Exam MTCNA Topic 2 Question 108 Discussion

The redirect action is a specialized type of destination NAT (dst-nat) used to force traffic to a local port on the router (typically for transparent proxies or redirection to hotspot portals). This action is only valid in DST- NAT rules and does not apply to firewall filters, routing rules, or source NAT.
Option breakdown:
* A.#Firewall Filter - These rules allow, drop, or reject traffic, not perform redirection.
* B.#DST-NAT - Redirect is a valid dst-nat action and is processed in the prerouting chain.
* C.#Route - Routing rules do not include NAT actions.
* D.#SRC-NAT - Used for source address translation, not redirection.
