A message is sent to all hosts on a remote network. Which type of message is it? limited broadcast multicast directed broadcast unicast
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 is the binary equivalent of the decimal number 232? 11101000 11000110 10011000 11110010
11101000
What is the decimal equivalent of the binary number 10010101? 149 157 168 192
149
Which three IP addresses are private ? (Choose three.) 10.1.1.1 172.32.5.2 192.167.10.10 172.16.4.4 192.168.5.5 224.6.6.6
172.16.4.4 10.1.1.1 192.168.5.5
What are three characteristics of multicast transmission? (Choose three.) The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255. 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. Computers use multicast transmission to request IPv4 addresses. Multicast messages map lower layer addresses to upper layer addresses.

What field content is used by ICMPv6 to determine that a packet has expired? TTL field CRC field Hop Limit field Time Exceeded field
Hop Limit field
Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host? ARPv6 DHCPv6 ICMPv6 UDP
ICMPv6
What is indicated by a successful ping to the ::1 IPv6 address? The host is cabled properly. The default gateway address is correctly configured. All hosts on the local link are available. The link-local address is correctly configured. IP is properly installed on the host.
IP is properly installed on the host.
192.0.2.123
a TEST-NET address
What are three parts of an IPv6 global unicast address? an interface ID that is used to identify the local network for a particular host 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 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 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
64.102.90.23
a link-local address
127.0.0.1
a loopback address
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? multicast loopback link-local anycast broadcast
loopback, link-local
Which two parts are components of an IPv4 address? subnet portion network portion logical portion host portion physical portion broadcast portion
network portion host portion
172.19.20.5
private 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
Which two things can be determined by using the ping command? the number of routers between the source and destination device the IP address of the router nearest the destination device 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 the average time it takes each router in the path between source and destination to respond
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 uniquely identify a host on a network to identify whether the address is public or private to determine the subnet to which the host belongs to mask the IP address to outsiders
to determine the subnet to which the host belongs
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
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 router receives an ICMP Time Exceeded message when the RTT value reaches zero 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 value in the TTL field reaches zero
