F5 TMOS Administration — Question 22

A BIG-IP has a virtual server at 150.150.10.10:80 with SNAT automap configured. This BIG-IP also has a SNAT at 150.150.10.11 set for a source address range of 200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to the virtual server, what is the source IP address when the associated packet is sent to the pool member?

Answer options

• A. 200.200.1.1
• B. 150.150.10.11
• C. Floating self IP address on VLAN where the packet leaves the system
• D. Floating self IP address on VLAN where the packet arrives on the system

Correct answer: C

Explanation

The correct answer is C because when SNAT automap is used, the source IP address of the outgoing packet is replaced with the self IP address of the BIG-IP on the VLAN where the packet exits. Options A and B are incorrect because they do not represent the IP address used when the packet leaves the system, while option D refers to the IP address relevant to incoming packets, not outgoing ones.
