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 mask the IP address to outsiders
-

A message is sent to all hosts on a remote network. Which type of message is it?
- limited broadcast
- multicast
- directed broadcast*
- unicast
-
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 type of address is automatically assigned to an interface when IPv6 is enabled on that interface?
- global unicast
- link-local*
- loopback
- unique local
-
What are three parts of an IPv6 global unicast address? (Choose three.)
- 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*
-
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
-
Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?
- ARPv6
- DHCPv6
- ICMPv6*
- UDP
-
Which two things can be determined by using the ping command? (Choose two.)
- 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
-
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
-
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.*
-
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*
