Check Point Certified Security Expert (CCSE) R81 — Question 41

In which scenario will an administrator need to manually define Proxy ARP?

Answer options

• A. When they configure an "Automatic Static NAT" which translates to an IP address that does not belong to one of the firewall’s interfaces.
• B. When they configure an "Automatic Hide NAT" which translates to an IP address that does not belong to one of the firewall’s interfaces.
• C. When they configure a "Manual Static NAT" which translates to an IP address that does not belong to one of the firewall’s interfaces.
• D. When they configure a "Manual Hide NAT" which translates to an IP address that belongs to one of the firewall’s interfaces.

Correct answer: C

Explanation

The correct answer is C because manual Proxy ARP is necessary when configuring a 'Manual Static NAT' that translates to an address not associated with the firewall's interfaces. Options A and B refer to automatic NAT configurations, which do not typically require manual Proxy ARP. Option D relates to a configuration that doesn't necessitate Proxy ARP since it involves an address within the firewall's interfaces.
