F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 79

Given a tcpdump on an LTM device from both sides of a connection on the External and Internal VLANs, how should an LTM Specialist determine if SNAT is enabled for a particular pool?

Answer options

• A. by checking to see if the Source IP is carried through from the External Vlan to the Internal Vlan
• B. by checking to see if the Destination port is carried through from the External Vlan to the Internal Vlan
• C. by checking to see if the Source port is carried through from the External Vlan to the Internal Vlan
• D. by checking to see if the Destination IP is carried through from the External Vlan to the Internal Vlan

Correct answer: A

Explanation

The correct answer is A because if SNAT is enabled, the original Source IP is replaced with the SNAT IP when traffic passes from the External VLAN to the Internal VLAN. Options B, C, and D are incorrect because they relate to ports and Destination IP, which do not indicate whether SNAT is being applied.
