Technical Service Specialist Interview Questions and Answers

Docker is a containerization platform that allows developers to package and deploy applications in a portable manner.

• Dockerfile is a script that contains instructions to build a Docker image

• Best practices include keeping the image size small, using a single process per container, and using environment variables for configuration

• Use multi-stage builds to reduce image size and improve security

• Avoid running containers as root to minimize security risks

• Regularly update base image...read more

The DevOps project involves continuous integration, delivery, and deployment of software. Kubernetes components include pods, services, deployments, and namespaces.

• The DevOps process starts with developers committing code to a version control system like Git.

• The code is then built and tested using continuous integration tools like Jenkins.

• The built code is packaged into containers using tools like Docker.

• The containers are deployed to a Kubernetes cluster using tools like kub...read more

Restarting pods in clusters involves identifying the affected pod, deleting it, and allowing the cluster to create a new one.

• Identify the affected pod using kubectl get pods command

• Delete the pod using kubectl delete pod command

• Allow the cluster to create a new pod automatically

• Use kubectl rollout restart command to restart all pods in a deployment

• Use kubectl scale command to increase or decrease the number of replicas in a deployment

To control sag and run down during application, proper viscosity, temperature control, and application techniques are key.

• Use the correct viscosity of the material for the application

• Maintain proper temperature control to prevent sagging or running down

• Apply the material in thin layers or use techniques like brushing or rolling instead of pouring

• Consider using additives or thickeners to adjust the viscosity as needed

To hide roles in SAP GRC, we can use the 'hidden' attribute in the role definition.

Various tests are conducted on dry coatings to ensure quality and performance.

• Adhesion test to check how well the coating sticks to the substrate

• Hardness test to measure the resistance of the coating to indentation or scratching

• Abrasion test to evaluate the coating's resistance to wear and tear

• Impact test to assess the coating's ability to withstand sudden force or shock

• Flexibility test to determine the coating's ability to bend without cracking

• Chemical resistance test to see...read more
