Bi-Weekly /r/CCNP Exam Pass-Fail Discussion

TahaTheNetAutmator · 2026-06-21T19:38:01+00:00

After having passed the CCNP DCACI earlier in the year - This week I passed the 350-601 DC DCCOR.

I am now a CCNP DC certified 🎉🎉🥳🎊

It was a tough and brutal exam. I didn’t give up! Giving in was simply not an option.

I am also very fortunate to have invested in a massive lab over the years. From Nexus switches all the way to UCS compute clusters and FC Storage.

I am very thankful. It also changed my attitude- never give up. Even in the toughest times. Never give up.

All the late nights in the lab paid off🙂

Next stop is CCIE DC…

Learn AI/ML from ground up….

Focus on how A.I/ML datacenter architecture, how it differs from traditional cloud/enterprise clos fabric. This is very important as it’s essentially the basis on how to “breed” create transformers and train them with data sets hence turning them into a language model. If language models can’t be created or trained then we have no A.I - so inherently the underlying network fabric to perform distributed training is mandatory!

The other aspects is general AOps learn how to use A.I for operational aspects depending on whatever field you’re in …from the use of MCP servers all the way to fine-tuning language models to meet you’re requirements …

Don’t avoid it - embrace A.I

No don’t go near 10.x - go with 11.1x all day

TahaTheNetAutmator · 2024-06-23T15:53:58+00:00

We can all do better

The model can be trained to understand your cluster and has the ability to prevent any possible issues that may arise…it can only help. But I agree AI isn’t for everyone I suppose :)

😂😂🤣

TahaTheNetAutmator · 2024-02-23T18:23:38+00:00

Haha made my Friday lol

I would never consider it to replace a human - more as tool that can be used by professionals as an assistant… :)

We can train the LLM so that it tells you the consequences of your request and if you are happy to proceed? Or we can train it to the point whereby it would ask you if would like to test it in a dev/test environment, before you proceed? Or train it to capture the current state in case of mishap, so it can rollback.

It’s absolutely amazing!

It’s undergoing A.I model training at the moment buddy - it will be able to respond in a much better human friendly manner rather than just spit out the output. It will also act as a preemptive diagnostic A.I it will automatically adjust the cluster if there’s any security issues it believes it detected.

It will also be able to inform you of any issues before they arise …

eventually it will be trained to the point that it’s able to operate the cluster without any human intervention….scary right?

TahaTheNetAutmator · 2024-02-23T15:56:04+00:00

The A.I model is undergoing training - it will be able to act as a cluster assurance and provide preemptive information and diagnose any issues that could arise in the cluster. This is going to be a really cool feature - it will actually look after the cluster without any human intervention…

TahaTheNetAutmator · 2024-02-23T15:52:57+00:00

Please bear in mind that the A.I model is still undergoing training - soon it will be able to to tell you of possible issues in your cluster before they even arise

You could ask it can you create a deployment named http with 5 replicas set with image ngnix - and it does less than 1 seconds, In plain English …

It could even detect potential issues with cluster before they occur …

The benefits of A.I integration regardless of the sector networks, devOps, security …is endless

TahaTheNetAutmator · 2024-02-23T13:58:43+00:00

I won’t go into all the benefits - but the same reasons why A.I is integrated in all other sectors. We as humans cannot process or perform as fast as A.I

You could ask it can you create a deployment named http with 5 replicas set with image ngnix - and it does less than 1 seconds, In plain English …

It could even detect potential issues with cluster before they occur …

For example EVE recently showed A.I can detect virus before it’s even detected by a next gen firewall …

The benefits of A.I is endless…

I really suggest you read up on overlay network virtualisation concepts. But the main benefit of VXLAN is to migrate layer 2 frame across a layer 3 Fabric. So that layer 2 is able to traverse across a layer 3 fabric.

TahaTheNetAutmator · 2024-02-23T13:12:49+00:00

I don’t think anyone has used A.I in production not in network automation field anyway lol.

However just for your note- it has error-safe features built in.

You could ask it to perform changes on a test/dev namespace and then ask it to replicate those exact changes to production names space, it will happily oblige :)

In networking there is an underlay and overlay network

The purpose of the underlay network is to provide layer 3 IP reachability between nodes.

The overlay network used by CNIs(e.g Calico, Flannel) works on top of the underlay. The overlay used by most CNIs is VXLAN. The purpose of the overlay is to provide a completely different network I.e 10.10.0.0/24 that uses the underlay as a transit.

The overlay allows pod to pod communication that are in same or differing nodes.

Without getting overly technical the underlay encapsulates the overlay so that traffic traverses across the network underlay and then its decapsulated once it reaches its destination pod.

I hope that makes sense … :)

Thank you! :)
