True or False? A side effect of NAT is that it hides the inside local IP address of a host from the outside network.

• True
• False

True or False? The use of NAT makes end-to-end traceability between source and destination easier.

• True
• False

True or False? Tunneling protocols such as IPsec do not work well through NAT.

• True
• False

True or False? With NAT overload, each inside local IP address is translated to a unique inside global IP address on a one-for-one basis.

• True
• False

A company designs its network so that the PCs in the internal network are assigned IP addresses from DHCP servers, and the packets that are sent to the Internet are translated through a NAT-enabled router. What type of NAT enables the router to populate the translation table from a pool of unique public addresses, as the PCs send packets through the router to the Internet?

• ARP
• dynamic NAT
• PAT
• static NAT

A company has been assigned the 203.0.113.0/27 block of IP addresses by the ISP. The company has over 6000 internal devices. What type of NAT would be most appropriate for the employee workstations of the company?

• dynamic NAT
• dynamic NAT overload using the pool of addresses
• PAT off the external router interface
• port forwarding
• static NAT

A network administrator configures the border router with the ip nat inside source list 4 pool NAT-POOL global configuration command. What is required to be configured in order for this particular command to be functional?

• A NAT pool named NAT-POOL that defines the starting and ending public IPv4 addresses
• A VLAN named NAT-POOL that is enabled and active and routed by R1
• An access list named NAT-POOL that defines the private addresses that are affected by NAT
• An access list numbered 4 that defines the starting and ending public IPv4 addresses
• ip nat outside enabled on the interface that connects to the LAN affected by NAT
