directed broadcast
A message is sent to all hosts on a remote network. Which type of message is it?
when the value in the TTL field reaches zero
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?
stateless DHCPv6
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?
32
How many bits are in an IPv4 address?
169.254.1.5 -> a link-local address 192.0.2.123 -> a TEST-NET address 240.2.6.255 -> an experimental address 172.19.20.5 -> a private address 127.0.0.1 -> a loopback address
Match each description with an appropriate IP address.
11101000
The binary equivalent of the decimal number 232 is ...?
149
The decimal equivalent of the binary number 10010101 is ...?
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.
What are three characteristics of multicast transmission?
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 parts of an IPv6 global unicast address?
loopback link-local
What are two types of IPv6 unicast addresses?
host address
What does the IP address 172.17.4.250/24 represent?
Hop Limit field
What field content is used by ICMPv6 to determine that a packet has expired?
IP is properly installed on the host
What is indicated by a successful ping to the ::1 IPv6 address?
63
What is the decimal equivalent of the hex number 0x3F?
to provide feedback of IP packet transmissions
What is the purpose of ICMP messages?
to determine the subnet to which the host belongs
What is the purpose of the subnet mask in conjunction with an IP address?
255.255.240.0
What subnet mask is represented by the slash notation /20?
link-local
What type of address is automatically assigned to an interface when IPv6 is enabled on that interface?
3FFE : 1044 : 0 : 0 : AB :: 57
Which of these addresses is the shortest abbreviation for the IP address: 3FFE : 1044 : 0000 : 0000 : 00AB : 0000 : 0000 : 0057?
ICMPv6
Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?
10.1.1.1 172.16.4.4 192.168.5.5
Which three IP addresses are private ?
dual stack tunneling
Which two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains?
network portion host portion
Which two parts are components of an IPv4 address?
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
Which two things can be determined by using the ping command?
