What is a use of Cisco Discovery Protocol? to determine the platform version of the neighboring Cisco devices to display information about the routing protocol to display the MAC address and ARP information to share information about non-Cisco equipment, such as the operating system version and IPv4 address

to determine the platform version of the neighboring Cisco devices

If POST completes during a startup of a Cisco device and there is no configuration file, what does the router do? It reboots. It initiates initial configuration through "setup." It creates a configuration file with default settings and boots that file. It shuts down the router.

It initiates initial configuration through "setup."

What are four problems with IPv4 addressing workarounds? (Choose four.) NAT breaks the end-to-end model of IP. DHCP breaks the end-to-end model of IP. NAT inhibits end-to-end network security. VLSM inhibits end-to-end network security. Some applications are not NAT-friendly. Some applications are NAT-friendly. The merging of private networks is difficult if overlapping IPv4 address ranges are used.

Which three mechanisms are used to extend the lifetime and usefulness of IPv4? (Choose three.) CIDR VLSM NAT DNS IPv5 IPv6

CIDR – reduces routing table size and conserves address space VLSM – allows variable-length subnet masks to use IP addresses more efficiently NAT – allows multiple hosts to share a single public IPv4 address
