Question 13
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?
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

Question 15
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 the origin server were to initiate traffic via the BIG-IP, What changes, if any, would take place when the BIG-IP processes such packets?
A. The BIG-IP would drop the request since the traffic didn’t arrive destined to the NAT address.
B. The source address would not change, but the destination address would be changed to the NAT address.
C. The source address would be changed to the NAT address and destination address would be left unchanged.
D. The source address would not change, but the destination address would be changed to a self-IP of the BIG-IP.
