich is NOT a valid range for private IP addresses?  \nA.

IANA also performs DNS root zone management. IANA operates with the help of International Engineering Task Force (IETF) and RFC Editor to manage IP address allocation and DNS root zone management. There are Regional Internet Registries (RIRs) through which IANA allocates local registrations of IP addresses to different regions of the world. Each RIR handles a specific region of the world.  \nObjective:  \nNetwork Fundamentals Sub-Objective:  \nDescribe the need for private IPv4 addressing  \nReferences:  \n[http://www.ietf.org/rfc/rfc1918.txt](http://www.ietf.org/rfc/rfc1918.txt)  \n[http://www.iana.org/](http://www.iana.org/)  \nQUESTION 3  \nWhich of the following protocols allow the root switch location to be optimized per VLAN?
