What can you conclude?
Answer:
There are multiple critical paths
Explanation:
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.
The essential technique for using CPM is to construct a model of the project that includes the following:
A list of all activities required to complete the project (typically categorized within a work breakdown structure), The time (duration) that each activity will take to complete, The dependencies between the activities and, Logical end points such as milestones or deliverable items.
Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer).
considering the above function of the cpm analysis because you have multiple path, there is tendency that more than path through the project network will have zero slack values.
A CPM analysis showing multiple pathways with zero slack values indicates there are several critical paths in the project, requiring careful management due to lack of buffer time.
If you've performed a CPM analysis (Critical Path Method) and found that more than one path through the project network has zero slack values, you can conclude that there are multiple critical paths. Having zero slack means that any delay in activities on these paths will delay the entire project. Therefore, these paths must be managed carefully as they have no buffer time and are equally critical to the project's timely completion.
What will the following segment of code output? Assume the user enters a grade of 90 from the keyboard. cout << "Enter a test score: "; cin >> test_score;
Complete Question:
What will the following segment of code output?
Assume the user enters a grade of 90 from the keyboard.
cout << "Enter a test score: ";
cin >> test_score;
if (test_score < 60);
cout << "You failed the test!" << endl;
if (test_score > 60)
cout << "You passed the test!" << endl;
else
cout << "You need to study for the next test!";
Answer:
You failed the test!
You passed the test!
Explanation:
With the assumption that test_score has been declared as an int variable
The output of: You failed the test! You passed the test! May be unexpected since the test_score is greater than 90 so it looks like the code has a logical error somewhere.
This error is as a result of putting a semi colon at then end of the first if statement if (test_score < 60);
An if statement does not end a thought as such there should'nt be a semi colon ending it. Take the semi-colon out and the program will give the expected output of You passed the test! since test_score of 90 is greater than 60
Your company has decided it wants to build a file server and store data that can be shared by coworkers. You were asked to research the type of storage that should be used on the server. Your boss said that he would like to implement RAID on the computer and wants your opinion on the best RAID type for the company. He informed you that the company will need at least 500 TB of storage. He also wants to make sure that if a drive fails, the data can be recovered. In addition, he told you to keep the cost down as much as possible. What will you recommend to your boss?
Answer:
RAID 5
Explanation:
One of the most common and best RAID configurations is the RAID 5. It is ideal for application and file servers with a restricted number of drives. RAID 5 is Considered as a good all-around RAID system in that it combines the better elements of efficiency and performance among the different RAID configurations.
Raid 5 is known to be fast, and reliable . It also offers cheap data redundancy and fault tolerance. Writes tend to be slower, due to the parity data calculation, but data can be accessed and read even when a failed drive is being rebuilt.
In a case of drive failure ,RAID 5 system can read the information contained on the other drives and recreate that data, accommodating a single drive failure.
In conclusion, the RAID 5 configuration is Cost Effective and has ability to recover from failures, thus it will be best option to be recommended tomy boss.
Final answer:
RAID 6 is recommended based on the need for at least 500 TB of storage, data recoverability from drive failures, and cost-effectiveness. It provides better data protection than RAID 5 and is more cost-effective than RAID 10, while maintaining the redundancy required for safe storage.
Explanation:
Considering the requirements of having at least 500 TB of storage, the necessity for data recovery in case of a drive failure, and the need to manage costs effectively, the RAID 6 configuration is recommended. RAID 6 provides fault tolerance by allowing up to two disk failures without data loss, which would give your company the redundancy needed to safeguard the stored data. While RAID 5 also provides fault tolerance, it only allows for a single drive failure, which might not provide enough protection for such a large data set. RAID 6, however, uses two parity blocks rather than one, giving it higher reliability.
It would require a minimum of 4 drives, and because of the dual parity, it would slightly reduce the total storage size available. However, this is a cost-effective solution compared to more expensive options like RAID 10, which offers great performance and redundancy but would require double the number of drives for the same usable storage space. When selecting drives for the RAID array, using enterprise-level hard drives is recommended as they are made for the rigors of continuous operation, which can extend the reliability and lifespan of your storage system.
