CS505 Final Term Solved Subjective by MS Team

3. Scenario: Running 3 Different Operating Systems

If you need to run 3 different operating systems (e.g., Windows, Linux, macOS) on a single machine, you will need 3 Virtual Machines (VMs). Each VM will have its own OS, running independently on a hypervisor (Type 1 or Type 2).

4. Uses of VirtualBox

•  Running multiple operating systems on one computer
•  Testing and development environments
•  Learning and practicing Linux, Windows, or macOS
•  Creating snapshots and backups of VMs
•  Cross-platform compatibility (Windows apps on Linux, etc.)

5. ESXi Related Questions

 What is ESXi?

o ESXi is a Type 1 Hypervisor by VMware used for server

 How does ESXi manage resources?

o ESXi allocates CPU, RAM, storage, and network resources to VMs.

 What are the key features of ESXi?

o Supports multiple VMs, offers high availability, and provides centralized management.

 What is vCenter Server in ESXi?

o A tool used to manage multiple ESXi hosts in a data center.

6. Hyper-V Related Questions

 What is Hyper-V?

o A Type 1 Hypervisor by Microsoft for virtualization of Windows and Linux VMs.

 How do you enable Hyper-V?

o Go to Control Panel → Turn Windows Features On/Off → Select Hyper-V → Restart.

 What is the difference between Hyper-V and VMware ESXi?

o Hyper-V is Microsoft-based, while ESXi is VMware-based; both provide virtualization but differ in features and licensing.

 What are the three types of Hyper-V virtual switches?

o External, Internal, and Private switches for different network configurations.

Q1. If a Virtual Machine (VM) is created and another VM is built on top of it, where will ESXi allocate resources from?

o ESXi will allocate resources from the physical host machine. However, running a VM inside another VM (Nested Virtualization) can reduce performance due to resource overhead.

Q2. What is VirtualBox?

o VirtualBox is a Type 2 Hypervisor developed by Oracle that allows users to run multiple virtual machines on a host OS.

Q3. Containers – Which important software is not part of it?

o A full operating system is not part of a container. Containers share the host OS kernel and do not require a separate OS instance like Virtual Machines.

4. VMware Related Questions

o What is VMware? → A company that provides virtualization and cloud computing solutions. o What is VMware ESXi? → A Type 1 Hypervisor used for server

o What is VMware Workstation? → A Type 2 Hypervisor used for desktop virtualization.

Long Questions

1. Para Virtualization vs. Full Virtualization (Comparison Table)

2. Four Demerits of Containers

o Security Risks – Containers share the host OS, making them vulnerable to security breaches.
