Which common e-mail protocol allows the user to access messages, yet still have them stored on the server?
-
SMTP
-
SNMP
-
IMAP
-
POP3
Correct Answer
A. IMAPExplanation
IMAP (Internet Message Access Protocol) is the correct answer because it allows users to access their email messages while keeping them stored on the server. Unlike POP3 (Post Office Protocol version 3), which typically downloads emails to the user's device and removes them from the server, IMAP allows users to view and manage their emails without actually downloading them. This makes it convenient for users who want to access their emails from multiple devices or locations, as the messages remain accessible on the server. SMTP (Simple Mail Transfer Protocol) is used for sending emails, while SNMP (Simple Network Management Protocol) is used for network management, not email retrieval.Rate this question:

When an IP address in the DHCP scope is associated with a specific MAC address, it is considered:
-
Exempt
-
Excluded
-
Static
-
Reserved
Correct Answer
A. ReservedExplanation
When an IP address in the DHCP scope is associated with a specific MAC address, it is considered "Reserved". This means that the DHCP server will always assign the same IP address to the device with that MAC address. This is useful for devices that require a consistent IP address, such as servers or network printers. The reserved IP address will not be assigned to any other device in the network, ensuring that the device with the specific MAC address always receives the same IP address.Rate this question:

Which RAID version is the most efficient using 3 or more drives?
-
7
-
5
-
0 + 1
-
0
-
1
Correct Answer
A. 5Explanation
RAID 5 is the most efficient version when using 3 or more drives. In RAID 5, data is distributed across multiple drives along with parity information, which allows for data redundancy and fault tolerance. This means that if one drive fails, the data can still be reconstructed using the parity information on the remaining drives. RAID 5 also offers good performance as it allows for simultaneous read and write operations across multiple drives, making it an efficient choice for data storage and retrieval.Rate this question:

When dealing with permissions in Linux, what are the three user types that can be assigned permissions? (Choose three.)
-
Class
-
Owner
-
Group
-
Creator
-
Object
-
Other
Correct Answer(s)
A. Owner
A. Group
A. OtherExplanation
In Linux, permissions can be assigned to three user types: Owner, Group, and Other. The Owner refers to the user who owns the file or directory and has the highest level of control over it. The Group refers to a group of users who have similar permissions on the file or directory. The Other refers to all other users who are not the owner or part of the group. These three user types allow for granular control over who can access and modify files and directories in Linux.Rate this question:

Which of the following are the correct permissions for the command chmod 574?
-
R-xrw-r--
-
Rwxr-xrw-
-
R--rwxr-w
-
Rwxr-xr--
-
R-xrwxr--
Correct Answer
A. R-xrwxr--Explanation
The correct answer is "r-xrwxr--". The command "chmod 574" sets the permissions for a file or directory. The first digit "5" represents the owner's permissions, which are "r-x" (read and execute). The second digit "7" represents the group's permissions, which are "rwx" (read, write, and execute). The third digit "4" represents the others' permissions, which are "r--" (read only). Therefore, the correct permissions for the command "chmod 574" are "r-xrwxr--".Rate this question:

What level of RAID does not provide fault tolerance?
-
1
-
3
-
0
-
5
Correct Answer
A. 0Explanation
RAID 0 does not provide fault tolerance. In RAID 0, data is striped across multiple drives without any redundancy or parity information. This means that if one drive fails, all the data stored on that drive will be lost. RAID 0 is primarily used for performance improvement, as it allows for faster read and write speeds by distributing data across multiple drives. However, it does not provide any protection against drive failures, making it the only RAID level that does not offer fault tolerance.Rate this question:

-
5
-
4
-
2
-
3
Correct Answer
A. 4Explanation
RAID 1+0, also known as RAID 10, combines mirroring (RAID 1) and striping (RAID 0) techniques. In RAID 1+0, data is mirrored across multiple pairs of disks and then striped across those mirrored pairs. This provides both redundancy and improved performance. To implement RAID 1+0, a minimum of four disks are required. The data is mirrored across two sets of disks, and then those mirrored sets are striped together. Therefore, the correct answer is 4.Rate this question:
