What is a key difference between containers and virtual machines in terms of resource usage?

Containers share the host operating system kernel, while virtual machines each include a full guest operating system

Both containers and virtual machines use the same amount of memory because they both isolate applications

Containers require a hypervisor, while virtual machines do not

Virtual machines share the host kernel, while containers each have their own kernel

A company has a legacy application that requires a specific version of a library that conflicts with the library version required by a newer application. Both applications must run on the same server. The company wants to avoid modifying the applications. Which approach is most appropriate?

Run each application in a separate container with its own dependencies

Run both applications directly on the host OS

Run both applications in the same container with both library versions

A company is considering moving from physical servers to virtual machines to reduce hardware costs. They have a mix of applications, some of which are legacy and require specific hardware dongles. Which consideration is most important when planning the migration?

The storage type (HDD vs SSD) on the host.

The hypervisor's support for USB passthrough to virtual machines.

The amount of RAM in the physical host.

The network bandwidth of the physical host.

A software company wants to provide a consistent development environment to all its developers, ensuring that the same code runs identically on every machine. The developers use different operating systems (Windows, macOS, Linux). Which approach best achieves this?

Provide each developer with a virtual machine image

Use containers with the application and its dependencies

Use a configuration management script to set up each machine

Create a shared network drive with the source code

An organization runs a batch processing job that takes 30 minutes to complete. The job is CPU-intensive and does not require persistent state. The organization wants to run this job on a shared server without affecting other workloads. Which approach is most appropriate?

Create a virtual machine with dedicated CPU cores

Run the job directly on the host OS

Use a separate physical server for the job

Run the job in a container with CPU limits
