In which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?
A spine-and-leaf architecture is designed to provide high scalability, optimized bandwidth, and low latency. In this architecture, leaf switches serve as the access layer and connect to every spine switch in a full-mesh topology. By adding a new leaf switch and connecting it to all existing spine switches, the network can easily expand its access port capacity without causing bottlenecks or disrupting existing connections. This ensures that the network remains scalable and maintains high performance as more devices are connected.
The correct answer is: C. A leaf switch can be added with connections to every spine switch.
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 Support: https://www.cisco.com/c/en/us/products/collateral/switches/nexus-7000-series-switches/white-paper-c11-737022.html
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.
Answer should be option A i think, if i make any mistakes pls correct me i'm a newbie :)
I think you dont use lacp between spine and leaf but Im a newbie myself
OCG doesnt say anything about it
If I remember correctly, you can add redundant links in a spine-leaf topology. However, C is the correct answer because it meets the necessary conditions for creating this type of topology, that is, one link between every spine and every leaf switches.
The answer is C because you can only connect leaf switches to more spine switches. Spine switches does the same but completely opposite
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.
When a new leaf switch is added it will have connection to every spine switch So the option (C) is the correct answer
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.
Your answer is incorrect because it is not necessary to add a spine every time you add a leaf or vice versa. Leaf switches expand port capacity but a spine switch is necessary when its plane becomes oversubscribed.

Is correct
"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
A spine switch and a leaf switch can be added with redundant connections between them
C is correct
Answer is C
C is correct
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.
