Which option in the chrony configuration file changes the initial interval of polls to a NTP server in order to speed up the initial synchronization?
Answer: A
Explanation:
The option in the chrony configuration file that changes the initial interval of polls to a NTP server in order to speed up the initial synchronization is iburst. The iburst option allows chronyd to send four requests to the server at intervals of 2 seconds or less, instead of the interval specified by the minpoll option, which is usually
64 seconds. This way, chronyd can make the first update of the clock shortly after start1. The iburst option is recommended for all servers, especially if the network connectivity is not reliable1.
The other options are not valid or do not have the same effect as iburst. The quickstart option does not exist in the chrony configuration file. The fast option is used to specify a fast initial correction of the system clock, but it does not change the polling interval1. The fsync option is used to enable or disable synchronization of the system clock to the real-time clock (RTC) every 11 minutes1. The flood option is used to enable a mode of operation where chronyd sends a burst of requests to the server at a high rate, which can be useful for testing or initial synchronization of a very inaccurate clock1.

NEW QUESTION # 181
Which of the following commands can be used to convert text files in one character encoding to another character encoding?
Answer: B
Explanation:
The command that can be used to convert text files in one character encoding to another character encoding is:
iconv: this command can convert text files from one form of encoding to another, such as UTF-8, ISO-8859-1, ASCII, etc. To use this command, you need to specify the input encoding, the output encoding, and the file name. For example, to convert a file named input.txt from ISO-8859-1 to UTF-8, you can run:
iconv -f ISO-8859-1 -t UTF-8 input.txt
The output will be printed to the standard output, which can be redirected to another file or piped to another command. You can also use the -o option to specify the output file name. For example, to convert the same file and save the output to output.txt, you can run:
iconv -f ISO-8859-1 -t UTF-8 -o output.txt input.txt
To list all the supported encodings, you can use the -l option. For example, to see all the encodings that start with UTF, you can run:
iconv -l | grep UTF
The iconv command is part of the GNU libc package and is available on most Linux systems. The full path of the command is /usr/bin/iconv.
The other options are incorrect because:
cat: this command can concatenate and print files to the standard output, but it does not perform any encoding conversion. It can be used to display the contents of a text file, but it will not change the encoding of the file.
convert: this command can convert image files from one format to another, such as PNG, JPEG, GIF, etc. It is part of the ImageMagick suite of tools and is not related to text encoding conversion.
dd: this command can copy and convert data from one source to another, such as files, devices, or pipes. It can perform some conversions, such as changing the case of letters, swapping bytes, or converting between ASCII and EBCDIC, but it does not support common text encodings such as UTF-8 or ISO-8859-1.
utf2utf: this is not a valid command on Linux. There is no such tool that can convert between different UTF encodings.

NEW QUESTION # 182
After configuring printing on a Linux server, the administrator sends a test file to one of the printers and it fails to print. What command can be used to display the status of the printer's queue? (Specify ONLY the command without any path or parameters.)
Answer:
Explanation:
lpqusrbinlpqlpstatusrbinlpstat
Explanation:
The command lpq can be used to display the status of the printer's queue on a Linux server. The lpq command is part of the cups-bsd package, which provides the Berkeley commands for CUPS (Common UNIX Printing System), the standard printing system for Linux. The lpq command shows the status of a specified printer or the default printer if none is specified. It also lists the jobs that are queued for printing, along with their job IDs, owners, sizes, and names12. For example, to display the status of the printer lp1, we can use the following command:
$ lpq -P lp1
lp1 is ready
Rank Owner Job File(s) Total Size
active user1 123 test.txt 1024 bytes
1st user2 124 report.pdf 2048 bytes
The output shows that the printer lp1 is ready, and that there are two jobs in the queue, one of which is active and the other is waiting. The output also shows the owners, job IDs, file names, and sizes of the jobs. To display the status of all printers, we can use the -a option:
$ lpq -a
lp1 is ready
Rank Owner Job File(s) Total Size
active user1 123 test.txt 1024 bytes
1st user2 124 report.pdf 2048 bytes
lp2 is ready
no entries
The output shows that there are two printers, lp1 and lp2, and that lp2 has no entries in the queue. To display more information about the jobs, such as the priority, submission time, and status, we can use the -l option:
$ lpq -l -P lp1
lp1 is ready
Rank Owner Job File(s) Total Size
active user1 123 test.txt 1024 bytes
priority 50 Apr 27 10:00 processing since Apr 27 10:01
1st user2 124 report.pdf 2048 bytes
priority 50 Apr 27 10:05 waiting for lp1
The output shows that the jobs have the same priority, and that the first job is processing while the second job is waiting. The lpq command can be useful for troubleshooting printing problems, such as checking if the printer is ready, if there are any stuck or failed jobs, or if there are any conflicts or delays in the queue34.

NEW QUESTION # 184
Which commands can you use to change a user's account aging information? (Choose THREE correct answers.)
Answer: A,D,E
Explanation:
The commands that can be used to change a user's account aging information are:
usermod: this command can modify various user account properties, including the password expiration date, the account expiration date, the minimum and maximum password age, the password warning period, and the password inactivity period. To use this command, you need to specify the option and the value for the property you want to change, followed by the username. For example, to set the password expiration date for the user test to February 11, 2022, you can run:
usermod -e 2022-02-11 test
To view the current account aging information for a user, you can use the -l option with the usermod command. For example, to view the information for the user test, you can run:
usermod -l test
passwd: this command can change the password of a user account, as well as some password aging options. To use this command, you need to specify the username and the option for the property you want to change. For example, to change the password of the user test, you can run:
passwd test
To set the maximum password age for the user test to 90 days, you can run:
passwd -x 90 test
To view the current password aging information for a user, you can use the -S option with the passwd command. For example, to view the information for the user test, you can run:
passwd -S test
chage: this command can change the user password expiry and aging information, such as the password expiration date, the account expiration date, the minimum and maximum password age, the password warning period, and the password inactivity period. To use this command, you need to specify the option and the value for the property you want to change, followed by the username. For example, to set the account expiration date for the user test to February 11, 2022, you can run:
chage -E 2022-02-11 test
To view the current account aging information for a user, you can use the -l option with the chage command. For example, to view the information for the user test, you can run:
chage -l test
The other options are incorrect because:
chattr: this command can change the file attributes on a Linux file system, such as making a file immutable, append-only, or undeletable. It has nothing to do with user account aging information.
chsh: this command can change the login shell of a user account, such as bash, zsh, or ksh. It has nothing to do with user account aging information.
