Using a referential integrity rule will prevent you from adding data to table Y that cannot be linked to data in table X. In order to maintain referential integrity, any records that are linked to a removed record from table X must also be deleted. A database is considered to be in referential integrity when all values for all foreign keys are valid. Foreign keys are a column or set of columns in a table that must contain values that correspond to at least one of the main key or unique key values of a row in its parent table.

To scan from a fake IPS, what Nmap command should be used?Nmap offers a -D option. It is known as a decoy scan. When you designate one or more hosts as decoys, the -D option makes it appear to the remote host that they are also scanning the target network. As a result, even if their IDS may detect five to ten port scans from distinct IP addresses, they won't know which IP was actually scanning their ports and which was only a ruse.

a company wants to transmit data over the telephone, but is concerned that its phones could be tapped. all of the data are transmitted as four-digit integers. the company has asked you to write a program that encrypts the data so that it can be transmitted more securely. your program should read a four-digit integer and encrypt it as follows: replace each digit by (the sum of that digit plus 7) modulus 10. then, swap the first digit with the third, swap the second digit with the fourth and print the encrypted integer. your main duty for this assignment is creating an encrypt class which includes encrypt.h and encrypt.cpp. after finishing the task you can use cisp400v10a2.cpp to test the encrypt class. the following is the encrypt class specification. 1. the encrypt class has an integer private data member 8 element array named digits. the first four elements (0 ~ 3) are to store the original 4 digits integer and the next four (4 ~ 7) are to store the encrypted data. 2. encrypt class has several public member functions a. an encrypt constructor takes an integer of any digits and stores the last four digits. it encrypts the last four digits, stores the encrypted information, displays a call to the constructor information, and shows the original information and encrypted information. if the inputted number is less than or equal to 0 the integer is set to 9436. b. a displayoriginaldata function does not accept and return any data. it displays the first four elements of the private data member. page 3 of 6 cisp400v10a2 3 c. a storedata function takes an integer and does not return anything. it stores the last four digits of the passed in integer to the first 4 elements of the private data member, encrypts the data and store them in the last 4 elements of the private data member. d. a displayencrypteddata function does not accept and return any data. it displays the last four elements of the private data member.
The Encrypt class is a class that is used to encrypt data that is transmitted over the telephone. The class has an integer private data member which is an 8-element array named digits.
What is encrypt data?Encrypting data is a process of transforming plain text data into a form that is unreadable to anyone except the intended recipient. It is used to protect the confidentiality of data and to ensure that it is only available to those who are authorized to access it.
The first four elements (0-3) are used to store the original four-digit integer, and the next four (4-7) are used to store the encrypted data.

) suppose that server a is sending client b packets of size 2000 bits through router r. also assume that the link is 1gb/s and the rate at which packets arrive at router r is 450,000 packets per second. what is the average queueing delay at this link?
Answer:
Explanation:
L/R=2 microsecond or 0.000002 s, traffic intensity I is 0.000002 * 450,000 = 0.9
Queuing delay = I *L/R*(1-I)= 0.000002*0.9*0.1=0.18 microsecond
The average queueing delay at the given link is 0.9 milliseconds.
Explanation:Calculating the Average Queueing Delay:
The average queueing delay at a link can be calculated using the formula:
Average Queueing Delay = (Packet Size * Packet Arrival Rate) / Link Capacity
In this case, the packet size is 2000 bits, the packet arrival rate is 450,000 packets per second, and the link capacity is 1 Gbps (1 billion bits per second). Plugging in these values into the formula, we get:
Average Queueing Delay = (2000 * 450,000) / 1,000,000,000

Address Resolution Protocol (ARP) is a protocol used to map an Internet Protocol (IP) address to a physical machine address, such as a Media Access Control (MAC) address. ARP is used to discover the MAC address of any host on a local area network (LAN) so that data can be sent from one host to another. The IP address is used to identify the host, while the MAC address is used to identify the physical port of the host. ARP operates by broadcasting a request to all hosts on the LAN, asking the host with the specific IP address to identify itself. The host with the specified IP address then responds with its MAC address. This is how ARP resolves the IP address to the MAC address.
