Which two statements are true about NATs. (Choose two.)
The correct answer is A. NATs support UDP, TCP, and ICMP traffic. C. NATs provide a onetoone mapping between IP addresses. F5 NATs, often referring to static NAT objects, provide a one-to-one mapping between addresses and support various IP protocols including TCP, UDP, and ICMP.
Question
Which two statements are true about NATs. (Choose two.)
Options

- BNATs can be configured with mirroring enabled or disabled.
- CNATs provide a onetoone mapping between IP addresses.
- DNATs provide a manytoone mapping between IP addresses.

Why each option
F5 NATs, often referring to static NAT objects, provide a one-to-one mapping between addresses and support various IP protocols including TCP, UDP, and ICMP.
F5 NATs are capable of translating traffic for various IP protocols, including TCP, UDP, and ICMP, allowing seamless communication while changing source or destination addresses.
While connection mirroring is a feature for high availability on F5 devices, it is primarily configured on virtual servers or globally for connection table synchronization, not as a fundamental characteristic of the NAT object itself.
An F5 NAT configuration creates a static, one-to-one mapping between a specific original IP address and a translated IP address, often used for exposing internal services publicly with a dedicated public IP.
While Source Network Address Translation (SNAT) often provides a many-to-one mapping, a basic F5 NAT object specifically defines a one-to-one static mapping.
