Question 1

In large multidomain networks, assigning resource permissions to users throughout Active Directory requires using global or ____ groups.
A)default
B)guest
C)universal
D)domain

Accepted Answer

Universal groups are recommended for assigning resource permissions in large multidomain networks because they can be used across all domains in the forest. Global groups are limited to the domain in which they are created, making them less efficient in a multidomain environment. Default and guest groups are not appropriate for assigning resource permissions.

Question 2

Windows Server OSs come with two predefined accounts: the Administrator account, for management duties, and the ____ account, for users who have no personal account in the local domain.
A)Public
B)Guest
C)Anonymous
D)User

Accepted Answer

The Guest account is designed for users who have no personal account in the local domain, and it comes with limited permissions and privileges. This account is typically used for temporary or occasional users who need to access resources on the server.

Question 3

In Linux, you use the ____ command-line program to create a password for a user.
A)cpasswd
B)chpasswd
C)mkpasswd
D)passwd

Accepted Answer

The "passwd" command is used to create a password for a user in Linux.

Question 4

In Linux, most account details on password expiration are taken from the / e t c / ____ and / e t c /default/ useradd files.
A)passwd
B)shadow
C)login.defs
D)users.defs

Accepted Answer

The account details on password expiration in Linux are taken from the login.defs file, which provides configuration for the shadow password suite. The passwd file contains the encrypted passwords for user accounts, and the shadow file contains additional information and controls access to passwords. The useradd files in /etc/default/ provide default values for user creation, but do not specifically address password expiration. Therefore, the best choice is C) login.defs.

Question 5

In Linux, a variety of log files are maintained that report on system and user activity, many of which can be found in the ____ directory.
A)/etc/log
B)/var/log
C)/log
D)/dev/log

Accepted Answer

The log files in Linux are typically stored in the /var/log directory, which includes both system logs and logs of user activity. The /etc/log and /log directories do not exist by default, and the /dev/log directory is related to device drivers rather than system and user activity logging.

Question 6

After a Linux user is created, the account can be deleted with the rmuser command.

Accepted Answer

The correct command to delete a Linux user account is actually "userdel", not "rmuser".

Question 7

Of the five types of backup, normal, copy, and daily backups are most useful as part of a regular backup schedule.

Accepted Answer

The most useful types of backups for a regular schedule are typically full, incremental, and differential backups, not normal, copy, and daily backups.

Question 8

After a Linux user is created, the user's properties can be changed with the ____ command.
A)usermod
B)usrmod
C)chuser
D)chusr

Accepted Answer

The usermod command is used to modify user account information, including properties such as login name, home directory, shell, and group membership. The other options listed (usrmod and chuser/chusr) are not valid Linux commands.

Question 9

In addition to the groups to which you can assign them, users are added to certain groups automatically when they log on, and you can't change these memberships. Microsoft refers to these groups as "____".
A)default groups
B)default identities
C)special groups
D)special identities

Accepted Answer

Special identities are groups to which users are automatically added when they log on, and these memberships cannot be changed.

Question 10

The ____ Linux command is used to create a new user or update default new user information.
A)usradd
B)usrmod
C)useradd
D)usermod

Accepted Answer

useradd is the command used to create a new user or update default new user information.

Question 11

Disk duplexing is disk mirroring in which each disk has its own controller, thereby protecting the system from controller failures as well as disk failures.

Accepted Answer

Disk duplexing, also known as RAID 1, involves creating an exact copy (mirror) of data on two separate disks, each with its own controller. This redundancy protects against both disk and controller failures.

Question 12

In Windows, ____ groups have preassigned rights that apply to all group members.
A)default
B)template
C)universal
D)domain

Accepted Answer

Default groups in Windows have preassigned rights and permissions that apply to all members of the group.

Question 13

If a Linux user account must be disabled, the usermod command can be used with the -L option,which inserts "____" at the beginning of the password to indicate a disabled account.
A)#
B)!
C)@
D)*

Accepted Answer

The "!" symbol in Linux represents a disabled account. When the usermod command is used with the -L option, it sets the password field to "!" which indicates that the account is locked and cannot be used for login.

Question 14

A(n)____ is any system component or resource that's accessible to a user program in Windows, such as the CPU on a system or the IP protocol.
A)event
B)object
C)counter
D)class

Accepted Answer

An object is any system component or resource that's accessible to a user program in Windows. The other options (event, counter, class) are not comprehensive enough to include all system components or resources.

Question 15

In Windows, a(n)____ is a certain part of an object that tracks an aspect of its behavior.
A)event
B)object
C)counter
D)class

Accepted Answer

In Windows, a counter is a certain part of an object that tracks an aspect of its behavior, such as CPU usage or network traffic.

Question 16

After a Linux account is created, it's not enabled until a password is created.

Accepted Answer

The user account is not enabled until a password is set.

Question 17

You can draw conclusions about server activity by observing details of ____, such as connections between network devices and the server, the rate at which connections to the server are made, and how those connections are broken, whether by a normal logoff, an error, or a server timeout.
A)spoofed packets
B)data reads and writes
C)server sessions
D)server events

Accepted Answer

Server sessions provide information on the connections made to the server, their rates, and how they are terminated, making it possible to draw conclusions about server activity. Spoofed packets, for example, may be used to launch attacks or bypass security measures, but they do not reflect server activity. Data reads and writes are also relevant but only provide information on data access. Server events, on the other hand, may refer to a wide range of server operations and are not specific enough to draw conclusions about server activity.

Question 18

In Windows, a ____ profile allows a user's settings and files to be applied to any computer he or she logs on to.
A)roaming
B)shared
C)domain
D)network

Accepted Answer

A roaming user profile allows a user's personalized settings and files to be stored on a server and applied to any computer they log into within the same domain. This provides a consistent experience for the user regardless of which specific computer they are using. Shared profiles are typically used for multiple users to access the same settings and files on a single computer, while domain and network profiles are broader concepts that involve multiple computers and systems within an organization.

Question 19

Called disk striping, RAID 2 distributes data over two or more disks.

Accepted Answer

Disk striping is a characteristic of RAID 0, while RAID 2 uses disk-level striping with dedicated Hamming-code parity.

Question 20

The two most popular fault-tolerant disk configurations are disk mirroring (or duplexing)and disk striping with parity.

Accepted Answer

Disk mirroring and disk striping with parity are the two most popular fault-tolerant disk configurations.
