A systems administrator downloads an application's source files, compiles the application, and installs it per the application's installation instructions. When trying to run the application, the system states:
$ occmd
bash: occmd: command not found...
Running the locate command shows it does exist in the following location:
/opt/occmd/bin/occmd
Which of the following should the administrator do to allow the command to run properly?
(Choose two.)
A. mv /opt/occmd ~/ && ln -s ~/occmd/bin/occmd ./occmd
B. echo "export PATH=$PATH:/opt/occmd/bin" >> ~/.bashrc
C. cd /opt/occmd/bin && chmod +x ./occmd && restorecon -rv *
D. sudo ln -s /opt/occmd/bin/occmd /usr/local/bin/occmd
E. echo "#!/bin/bash ${which occmd}" > /usr/bin/occmd.sh
F. sudo mv /opt/occmd/bin/occmd /etc/bin/
正解：B、D

A Linux administrator needs to create an image named sda.img from the sda disk and store it in the /tmp directory. Which of the following commands should be used to accomplish this task?
A. dd of=/dev/sda if=/tmp/sda.img
B. dd --of=/dev/sda --if=/tmp/sda.img
C. dd if=/dev/sda of=/tmp/sda.img
D. dd --if=/dev/sda --of=/tmp/sda.img
正解：C
解説：
Explanation
The command dd if=/dev/sda of=/tmp/sda.img should be used to create an image named sda.img from the sda disk and store it in the /tmp directory. The dd command is a tool for copying and converting data on Linux systems. The if option specifies the input file or device, in this case /dev/sda, which is the disk device.
The of option specifies the output file or device, in this case /tmp/sda.img, which is the image file. The command dd if=/dev/sda of=/tmp/sda.img will copy the entire disk data from /dev/sda to /tmp/sda.img and create an image file. This is the correct command to use to accomplish the task. The other options are incorrect because they either use the wrong options (--if or --of instead of if or of) or swap the input and output (dd of=/dev/sda if=/tmp/sda.img or dd --of=/dev/sda --if=/tmp/sda.img).

質問 # 27
While inspecting a recently compromised Linux system, the administrator identified a number of processes that should not have been running:
Which of the following commands should the administrator use to terminate all of the identified processes?
A. killall -9 -upload*.sh"
B. skill -9 "upload*.sh"
C. pkill -9 -f "upload*.sh"
D. kill -9 "upload*.sh"
正解：C
解説：
The pkill -9 -f "upload*.sh" command will terminate all of the identified processes. This command will send a SIGKILL signal (-9) to all processes whose full command line matches the pattern "upload*.sh" (-f). This signal will force the processes to terminate immediately without giving them a chance to clean up or save their state. The kill -9 "upload*.sh" command is invalid, as kill requires a process ID (PID), not a pattern. The killall -9 "upload*.sh" command is incorrect, as killall requires an exact process name, not a pattern. The skill
-9 "upload*.sh" command is incorrect, as skill requires a username or a session ID (SID), not a pattern. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 15: Managing Memory and Process Execution, page 470.
