Answer:
b. All rows in the employees table will be deleted if there are no constraints on the table.
Explanation:
This is a MySql command.
DELETE FROM table_name [WHERE Clause]
If the where clause is not estabilished, as it happens in this example, the entire table will be deleted. The where clause is the constraint, that is, whichever row you want to delete.
The correct answer is:
b. All rows in the employees table will be deleted if there are no constraints on the table.

You need to transfer data from one laptop to another and would like to use an Ethernet cable. You do not have a hub or a switch. Which type of cable should you use?
Answer:
The correct answer to the following question will be Crossover.
Explanation:
Crossover: The cable which is used to connect the same type of two Ethernet devices directly, known as Crossover cable also known as crossed cable. The temporary host-to-host networking can be created with the help of these types of crossed cables.
To connect the old router to the switch of a network, a normal cable will provide a link from the functioning.The crossover cable will be the most suitable cable for transferring the data from one device to another device, such as a laptop.So, Crossover is the right answer.
P3. In Section 4.2 , we noted that the maximum queuing delay is (n–1)D if the switching fabric is n times faster than the input line rates. Suppose that all packets are of the same length, n packets arrive at the same time to the n input ports, and all n packets want to be forwarded to different output ports. What is the maximum delay for a packet for the (a) memory, (b) bus, and (c) crossbar switching fabrics?

Physical access, security bypass, and eavesdropping are examples of how access controls can be ________.
Answer: Compromised
Explanation:
Access control is the controlling and management unit for handling the access of any user on a particular system. It implements a selective restriction on the users to access the function of computing system.
Authorized and permitted user are allowed to access the services and unauthorized party is not allowed for accessing the resources of the system. Permissible user can perform any task and consume service device.Compromising in access control depicts about intruding and spying of unauthorized user in devices that is eavesdropping. Security bypass is fault that lets the access to access system by another route.Thus, flaw in access control occurs then security of controlling and managing the system will be at risk as hacker and attacker can get access to perform function.Final answer:
Physical access, security bypass, and eavesdropping can compromise access controls that protect information within an organization. Implementing strong access control policies helps prevent unauthorized access and data breaches.
Explanation:
Physical access, security bypass, and eavesdropping are examples of how access controls can be compromised.
Access control mechanisms are critical for protecting the confidentiality, integrity, and availability of information. When these controls fail or are bypassed, it can lead to unauthorized access and potentially to the leakage or corruption of sensitive data. Physical access refers to situations where an unauthorized individual gains direct access to hardware or systems. Security bypass occurs when normal security procedures are avoided or circumvented, often due to system or human vulnerabilities. Eavesdropping is the act of secretly listening to private conversations or monitoring transmissions, which can be a form of information theft.
Organizations must implement strong access control policies and measures, including physical security, authentication protocols, and encryption, to reduce the risk of these types of compromises and to safeguard their information assets effectively.
Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text.
Final answer:
To write a program that takes in a line of text as input and outputs that line of text in reverse, you can use a loop to iterate through each character in the input string and concatenate them to a new string. The program can repeat until the user enters "Quit", "quit", or "q" for the line of text.
Explanation:
To write a program that takes in a line of text as input and outputs that line of text in reverse, you can use a loop to iterate through each character in the input string. Starting from the last character and moving backwards, you can concatenate each character to a new string. Here is an example program in Python:
line = input("Enter a line of text:")
reverse_line = ""
while line.lower() not in ["quit", "q"]:
for i in range(len(line)-1, -1, -1):
reverse_line += line[i]
print(reverse_line)
line = input("Enter a line of text:")
reverse_line = ""
Write a function that takes in a nonnegative integer and sums its digits. (Using floor division and modulo might be helpful here!)def sum_digits(n):"""Sum all the digits of n.>>> sum_digits(10) # 1 + 0 = 11>>> sum_digits(4224) # 4 + 2 + 2 + 4 = 1212>>> sum_digits(1234567890)45 """
Answer:
def sum_digits(n):
sum=0
while n>0:
num=n%10 #will store digits of number
sum+=num #sums the digits
n=int(n/10)
return sum #sum of digits is returned
Explanation:
In the above method , n is the number whose digit sum is to be returned. Sum is the variable which will store the sum of digits. Then a while loop will be executed until n is greater than 0 then num will store the individual digits of number and those digits will be added in sum variable. After that, n will be divided by 10. As we want only int variable we will typecast it into int.
Write a program that takes two numbers from the Java console representing, respectively, an investment and an interest rate (you will expect the user to enter a number such as .065 for the interest rate, representing a 6.5% interest rate). Your program should calculate and output (in $ notation) the future value of the investment in 5, 10, and 20 years using the following formula:
future value = investment * (1 + interest rate)^year
We will assume that the interest rate is an annual rate and is compounded annually.
Answer:
in this case you have to use a For cycle
Explanation:
This is the entire code for this program
Step 1: We declare two variables investment and interest with double, and we take the numbers with the console.
We ask with console the two numbers
We show the two number in console
Step 2: We create two new double variable: Value and cont5
We save the formula in the variable Value
We create 3 For cycle
the first one for 5 years
the second one for 10 years
the third one for 20 years
package javaapplication6;
import java.util.*;
public class JavaApplication6 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
double investment;
double interest;
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the investment");
investment = keyboard.nextDouble();
System.out.println("Enter the interest" );
interest = keyboard.nextDouble();
System.out.println("With an investment of $"+investment);
System.out.println("an interest rate of "+interest+"% compounded annually:");
double Value = investment * (1+interest);
double cont5 = Value;
//int Value = getValue(investment,interest,5);
for(int year = 1; year <= 4; year++){
cont5 = cont5 * Value;
}
System.out.println("In 5 years the value is : "+"$"+cont5);
double cont10 = Value;
//Value = getValue(investment,interest,10);
for(int year = 1; year <= 9; year++){
cont10 = cont10 * Value;
}
System.out.println("In 10 years the value is : "+"$"+cont10);
double cont20 = Value;
//Value = getValue(investment,interest,20);
for(int year = 1; year <= 19; year++){
cont20 = cont20 * Value;
}
System.out.println("In 20 years the value is : "+"$"+cont20);
}
}
Based on a customer's requirements, the CPQ Admin has created multiple configuration attributes and assigned them to a single feature. Which configuration is valid for displaying the attributes?Choose one answerA. Above or below all product options in the feature.B. Above or below the feature in the bundle.C. Above or below all features in the bundle.D. Above all product options in the feature."
Answer:
Option A is the correct option.
Explanation:
The following option is correct because the following configuration is used to show the attributes which assigned in the individual feature by the CPQ Admin. So, the following configuration is the valid configuration that fulfills the necessity of the customer's.
Option B, C, and D is not the valid configuration which based on the necessity of the customer's.
Describe precisely what the routers can send back to make prohibited outgoing TCP connections fail quickly. (Assume they cannot make any changes to the TCP implementation on clients.)
Answer:
See the explanation
Explanation:
1. The router can send back an ICMP error code indicating what happened in this case.
2. If you send back an ICMP error code, the user's connection attempt will fail immediately, otherwise it will time out which will take several minutes.
There are two types of ICMP codes they are destination unreachabl and destination administratively unreachable:
- The first pair of ICMP error codes(destination unreachable)might return, host unreachable and network unreachable. It is designed to indicate serious network problems.
- The second set of ICMP error codes the (destination administratively unreachable)might return, host administratively unreachable and network administratively unreachable.It is added to the official list of ICMP message types later, specifically to return when they dropped a packet.
If your router returns an ICMP error code for every packet that violates your filtering policy you are also giving an attacker a way to probe your filtering system.
If your router offers enough flexibility, it might make sense to configure it to return ICMP error codes to internal systems (which would like to know immediately that something is going to fail, rather than wait for a timeout) but not to external systems.
Hope this helps!

Given below is information about a network.
Choose one of the following three options:
A. the network is definitely a tree;
B. the network is definitely not a tree;
C. the network may or may not be a tree (more information is needed).
Accompany your answer with a brief explanation for your choice. The network has 11 vertices and 11 edges.
Answer:
Option (B) is the correct answer.
Explanation:
The network is used to share the information between two or more persons or systems in a connected pair. It has vertices and edges on which vertices mean the points which participate to communicate and edges are used for the medium by which communication is done.
The network can make the shape of a tree or not. If it follows the property of a tree we can say that it is a tree otherwise it can not be called a tree.
Here in the question, it is a given that there are 11 vertices and 11 edges.
But from the tree property if there are n vertices and n-1 edges then any circuit is called a tree, But this circuit has n edges and n vertices that's why it is not a tree. Hence option b is the correct answer.
While other is not valid because-
Option "a" suggests that this circuit is a tree that is not correct.Option b suggests that this circuit may or may not a tree but it is proved that this circuit is not a tree.Consider the following 3 programs:
1
//contents of file foo.c:
static int a = 5;
int main() {
f();
return 0;
}
//contents of file bar.c:
static int a = 10;
void f() {
printf("%d\n", a);
}
2
//contents of file foo.c:
int a = 5; int main() {
f();
return 0;
}
//contents of file bar.c:
void f() { int a = 10;
printf("%d\n", a);
}
3
//contents of file foo.c:
int a = 5;
int main() {
f(); return 0;
}
//contents of file bar.c:
int a;
void main() {
printf("%d\n", a);
}
If the command "gcc foo.c bar.c" is executed, which of the above programs result in a linker error?
Answer:
If the following programs are executed then Program 2 results "linker error"
Explanation:
Because In program 1, which is in the C Programming Language they declare the integer data type variable "a" as static in both files, so the scope of the static member is in the file or method then, the output of the following Program 1 is 10.
In the Program 2, which is in the C Programming Language they declare the integer data type variable in both files with initialization of 5 and 10, so when they execute the following Program 2 then, it occurs an "linker error" because the following program cannot find the value of the integer variable a.
In the Program 3, which is in the C Programming Language they declare the integer data type variable in both files but they initialize in the file "foo.c" is 5 and not initialize in the file "bar.c", so when they execute the following Program 3 then, its output is 5.

Which of the following function declarations correctly expect an array as the first argument?
Question 1 options:
void f1(int array, int size);
void f1(int& array, int size);
void f1(int array[100], int size);
void f1(float array[], int size);
All of the above
C and D
A and B
Answer:
Only
Option: void f1(float array[], int size);
is valid.
Explanation:
To pass an array as argument in a function, the syntax should be as follows:
functionName (type arrayName[ ] )
We can't place the size of the array inside the array bracket (arrayName[100]) as this will give a syntax error. The empty bracket [] is required to tell the program that the value that passed as the argument is an array and differentiate it from other type of value.
