virtualization

How does Type 1 hypervisor prioritize tasks for different virtual machines?

• By allocating equal resources to all VMs
• By optimizing based on VM operating system needs
• Through a predefined scheduling algorithm within the hypervisor
• By monitoring and adapting to dynamic workload changes

Why did the introduction of Type 2 hypervisor revolutionize desktop virtualization?

• It enabled virtualization without dedicated hardware
• It improved VM to VM communication significantly
• It drastically reduced latency in network simulation
• It allowed hypervisor operation without software assistance

In what way does a bare-metal hypervisor enhance security compared to a hosted hypervisor?

• By isolating VMs within a common user space
• By requiring minimal direct user interaction
• By leveraging direct hardware access without a host OS layer
• By using predefined security policies per VM

Analyze the impact of using a hosted hypervisor in a performance-critical application environment.

• Increases system speed due to lightweight design
• Decreases performance because of resource sharing with host OS
• Optimizes resource allocation through real-time adaptability
• Enhances application performance through faster direct I/O operations

What is a significant advantage of using a nested virtualization architecture with Type 1 hypervisors?

• Improved overall physical server power consumption
• Seamless deployment on older hardware
• Enhanced capability to run hypervisors within VMs
• Simplified network traffic management

How would the implementation of a paravirtualized hypervisor impact guest OS performance?

• Improves guest OS performance by reducing overhead
• Reduces need for security updates in guest OS
• Increases latency between hypervisor and guest OS
• Complicates VM resource allocation

Why did traditional data centers start migrating to virtualized environments with hypervisors?

• To enable greater physical isolation of servers
• To ensure consistent power usage and cooling
• To reduce hardware costs via shared resources
• To implement simpler disaster recovery solutions

In what way does a hypervisor interface lead to improved system reliability?

• By ensuring all VM processes run in parallel
• By duplicating tasks across multiple nodes
• By isolating VMs to prevent one VM's crash from affecting others
• By utilizing a single-threaded operation model

Analyze the impact of implementing hypervisors with extensive hardware virtualization support.

• Increases dependency on specific software applications
• Minimizes CPU usage due to task offloading
• Relies less on hardware-specific instructions
• Reduces need for recurring calibration of virtual environments

Why is it important for a hypervisor to have VM snapshot capability?

• To improve real-time processing speed
• To reduce the likelihood of network isolation
• To allow recovery and rollback to previous states easily
• To ensure VM hardware compatibility
