Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host? ARPv6 DHCPv6 ICMPv6 UDP
ICMPv6
What are three parts of an IPv6 global unicast address? (Choose three.) an interface ID that is used to identify the local host on the network an interface ID that is used to identify the local network for a particular host 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 network portion of the address that has been provided by an ISP a global routing prefix that is used to identify the portion of the network address provided by a local administrator
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 network portion of the address that has been provided by an ISP*
A message is sent to all hosts on a remote network. Which type of message is it? unicast directed broadcast limited broadcast multicast
directed broadcast*
Which two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains? (Choose two.) trunking dual stack encapsulation tunneling multiplexing
dual stack tunneling
What type of address is automatically assigned to an interface when IPv6 is enabled on that interface? global unicast link-local loopback unique local
link-local
What are two types of IPv6 unicast addresses? (Choose two.) anycast link-local multicast loopback broadcast
link-local loopback
Which two parts are components of an IPv4 address? (Choose two.) logical portion network portion physical portion broadcast portion host portion subnet portion
network portion host portion
Which two ICMP messages are used by both IPv4 and IPv6 protocols? (Choose two.) router solicitation protocol unreachable neighbor solicitation route redirection router advertisement
protocol unreachable route redirection
When an IPv6 enabled host needs to discover the MAC address of an intended IPv6 destination, which destination address is used by the source host in the NS message? global unicast address of the receiver solicited-node multicast address all-node multicast address link-local address of the receive
solicited-node multicast address
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? SLAAC stateless DHCPv6 stateful DHCPv6 RA and EUI-64
stateless DHCPv6
How many bits must be borrowed from the host portion of an address to accommodate a router with five connected networks? two three four five
three
What is the purpose of ICMP messages? to inform routers about network topology changes to ensure the delivery of an IP packet to provide feedback of IP packet transmissions to monitor the process of a domain name to IP address resolution
to provide feedback of IP packet transmissions
Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures? encapsulation translation dual-stack tunneling
tunneling
When will a router drop a traceroute packet? when the router receives an ICMP Time Exceeded message when the host responds with an ICMP Echo Reply message when the value in the TTL field reaches zero when the values of both the Echo Request and Echo Reply messages reach zero when the RTT value reaches zero
when the value in the TTL field reaches zero*
