Palo Alto Networks Certified Network Security Administrator (PCNSA) — Question 212

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?

Answer options

• A. Dynamic IP
• B. Static IP
• C. Dynamic IP and Port
• D. Destination NAT

Correct answer: A

Explanation

The correct answer is Dynamic IP NAT because it allows a pool of public IP addresses to be shared among multiple private IP addresses, and in this case, the pool is insufficient for the number of addresses needing translation. Static IP NAT would not apply here as it maps a single private IP address to a single public IP address, which does not address the issue of dropped connections due to insufficient addresses.
