Exam 200-301 topic 1 question 8 discussion

C is correct! In Spine Leaf architecture... # To increase performance(bandwidth) - Add Spine switch connects to every Leaf Switch # To Increase Access switch ports count - Add leaf switch and connects to every Spine switch

Ref: Cisco Data Center Spine-and-Leaf Architecture: Design Overview White Paper - Cisco “… Spine-and-leaf architecture … If device port capacity becomes a concern, a new leaf switch can be added by connecting it to every spine switch and adding the network configuration to the switch. The ease of expansion optimizes the IT department’s process of scaling the network. …” A. A spine switch and a leaf switch can be added with redundant connections between them. Wrong answer. B. A spine switch can be added with at least 40 GB uplinks. Wrong answer. C. A leaf switch can be added with connections to every spine switch. Correct answer. D. A leaf switch can be added with a single connection to a core spine switch. Wrong answer.

Official Cert Guide: CCNA 200-301 _ Wendell ODOM - Volume 2 - GLOSSARY: page 523 - "spine-leaf network A single-site network topology in which endpoints connect to leaf switches, leaf switches connect to all spine switches (but not to other leaf switches), and spine switches connect to all leaf switches (but not to other spine switches). The resulting topology results in predictable switching paths with three switches between any two endpoints that connect to different leaf switches. " Going by this, "C. A leaf switch can be added with connections to every spine switch" is the correct answer.

CORRECTION: Answer: C. A leaf switch can be added with connections to every spine switch. This allows for scalability in a network when additional access ports are required because each leaf switch can be connected to each spine switch, providing additional capacity and redundancy. This gives the network more flexibility in terms of scalability, making it easier to add more ports and expand the network as needed.

Explanation: A leaf switch can be added with connections to every spine switch. This is a fundamental principle of the spine-and-leaf architecture, which is designed to be a scalable, high-bandwidth, low-latency network topology. By connecting each new leaf switch to every spine switch, the architecture maintains consistent performance and ensures that any device connected to a leaf switch is at most two hops away from any other device in the network.

C is correct

Answer is C

C is correct

answer is c

The correct answer is A. A spine switch and a leaf switch can be added with redundant connections between them. In a spine-and-leaf architecture, the network is organized into two layers: the spine layer and the leaf layer. The spine layer consists of one or more core switches, which are connected to each other and form the backbone of the network. The leaf layer consists of access switches, which are connected to the spine switches and provide connectivity to end devices. When additional access ports are required in a spine-and-leaf architecture, the network can be easily scaled by adding a new spine switch and a new leaf switch. The new spine switch is connected to the existing spine switches with redundant links, and the new leaf switch is connected to the new spine switch. This allows the network to accommodate more devices without disrupting the existing network.

A spine switch and a leaf switch can be added with redundant connections between them

"The leaf layer consists of access switches that connect to devices such as servers." More leaf switches = more access switches = more access ports https://www.cisco.com/c/en/us/products/collateral/switches/nexus-7000-series-switches/white-paper-c11-737022.html

Is correct

When a new leaf switch is added it will have connection to every spine switch So the option (C) is the correct answer

Answer should be option A i think, if i make any mistakes pls correct me i'm a newbie :)
