In a collapsed-core architecture, the core and distribution layers are combined and implemented by a single device or a redundant pair. The core layer is responsible for forwarding large amounts of packets both reliably and quickly. The distribution layer, on the other hand, manages connectivity between the core and access layers, based on policies and boundaries worked into the network. Therefore, the correct answer is **C. The router operates on a single device or a redundant pair**.
Option 'c' is correct.
What "interesting" answers to choose from!
Option 'a' is incorrect - HSRP and IPv6 is irrelevant.
Option 'b' is incorrect - To deploy on different devices tends to suggest that the core and distribution layers are not collapsed.
Option 'c' is correct - by joining the core and distribution layers, a single device can be used to provide this functionality.
Option 'd' is incorrect. Dual-stacked devices are irrelevant.
Takeaway learnings: asinine answers.
C is correct, the CORE and Distribution layer are collapsed (unified) into one and using only one device (router, SW...). However, it usually uses two collapsed layer devices (pair) for redundancy or load distribution.
That's wrong. A collapsed core architecture takes the normal three-tier hierarchical network and collapses it into a two-tier network. In a two-tier network, the function of the switches in the core layer and distribution layer are “collapsed” into a combined core and distribution layer on a single switch.
How can B be better? are you studying or just guess? unbelivable
