CCNA: Cisco Certified Network Associate — Question 768

Which command creates a static NAT binding for a PC address of 10.1.1.1 to the public routable address 209.165.200.225 assigned to the PC?

Answer options

• A. R1(config)#ip nat inside source static 10.1.1.1 209.165.200.225
• B. R1(config)#ip nat outside source static 209.165.200.225 10.1.1.1
• C. R1(config)#ip nat inside source static 209.165.200.225 10.1.1.1
• D. R1(config)#ip nat outside source static 10.1.1.1 209.165.200.225

Correct answer: A

Explanation

The correct command A establishes a static NAT mapping from the internal IP address 10.1.1.1 to the external IP address 209.165.200.225. Option B is incorrect as it tries to configure an external source NAT rather than an internal one. Options C and D also misplace the roles of the internal and external IP addresses in the command syntax.
