Describe the difference between public and private IPv4 addresses. if a network. If a network is using private IP addresses, how can the computers on that network access the internet?
  • Automatic private IP address (APIPA)
  • Public IP addresses are licensed and authorized to use the internet. Private IP addresses are not authorized or licensed to use the internet. A computer with a private IP address uses a NAT router to access the internet.
  • Private IP addresses.
  • The IP address was automatically assigned by windows when it failed to lease an address from the DHCP server. the computer received an APIPA IP address.
Why is it unlikely that you will find the IP address 192.168.250.10 on the internet?
  • IP addresses that begin with 192.168 are private IP addresses.
  • IP addresses that begins with 2000+ are global addresses used on the internet. Addresses that begin with FE80+ are link local addresses used on a private network.
  • the interface ID which is used uniquely identify the network connection on the local link.
  • HTTPS uses either HTTP together with SSL or TLS encryption protocols
Which TCP/IP protocaol that manages packet delivery guarantees that delivery? which protocol does not guarantee delivery, but is faster?
  • LDAP
  • Port 25
  • TCP, UDP
  • IMAP
How is an IPv6 address used that begins with 2000...? that begins with FE80?
  • IP addresses that begins with 2000+ are global addresses used on the internet. Addresses that begin with FE80+ are link local addresses used on a private network.
  • The subnet ID block contains 16 bits bits. the value of these bits for a link local address are 0000 0000 0000 0000.
  • The IP address was automatically assigned by windows when it failed to lease an address from the DHCP server. the computer received an APIPA IP address.
  • IP addresses that begin with 192.168 are private IP addresses.
How does a client application identify a server application on another computer on the network?

Which protocol(s) does a web server use when transmissions are encrypted for security?
  • IP addresses that begin with 192.168 are private IP addresses.
  • the interface ID which is used uniquely identify the network connection on the local link.
  • HTTPS uses either HTTP together with SSL or TLS encryption protocols
  • LDAP
If no DHCP server is available when a computer configured for dynamic IP addressing connects to the network, what type of IPv4 address is assigned to the computer?
  • The IP address was automatically assigned by windows when it failed to lease an address from the DHCP server. the computer received an APIPA IP address.
  • Remote desktop and Remote Assistance
  • unique local addresses
  • Automatic private IP address (APIPA)
Name two tunneling protocols that are used for IPv6 packets to travel over an IPv4 network.
  • By a port number.
  • ISATAP and TEREDO
  • DHCP server
  • Private IP addresses.
What type of encryption protocol does secure FTP (SFTP) use to secure FTP Transmissions?
  • SSH
  • NAT
  • DHCP server

How many bits are in the subnet ID block? what are the values of these bits for a link-local IP address?
  • There are 48 bits.
  • There are 32 bits in an IPv4 IP address, and 128 bits in an IPv6 IP address.
  • The subnet ID block contains 16 bits bits. the value of these bits for a link local address are 0000 0000 0000 0000.
