101 Question #46: Real Exam Question with Answer & Explanation
The correct answer is A: The floating self IP address on the VLAN where the packet leaves the system.. SNAT automap translates the client source address to the floating self IP on the egress VLAN, ensuring proper return traffic routing in HA configurations.
Question
Which IP address will the client address be changed to when SNAT automap is specified within a Virtual Server configuration.
Options
- AThe floating self IP address on the VLAN where the packet leaves the system.
- BThe floating self IP address on the VLAN where the packet arrives on the system.
- CIt will alternate between the floating and nonfloating self IP address on the VLAN where the
- DIt will alternate between the floating and nonfloating self IP address on the VLAN where the
Explanation
SNAT automap translates the client source address to the floating self IP on the egress VLAN, ensuring proper return traffic routing in HA configurations.
Common mistakes.
- B. Automap does not use the ingress VLAN's floating self IP - it always uses the floating self IP on the outbound (egress) VLAN where the packet leaves toward the server.
- C. SNAT automap does not alternate between floating and non-floating self IPs; it consistently selects only the floating self IP to maintain HA stability.
- D. SNAT automap does not alternate between addresses, and it uses the egress VLAN, not the ingress VLAN where the client packet arrived.
