The correct answer is D. overload.
Port Address Translation (PAT), also known as NAT overload, is a type of Network Address Translation (NAT) that allows multiple hosts on a private network to share a single public IP address. It works by assigning unique source port numbers to each session, which allows the router to distinguish between different connections originating from the same internal network.
In order to configure PAT, you must specify the inside and outside interfaces of the router, as well as the IP address of the outside interface. You must also specify the pool of IP addresses that will be used for translation, as well as the number of ports that will be used for each translation.
The "overload" keyword is used to enable PAT on the router. It tells the router to use the available ports as efficiently as possible, which allows multiple internal hosts to share a single public IP address.
Option A, Dynamic Routing, is not related to PAT. It is a method of automatically determining the best path for data to travel through a network.
Option B, DNS, is also not related to PAT. DNS is a protocol used to translate domain names into IP addresses.
Option C, Preempt, is a feature used in redundancy protocols such as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP). It allows a backup router to take over as the active router in the event of a failure. It is not related to PAT.
