Exam 350-401 topic 1 question 499 discussion

Answer should be: Process switching uses the general CPU and is referred to as software switching CEF Can handle larger amounts of traffic

PROCESS SWITCHING - It is referred to as "Software Switching" - The general purpose CPU is in charge of packet switching CEF - It optimizes the switching process to handle larger packet volumes

CEF has dedicated hardware components to handle packet forwarding, while process switching utilizes the CPU for every packet forward. CEF can handle more traffic than traditional process switching. CEF: Hardware-based, can handle more traffic (used in high-performance environments). PS: Software-based, slow, and handles less traffic (used for lower-end devices).

given answer is incorrect Process Switching: - It is referred to as "software switching" - The general-purpose CPU is in charge of packet switching Cisco Express Forwarding : - It optimizes the switching process to handle larger packet volums

How could admin get this wrong... CEF has been explained as hardware switching in numerous docs. the only answer that really compliments CEF is optimizes blah blah... you know Cisco always boosts its own tech. Easy gimme question!

How could you get this wrong? Process Switching Process switching, also referred to as software switching or slow path, is a switching mechanism in which the general-purpose CPU on a router is in charge of packet switching. In IOS, the ip_input process runs on the general-purpose CPU for processing incoming IP packets. Process switching is the fallback for CEF because it is dedicated to processing punted IP packets when they cannot be switched by CEF. Cisco Express Forwarding (CEF) is a Cisco proprietary switching mechanism developed to keep up with the demands of evolving network infrastructures. It has been the default switching mechanism on most Cisco platforms that do all their packet switching using the general-purpose CPU (software-based routers) since the 1990s, and it is the default switching mechanism used by all Cisco platforms that use specialized application-specific integrated circuits (ASICs) and network processing units (NPUs) for high packet throughput (hardware-based routers).

What is wrong with these people publishing the answers? Since when is CEF related to software and CPU?

Given answer is incorrect. From the ENCOR book: Process switching: Every packet\frame examined by CPU All forwarding decisions made in software

PROCESS SWITCHING o it is referred as software sw the general purpose CPU is in charge of packet sw CEF it optimizes the switching process to handle larger packet volumes

The answer is wrong according by https://study-ccnp.com/process-switching-mechanism-explained/

Given answer is bs. Siteoforigin is correct.

agree with "siteoforigin ",
