the MAC address of the IPv6 enabled interface

How many bits must be borrowed from the host portion of an address to accommodate a router with five connected networks?

three

What is the purpose of ICMP messages?

to provide feedback of IP packet transmissions

A user executes a traceroute over IPv6. At what point would a router in the path to the destination device drop the packet?

when the value of the Hop Limit field reaches zero

Match the subnetwork to a host address that would be included within the subnetwork. (Not all options are used.)

192.168.1.68 - 192.168.1.64/27 192.168.1.48 - 192.168.1.32/27 192.168.1.121 - 192.168.1.96/27

anycast

Three methods allow IPv6 and IPv4 to co-exist. Match each method with its description. (Not all options are used.)

dual stack - ipv4 packets and the ipv6 packets coexist in the same network. tunneling - The ipv6 packet is transported inside an IPv4 packet. translation - ipv6 packets are converted into ipv4 packets, and vice versa.

Refer to the exhibit. A company is deploying an IPv6 addressing scheme for its network. The company design document indicates that the subnet portion of the IPv6 addresses is used for the new hierarchical network design, with the s ite subsection to represent multiple geographical sites of the company, the s ub-site section to represent multiple campuses at each site, and the subnet section to indicate each network segment separated by routers. With such a scheme, what is the maximum number ofsubnets achieved per sub-site ?

16

A company has a network address of 192.168.1.64 with a subnet mask of 255.255.255.192. The company wants to create two subnetworks that would contain 10 hosts and 18 hosts respectively. Which two networks would achieve that? (Choose two.)

192.168.1.64/27 192.168.1.96/28

Which address is a valid IPv6 link-local unicast address?

A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia. The videoconferencing is conducted between two end devices through the Internet. The network administrator of school A configures the end device with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator knows immediately that this IP will not work. Why?

This is a private IP address.

Match each description with an appropriate IP address. (Not all options are used.)

a link local address - 169.254.1.5 a TEST-NET address - 192.0.2.123 an experimental address 240.2.6.255 a loopback address - 127.0.0.1
