How many bits are in an IPv4 address?
32
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
Stateless DHCPv6
Allows clients to use ICMP Router Advertisement messages to automatically assign IP addresses to themselves
A message is sent to all hosts on a remote network. Which type of message is it?
Directed broadcast
SLAAC
Does not allow the client to obtain additional information through DHCPv6
Which two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains?
Dual stack Tunneling
What field content is used by ICMPv6 to determine that a packet has expired?
Hop Limit Field
What is indicated by a successful ping to the ::1 IPv6 Address?
IP is properly installed on the host This is the loopback address
What type of address is automatically assigned to an interface when IPv6 is enabled on that interface?
Link-local
What are two types of IPv6 Unicast addresses?
Link-local Loopback
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
What is the purpose of the subnet mask in conjuction with an IP address
To determine the subnet to which the host belongs
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 becomes 0
Loopback addresses
127.0.0.0/8
What subnet mask is represented by the slash notation /20
255.255.240.0
What are three part of an IPv6 global unicast address?
An interface ID that is used to identify the local host on the network A subnet ID that is used to identify networks inside of the local enterprise site A global routing prefix that is used to identify the portion of the network address provided by a local admin
Link-local addresses
Assigned automatically by the OS environment Located in the block 169.254.0.0/16
What does the IP address 172.17.4.250 represent?
Host address
Which two parts are components of an IPv4 address?
Host portion Network portion
Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?
ICMPv6
What is the purpose of ICMP messages?
To provide feedback of IP packet transmissions
