DWS Preparation — Wipro Prep Portal

Key Concepts

Docker — Images, Containers, Volumes
Dockerfile + Multi-stage builds
Kubernetes Pods, Services, Deployments
Helm Charts — Package management
Ingress Controllers + Load Balancing

Sample Docker Commands

# Build and run a container
docker build -t myapp:latest .
docker run -d -p 80:80 myapp:latest

# Push to Azure Container Registry
az acr login --name myRegistry
docker tag myapp myRegistry.azurecr.io/myapp
docker push myRegistry.azurecr.io/myapp

# AKS deploy
kubectl apply -f deployment.yaml
kubectl get pods -n default
      

What is the difference between Azure AD and on-premises Active Directory? ▼

Azure AD is a cloud-based identity service that supports modern protocols like OAuth2, SAML, and OpenID Connect. On-prem AD uses Kerberos/LDAP for traditional domain environments. Azure AD Connect can sync both. In DWS context, hybrid identity using Azure AD + Intune is the standard for managing both cloud and physical devices.

How does Intune enforce device compliance? ▼

Intune uses Compliance Policies to define minimum requirements (e.g., OS version, encryption, PIN). These work with Azure AD Conditional Access — if a device is non-compliant, access to apps like Outlook or Teams is blocked until the user remediates the issue. This is the heart of zero-trust in DWS environments.

Explain AKS vs standalone Kubernetes. ▼

AKS is Azure's managed Kubernetes service — Azure handles the control plane, OS patching, upgrades, and scaling. With standalone K8s, you manage everything. AKS integrates natively with Azure Monitor, Azure AD, ACR, and Azure Load Balancer, making it the preferred choice for enterprise DWS workloads.

What is RBAC and how do you implement least privilege? ▼

RBAC (Role-Based Access Control) in Azure assigns roles like Owner, Contributor, Reader to users/groups at scope levels: Management Group → Subscription → Resource Group → Resource. Least privilege means granting only the minimum permissions required — e.g., a developer gets Contributor on their resource group only, not the entire subscription.

What is Nexthink DEX Score and why does it matter? ▼

DEX (Digital Employee Experience) Score is Nexthink's composite metric measuring the health of an employee's digital environment — covering device performance, application crashes, network quality, and sentiment. A low DEX score triggers automated remediation via Remote Actions. In DWS, it's used to proactively fix issues before users raise tickets, improving SLAs.
