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.
Which of the following statements about Java Class Libraries is false? Question 18 options: A) An advantage of using Java class libraries is saving the effort of designing, developing and testing new classes. B) Java class libraries are also known as Java APIs (Application Programming Interfaces). C) Java class libraries consist of classes that consist of methods that perform tasks. D) Java class libraries are not portable
Answer:
D) Java class libraries are not portable
Explanation:
The Java Class Library (JCL) is an array of enthusiastically loadable libraries that Java applications can identify and refer to at run time. Since the Java Platform is independent of any particular operating system, applications can’t depend on any of the platform-native libraries.
The library is a massive collection and works of prebuilt classes that is distributed through the Java SE platform.

Use two variables k and total to write a for loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus, your code should put 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 into total. Use no variables other than k and total.
Answer:
Following are the statement in the C++ Language
int total=0; // variable declaration
int k;// variable declaration
for(k=0;k<50;k++) // iterating the for loop
{
total=total+k*k;// perform operation and calculating square of 50 number
}
Explanation:
Following is the description of the statement
Declared a variable "total" and "k" of the "int" type initialized the total variable with the value 0. Iterating the for loop for calculating the squares of the first 50 counting numbers. So we will execute the loop less then 50 . In this loop, we counted the square of 50 number in the "total" variable.In a ____________________ attack, the attacker sends a large number of connection or information requests to disrupt a target from many locations at the same time.
DDoS - Distributed Denial of Service
Explanation:
In DDoS attack, the attack comes from various system to a particular one by making some internet traffic. This attack is initiated from various compromised devices, sometimes distributed globally through a botnet. It is different from other attacks such as (DoS) Denial of Service attacks, in which it utilizes an unique Internet-connected device ( single network connection) to stream a target with the malicious traffic. So in DDoS, multiple systems are involved in the attack and hence we can conclude that as the answer.A user calls to report that she is experiencing intermittent problems while accessing the wireless network form her laptop computer. While talking to her, you discover that she is trying to work form the break room two floors above the floor where she normally works.
Which of the following is the MOST likely cause of her connectivity problem?
• The user has not yet rebooted her laptop computer while at her new location.
• The user needs a new IP address because she is working on a different floor.
• The wireless network access point on the user's normal floor has failed.
• The user is out of the effective range of the wireless access point on her floor.
• The user has not yet logged off and back on to the network while at her new location.
Answer:
The user is out of the effective range of the wireless access point on her floor.
Explanation:
This user is obviously not close to the access point. As help desk, if a user ever calls to complain about slow speeds or intermittent connectivity while trying to access the network, the first question that you should ask them is how far out are they from the modem or the Access Point. The location between her and the access point might affect the performance of the wireless network. Since she is working from the break room that is two floors above the floor where she normally works, then this means that the walls and ceilings will act as an obstruction to the Wi-Fi signal. The number of Walls and other obstacles will obviously affect the range of the Wi-Fi and will limit the signal’s effectiveness. I will advise the user to go back to her initial working area or be within range to the access point.

The use of simulations has been limited by their ____ a. inability to incorporate situations that a trainee might encounter b. inability to be used on a desktop computer c. need for employees to travel to a central training location d. high development costs
Answer: d
High development costs.
Explanation: Simulation is an approximate imitation of a process or a system that represents it overtime.
In Computer simulation is said to be a process of mathematical modelling that is performed on a computer and is designed to predict the behaviour of or the outcome of a physical system. Computer simulations are now useful tools for the mathematical modeling of many natural systems like in computational physics, astrophysics, climatology, chemistry, biology and manufacturing and also human systems like in economics, psychology, social science, health care and engineering.
" Simulations can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions and also to do a wide range of other things", but its development cost is very high, Very expensive.
Answer:
D. High development costs
Explanation:
Simulations try to as much as possible imitate the functions or activities of a system or process. They cut across various disciplines such as education, technology, science, management and so on.
One common ground about simulations is that it accrues high development costs. This is due to its closeness to the real-world application. Each block of the real process has to be appropriately simulated to ensure that the same results are obtained.
If the destination file is closed when you make a change in the source file, you choose whether to update the link to display the current values when you open the destination file or continue to display the older values from the destination file.a) trueb) false
Answer:
True
Explanation:
When changes are made in the source file, even if the destination file is closed, you can either do any of these two; you choose whether to update the link to display the current values when you open the destination file or continue to display the older values from the destination file till the destination file is opened.
Any of the two you choose will not affect the changes already made at the source file becsuse the source file controls the activities in the destination file.
Hence, the statement as ascertained to be true.
In a real-world environment, changing granularity requirements might dictate changes in primary key selection, and those changes might ultimately require the use of ____________________ keys.
In a real-world environment, changing granularity requirements might dictate changes in primary key selection, and those changes might ultimately require the use of surrogate keys.
Explanation:
A surrogate key is a unique identity as an object or entity. It is used as an object in the database and as an entity in the modern world. Surrogate key is not a natural key hence it cannot be derived from application data.
Advantages of using surrogate key:

When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ______ in the purchased decision process.
Answer:
Hi you haven't provided the options to the question so I will just give the answer in my own words and you can check with the options.
Answer is ALTERNATIVES
When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ALTERNATIVES in the purchased decision process
Explanation:
Purchase decision process is the decision making process used by consumers regarding the market transactions before, during and after the purchase of a good or service.
There are five stages involved in purchase decision process which are: need recognition,
Information search, evaluation of alternatives, purchase decision and post purchase behavior.
Evaluation of alternatives: The information search reveals different products for the consumer to evaluate and understand which product would be appropriate, this can also be referred to as the consumer's alternatives.
Therefore, the answer that best suits the question is ALTERNATIVES. When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ALTERNATIVES in the purchased decision process
Answer:
They are my "Alternatives" in the purchase decision process
Explanation:
Before customers take the bold step of purchasing goods or paying for services, they usually pass through five stages. These five stages are:
1. The problem recognition stage.
2. The information search stage.
3. Evaluation of alternatives stage.
4. Purchase decision stage.
5. Post- purchase evaluation stage.
This then implies that before a product is finally purchased or before a service is paid for, the process of buying that product/service commences long before the actual acquisition of the service/product.
In the first stage, the consumer understands/recognizes that there is a problem or need that could be met by a product.
In the second stage, after recognition of the need that must be met by a product or service, the consumer then makes moves to search for further information regarding the possible products that could meet this need.
After the consumer has satisfactorily gathered enough information regarding the products that can possibly meet those needs, he/she then starts evaluating those products/service with regards to the belief in the company producing the products, the degree of importance, characteristics and abilities of the commodity, satisfaction, price etc, in order to choose wisely and correctly.
Therefore, if I consider price, sound quality etc when evaluating portable CD player, those things I consider are my alternatives in the purchase decision process.

Which of the following is not a component of the programming phase of facility construction? deciding what to build examining space, cost, and other criteria designing the facility with architects deciding what events will be held at the facility and addressing capacity and amenities issues deciding the number and location of food and beverage preparation and sales areas
The programming phase focuses on fundamental design and planning aspects of facility construction but does not typically include deciding which events will be held at the facility. It lays out foundational design elements like capacity and amenities, while event scheduling pertains to operational planning.
The component that is not a part of the programming phase in facility construction is 'deciding what events will be held at the facility'. Programming, as a part of the design process, focuses on gathering information about the project, such as site inventory, analysis, and understanding user needs, environmental conditions, and economic considerations. This phase includes activities like deciding what to build, examining space, cost and other criteria, and integrating findings into the design with architects. It specifically deals with the fundamental aspects of designing the facility, ensuring the design maintains a focus on elements like capacity and amenities to meet users' needs. However, decisions related to events pertain to operational planning, which is distinct from the initial construction programming.
Programming provides the critical foundation for later stages such as schematic design, design development, construction documentation, and construction administration. This early stage of planning helps lay out the essential frameworks and supports potential adaptability in design—not detailed operational planning such as event scheduling.
You are planning to add CSS to a web page that was written with HTML and has lists on the page. What new formatting option will you gain by including CSS?
Answer: Easily alter the color of all list to a different one.
Explanation: Cascading Style Sheet (CSS) is mainly used to style documents written in Markup language such as Hypertext Markup Language (HTML). Cascading Style Sheet is a robust due to the ease afforded to web designers in the alteration and modification of styles applied to documents written in Markup Language. It gives users or designers more control over the style of documents, it is easier and ultimately saves a lot of time.
In the scenario above, adding CSS allows the user to change or alter the style of the list, such as color much more easily.

Give a recursive implementation for the function: def is_sorted(lst, low, high) This function is given a list of numbers, lst, as well as two indices: low and high (low ≤ high), which indicate the range of the indices for the elements that should to be considered. When called, the function should determine if the elements that are placed at the low, low+1, …, high positions, are in an (ascending) sorted order. That is, it should return True if-and-only-if lst[low] ≤ lst[low+1] ≤ … ≤ lst[high] For example, if lst = [1, 3, 6, 8, 12, 15, 31], the call is_sorted(lst, 0, 6), will return True. Implementation requirements: Your function should run in worst case linear time. That is, if n is the size of the range low, low+1, …, high, calling is_sorted(lst, low, high) will run in �(�). Note: Write your implementation.
Answer:
# recursive method to find if list is in ascending order
def is_sorted(list, low, high):
if low >= high: # if reached end of list
return True
if list[low] > list[low+1]: # if item at low is greater than low+1
return False # return false
return True and is_sorted(list, low+1, high) # or return True and recursion call to low+1

the program is running, it can use the class to create as manyobjects of a specific type as needed. Each object that is created from aclass is called a(n) __ of the class
Answer: "An instance of a class"
Explanation:
When you create an object, you are creating an instance of a class, therefore "instantiating" a class.
You create an object from a class, thus you can say that a class provides the blueprint for objects.
When used in object-oriented programming, a class is a factory for creating objects and Such objects are called "instances" of the class.
