Discuss
Answer: (c).Backup and recovery, integration to directory services, security management Explanation:Examples of services that can be managed using host operating system administration tools in operating system-based virtualization include backup and recovery, integration to directory services, and security management.
Q72.
What is a concern related to performance in operating system-based virtualization?

a.

The availability of hardware IT resources

b.

The compatibility of virtual servers with different operating systems

c.

The reliance on hardware drivers

d.

The processing overhead introduced by the virtualization layer and host operating systems

Discuss
Answer: (d).The processing overhead introduced by the virtualization layer and host operating systems Explanation:A concern related to performance in operating system-based virtualization is the processing overhead introduced by the virtualization layer and host operating systems. This overhead can negatively affect system performance.
Q73.
How does operating system-based virtualization handle hardware-related calls from guest operating systems?

a.

It routes hardware-related calls directly to the physical hardware

b.

It translates hardware-related calls into software instructions

c.

It allows guest operating systems to access hardware directly

d.

It requires guest operating systems to install additional drivers for hardware access

Discuss
Answer: (b).It translates hardware-related calls into software instructions Explanation:In operating system-based virtualization, hardware-related calls from guest operating systems are translated into software instructions that interact with the virtualization layer and host operating system.
Q74.
What is the main advantage of hardware-based virtualization over operating system-based virtualization?

a.

It eliminates the need for virtualization software

b.

It enables compatibility with a wide range of operating systems

c.

It provides a more advanced user interface

d.

It allows virtual servers to interact with hardware directly without intermediary action from the host operating system

Discuss
Answer: (d).It allows virtual servers to interact with hardware directly without intermediary action from the host operating system Explanation:The main advantage of hardware-based virtualization over operating system-based virtualization is that it allows virtual servers to interact with hardware directly without requiring intermediary action from the host operating system. This generally makes hardware-based virtualization more efficient.
Q75.
What is the role of a hypervisor in hardware-based virtualization?

a.

It provides a user interface for managing virtual servers

b.

It handles hardware management functions and establishes a virtualization management layer

c.

It replaces the need for hardware device drivers

d.

It acts as an operating system for virtual servers

Discuss
Answer: (b).It handles hardware management functions and establishes a virtualization management layer Explanation:In hardware-based virtualization, a hypervisor handles hardware management functions and establishes a virtualization management layer. It interacts with the host hardware and manages the virtual servers.
Q76.
What is a potential issue with hardware-based virtualization regarding compatibility?

a.

Lack of support for virtualization software

b.

Incompatibility with a wide range of operating systems

c.

Device drivers and support software need to be compatible with the hypervisor

d.

Compatibility with the host operating system

Discuss
Answer: (c).Device drivers and support software need to be compatible with the hypervisor Explanation:A potential issue with hardware-based virtualization is that device drivers and support software need to be compatible with the hypervisor. Since the hypervisor interacts directly with the host hardware, compatibility with hardware components is crucial.
Q77.
What type of management functions do virtualization infrastructure management (VIM) tools provide?

a.

Server hardware configuration

b.

Guest operating system installation

c.

Resource management for virtual IT resources

d.

Physical network configuration

Discuss
Answer: (c).Resource management for virtual IT resources Explanation:Virtualization infrastructure management (VIM) tools provide resource management functions for virtual IT resources. They help manage and automate administration tasks related to virtual servers and other virtualized IT resources.
Q78.
What is the purpose of a centralized management module (controller) in a virtualization infrastructure management (VIM) system?

a.

To replace the role of a hypervisor

b.

To provide a user interface for virtual servers

c.

To handle hardware management functions

d.

To manage and coordinate virtualization management across virtual IT resources

Discuss
Answer: (d).To manage and coordinate virtualization management across virtual IT resources Explanation:The purpose of a centralized management module (controller) in a virtualization infrastructure management (VIM) system is to manage and coordinate virtualization management across virtual IT resources. The controller serves as a central point for managing and automating various administrative tasks related to virtual servers and other virtualized IT resources. It helps ensure efficient resource utilization, scalability, and overall management of the virtualized environment.
Q79.
What is the primary concern with poorly formulated virtualization plans?

a.

Excessive resource pooling

b.

Incompatibility with hardware

c.

High performance overhead

d.

Lack of portability

Discuss
Answer: (c).High performance overhead Explanation:Poorly formulated virtualization plans can lead to excessive performance overhead, impacting the system's efficiency.
Q80.
Which strategy is used to mitigate performance overhead in virtualization?

a.

Hardware virtualization

b.

Resource pooling

c.

Para-virtualization

d.

Elastic scalability

Discuss
Answer: (c).Para-virtualization Explanation:Para-virtualization is a technique that reduces the processing overhead of guest operating systems, although it requires adapting the guest operating system to a modified software interface.
