Exam SY0-701 topic 1 question 226 discussion

B Containerization allows multiple applications or services to run in isolated environments on the same underlying OS. Unlike, virtualization where each VM runs its own OS, containers share the host OS kernel but keep the applications isolated from one another. This significantly reduces the number of operating systems required while maintaining security and isolation between applications.

The correct answer is: B. Containerization Explanation: Containerization allows multiple applications to run on the same operating system kernel while isolating them in separate containers. This approach: Reduces the need for multiple individual operating systems by running applications within lightweight containers. Improves resource efficiency and scalability. Enhances security by isolating containers, limiting the potential impact of a compromised application.

Decommissioning physical servers leads me to believe this is C

If the goal is reducing OS instances and enhancing application-level isolation, containerization is the better answer. If the focus is on replacing physical servers with virtual ones, virtualization might seem plausible but doesn't fully address the isolation and security benefits containerization provides.

While containers are an excellent solution for reducing infrastructure overhead, virtualization is more directly focused on consolidating physical servers into fewer operating systems, which matches the question more precisely.

Virtualization involves creating virtual versions of hardware platforms, operating systems, and storage devices. By implementing virtualization, a company can run multiple operating systems or applications on the same physical server, each in its own virtual machine (VM). This allows for: Reduced number of physical servers needed. Centralized management of multiple OS environments. Efficient use of hardware resources. Isolation of applications for security purposes.

"reduce the number of individual operating systems"

The correct answer is C. Virtualization. Virtualization involves running multiple virtual machines (VMs) on a single physical server, allowing an organization to consolidate multiple operating systems and workloads onto fewer physical servers. This reduces the number of physical machines needed while still providing isolated environments for different applications, services, or operating systems.

Containerization allows fewer Operating Systems. Sometimes this question comes with fewer physical servers, resulting in virtualization. Take steps to ensure you read the question carefully.

B. Containerization - is more appropriate as it allows multiple applications to run on a single OS, whereas virtualization involves running multiple OS on same physical hardware.

B. Containerization like "docker" container.

C. Virtualization Explanation of the MCQ: Virtualization is a technology that allows multiple virtual machines (VMs) to run on a single physical server's hardware. Each VM can run its own operating system and applications, effectively reducing the number of physical servers required and thus the number of individual operating systems managed in a physical sense. By using virtualization, a company can consolidate its server infrastructure, leading to reduced hardware costs, easier management, and potentially enhanced security due to a smaller physical footprint and centralized management.
