41. If you store mainly large files on a disk, should you use a smaller cluster size or larger cluster size? Why?
ANSWER:
You should use a larger cluster size. If you store mostly large files on the disk, a larger
cluster size usually results in better performance because fewer read/write operations need to
be performed. In addition, smaller cluster sizes can lead to a fragmented disk, in which files
are spread out all over the disk instead of being stored in consecutive locations.
Fragmentation causes many more disk seek operations, which slows file access.

42. What is the System Idle process, and what does its value mean?
ANSWER:
When the operating system is not busy, the kernel schedules the System Idle process with the
CPU time. Therefore, a high value for the system idle process would mean that the CPU is
not busy. A low value would mean that the CPU is busy with other processes.

43. What is a storage area network and why might you use one?
Name:
Class:
Date:
ANSWER:
A storage area network (SAN) is a high-speed, high-cost network storage solution that
largely replaces locally attached drives on servers. SAN technology allows multiple servers
to access an enormous amount of shared storage that appears as locally attached drives from
the server and user’s perspective. This level of centralized storage offers better reliability and
fault tolerance than traditional storage methods. Additionally, because storage is shared
among several servers, power requirements for maintaining these systems are lower than
those needed to maintain several servers with their own locally attached storage.

44. What is a server cluster and what is the difference between a failover cluster and a load-balancing cluster?
ANSWER:
A server cluster is two or more servers configured to operate as a single unit. The most
common types of server clusters are failover clusters and load-balancing clusters. A failover
cluster is used to provide fault tolerance so that if one server fails, the other immediately
takes over its functions with no or little downtime. A load-balancing cluster provides high-
performance computing and data access by spreading the workload among multiple
computers.

45. How do you map a shared folder using the command prompt? Provide an example of mapping a drive letter
H: to a share named myshare on a server named myserver.
ANSWER:
Open a command prompt and enter the command: net use, followed by a space and then
the drive letter that you want to map it to, followed by a colon. Add another space and then
enter the UNC path of the share to be mapped. For example: net use H:
\\myserver\myshare

47. Compare and contrast hosted virtualization versus bare-metal virtualization.
ANSWER:
Hosted virtualization uses a type 2 hypervisor in which the host OS accesses host hardware
on behalf of the guest OS. It’s used mostly for desktop virtualization solutions. Bare-metal
virtualization is used mainly for server virtualization in data centers and uses a type 1
hypervisor.

48. What are two types of isolation that virtualization can provide? Describe them.
ANSWER:
Virtualization can provide application isolation and network isolation. Application isolation
prevents an application running on a virtual machine from conflicting with other applications
running on other VMs or the host computer. Network isolation prevents protocols running on
the virtual network from interfering with other protocols running on the host network; for
example DHCP.
