Which three statements are true about the Cisco ASA object configuration below? (Choose three.) object network vpnclients range 10.1.100.4 10.1.100.10 object network vpnclients nat (outside,outside) dynamic interface.
The Cisco ASA object configuration creates an object called "vpnclients" which represents a range of IP addresses from 10.1.100.4 to 10.1.100.10. The configuration also specifies NAT translation for this object with the command "nat (outside,outside) dynamic interface". Here are the explanations for the three statements that are true about this configuration:
A. The NAT configuration in the object specifies a PAT rule? Answer: True The "dynamic interface" keyword in the NAT command indicates that the ASA should use Port Address Translation (PAT), also known as NAT overload. This means that multiple internal IP addresses can share a single external IP address. Therefore, statement A is true.
B. This configuration requires the command same-security-traffic inter-interface for traffic that matches this NAT rule to pass through the Cisco ASA appliance. Answer: False The "same-security-traffic" command is used to allow traffic to flow between interfaces with the same security level. However, this configuration specifies the same interface (outside) for both the source and destination of the NAT rule. Therefore, statement B is false.
C. The NAT rule of this object will be placed in Section 1 (Auto-NAT) of the Cisco ASA NAT table? Answer: True The "dynamic" keyword in the NAT command indicates that the ASA should use Auto-NAT, which is Section 1 of the NAT table. Auto-NAT automatically generates NAT rules based on the object configuration. Therefore, statement C is true.
D. This configuration is most likely used to provide Internet access to connected VPN clients. Answer: True This configuration is commonly used to provide Internet access to VPN clients. The NAT rule translates the VPN clients' internal IP addresses to the external IP address of the outside interface, allowing them to access the Internet. Therefore, statement D is true.
E. Addresses in the range will be assigned during config-mode. Answer: False The object configuration only defines a range of IP addresses; it does not assign them to any device or interface. Therefore, statement E is false.
