What is indicated by a successful ping to the ::1 IPv6 address?
  • IP is properly installed on the host

Which two ICMP messages are used by both IPv4 and IPv6 protocols? (Choose two.)​
  • route redirection
  • protocol unreachable

What are three parts of an IPv6 global unicast address? (Choose three.)
  • 1. a subnet ID that is used to identify networks inside of the local enterprise site
  • 2. an interface ID that is used to identify the local host on the network
  • 3. a global routing prefix that is used to identify the network portion of the address that has been provided by an ISP

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?
  • solicited-node multicast address

Which two statements are correct about IPv4 and IPv6 addresses? (Choose two.)
  • IPv4 addresses are 32 bits in length.
  • IPv6 addresses are represented by hexadecimal numbers.

A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 192.168.10.0/24. There are 3 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts?
  • 251

Which two things can be determined by using the ping command? (Choose two.)
  • whether or not the destination device is reachable through the network

Fill in the blank.
What is the decimal equivalent of the hex number 0x3F?
  • 63

Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?
  • tunneling

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