Hands-On Project – Systemctl Command and Managing Runlevels Option 2
This Critical Thinking Assignment focuses on using the Systemctl, runlevel, and init commands that were discussed in this week’s classroom materials. Following the steps in this assignment will demonstrate how these commands can be used from the shell prompt of Linux to manage the boot process and restart options of a test Linux virtual machine (VM). This report will document the process of completing each step and include screenshots where applicable to demonstrate the results of each step.
Systemctl
In order to complete the steps in this week’s critical thinking assignment, the listed commands will all need to be run from a shell prompt within the test Linux VM that was

This command asked for elevation and requires the user to enter the root password to complete the command. Upon successful authentication, the system then reboots into rescue mode. Booting the system in this mode allows you to run a different less complete Linux installation instead of booting from the hard drive (Fedora, 2017). This ability can be a very powerful tool that enables a user to repair a boot loader or recover files. The end user must be very careful in this mode however, because you could cause even further damage or cause data loss if you do not know what you are doing. My system rebooted into the GUI and I was able to login normally. I then opened a shell prompt and used the runlevel command to show I was booted into level 1 which is rescue mode. This result is shown in screenshot 5 and 6. I then ran step five which was to use the “systemctl start default.target” command to return the system to the default boot target. Screenshot 7 shows that the command was entered but never completed even after waiting several minutes. I was able to gracefully reboot the VM using the GUI option. After rebooting the VM which was step 6, I verified the system was running in default target mode which in runlevel 5. I did this by running the runlevel command in a shell prompt. The output can be seen in screenshot …show more content…
To accomplish this, I ran the “init 5” command from a shell prompt. Again, I was prompted for elevated privileges and the system rebooted. I verified that I was still in default target mode by running the “runlevel” command and verifying this.
Conclusion
The focus of this week’s Critical Thinking Assignment involved getting familiar with the systemctl, runlevel, and init commands within Linux. By following the steps outlined, I was able to test the effects of each of these commands and document how they can be used to view information about the installation and successfully boot into the different modes offered within Linux. These commands are very useful and demonstrate the power of using the shell prompt to manage the Linux operating
When a computer is turn on, a bootstrap will complete an automated chain of functions that gradually increase access to system controls and hardware. The OS will then detect what it and other programs need from the hardware, applying them quickly.

In this study, the professor asked 15 students in his Introductory Psychology class to volunteer to take the smart pill at the start of the semester. The other 15 students in the class who did not volunteer did not take the pill. This was not random assignment because this subject was not an unbiased division, and the professor didn’t create equal groups; therefore, it could affect the result. In general, volunteers do better than non-volunteers because volunteers have more motivation than the people who didn’t volunteer. For example, in the “tutoring study”, people who signed up for tutoring were doing much better than the people who did not sign up for tutoring because the people who sign up care about their grade; on
While the media might not directly contribute to discrimination, the media is undoubtedly a significant aspect of modern day society that influences how people think about racial issues (Royce, 2009, p. 1, 17). Many people claim that racism no longer exists; however, the minorities’ struggle with injustice is ubiquitous. Whites are attempting to keep blacks and other minority families locked into an impoverished political and economic position by using various tactics to isolate them, such as mass incarceration that stems from the War on Drugs. The New Jim Crow helps us in seeing how history is repeating itself and how to legalized discrimination among the blacks and Hispanics by implementing the mass incarceration.

Buddhist believes that all people are reborn over and over again until they reach spiritual enlightenment and then Nirvana. In Buddhism good deeds are rewarded by receiving a better rebirth. Karma dictates a person’s rebirth including their financial state, appearance, class, health, species, and intelligence. Buddhist ultimate goal is to strive for Nirvana. Nirvana is the state that exists beyond the cycle of reincarnation, freedom from Karmic suffering, and provides a state of heavenly paradise.
Rate each of the following statements as TRUE or FALSE. Justify your answer with an example or explanation to prove and illustrate your understanding. DO NOT OMIT THIS PART OF THE TEST. True/False answers can be guessed. But when you defend your answer by example or explanation, you demonstrate not only your memory and understanding but also that you can apply what you have learned. The first question is answered for you.
In this paper I will be answering specific questions about a critical thinking exercise located in the assigned text book. The questions that will be answered include: discussing the problem of the scenario, who the problem belongs to, the actions nurse Witte should take and the mode of communication she should use. Then I will discuss how she can provide a clear message, and to whom the message should be send to first, as well as, all the people that should informed. Lastly, I will explain the type of leadership and management strategies that would be best utilized.
Overcoming resistance to change: By having an open mind and welcoming, not necessarily accepting, many new ideas.
I agree these are all great options for informing and allowing the client to understand what happened and that it is required of him to pay the balance before things are escalated to higher authorities. I believe the phone call method and sending the letter should be done first before moving on to any other method. Those two methods listed will either cause the patient to fix the issue or like stated above may take for the clinic to use the other methods as you

In Chapter 3, there were 12 areas of bias spread across the 3 areas of heuristics. The main theme of the text was to prove that we are predisposed to certain outcomes. As we make important decisions we rely on our memory, or a number of past events, or even ignoring facts. Overall, we are biased in many ways when it comes to making decisions, or predicting outcomes of a particular event.
3. Meaning/Purpose - In the biblical/Christian Worldview our purpose in life is to build a relationship with God through his son Jesus Christ. We are also to spread the message of Jesus to others so that they may be saved as well. As Buddhists do not believe in God, they believe our purpose in life is to eliminate our suffering and stop the cycle of reincarnation.
Following is a report completed for the executives of Frist World Bank Savings and Loan, with the objective to provide information on how to secure a Linux platform using installed commands and other available open source software. Explained are the use of bastion hosts to secure architecture design as well as best practices to mitigate security risks to a Linux server using suitable software management plan. Layered secure is demonstrated as well as a described backup, recovery, and incident response plan in our Linux architecture.
Three of the most important types of Linux security technologies are Security Enhanced Linux (SELinux), chroot jail, and iptables. This security measures aide in the subversion of theft and malicious activity. We will discuss these items in depth to address who created them and for what reason. Along with how these technologies changed the operating system to enforce security, and the types of threats that these security systems are design to eliminate.
