Exam 200-301 topic 1 question 751 discussion

A if we are being asked about benefits of deployment D if we are being asked about device management

D is correct. Automation: Using controllers and open APIs, Cisco DNA simplifies network management through abstraction and centralized policy enforcement that allows IT to focus on business intent and consistently apply configurations to improve service and keep operations consistently secure from the core to the edge. https://www.cisco.com/c/en/us/solutions/collateral/enterprise-networks/digital-network-architecture/nb-06-digital-nw-architect-faq-cte-en.html

D is correct

Option A states, “Its modular design allows the implementation of different versions to meet the specific needs of an organization.” While it’s true that Cisco DNA Center has a modular design, this doesn’t necessarily mean it allows for the implementation of different versions to meet specific organizational needs. The modular design of Cisco DNA Center refers to its ability to manage different aspects of the network (like design, policy, provision, and assurance) in a structured and organized manner. However, this doesn’t imply that different versions of Cisco DNA Center can be implemented. Instead, it’s about how the single version of Cisco DNA Center that an organization has can be used in a flexible and scalable way. Therefore, while option A contains some elements of truth, it’s not the best answer to the question about what makes Cisco DNA Center different from traditional network management applications.

I guess A is not wrong but a fact that is possible in both management types, however, D is the real difference between these two designs.

The primary characteristic and difference is still the separation of control and data plane: How is the policy abstract or abstracted from the device configuration? -It is separated from the device configuration. It is implemented on a higher, centralized level. -It is configured (mostly) in a GUI, which is a different way of interfacing than on the devices themselves. A is aiming more for qualities like for example scalability. And the way the sentence is worded would imply that traditional networking is not scalable (or very limited) to the needs of an organization.

CISCO DNA Center abstracts policy, correct. However, it does abstract (summarise) policy from the intent (from top) and not from the actual devices configuration. The abstracted policy is down enforced to actual devices (not vice versa). Hence D violates actual intention of DNA/SDN networks. A is correct. It is one goal of SDNs and Centralized controllers.

Correct Answer: B A. DNA is single pane of glass. The answer says modular but after that the answer is too vague. ​ B. Auto-discovery only in greenfield, brownfield you have to manually add the device. Traditional Management requires manual adding too (this is the difference) ​ C. Cluster is for HA​ D. The Cisco DNA controller translates abstract expression of policy into actual device configuration. Not the other way around, as D suggests. ​ Reference Link: https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/1-2/iwan/quick-start/iwan-app-quick-start-2-2/workflows.pdf

WHAT IS DIFFERENT - between old & new is being asked... Not Benefits - Not Device Management

Automation is STEP 4 in a GREENFIELD deployment See: ===> Cisco DNA Center SD-Access LAN Automation Deployment Guide <===

Greenfield deployment refers to the installation of an IT system where previously there was none. ===> Cisco DNA Center SD-Access LAN Automation Deployment Guide <=== In four main steps, the Cisco LAN automation workflow helps enterprise IT administrators prepare, plan, and automate greenfield networks: Step 1 Plan: Understand the different roles in the LAN automation domain. Plan the site and IP pool and understand the prerequisites for seed devices. Step 2 Design: Design and build global sites. Configure global network services and site-level network services. Configure global device credentials. Design the global IP address pool and assign the LAN automation pool. Step 3 Discover: Discover seed devices. Step 4 Provision: Start and stop LAN automation: A: Start LAN automation: Push the temporary configuration to seed devices, discover devices, upgrade the image, and push the initial configuration to discovered devices. B: Stop LAN automation: Convert all point-to-point links to Layer 3.

D is correct. Explanation: AI endpoint analytics Implementation of DPI and other methods to identify endpoint clients upon accessing the network. Then uses AI/ML to place them into logical groups so that policies can be assigned based on the endpoint requirements.

Because Cisco DNA center is using intent-based Network, so I believe option D "It abstracts policy from the actual device configuration." is incorrect it should be it abstracts policy from intents...

The question asks basically to compare DNA with PI and the answer is de SDA capability. So, I agree with "D"

Provision: Once you have created policies in Cisco DNA Center, provisioning is a simple drag-and-drop task. The profiles (called scalable group tags or “SGTs”) in the Cisco DNA Center inventory list are assigned a policy, and this policy will always follow the identity. The process is completely automated and zero-touch. New devices added to the network are assigned to an SGT based on identity—greatly facilitating remote office setups.

You don't have to fret. D is the correct answer.

I am confuse about A and D but I think A is correct.from my research.
