For this discussion, you will be assessing the following help desk ticket below from Chikako (connectivity issue). Use the CompTIA 6-step troubleshooting process below to help figure out the connectivity issue.

CompTIA 6-Step Troubleshooting Process:

1. Identify the problem.
2. Establish a theory of probable cause.
3. Evaluate the theory to determine the actual cause.
4. Establish a plan of action to resolve the problem and implement the solution.
5. Verify full system functionality and if applicable, implement preventative measures.
6. Document findings, actions, and outcomes.

[Forwarded Ticket] Assignee: Open Raised by: Chikako Sato, buyer, Tokyo office Category: Connectivity Issue Priority: High Message: THIS IS URGENT. Chikako called me at the help desk, saying his computer is up and working but cannot log into the domain. He has a meeting in 25 minutes and needs files and the PowerPoint for the meeting! I cannot take over their machine remotely nor can I ping it. Can you help? -Jen

There are multiple potential solutions. You can pick one of the four below or have a different potential solution of your own.

• bad cable
• bad NIC
• switch failure
• DHCP server down

Focus on only one of the potential solutions for stepping through the six steps of the troubleshooting process. Answer the first four out of the six steps in your post. For the third CompTIA step, what would it take to prove your theory correct or incorrect? Example: If I do X and Y happens, then that is the issue. If Z happens, it is something else.

During this semester, we reviewed a number of areas in risk and risk management, risk assessment and the way in which companies can try and minimize their risk exposure. Getting closer to your dissertation, you will need to choose a topic in your first dissertation class, DSRT-736, so it is essential to start preparing. This week, let us take a look at some topics to consider, and by the end of the week, we could have several ideas for dissertation topics. Since you have already examined several research articles, another way would be to examine previous dissertations in these areas. Visit the University of Cumberland’s library, go to the Dissertation Database, and locate an interesting topic on risk, a model, framework, some approach to minimizing risk, etc. Here are some pointers that will help critically evaluate some viable topics:

• Is the topic attainable for a first-time dissertation student?
• Is the problem rooted in the literature?
• Is the research empirical, i.e., is there a survey, is there an interview guide, has the data been analyzed via some statistical tool?
• Is there a theoretical model or framework discussed?

Discuss the topic, the problem the model has been used in the research, and any present findings.

Do not read the entire dissertation, as the abstract and chapter one introduction should give a clear understanding of the research.

Directions

1. Rewrite your program from Unit 5 so that it reads strings from the file and builds the list courses instead of defining all the data as part of your program itself.
   The file aspect should be the only thing that you change – the rest of the program logic should remain the same.
   Note that when reading from a file, each line contains a newline character, ‘n’, which will cause your table to be double spaced. See the string method .strip() in Chapter 9.5 for an easy way of fixing this.
2. Add your test cases from the program in Unit 5 at the end of the text file.
   You can edit the text file with Notepad, or IDLE, or Thonny or any text editor on your system.

1. Write a reflection in the comment box answering the following questions:
   1. In a sentence or two, what did you learn?
   2. In a sentence or two, what did you like about this project?
   3. In a sentence or two, what did you find confusing or would like to see done differently regarding this project?
   4. In a sentence or two, if you had another hour or two, what would you like to add to the project or how would you do things differently?

Getting Started

As you continue following this running case study, be sure to record answers for each instruction. Your results may be used in future assignments.

Upon successful completion of this assignment, you will be able to:

Describe functional requirements.

Explain why identifying user stories and use cases is the key to defining functional requirements.

Differentiate between the different information gathering techniques.

Examine the role of leadership in project management.

Instructions

• Read Running Case Study “On the Spot Courier Services” at the end of Chapter 4.
• Record your answers to questions 1–4 at the end of the case study in a Word document, titled “WS2 Class Diagram”. It should contain the finalized class diagram, including all your classes, attributes, primary keys, relationships, and multiplicity constraints.
• Read Running Case Study “On the Spot Courier Services” at the end of Chapter 5.

Record your answer to question 1 at the end of the case study in a Word document, titled “WS2 Request a Pickup—Pickup a Package”.

When you have completed the assignments, save a copy for yourself and submit a copy to your instructor using the Assignment submission link. You should include the two Word documents, “WS2 Class Diagram” and “WS2 Request a Pickup—Pickup a Package”.

1. get the structure of the gss_sm dataframe. What is the data type of race, sex, region and income? What do the levels refer to? 
2. create a graph that shows a count of religious preferences grouped by region
3. turn the region counts in percentages
4. use dodge2() to put the religious affiliations side by side within regions
5. show the religious preferences by region, faceted version with the coordinate system swapped
6. using pipes show a 10 random instances of the first six columns in the organdata data set
7. create a scatterplot of donors vs. year
8. create a faceted set of line chart graphs showing donors for year for different countries
9. create a boxplot of the data with coordinates swapped (because the mean is calculated in every boxplot and because R throws an error when trying to calculate means when there is missing data, add the na.rm = TRUE parameter to remove the NA’s).  
10. Replace the boxplot with points
11. jitter the points
12. reduce the amount of jitter
13. using organdata, create a table of summary statistics by country called by_country (show the mean of donors, gdp, health, roads, cerebvas, and the standard deviation of donors)
14. what is the cerebvas column referring to?
15. What conclusions can you draw from the previous plot?
