An administrator manages a network with 300 addresses that require translation. The administrator configured NAT with an address pool of 240 addresses and found that connections from addresses that needed new translations were being dropped.
Which type of NAT was configured?
In a Dynamic IP NAT configuration, a pool of public IP addresses is assigned to incoming connections from a range of internal IP addresses. If the number of internal addresses exceeds the number of addresses in the pool (as in this case, where there are 300 internal addresses but only 240 in the pool), new connections that require translation will be dropped.
The size of the NAT pool should be equal to the number of internal hosts that require address translations. By default, if the source address pool is larger than the NAT address pool and eventually all of the NAT addresses are allocated, new connections that need address translation are dropped. To override this default behavior, use Advanced (Dynamic IP/Port Fallback) to enable the use of DIPP addresses when necessary
A is correct, Question is 'Which type of NAT WAS configured?', not 'Which type of NAT SHOULD BE configured?'
Asking about the NAT type used and not what should be used. Answer is A Dynamic IP
Correct
A. Dynamic IP
A. Dynamic IP In a Dynamic IP NAT configuration, a pool of public IP addresses is assigned to incoming connections from a range of internal IP addresses1. If the number of internal addresses exceeds the number of addresses in the pool (as in this case, where there are 300 internal addresses but only 240 in the pool), new connections that require translation will be dropped
DIPP is used for what is called "PAT"
Dynamic IP—Translates to the next available address in the specified range but the port number remains unchanged.
The answer should be A.
