CIS142 – 5.7 – The Troubleshooting Process – Corey Adams
Advantages
The divide and conquer approach can be more effective than both top-down and below-ground solutions. Both top-down and base-up methods work the same way. These methods can either be applied at the OSI model's top or bottom. Each layer is examined to find the problem, and then it is rectified. Divide and conquer is a more natural way to think. First, we examine the symptoms that a device displays. We then use this information for a hypothesis, and we test it.
Description of the user
One skill I learned early in my career was the ability to translate technical jargon into elementary
school speech. This does not mean customers do not understand technical terms. You have probably tried to communicate with a mechanic, a doctor and a lawyer using technical terms. Without walking in front of the door, we would not be able see the root cause. It can be frustrating. This is true for both the professional and the person seeking assistance. While the customer may be trying awfully hard to explain their problem clearly, it is possible that they are not communicating what they mean. While it may seem trivial to customers to refer to cables as wires, we know that this is a significant issue.
Troubleshooting
CompTIA's troubleshooting method is something I use daily at work as well as in my private life. This is what I also teach my nieces and nephews. The problem is explained, and I then help them create a solution. My niece was able to ride a motorcycle-style moped. It would not start unless you applied the throttle. I do not have a lot of experience with mechanics, so I used the CompTIA as well as the bottom-up method. I did a physical inspection to find that the carburetor's line was not connected. I tried to connect it, but it was too small. I decided to loosen

the end of the cable to make it more manageable. Unfortunately, it was hard to get both sides on. It was not an ideal solution. There are no parts available for this vehicle. I had the cable taken apart and it sent to a local parts shop. They offered me a longer, more similar option. Although the diameter of the cable was slightly larger than the original hose's, it was still longer and allowed for a more secure installation.

Before you start to use virtual machines, make sure that the network settings are correct. To make sure everything is running smoothly, I first verify the configurations for each virtual machine. I would first verify that the network configurations of both devices are correct. Then, I would look for plausible causes. Next is to look at security settings. I start with firewalls that connect virtual machines to the network. This could either be a local firewall or an actual firewall that provides security settings to the network.
Network Traffic and Certificate Safety
If you cannot communicate via the internet for certain traffic and no other traffic, that means there is a security setting. Check your firewall settings. Once you have checked that, you can proceed to the destination. Traffic is sent to the network to verify that it is working. Certificates are like passwords. They expire after a specific time. To ensure high security, it is important to replace expired certificates. Expiration of certificates can lead to authentication problems for both individuals and services.

Wireless sensor networks (WSNs) are an example of a network that may facilitate communication. Sensing nodes in WSNs communicate with one another and a central hub. The computing resources and storage space of a sensor node are limited. Think of an algorithm that can be solved by separating it into smaller chunks. To solve these subproblems at separate sensor nodes, would you prefer use divide and conquer or dynamic programming? Please be brief in your writing.

Exercise 2:
We have two lists of the same length representing sensors data. The second sensor is supposed
to be redundant, so that the two lists should have identical values. But for practical reason there
are going to be small differences. In order to evaluate the quality of data collected with our
sensors, we want to calculate the total absolute values of differences between the values. For
instance:
Sensor 1 reading:
Sensor 2 reading:
15, -4, 56, 10, -23
14, -9, 56, 14, -23
1,
Differences:

The total absolute differences is 1+5+0+4+0 = 10

differences between the values

The OSI model, on the other hand, says that there should be a certain number of layers, but most real computer systems don't follow this rule. The way computer systems work at their core is what has led to the current situation. If you can, try making the product with less pieces. How would it be bad to cut down on the total number of layers?

There are many sensors on a wind turbine, based on each sensor's reading many alerts are generated as (start, end). For easier monitoring, our customer is asking to raise alerts on the turbine level instead of on each sensor. If any sensor is having an alert, there should be an alert for the entire wind turbine. Suppose the alerts created with two sensors readings are [(0,3),(5,10),(1,4),(10,15)], then the turbine level alert should be [(0,4),(5,15)]. Return the alerts sorted by the start timestamp. If there is no alert from the sensor level, return an empty array []. Code needs to be in Python?

A computer uses virtual memory, and a new solid-state drive (SSD) as space for paging. Refer to the last ppt file. In the case presented there, the hard disk drive (HDD) required 25 ms to read in a page, and a rate of 1 page fault per 1000 references introduced a 250 slowdown. If the SSD offers a time of only 80 µs, what is the slowdown in performance caused by 1 pf per 1000 references (you are not concerned with dirty vs. clean pages). What is the maximum rate of page faults you can accept if you want no more than a 5% slowdown in execution using virtual memory? Know your metric prefixes and symbols for time: s for seconds, ms for milliseconds, µs for microseconds, ns for nanoseconds.

Consider a demand-paging system with a paging disk that has an average access and transfer time of 25 milliseconds. Addresses are translated through a page table in main memory, with an access time of 1 microsecond per memory access. Thus, each memory reference through the page table takes two accesses. To improve this time, we have added an associative memory that reduces access time to one memory reference if the page-table entry is in the associative memory. Assume that 75 percent of the accesses are in the associative memory and that, of those remaining, 10 percent (or 2.5 percent of the total) cause page faults. What is the effective memory access time?
