Practice - 5 Tasks

1fill in blank

easy

Complete the code to deploy the SCADA data collector service on the cloud.

SCADA systems

kubectl apply -f [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using a JSON or script file instead of YAML for kubectl apply.

The kubectl apply -f command requires a YAML file describing the deployment. Here, scada-collector.yaml is the correct file.

2fill in blank

medium

Complete the command to check the status of the SCADA collector pods.

SCADA systems

kubectl get pods -l app=[1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using unrelated labels like 'database' or 'sensor'.

The label app=collector selects pods related to the SCADA data collector service.

3fill in blank

Fix the error in the command to expose the SCADA collector service on port 8080.

SCADA systems

kubectl expose deployment scada-collector --type=[1] --port=8080

Drag options to blanks, or click blank then click option'

CNodePort

DClusterIP

💡 Hint

Common Mistakes

Using ClusterIP which is internal only.

To expose the service externally on port 8080, LoadBalancer type is used in cloud environments.

4fill in blank

hard

Fill both blanks to create a ConfigMap for SCADA collector settings.

SCADA systems

kubectl create configmap [1] --from-file=[2]

Drag options to blanks, or click blank then click option'

Ascada-config

Bcollector-settings.yaml

Cscada-collector

Dconfig.yaml

Attempts:

💡 Hint

Common Mistakes

Using deployment names instead of config names.

The ConfigMap is named scada-config and created from the file collector-settings.yaml.

5fill in blank

hard

Fill all three blanks to define a Kubernetes secret for SCADA credentials.

SCADA systems

kubectl create secret generic [1] --from-literal=[2]=[3]

Drag options to blanks, or click blank then click option'

Ascada-credentials

Busername

Cscada_user

Dpassword

Attempts:

💡 Hint

Common Mistakes

Confusing secret name with key or value.

The secret is named scada-credentials and stores the literal username=scada_user.
