Question 3

Which of the following virtualization products uses a type 2 hypervisor?
A) Citrix XenServer
B) VMware vSphere
C) Microsoft Hyper-V
D) VMware Workstation

Accepted Answer

VMware Workstation is a type 2 hypervisor, also known as a hosted hypervisor, which runs on top of an existing operating system. The other options listed use type 1 hypervisors, also known as bare metal hypervisors, which run directly on the host's hardware without an underlying operating system.

Question 4

What directory service protocol is used by Active Directory and also supported by Linux?
A) NFS
B) NIS
C) LDAP
D) ICMP

Accepted Answer

Active Directory uses LDAP as its directory service protocol and LDAP is also supported by Linux, making it the best choice. NFS is a file sharing protocol, NIS is another directory service protocol but is not as widely used as LDAP, and ICMP is a network protocol used for error reporting and diagnostics.

Question 5

Which of the following is NOT a typical function of a file system?
A) disk drive space organization
B) schedules processes and manages memory
C) hierarchical storage method
D) provides secure access to files

Accepted Answer

Scheduling processes and managing memory is typically the function of an operating system, not a file system. The other three options are all common functions of a file system.

Question 6

Which protocol does Windows use by default for file sharing?
A) SMTP
B) SMB
C) FTP
D) SNMP

Accepted Answer

Windows uses Server Message Block (SMB) protocol by default for file sharing. It allows files and printers to be shared between computers on a network.

Question 7

How does a CPU perform multitasking?
A) using time division multiplexing
B) using asynchronous bus management
C) using time slicing and context switching
D) using process-driven frequency hopping

Accepted Answer

A CPU performs multitasking by using time slicing and context switching. Time slicing allows the CPU to share its processing time among multiple tasks by dividing its time into smaller intervals and allocating each interval to a different task. Context switching allows the CPU to quickly switch between tasks and save their current state so that it can return to them later without losing progress. Asynchronous bus management and process-driven frequency hopping are not commonly used methods for CPU multitasking, and time division multiplexing has limited effectiveness in modern CPUs.

Question 8

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 is taken at a specific point in time. It can be used to restore the VM to its previous state if necessary. Cloning is a different process that creates a separate copy of a VM that can run independently. Hypervisor and host computer are not specific to the concept of a partial copy of a VM.

Question 9

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

Accepted Answer

When a disk is formatted, the data is not completely erased, but rather the file system on the disk is reset, making the data inaccessible through normal means. However, specialized software and techniques can be used to attempt to recover the data.

Question 10

You have been asked to create a file that will contain a series of Windows command-prompt commands that automate the creation of a VPN client that connects to your company VPN server. What type of file should you create?
A) computer program
B) executable file
C) batch file
D) macro file

Accepted Answer

A batch file is a script file containing commands that are processed by the Windows command prompt. It can be used to automate a series of commands and create a VPN client that connects to your company VPN server. It is a text file with a .bat file extension.

Question 11

For enterprise servers, or servers accessed around the clock, SATA disks are preferred over SAS disks.

Accepted Answer

SAS disks are preferred over SATA disks for enterprise servers or servers accessed around the clock due to their faster data transfer rates, higher reliability, and better performance in heavily loaded environments.

Question 12

Which of the following is a service NOT usually found on a client operating system?
A) DNS
B) file sharing
C) DHCP
D) directory service

Accepted Answer

Directory services are typically found on server operating systems rather than client operating systems. They provide a centralized location for network information and facilitate the management of users, computers, and other resources within a network. Client operating systems, on the other hand, usually include services like DNS, file sharing, and DHCP for network connectivity and resource access.

Question 13

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

Accepted Answer

The native file-sharing protocol in Linux is NFS (Network File System). It is specifically designed for Unix derivative operating systems like Linux and allows file sharing between Linux systems. NFS provides faster access to shared files and simplifies the management of shared resources. SMB (Server Message Block) is a protocol used by Windows and also supported by Linux for file sharing, but it is not native to Linux. NSF and SMP are not valid file-sharing protocols.

Question 14

Which feature of bare-metal virtualization products allows virtual resources to be allocated on demand to meet application requirements?
A) server consolidation
B) snapshots
C) live migration
D) dynamic provisioning

Accepted Answer

Dynamic provisioning allows virtual resources to be allocated on demand to meet application requirements. Server consolidation and snapshots are not related to this feature, and live migration is a separate feature that allows virtual machines to be moved between physical hosts without downtime.

Question 15

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?
A) contextual
B) cooperative
C) preemptive
D) multiplexed

Accepted Answer

Cooperative multitasking allowed a process to monopolize the CPU's time until the process had completed its task. Contextual and preemptive multitasking are more advanced forms of multitasking that allow for more efficient usage of system resources. Multiplexed operating systems allow for multiple users to access and use a system simultaneously.

Question 16

In order to multitask, a computer must have two or more processors.

Accepted Answer

Multitasking can be achieved on a computer with a single processor by using time-sharing techniques, where the processor switches rapidly between running different tasks. This gives the illusion of simultaneous multitasking.

Question 17

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) external
B) bridged
C) host-only
D) switched

Accepted Answer

The best option would be to use the host-only option, as it allows for communication between the virtual machine and the host machine, but does not allow for access to the external network. This means that the new DHCP server can only affect the virtual network and not interfere with the current network.

Question 18

The kernel is a software layer that sits just above the computer hardware.

Accepted Answer

The kernel is a low-level software layer that interfaces with the computer hardware, providing basic services for other software to build upon.

Question 19

A type 1 hypervisor runs directly on the host computer's hardware.

Accepted Answer

A type 1 hypervisor, also known as a bare metal hypervisor, runs directly on the host computer's hardware, whereas a type 2 hypervisor runs on top of a host operating system.

Question 20

What unit is used to divide the storage space on a disk drive?
A) bytes
B) sectors
C) bits
D) segments

Accepted Answer

The storage space on a disk drive is divided into sectors. Each sector is a small section of storage space typically measuring 512 bytes.
