Question 17

Network address translation (NAT) -

Answer 17

The changing of an IP address as it progresses through a network, usually from private to public or vice versa.

Question 18

Port address translation (PAT) -

Answer 18

Translation of port numbers from source to destination and vice versa.

Question 19

Automatic Private IP Addressing (APIPA) -

Answer 19

Link local address. Automatically assigned. Unable to communicate with the router

Question 20

Extended unique identifier (EUI-64) - .

Answer 20

Extends the MAC address into a 64 bit value to Form half of an IPv6 address.

Question 21

Multicast

Answer 21

One to many of many communication (only those who want it).

Question 22

Unicast –

Answer 22

One to one communication

Question 23

Anycast -

Answer 23

One to one of many communication (data is delivered only to the closest device with the correct anycast address).

Question 24

Broadcast -

Answer 24

One to all communication

Question 25

Link local -

Answer 25

Same as APIPA.

Question 26

Default gateway -

Answer 26

The IP address of the device which provides a gateway out of the network. The router.

Question 27

Classless (variable-length subnet mask(VLSM)-

Answer 27

Allow network administrators to define their own masks

Question 28

Classless Inter-Domain Routing (CIDR) notation

Answer 28

efficient method of assigning IP addresses that improves address distribution and replaces the previous Class A, Class B and Class C networks system

Question 29

Tunneling

Answer 29

6to4 addressing allows sending of IPv6 traffic over an IPv4 network. 4in6 does the opposite

Question 30

Teredo tunneling

Answer 30

Windows. allow tunnelling of IPv6 through NATed IPv4 networks with no special routers needed.

Question 31

Miredo tunneling

Answer 31

Linux/BSD/macOS. allow tunnelling of IPv6 through NATed IPv4 networks with no special routers needed.

Question 32

Dual stack

Answer 32

Running both IPv4 and IPv6 simultaneously.

Question 33

Router advertisement -

Answer 33

IPv6 has no broadcast. this is managed by Neighbor Discovery Protocol (NDP) using multicast.

Question 34

Stateless address autoconfiguration (SLAAC) -

Answer 34

The automatic configuration of IP addresses in IPv6 (without a DHCP server).

Question 35

Virtual IP (VIP) -

Answer 35

An IP address not associated with a physical network adapter.

Question 36

Subinterfaces -

Answer 36

One physical network interface handling multiple VLANs.

Question 37

RFC1918 -

Answer 37

Defines private IP address ranges.
