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?

Link-Local addresses are assigned automatically by the OS environment and are located in the block 169.254.0.0/16. The private addresses ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. TEST-NET addresses belong to the range 192.0.2.0/24. The addresses in the block 240.0.0.0 to 255.255.255.254 are reserved as experimental addresses. Loopback addresses belong to the block 127.0.0.0/8.

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

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? (Choose three.)

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? (Choose three.)

loopback link-local

What are two types of IPv6 unicast addresses? (Choose two.)

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?

172.16.4.4 192.168.5.5 10.1.1.1

Which three IP addresses are private ? (Choose three.)

dual stack tunneling

Which two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains? (Choose two.)

network portion host portion

Which two parts are components of an IPv4 address? (Choose two.)

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? (Choose two.)
