Question 1

What is a partial copy of a VM that is used to restore it to a previous state?

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. Cloning creates a complete copy of a VM, and a hypervisor is the software that allows for the creation and management of virtual machines. The host computer is the physical machine that runs the hypervisor and virtual machines.

Question 2

What directory service protocol is used by Active Directory and also supported by Linux?

Accepted Answer

LDAP is the directory service protocol used by Active Directory and also supported by Linux. NFS is a file-sharing protocol, NIS is a legacy directory service protocol, and LEAP is a network authentication protocol.

Question 3

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 typically only found on server operating systems and are used to manage and authenticate network resources and users. Client operating systems typically do not have robust directory service capabilities built in.

Question 4

What is the native file-sharing protocol in Linux?

Accepted Answer

The native file-sharing protocol in Linux is NFS (Network File System), which is a distributed file system protocol that allows multiple hosts to share files over a network. SMB (Server Message Block) is a file-sharing protocol used by Microsoft Windows, and can be used on Linux using Samba. NSF and SMP are non-existent file-sharing protocols.

Question 5

Windows Server 2012 can be installed on a 32-bit system.

Accepted Answer

Windows Server 2012 is only available for 64-bit systems.

Question 6

Which of the following is a function typically provided by the centralized management of a server-based network? (Choose all that apply.)

Accepted Answer

The answer of Which of the following is a function...

Question 7

Virtualization is designed for testing and development purposes only.

Accepted Answer

Virtualization can be used for various purposes including testing and development, production environments, disaster recovery, and more.

Question 8

What type of multitasking did older OSs use,which allowed a process to monopolize the CPU's time until the process had completed its own task?

Accepted Answer

Older OSs used cooperative multitasking, which allowed a process to monopolize the CPU's time until the process had completed its own task. This means that the process could hold onto the CPU for an extended period, even if other processes needed access to it.

Question 9

Which Windows Server 2012 license provides unlimited virtual instances of the OS?

Accepted Answer

Datacenter Edition provides unlimited virtual instances of the OS, whereas the other editions have limitations on the number of virtual instances that can be run.

Question 10

What method does the CPU use to divide its computing cycles between more than one process?

Accepted Answer

The CPU uses time slicing to divide its computing cycles between more than one process. This involves allocating a small time interval, called a time slice or quantum, to each process before switching to the next one. This allows for multiple processes to execute concurrently and improves the overall efficiency and responsiveness of the system.

Question 11

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?

Accepted Answer

The host-only option allows the virtual machine to communicate with the host machine only, and not with the external network, ensuring that the new DHCP server does not interfere with the current network. NAT and bridged options would allow the virtual machine to access the external network which can cause interference, and the internal option would isolate the virtual machine from the network entirely.

Question 12

What is the process called that grants or denies a user's access to network resources?

Accepted Answer

The process that grants or denies a user's access to network resources is called authorization. Authentication is the process of verifying the identity of a user, while acceptance and admission are not commonly used in this context. Therefore, the best choice is C.

Question 13

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

Accepted Answer

Although formatting a disk erases the file system and makes the data inaccessible, it is still possible to recover the data using specialized software or services. Formatting only removes the pointers to the data and does not overwrite the actual data sectors on the disk, which can be recovered by experts.

Question 14

Which common e-mail protocol allows the user to access messages,yet still have them stored on the server?

Accepted Answer

IMAP (Internet Message Access Protocol) allows the user to access their e-mail messages from multiple devices and locations, while still leaving the messages stored on the server. This is different from POP3 (Post Office Protocol version 3), which downloads the messages to the user's device and deletes them from the server. SMTP (Simple Mail Transfer Protocol) is responsible for sending e-mails, and SNMP (Simple Network Management Protocol) is used for managing and monitoring network devices.

Question 15

Which part of the OS provides users and applications with an interface to manipulate files?

Accepted Answer

The file system is the part of the operating system that provides the interface for users and applications to manipulate files. The kernel is responsible for managing system resources, while services and processes are components that work together in the background to support the OS and applications.

Question 16

What are the chunks called into which the available storage space on a disk drive is broken?

Accepted Answer

The available storage space on a disk drive is broken into sectors, which are small subdivisions on the disk where data can be stored. Each sector typically contains 512 bytes of data. Bytes, bits, and segments are other units of measurement for data storage, but they do not specifically refer to the subdivisions on a disk drive.

Question 17

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?

Accepted Answer

System Monitor is the Linux equivalent of Task Manager in Windows. It provides a graphical interface to view and monitor system processes, resource usage, and performance. Other options like resource monitor, terminal manager, and performance manager are not necessarily used to view running processes in Linux.

Question 18

In Windows,you can start the Task Manager by simply right-clicking the taskbar and choosing Start Task Manager.

Accepted Answer

This is a correct statement.

Question 19

Which of the following virtualization products uses a type 2 hypervisor?

Accepted Answer

VMware Workstation is a type 2 hypervisor, which runs on top of an operating system like Windows or Linux. It allows users to create and run multiple virtual machines on a single physical machine. Citrix XenServer, VMware vSphere, and Microsoft Hyper-V are all type 1 hypervisors, which run directly on the physical hardware.

Question 20

What storage solution involves a third-party company that provides off-site hosting of data?

Accepted Answer

Cloud-based storage involves a third-party company that provides off-site hosting of data. This is different from network-attached storage (A) and storage area network (D) which are typically hosted on-premise. Network accessed appliance (C) is not a commonly used storage solution.
