What are three parts of an IPv6 global unicast address?
1.)A global routing prefix that is used to identify the network portion of the address that has been provided by an ISP 2.) A subnet ID that is used to identify networks inside of the local enterprise site 3.) An interface ID that is used to identify the local host on the network

What are three characteristics of multicast transmission?
A single packet can be sent to a group of hosts Multicast transmission can be used by routers to exchange routing information
Which two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains?
Dual Stack: Allows IPv4 and Ipv6 to coexist on the same network segment Tunneling : method of transporting an IPv6 over an IPv4 network
What field content is used ICMPv6 to determine that a packet has expired
Hop Limit field
What does the IP address 172.17.4.250/24 represent?
Host address
Which protocol supports Stateless Address Autoconfiguration (SLACC) for dynamic assignment of IPv6 addresses to a host?
ICMPv6
What is indicated by a successful ping to the ::1 IPv6 address?
IP is properly installed on the host
An administrator wants to configure hosts to automatically assign IPv6 addresses to themselves by the use of Router Advertisement messages, but also to obtain the DNS server address from a DHCPv6 server. Which address assignment method should be configured?
Stateless DHCPv6
Which two things can be determined by using the ping command?
The average time it takes a packet to reach the destination and for the response to the source The destination device is reachable through the network
What is the purpose of ICMP messages
To provide feedback of IP packet transmissions
A user is executing a trecert to a remote device. At what point would a router, which is in the path to the destination device, stop forwarding the packet?
When the value in the TTL field reaches zero
A message is sent to all hosts on a remote network. Which type of message is it?
directed broadcast
What type of address is automatically assigned to an interface when IPv6 is enabled on that interface?
link-local
What are two tyes of IPv6 unicast addresses?
loopback link-local
Which two parts are components of an IPv4 address?
network portion host portion
What is the purpose of the subnet mask in conjunction with an IP address?
to determine the subnet to which the host belongs
