Answers
Answer:
1. The solution to question 1 is as follows;
srand(seedVal);
cout<<rand()%10<<endl;
cout<<rand()%10<<endl;
2. The solution to question 2 is as follows
cout<<100+rand()%50 <<endl;
cout<<100+rand()%50 <<endl;
Explanation:
The general syntax to generate random number between interval is
Random Number = Lower Limit + rand() % (Upper Limit - Lower Limit + 1)
In 1;
The solution starts by calling srand(seedVal);
The next two statements is explained as follows
To print two random integers between intervals of 0 and 9 using rand()"
Here, the lower limit = 0
the upper limit = 9
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 0 + rand() % (9 - 0 + 1)
Random Number = 0 + rand() % (10)
Random Number = rand() % (10)
So, the instruction to generate the two random variables is rand() % (10)
2.
Similar to 1 above
To print two random integers between intervals of 100 and 149 using rand()"
Here, the lower limit = 100
upper limit = 149
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 100 + rand() % (149 - 100 + 1)
Random Number = 100 + rand() % (50)
So, the instruction to generate the two random variables is 100 + rand() % (50)
Write a program that lets the Michigan Popcorn Company keep track of their sales for seven different types of popcorn they produce: plain, butter, caramel, cheese, chocolate, turtle and zebra. It should use two parallel seven-element arrays: an array of strings that holds the seven popcorn names and an array of integers that holds the number of bags of popcorn sold during the past month for each popcorn flavor. The names should be stored using an initialization list at the time the flavors array is created. The program should prompt the user to enter the number of bags sold for each flavor. Once the popcorn data has been entered, the program should produce a report for each popcorn type, total sales, and the names of the highest selling and lowest selling products.

c. Identify the encryption algorithm and attempt a brute force attack to get access to the file.
d. Disconnect the hard drive from power so the encryption key can be exposed on the next power up.
e. Try to copy the drive bit by bit so you can see the files in each directory.
Answers
Answer:
b. Try to convince the owner of the computer to give you to decryption key/password.
Explanation:
Encrypted hard drives have maximum security and high data protection. to access them you need to enter a password to unlock them.
The image filtering technique is a method that serves to selectively highlight information contained in an image, for which it does not work.
The encryption algorithm is a component used for the security of electronic data transport, not to access data on an encrypted hard drive.
The encryption key is used in encryption algorithms to transform a message and cannot be exposed by disconnecting the hard drive from its power source.
When implementing a physical database from a logical data model, you must consider database performance by allowing data in the database to be accessed more rapidly. In order to increase data availability, the DBA may break up data that are accessed together to be stored together. Which method will improve the performance of this structure when running queries? What are advantages and disadvantages of this method?
Answers
Answer:
A method used to improve the performance of structure when running queries is known as Partitioning indexes.
The advantages of partitioning indexes are, It enables data management operations for example, index creation and rebuilding, It increases query performance.
The disadvantages are, one cannot define the primary index of partitioned table to be unique unless the whole partitioning column set is part of the primary index definition.
Explanation:
Solution
Partitioning indexes are known as b -tress indexes that shows hon how to break up the index into separate or different partitions.
Partitioning is usually done to enhance the performance and increased availability. when data are spread over multiple partitions, one can be able to operate on one partition without affecting others. i.e to run utilities, or to take data offline.
Almost all DBMS products support partitioning, but in various ways. we must be sure to know the nuances of an individual a particular DBMS execution before partitioning.
The advantages of Partitioned indexes are as follows:
It enables data management operations for example, index creation and rebuilding
It increases performance of query
It can significantly the impact of schedule downtime for maintenance operations
Disadvantages:
The primary index of partitioned table cannot be described to be unique except if the whole partitioning column set is part of the primary index definition.

A laptop computer has two internal signals: An unplugged signal, which is '1' if the laptop's power supply is connected, and '0' otherwise. A low battery signal, which is '0' if the laptop's battery has reached an almost empty state, and '1' otherwise. Suppose the laptop's power control system accepts a single hibernate signal which determines if the laptop should change its current operating state and shut down. If the laptop should shut down when the battery is low and its charger is unplugged, which gate could be used to produce the hibernate signal?
Answers
Answer:
The correct usage is a NOR gate which is indicated in the explanation.
Explanation:
The truth table for the given two signals, namely
p=unplugged signal
q=low battery signal
can form a truth table of following form
Here p has 2 states
1 if the power supply is connected
0 otherwise
Similarly q has 2 states
0 if the battery has reached almost zero state
1 otherwise
As the condition for the Hibernate Signal is given as to only activate when the battery is low and the power supply is not connected. This indicate that the value of Hibernate signal should be 1 when both p and q are 0.
Using this condition, the truth table is formed as
unplugged signal | low battery signal | Hibernate Signal
0 | 0 | 1
0 | 1 | 0
1 | 0 | 0
1 | 1 | 0
Now the truth table of NOR is given as
a | b | a or b | ~(a or b)
0 | 0 | 0 | 1
0 | 1 | 1 | 0
1 | 0 | 1 | 0
1 | 1 | 1 | 0
This indicates that the both truth tables are same thus the NOR gate is to be used for this purpose.

The following if statement uses an overloaded > operator to determine whether the price of a Car object is more than $5000. Car is a struct and myCar is an object of Car. Each Cor object has two variables: id (int) and price (float). As you can see in the following code, the ID of myCar is 12345 and the price is $6,000. Car myCar - [12345, 6000.); float price - 5000; if (myCar > price) cout << "My car price is more than $5,000/n": Which one of the following function prototypes is correct syntax to overload the > operator based on the if statement above. void operator> float price: O bool operator>(Car & car, float price): bool operator (float amt): bool operator> Car & your Car): None of the above
Answers
Answer:
The correct syntax to overload is bool operator (float amt): so, the third statement is right.
Explanation:
Solution
From the given question we have to find which statements is correct for the following function prototype.
Now,
Since the price of a Car object is above $5000, the car here is considered a struct and myCar is an object of Car
Both Car object consists of two variables which are id (int) and price (float)
Thus, from the given example the corresponding code says that the ID of myCar is represented as follows:
myCar - [12345, 6000);
The float price = 5000
Then,
cout << "My car price is more than $5,000/n"
Therefore the following statement bool operator (float amt): is the right syntax to overload.

What would the following statements display?

a) 20 30
b) 40 50
c) 10 20
d) 30 40
Answers
Answer:
A. 20 30
Explanation:
Given
Linked list: 10, 20, 30, 40, 50, 60
Required
The output of the following code segment
pCur = head->next;
cout << pCur->data << " ";
cout << pCur->next->data << endl;
A linked list operates by the use of nodes which begins from the head to the next node, to the next, till it reaches the last;
The first line of the code segment; "pCur = head->next; " shifts the node from the head to the next node
The head node is the node at index 0 and that is 10;
This means that the focus has been shifted to the next at index 1 and that is 20;
So, pCur = 20
The next line of the code segment; cout << pCur->data << " "; prints pCur and a blank space
i.e. "20 " [Take note of the blank space after 20]
The last line "cout << pCur->next->data << endl; " contains two instructions which are
1. pCur = next->data;
2. cout<<pCur->data;
(1) shifts focus to the next node after 20 ; This gives pCur = 30
(2) prints the value of pCur
Hence, the output of the code segment is 20 30

Brute force is technique that is used for cracking password
In this case the system uses only three characters(0-9). By applying Brute force attack in "hit and try" manner we easily crack the password.
Explanation:
Solution
There are a wide variety of password cracking mechanisms.Brute force is one of the popular password cracking technique.Brute force attack is generally used to crack small passwords.
In the given example the system uses only three characters(0-9).By using Brute force attack in "hit and try" manner we easily crack the password.There are only 10 possible passwords for this type of system.Because we can arrange 0-9 only in 10 ways.But for Systems with long passwords it is difficult to find it in hit and try manner.But instead of having plain password each password have a random salt value.
In a system of 32 bit salt value there are 2^32 different key values.
By increasing the salt value from 32 bits to 64 bits there are 2^64 different key values.It increases the time taken to crack a password for an attacker.so by changing salt value from 32 to 64 bits will make it more harder for the adversary's attack to be successful.

In which contingency plan testing strategy do individuals follow each and every IR/DR/BC procedure, including the interruption of service, restoration of data from backups, and notification of appropriate individuals?
a. Full-interruption
b. Desk check
c. Simulation
d. Structured walk-through
Answers
Answer:Full-interruption--A
Explanation: The Full-interruption is one of the major steps for a Disaster Recovery Plan, DRP which ensures businesses are not disrupted by saving valuable resources during a disaster like a data breach from fire or flood.
Although expensive and very risky especially in its simulation of a disruption, this thorough plan ensures that when a disaster occurs, the operations are shut down at the primary site and are transferred to the recovery site allowing Individuals follow every procedure, ranging from the interruption of service to the restoration of data from backups, also with the notification of appropriate individuals.
TCPDump is used by Wireshark to capture packets while Wireshark own function is:
a. to provide a graphical user interface (GUI) and several capture filters.
b. to act as an intrusion prevention system (IPS) by stopping packets from a black-listed website or packets with payloads of viruses.
c. to defend the network against TCP SYN Flooding attacks by filtering out unnecessary TCP packets.
d. yet to be defined.

Answer:
a. to provide a graphical user interface (GUI) and several capture filters
Explanation:
TcPDump is a command line tool used to capture packets. TcPDump is used to filter packets after a capture has been done. To control network interfaces, TcPDump need to be assigned root privileges. Data is represented in form of text
Wireshark provide a graphical user interface (GUI) and several capture filters. It is a graphical tool used in packet capture analysis. Data is represented in wireshark as text in boxes.

Answer:
2910 to binary = 101101011110
2910 to hexadecimal = B5E
2910 to octal = 5536
E316 to binary = 1110001100010110
E316 to octal = 161426
E316 to decimal = 58134
5916 to binary = 101100100010110
5916 to decimal = 22806
5916 to octal = 54426
010010102 to decimal = 149
010010102 to octal = 225
010010102 to hexadecimal = 95
FOR 438 and 618, 8 is not a valid digit for octal..
Describe and list advantages and disadvantages of each of the following backup types:
full, differential, incremental, selective, CPD, and cloud.
Answers
Answer:
Full back up
It creates complete copy of the source of data. This feature made it to the best back up with good speed of recovery of the data and simplicity.However, because it is needed for backing up of a lot of data, it is time consuming process,Besides it also disturbs the routine application of the technologist infrastructure. In addition large capacity storage is needed for the storage of the large volume of back up with each new creation.
Incremental back up: back up work at high speed thus saves time, Little storage capacity is needed. This type of back up can be run as many time as wished.
However, the restoration of data takes time, due to the time spent for restoration of initial back up and the incremental.
Differential Back up has very fast back up operation, because it only requires two pieces of back up.This is however slower compare to the Incremental.
The selective back up enable selection of certain type of file or folders for back up.
it can only be used to back up folders only when important data are needed only.Thus the storage capacity is low.
CPD eliminates back up window and reduces the recovery point objective.However, it has issue of compatibility with the resources to back up.,it is also expensive because its solutions are disk based.
Cloud based is affordable and save cost,It is easier to access. it is efficient,it can be access remotely for convenience.
However, Internet sources and some bandwidth must be available for access., always depends on third party providers,There is also problems encountered when switching providers.
Explanation:
C++ Problem: In the bin packing problem, items of different weights (or sizes) must be packed into a finite number of bins each with the capacity C in a way that minimizes the number of bins used. The decision version of the bin packing problem (deciding if objects will fit into <= k bins) is NPcomplete. There is no known polynomial time algorithm to solve the optimization version of the bin packing problem. In this homework you will be examining three greedy approximation algorithms to solve the bin packing problem.
- First-Fit: Put each item as you come to it into the first (earliest opened) bin into which it fits. If there is no available bin then open a new bin.
- First-Fit-Decreasing: First sort the items in decreasing order by size, then use First-Fit on the resulting list.
- Best Fit: Place the items in the order in which they arrive. Place the next item into the bin which will leave the least room left over after the item is placed in the bin. If it does not fit in any bin, start a new bin.
Implement the algorithms in C++. Your program named bins.cpp should read in a text file named bin.txt with multiple test cases as explained below and output to the terminal the number of bins each algorithm calculated for each test case. Example bin.txt: The first line is the number of test cases, followed by the capacity of bins for that test case, the number of items and then the weight of each item. You can assume that the weight of an item does not exceed the capacity of a bin for that problem.
