What are three parts of an IPv6 global unicast address?

A global routing prefix that is used to identify the network portion of the address that has been provided by an ISP. A subnet ID that is used to identify networks inside of the local enterprise site. 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. The range of 224.0.0.0 to 224.0.0.255 is reserved to reach multicast groups on a local network.

A message is sent to all host on a remote network. Which type of message is it?

Directed Broadcast

Which two IPv4 to IPv6 transition techniques manage the interconnection of the IPv6 domains?

Dual Stack and Tunneling

What field content is used by ICMPv6 to determine that a packet had expired?

Hop Limit Field

What does the IP address 172.17.4.250/24 represent?

Host Address

Which protocol supports Stateless Address Autoconfiguration (SLAAC) 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

What type of address is automatically assigned to an interface when IPv6 Is enabled on that interface?

Link-Local

Match each description with an appropriate IP address

Link-Local Address: 169.254.1.5 TEST-NET Address: 192.0.2.123 Experimental Address: 240.2.6.255 Private Address: 172.19.20.5 Loopback Address: 127.0.0.1

What are two types of IPv6 unicast addresses?

Loopback and Link-Local

Which two ports are components of an IPv4 address?

Network and Host portion

An administrator wants to configure host to automatically assign IPv6 addresses to themselves by the use of Router Advertisement messages, but also to obtain the DNS server address from the 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 return to the source. The destination device is reachable through the network.

What is the purpose of the subnet mask in conjunction with an IP address

To determine the subnet to which the host belongs

What is the purpose of ICMP messages?

To provide feedback of IP packet transmissions

A user is executing a tracert 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
