Which of the following is a concern associated with virtualization?
A.
The physical footprint of servers could decrease within the data center.
B.
Performance issues with the host could impact the guest operating systems.
C.
Processing capacity may be shared across multiple operating systems.
D.
One host may have multiple versions of the same operating system.
The Answer Is:
B
This question includes an explanation.
Explanation:
A concern associated with virtualization is that performance issues with the host could impact the guest operating systems, which are the operating systems that run on virtual machines within the host. For example, if the host has insufficient memory, CPU, disk space, or network bandwidth, it could affect the performance and availability of the guest operating systems and the applications running on them. The physical footprint of servers could decrease within the datacenter, processingcapacity may be shared across multiple operating systems, and one host may have multiple versions of the same operating system are not concerns associated with virtualization, but rather benefits or features of virtualization that can help reduce costs, improve efficiency, and enhance flexibility.
