NEW QUESTION # 13
While using vi as superuser. the attempt to save a file while quitting the editor leads to an error indicating that the file is read-only. How can the file permissions be overridden to save the edits to the file and quit the editor?
- A. : wq!
- B. : ql
- C. : fwq
- D. : fw!
- E. : wq
Answer: A
Explanation:
Explanation
The wq! command is used to save a file and quit the vi editor, even if the file is read-only. The w command means write, the q command means quit, and the ! command means force. By combining these commands, the vi editor will override the file permissions and save the changes to the file, then exit the editor. The other options are either invalid syntax or do not force the write operation. For example, wq will save and quit only if the file is writable, ql will quit without saving, and fw! will force write but not quit. References:

NEW QUESTION # 14
Which configuration file defines the order of the name resolution methods used on a NetBSD system'?
- A. /etc/resolv.conf
- B. /etc/hosts
- C. /etc/nsswitch.conf
- D. /etc/rc.conf
- E. /etc/named
Answer: C
Explanation:
Explanation
The /etc/nsswitch.conf file defines the order of the name resolution methods used on a NetBSD system. It specifies the sources and their priority for various databases, such as hosts, services, protocols, etc. The sources can be files, DNS, NIS, or other services. For example, the following line in /etc/nsswitch.conf indicates that the hosts database should be looked up first in the /etc/hosts file, then in the DNS server, and finally in the NIS server:
hosts: files dns nis

NEW QUESTION # 15
Which command shows the current user's group memberships?
- A. who
- B. groups
- C. group
- D. ident
- E. showuser
Answer: B
Explanation:
Explanation
The groups command is used to show the current user's group memberships on BSD systems. The command prints the names of the primary and secondary groups that the user belongs to, separated by spaces. The primary group is the one that is assigned to new files and directories created by the user. The secondary groups are the ones that grant additional permissions or access to the user. For example, the output of groups for a user named alice might look like this:
alice wheel staff
This means that alice's primary group is alice, and her secondary groups are wheel and staff. The wheel group is typically used for granting administrative privileges, such as using the su or sudo commands. The staff group might be used for granting access to certain resources or directories that are shared by a group of users.
The other options are either invalid commands or do not show the user's group memberships. For example, group is not a valid command, ident is used to query an ident protocol server, showuser is not a valid command, and who is used to show who is logged on the system.

grep "non [-] disclosure" legalfile
- A. non-disclosure only
- B. disclosure only
- C. disclosure and non-disclosure only
- D. non-disclosure only
- E. non-disclosure and non-disclosure Only
Answer: E
Explanation:
Explanation
The command grep "non [-] disclosure" legalfile matches the lines in the file that contain the pattern non [-] disclosure, where the brackets indicate a character class that matches either a space or a dash. Therefore, the lines that contain non-disclosure or non - disclosure are matched by the command, while the line that contains disclosure only is not matched. The file has two lines that contain non-disclosure, so the correct answer is E. non-disclosure and non-disclosure Only. References:

Which of the following commands is used to set the FreeBSD security level?
- A. slct1
- B. security
- C. secleve1
- D. sysct1
- E. setleve1
Answer: D
Explanation:
Explanation
The sysctl command is used to set and get kernel state variables, including the FreeBSD security level. The security level is a variable named kern.securelevel, which can have values from -1 to 3, with higher values indicating more restrictions. The security level can only be increased, not decreased, unless the system is rebooted or in single-user mode. The security level affects various operations, such as loading kernel modules, changing immutable flags on files, and modifying device nodes12 References: 1:

NEW QUESTION # 19
How many /28 IPv4 subnets can be created within a /24 IPv4 prefix?
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
Answer: D
Explanation:
Explanation
A /24 IPv4 prefix provides 256 IP addresses, which is the number of addresses in one octet (2^8). A /28 subnet has 16 IP addresses (2^4). To calculate how many /28 subnets can fit into a /24 prefix, divide the total number of addresses in the /24 prefix by the number of addresses in a /28 subnet: 256 / 16 = 16. However, since each subnet has network and broadcast addresses that cannot be used for hosts, the actual number of usable subnets is less. In practice, you can create 16 subnets, each with 14 usable IP addresses for hosts.

Which directories contain start scripts for services on FreeBSD? (Choose TWO correct answers.)
- A. /var/boot/rc.d/
- B. /usr/rc.d/
- C. /etc/red/
- D. /boot/red/
- E. /usr/local/etc/rc.d/
Answer: B,E
Explanation:
Explanation
The directories that contain start scripts for services on FreeBSD are /usr/rc.d/ and /usr/local/etc/rc.d/. The
/usr/rc.d/ directory contains the system-provided scripts for the base system services, such as cron, sshd, syslogd, etc. The /usr/local/etc/rc.d/ directory contains the scripts for the additional services installed from ports or packages, such as apache, mysql, nginx, etc. These scripts follow the BSD rc.d framework, which allows for fine-grained control and customization of the startup process. The scripts are invoked by the main
/etc/rc script, which sources the /etc/rc.conf file for configuration options

NEW QUESTION # 26
Assuming a umask of 022, what are the default permissions in octal mode of the newly created files?
- A. 0
- B. 022
- C. 1
- D. 2
- E. 3
Answer: C
Explanation:
Explanation
The umask command in BSD is used to set default permissions for files or directories the user creates1. The umask value is permissions to deny, taken off whatever permissions would be given by default2. The default permission values for files are 666 (rw-rw-rw-), meaning read and write for user, group, and others3. The umask value of 022 means that the permissions to deny are 022 (-w-w-), meaning write for group and others. To calculate the default permissions for newly created files, we need to subtractthe umask value from the default permission value, using bitwise AND operation4. For example:
666 - 022 = 644 rw-rw-rw- - -w-w- = rw-r-r-
Therefore, the default permissions for newly created files with a umask of 022 are 644 (rw-r-r-), meaning read and write for user, and read for group and others.

NEW QUESTION # 28
What command creates a new directory? (Specify ONLY the command without any path or parameters.)
Answer:
Explanation:
mkdir
Explanation
The command mkdir (short for make directory) creates a new directory with the specified name. The command takes one or more arguments, which are the names of the directories to be created. If the name contains spaces or other special characters, it should be enclosed in quotes. For example, mkdir "My Documents" creates a directory named My Documents. The command also accepts some options, such as -p, which creates the parent directories if they do not exist, or -m, which sets the permissions of the new directory.
For example, mkdir -p -m 755 /usr/local/bin creates the directory /usr/local/bin and its parent directories /usr and /usr/local, and sets the permissions of /usr/local/bin to 755 (read, write and execute for the owner, read and execute for the group and others). References:

What does S l represent in the following lines from a Bourne shell script:
#! /bin/sh
cp SI 52
- A. A function.
- B. The shebang.
- C. A control operator.
- D. An environmental variable.
- E. A positional parameter.
Answer: E
Explanation:
Explanation
The command cp SI 52 in the Bourne shell script copies the file named by the value of SI to the file named 52.
The SI is a positional parameter that represents the first argument passed to the script when it is executed.
Positional parameters are numbered from 1 to 9, and can be accessed by using the dollar sign $ followed by the number. For example, $1 is the first positional parameter, $2 is the second, and so on. Therefore, the SI in the script is equivalent to $1, and it represents the first argument passed to the script. The correct answer is D.
A positional parameter. References:

NEW QUESTION # 31
Which command sends the contents of the file myconfigfile by email to me@mycompany. com?
- A. cat myconfigfile I mail [email protected]
- B. mail [email protected] I cat myconfigfile
- C. mail myconfigfile -r [email protected]
- D. mail [email protected] > cat myconfigfile
- E. cat myconfigfile > [email protected]
Answer: A
Explanation:
Explanation
The cat command is used to concatenate and display files. The mail command is used to send and receive mail messages. The pipe symbol (I) is used to redirect the output of one command to the input of another command.
Therefore, the command cat myconfigfile I mail [email protected] sends the contents of the file myconfigfile by email to [email protected]. The cat command reads the file and displays its contents to the standard output, which is then piped to the mail command, which reads the standard input and sends it as a mail message to the specified address. The mail command also prompts the user to enter a subject line and optionally some additional headers for the message. Alternatively, the subject line can be specified by the -s option of the mail command. For example, the command cat myconfigfile I mail -s "My config file" [email protected] sends the same message with the subject "My config file". References:
