Answer: B,D

NEW QUESTION # 15
You must add an additional swap device and you add this entry to /etc/fstab:
/.swapfile none swap defaults 0 0
Examine these commands and output:
# dd if=/dev/zero of=/.swapfile bs=1024 count=1048576
1048576+0 records in
1048576+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 4.32499 s, 248 MB/s
# swapon -a
swapon: /.swapfile: insecure permissions 0644, 0600 suggested.
swapon: /.swapfile: read swap header failed
Which two actions must you perform to add this swap device?

A. Use a physical disk partition type of 82 (Linux swap).
B. Execute swapon -all.
C. Initialize the .swapfile file by using the mkswap command.
D. Execute swapon -L swapfile /.swapfile after adding a label.
E. Change defaults to user in the /etc/fstab entry.
F. Assign a label to the .swapfile file by using the swaplabel command.

Answer: C,F

Explanation:
To use a file as swap space, it must first be initialized with themkswapcommand. Theddcommand creates an empty file, butmkswapformats this file to be used as swap space. This command writes the necessary swap header to the file, making it recognizable by the system as a valid swap area.
Explanation of Answer D:After initializing the swap file withmkswap, you can optionally assign a label to the swap file using theswaplabelcommand. This is not strictly required, but it can be useful for identifying swap files, especially if you are using multiple swap devices.

NEW QUESTION # 16
Examine this command:
# auditctl -w /etc/passwd -p w -k pass
Which two statements are true upon execution?

A. An audit rule is defined that creates a log entry every time /etc/passwd is read.
B. A write occurs to /etc/audit/rules.d/audit.rules.
C. An audit rule is defined with the keyword pass.
D. An audit is defined that creates a log entry every time a write occurs to /etc/passwd.
E. A write occurs to /etc/audit/audit.rules.

Answer: C,D

NEW QUESTION # 17
Examine the contents of the /etc/exports file on an NFS server:
/status *(rw,async)
/usr/shared/tools *(all-squash,anonuid=501,anongid=501,ro)
/projects/big *(ro) pteam(rw)
The NFS server exports /usr/shared/tools to NFS clients. Which statement is true?

A. All clients can mount /usr/shared/tools read-only and NFS explicitly maps all requests to the UID and GID of the privileged local 501 user.
B. All clients can mount /usr/shared/tools read-only and NFS explicitly maps all requests to the UID and GID of the unprivileged local 501 user.
C. All clients can mount /usr/shared/tools read-only and NFS ignores the directives defined by the anonuid and anongid options.
D. All clients can mount /usr/shared/tools read-only and all-squash overrides explicit mapping of the UID and GID defined by anonuid and anongid.
E. All clients except those with a local 501 user can mount /usr/shared/tools read-only.

Answer: B

NEW QUESTION # 18
Examine /etc/anacrontab:
SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# the maximal random delay added to the base delay of the jobs
RANDOM_DELAY=45
# the jobs are started during the following hours only
START_HOURS_RANGE=3-22
# period in days delay in minutes job-identifier command
1 5 dailyjob nice run-parts /etc/cron.daily
7 25 weeklyjob nice run-parts /etc/cron.weekly
@monthly 45 monthlyjob nice run-parts /etc/cron.monthly
Which two statements are true about the jobs scheduled in this file?

A. Jobs defined in this anacrontab file are randomly delayed by up to 51 minutes.
B. Scripts run by the third job are delayed between 45 and 90 minutes.
C. Scripts run by the first job are delayed between 11 and 45 minutes.
D. Scripts run by the second job are delayed between 31 and 70 minutes.
E. Jobs defined in this anacrontab file can be executed between 15:00 and 22:00

Answer: B,E

Explanation:
Understanding the anacrontab Entries:
The /etc/anacrontab file contains the following variables and job definitions:
SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# the maximal random delay added to the base delay of the jobs
RANDOM_DELAY=45
# the jobs are started during the following hours only
START_HOURS_RANGE=3-22
# period in days delay in minutes job-identifier command
1 5 dailyjob nice run-parts /etc/cron.daily
7 25 weeklyjob nice run-parts /etc/cron.weekly
@monthly 45 monthlyjob nice run-parts /etc/cron.monthly
Variables Explained:
* RANDOM_DELAY=45
* Specifies that arandom delaybetween 0 and 45 minutes is added to the base delay of each job.
* START_HOURS_RANGE=3-22
* Jobs are allowed to start only between03:00 (3 AM)and22:00 (10 PM).
Job Delays Calculated:
* First Job (dailyjob):
* Base Delay:5 minutes
* Random Delay:0 to 45 minutes
* Total Delay:5 + (0 to 45) =5 to 50 minutes
* Second Job (weeklyjob):
* Base Delay:25 minutes
* Random Delay:0 to 45 minutes
* Total Delay:25 + (0 to 45) =25 to 70 minutes
* Third Job (monthlyjob):
* Base Delay:45 minutes
* Random Delay:0 to 45 minutes
* Total Delay:45 + (0 to 45) =45 to 90 minutes
Option B: Jobs defined in this anacrontab file can be executed between 15:00 and 22:00
* Explanation:
* The START_HOURS_RANGE=3-22 setting allows jobs to start between03:00 and 22:00.
* Therefore, it's true that jobscan be executed between 15:00 (3 PM) and 22:00 (10 PM).
* This statement is correct because the specified time range falls within the allowed start hours.
* Oracle Linux Reference:
* OracleLinux 8: Scheduling Tasks- Section on "Anacron Configuration Files":
"The START_HOURS_RANGE variable defines the time window during which Anacron jobs can run." Option C: Scripts run by the third job are delayed between 45 and 90 minutes.
* Explanation:
* The third job (monthlyjob) has abase delay of 45 minutes.
* With a RANDOM_DELAY of up to 45 minutes, thetotal delaybefore execution is between45 and 90 minutes.
* Therefore, this statement is accurate.
* Oracle Linux Reference:
* OracleLinux 8: Scheduling Tasks- Section on "Understanding Anacron Job Delays":
"Each job's delay is calculated by adding its defined delay to a random value between 0 and RANDOM_DELAY." Why Other Options Are Not Correct:
* Option A:Scripts run by the first job are delayed between 11 and 45 minutes.
* Explanation:
* The first job (dailyjob) has a total delay between5 and 50 minutes(5-minute base delay plus up to 45 minutes random delay).
* Therefore, the statement specifying11 to 45 minutesis incorrect.
* Option D:Jobs defined in this anacrontab file are randomly delayed by up to 51 minutes.
* Explanation:
* The maximum random delay is set by RANDOM_DELAY=45, so the random delay is up to45 minutes, not 51.
* Therefore, this statement is false.
* Option E:Scripts run by the second job are delayed between 31 and 70 minutes.
* Explanation:
* The second job (weeklyjob) has a total delay between25 and 70 minutes(25-minute base delay plus up to 45 minutes random delay).
* The statement specifies a delay between31 and 70 minutes, which is incorrect because the minimum delay is 25 minutes.
Conclusion:
Options B and C are correct based on the configuration specified in /etc/anacrontab. They accurately reflect the possible execution times and delays for the jobs defined.
