F5 Application Delivery Fundamentals — Question 15

A BIG-IP has two load balancing virtual servers at 150.150.10.10:80 and 150.150.10.10:443. The port 80 virtual server has SNAT automap configured. There is also a SNAT configured 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 https://150.150.10.10, 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: B

Explanation

The source IP address will be changed to the configured SNAT at 150.150.10.11, which matches the source address range of the client. Option A is incorrect as it represents the original client IP, which will be altered by the SNAT. Options C and D do not apply because they refer to self IP addresses on VLANs, which are not relevant in this scenario.
