Network Fundamental Days-4

What is the primary use of NAT?

• To conserve public IPv4 addresses.

• To assign private IPv4 addresses.

• To connect devices within a local network.

What does NAT stand for?

What is the address of the device which is being translated by NAT?

• Inside address

• Outside address

• Local address

• Global address

What is the address of the source as seen from the outside network?

• Inside global address

• Inside local address

• Outside global address

• Outside local address

What is the difference between NAT and PAT?

• NAT modifies only the IPv4 addresses.

• PAT modifies both the IPv4 address and the port number.

• NAT can map multiple private addresses to a single public address.

• PAT does not require a unique Inside Global address for each inside host.

What command is used to verify NAT operation?

• show ip nat translations

• show ip nat statistics

• clear ip nat statistics

What is the first step in configuring static NAT translations?

• Create a mapping between the inside local address and the inside global address.

• Configure the interfaces as inside or outside.

• Verify the NAT operation.

What happens when all addresses in the dynamic NAT pool are in use?

• A device must wait for an available address.

• The device can still access the outside network.

• The NAT process will fail.

What are the five tasks when configuring dynamic NAT translations?

What command is used to define the pool of addresses for dynamic NAT?

• ip nat pool

• ip nat inside source

• access-list

• ip nat inside
