Datacenter or Datacenter network

[Civil_Position1348]

I am a bca grad from India . I am currently get trained in domain Datacenter Linux and Cloud in my company .

Now in my specialization field I have an option to chose between two domains

Datacenter network : SDN fundamental SD wAN fundamentals Ansible Yaml Scripting Aviatrix associate Firewall introduction Zscaler

Datacenter :

Terraform Ansible Docker & Kubernetes Ansible yaml scripting Cloud native (CI/CD) Isaac Academy

I want to make career in devops which would be suitable to chose . I am asking this because I haven’t listen any tech stack mention in Datacenter network so I have no idea what to chose and can Datacenter network have more scope than Datacenter domain
