Question 1

You are testing out a new DHCP server and want to make sure that it does not interfere with your current network. What option would you use to configure your network adapter using VMware workstation?
A) NAT
B) bridged
C) host-only
D) internal

Accepted Answer

Using the host-only option will allow the virtual machine to communicate only with the host computer and not with any other devices on the network, which is ideal when testing out a new DHCP server. This prevents interference with the current network setup and allows for isolated testing. The other options (NAT, bridged, internal) may allow communication with devices on the existing network and could potentially interfere with network operations.

Question 2

What is the native file-sharing protocol in Linux?
A) SMB
B) NFS
C) NSF
D) SMP

Accepted Answer

NFS (Network File System) is the native file-sharing protocol in Linux. It allows remote access to files and directories over the network and is used by many Linux distributions as the standard way of sharing files among systems. SMB (Server Message Block) is also a file-sharing protocol, but it is primarily used by Windows systems. NSF and SMP are incorrect options.

Question 3

What is a partial copy of a VM that is used to restore it to a previous state?
A) snapshot
B) clone
C) hypervisor
D) host computer

Accepted Answer

A snapshot is a partial copy of a VM that captures its state at a specific point in time. It can be used to restore the VM to that previous state if needed, making it a useful tool for testing and troubleshooting. Cloning creates a full duplicate of the VM, whereas a snapshot is only a partial copy. Hypervisor and host computer are not relevant to the definition of a snapshot.

Question 4

Which edition of Windows Server 2008 includes support for up to 64 processors and provides unlimited virtual instances?
A) Web Server 2008
B) Standard Edition
C) Enterprise Edition
D) Datacenter Edition

Accepted Answer

The Datacenter Edition of Windows Server 2008 includes support for up to 64 processors and provides unlimited virtual instances, making it the best choice for large-scale virtualization and data center deployments. The Web Server 2008 edition is intended for hosting web pages and is limited to a single processor, while the Standard and Enterprise editions can support up to 4 and 8 processors, respectively.

Question 5

Which of the following virtualization products provides hosted virtualization?
A) Citrix XenServer
B) VMware vSphere
C) Microsoft Hyper-V
D) VMware Workstation

Accepted Answer

VMware Workstation provides hosted virtualization, which allows a virtualization layer to run on top of a host operating system. The other options (A, B, and C) provide bare-metal virtualization, which allows the virtualization layer to run directly on the hardware without the need for a host operating system.

Question 6

Which common e-mail protocol allows the user to access messages, yet still have them stored on the server?
A) SMTP
B) IMAP
C) POP3
D) SNMP

Accepted Answer

IMAP (Internet Message Access Protocol) allows the user to access and view messages on the server and keep them stored there, instead of downloading and removing them from the server like POP3 (Post Office Protocol version 3). SMTP (Simple Mail Transfer Protocol) is used to send email, while SNMP (Simple Network Management Protocol) is used for network management purposes.

Question 7

In Windows, you use Task Manager to view the processes running on your computer. What do you use to view the running processes on some Linux systems?
A) resource monitor
B) terminal manager
C) performance manager
D) system monitor

Accepted Answer

In some Linux systems, the tool used to view running processes is called the "system monitor". This is similar to the Task Manager in Windows. Options A, B, and C are not commonly used terms for this task on Linux systems.

Question 8

Which of the following is not a function typically provided by the centralized management of a server-based network?
A) account management
B) user authentication
C) security policy management
D) protocol analysis

Accepted Answer

Protocol analysis typically falls under the purview of network management rather than server management. The other options (account management, user authentication, and security policy management) are typical functions of centralized management of a server-based network.

Question 9

What is the process called that grants or denies a user's access to network resources?
A) authentication
B) acceptance
C) authorization
D) admission

Accepted Answer

The process that grants or denies a user's access to network resources is called authorization. Authentication is the process of verifying a user's identity, while acceptance and admission do not relate to this process.

Question 10

Which part of the OS provides users and applications with an interface to manipulate files?
A) kernel
B) services
C) processes
D) file system

Accepted Answer

The file system is responsible for managing files and directories and provides an interface for users and applications to manipulate them. The kernel manages system resources such as memory and hardware devices, services perform specific tasks related to the OS, and processes are instances of running programs.

Question 11

Windows Server 2008 R2 can be installed only on a 64-bit system.

Accepted Answer

Windows Server 2008 R2 only supports 64-bit hardware architectures and does not have a 32-bit version. Therefore, it can only be installed on a 64-bit system.

Question 12

When a disk is formatted, it is impossible to recover the data that was on the disk..

Accepted Answer

Although formatting a disk may make the data inaccessible, it is still possible to recover the data using specialized data recovery software or services. Formatting simply erases the file system and directory structure, but the actual data may still be present on the disk until it is overwritten by new data.

Question 13

What storage solution involves a third-party company that provides off-site hosting of data?
A) network-attached storage
B) cloud-based storage
C) network accessed appliance
D) storage area network

Accepted Answer

The storage solution that involves a third-party company that provides off-site hosting of data is cloud-based storage. Network-attached storage (A) refers to a storage device connected to a network to provide storage to multiple devices. Network accessed appliance (C) is not a commonly used term in the context of storage solutions. Storage area network (D) is a dedicated network to provide high-speed access to storage devices, but it does not involve off-site hosting of data by a third-party company.

Question 14

What are the chunks called into which the available storage space on a disk drive is broken?
A) bytes
B) sectors
C) bits
D) segments

Accepted Answer

The available storage space on a disk drive is broken into sectors, which are each assigned a unique identifier for easy retrieval of data. Bytes are the smallest unit of measurement for digital information, bits are the individual digits of binary code, and segments are larger divisions of a program's code.

Question 15

Virtualization is designed for testing and development purposes only.

Question 18

One critical difference between a client OS and a server OS is the addition of directory services on some server OSs.

Accepted Answer

Directory services, such as Active Directory, are commonly found on server operating systems to centrally manage users, computers, and resources on a network. While some client operating systems may have basic directory capabilities, they typically do not offer the full range of features and functionalities of a server OS.

Question 19

What method does the CPU use to divide its computing cycles between more than one process?
A) context switching
B) process switching
C) time slicing
D) thread slicing

Accepted Answer

The method used by CPU to divide its computing cycles between more than one process is time slicing, which is the technique of dividing the CPU time between multiple processes or threads. The CPU switches between the processes at regular intervals, giving each process a fair share of computing time. This ensures that no process or thread is monopolizing the CPU time, and all processes are running efficiently. Context switching and process switching are related concepts but do not address the division of computing cycles between processes, and thread slicing is not a recognized term in computer science.

Question 20

Older OSs first used what type of multitasking, which allowed a process to monopolize the CPU's time until the process had completed its own task?
A) contextual
B) cooperative
C) preemptive
D) precocious

Accepted Answer

Cooperative multitasking allowed a process to hold onto the CPU until it had completed its task and voluntarily yielded control to other processes.
