Question
What two parts are components of an IPv4 address? (Choose two.)
Answer
  • subnet portion
  • network portion
  • logical portion
  • host portion
  • physical portion
  • broadcast portion

Question 3

Question
What does the IP address 172.17.4.250/24 represent?
Answer
  • network address
  • multicast address
  • host address
  • broadcast address

Question 4

Question
What is the purpose of the subnet mask in conjunction with an IP address?
Answer
  • 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

Answer
  • 255.255.255.248
  • 255.255.224.0
  • 255.255.240.0

  • 255.255.255.192

Question 6

Question
A message is sent to all hosts on a remote network. Which type of message is it?
Answer
  • limited broadcast
  • multicast
  • directed broadcast
  • unicast

Question 7

Question
What are three characteristics of multicast transmission? (Choose three.)
Answer
  • 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.

Question 8

Question
Which three IP addresses are private ? (Choose three.)
Answer
  • 10.1.1.1
  • 172.32.5.2
  • 192.167.10.10
  • 172.16.4.4
  • 192.168.5.5
  • 224.6.6.6

Question
Which two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains? (Choose two.)
Answer
  • trunking
  • dual stack
  • encapsulation
  • tunneling
  • multiplexing

Question 10

Question
Which of these addresses is the shortest abbreviation for the IP address: 3FFE : 1044 : 0000 : 0000 : 00AB : 0000 : 0000 : 0057?
Answer
  • 3FFE : 1044 :: AB :: 57
  • 3FFE : 1044 :: 00AB :: 0057
  • 3FFE : 1044 : 0 : 0 : AB :: 57
  • 3FFE : 1044 : 0 : 0 : 00AB :: 0057
  • 3FFE : 1044 : 0000 : 0000 : 00AB :: 57
  • 3FFE : 1044 : 0000 : 0000 : 00AB :: 0057

Answer
  • global unicast
  • link-local
  • loopback
  • unique local

Question 12

Question
What are two types of IPv6 unicast addresses? (Choose two.)
Answer
  • multicast
  • loopback
  • link-local
  • anycast
  • broadcast

Question 13

Question
What are three parts of an IPv6 global unicast address? (Choose three.)
Answer
  • 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

Question 14

Question
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?
Answer
  • SLAAC
  • stateless DHCPv6
  • stateful DHCPv6
  • RA and EUI-64

Question 15

Question
Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?
Answer
  • ARPv6
  • DHCPv6
  • ICMPv6
  • UDP

Question 16

Question
Which two things can be determined by using the ping command? (Choose two.)
Answer
  • 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

Question 17

Question
What is the purpose of ICMP messages?
Answer
  • 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

Question 18

Question
What is indicated by a successful ping to the ::1 IPv6 address?
Answer
  • 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.

Answer
  • 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
