What is a feature a hypervisor?
What is a feature a hypervisor?
A . Provides a VMM that manages all VMS on a clustered compute system
B. Isolates the VMS on a single compute system
C. Provides a VMM that manages all VMS on a single compute system
D. Isolates the physical resources of a single compute system
Answer: C
Explanation:
A hypervisor is a layer of software that runs directly on top of a physical server and provides a virtualization layer. It allows multiple virtual machines (VMs) to run on the same physical hardware, sharing the underlying resources such as CPU, memory, and storage. The hypervisor isolates the VMs from each other and provides a virtual machine monitor (VMM) that manages the virtual machines’ access to physical resources. The VMM is responsible for managing the VMs’ creation, configuration, and removal, as well as their access to the physical resources of the host system. T

Which set of factors govern the overall performance of a hard disk drive?
Which set of factors govern the overall performance of a hard disk drive?
A . Seek time
Rotational latency Data transfer rate
B. Seek time
Rotational latency Bandwidth
C. Seek time
Rotational latency RAID level
D. Seek time
Rotational latency
I/O operations per second
Answer: A
Explanation:
Seek time, Rotational latency, and Data transfer rate are the three factors that govern the overall performance of a hard disk drive (HDD). Seek time is the time required by the read/write head to move to the correct location on the disk, rotational latency is the time required by the disk platter to rotate to bring the desired sector under the read/write head, and data transfer rate is the speed at which data can be transferred between the disk and the buffer (or cache) memory [1]. Bandwidth, RAID level, and I/O operations per second are not factors that govern HDD performance.
