F5 TMOS Administration — Question 3

Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If a client were to initiate traffic to the NAT address, what changes, if any, would take place when the BIG-IP processes such packets?

Answer options

• A. The source address would not change, but the destination address would be translated to the origin address.
• B. The destination address would not change, but the source address would be translated to the origin address.
• C. The source address would not change, but the destination address would be translated to the NAT's address.
• D. The destination address would not change, but the source address would be translated to the NAT's address.

Correct answer: A

Explanation

The correct answer is A because when a client sends traffic to the NAT address, the NAT translates the destination address to the origin address while keeping the source address intact. The other options are incorrect as they either misrepresent the roles of source and destination addresses or suggest changes that do not occur under the specified conditions.
