Which of the following statements are TRUE about iStack and CSS?

Correct Answer:ABC
iStack (Intelligent Stacking)andCSS (Cluster Switching System)are twohigh- availability networking technologiesused to logically combine multiple switches for better redundancy and scalability.
(A) True – CSS (Cluster Switching System)allowstwo or more modular switchesto function
as one logical switch. CSS-capable switches connect usingCSS cables.
(B) True – iStackallows multiplefixed switchesto be stacked together into a single logical unit usingiStack cables.
(C) True – CSS is supported by modular switches, whileiStack is supported by fixed switches. Onlytwoswitches can form a CSS cluster.
(D) False – iStack supports more than two switches, making this statement incorrect. Reference:HCSA-Presales-IP Network Official Study Guide, iStack & CSS Section
