What is the difference between inline-block and block display properties in CSS?
- Inline elements flow in a line, and only take as much width as necessary. Block elements start on a new line and take the full width available.
- Inline-block elements combine the features of both inline and block elements. They flow in a line and can have a width set.
- Block elements are used for inline-level content, while inline-block elements are used for block-level content.
- Inline elements are used for block-level content, while block elements are used for inline-level content.
The correct option explains that inline-block elements combine features of both inline and block elements, allowing them to flow in a line and have a set width.

How does containerization help in the deployment process?
- Containerization allows applications to be deployed without any dependencies.
- Containerization ensures that applications run consistently across various environments.
- Containerization reduces the size of the application, leading to faster deployment times.
- Containerization simplifies the process of deploying applications by encapsulating them along with their dependencies.
Containerization simplifies the deployment process by encapsulating applications along with their dependencies, libraries, and runtime environments into containers. These containers are lightweight and portable, ensuring that applications run consistently across different environments, from development to production. This eliminates issues related to compatibility and dependency conflicts, streamlining the deployment process.
What is a Pod in the context of Kubernetes?
- A Pod is a group of containers that share networking and storage resources.
- A Pod is a node in a Kubernetes cluster responsible for scheduling containers.
- A Pod is a single container that encapsulates an application and its dependencies.
- A Pod is a virtual machine instance in a Kubernetes cluster.
In the context of Kubernetes, a Pod is the smallest deployable unit. It represents a group of one or more containers that share networking and storage resources, such as IP address and filesystem. Pods are the basic building blocks of Kubernetes applications and serve as the logical host for containers. They enable co-located, tightly-coupled containers to work together as a single application.
