Exam 350-401 topic 1 question 28 discussion

A. provide QoS prioritization services such as marking, queueing, and classification for critical network traffic. Distribution layer. B. provide redundant Layer 3 point-to-point links between the core devices for more predictable and faster convergence. Core Layer. C. provide advanced network security features such as 802.1X, DHCP snooping, VACLs, and port security. Access Layer. D. provide redundant aggregation for access layer devices and first-hop redundancy protocols such as VRRP. Distribution layer. https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Campus/HA_campus_DG/hacampusdg.html

remember that teh core layer hates STP, as well as anything that may otherwise hinder convergence. hence, quick convergence is one of its key priorities

B is correct

B is correct

B) - From Cisco: [...] Use redundant point-to-point L3 interconnections in the core (triangles, not squares) wherever possible, because this design yields the fastest and most deterministic convergence results. <<<<< B) IS CORRECT>>>>> DEIGN DOCUMENT - [CORE SECTION] SOURCE: https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Campus/HA_campus_DG/hacampusdg.html

B is the correct answer.

B is correct

Answer B,

Ref: Cisco Three-Tier Architecture Explained - ICTShore.com “… Connecting the Three Tier Architecture … As a best practice, this link must be a Layer 3 point-to-point link. If this is not available due to software limitations, you should avoid a Layer 2 link and have no link at all. This way you will prevent loop and spanning-tree convergence time. Sometimes, even in networking the less is more. …” A. provide QoS prioritization services such as marking, queueing, and classification for critical network traffic Wrong answer. B. provide redundant Layer 3 point-to-point links between the core devices for more predictable and faster convergence Correct answer. C. provide advanced network security features such as 802.1X, DHCP snooping, VACLs, and port security Wrong answer. D. provide redundant aggregation for access layer devices and first-hop redundancy protocols such as VRRP Wrong answer.

All policies are configured an the access and distribution layer, CORE must be use ony to forward packets and be highly redundant an usually be on L3

voting. provided answer is correct.

I agree with all us, the correct answer is B.

QoS can be applied close to a source as possible. Then the best answer is B

B removes the need for spanning tree by using redundant links

Answer B,
