firewall rules evaluate from top to bottom. the rule creators intended to block access to a website hosted at 10.15.1.2, except from hosts located on the 10.20.0.0/16 subnet. however, users on that subnet report that they cannot access the site. what is wrong?
Answers
The reason users cannot access the site is: The rules are misordered.
About Firewall:
A firewall is a type of network security device used in computing that keeps track of and regulates incoming and outgoing network traffic according to pre-set security criteria. A firewall often creates a wall between a reliable network and an unreliable network, like the Internet.
Firewall Rules:
The access control method employed by firewalls to protect your network from malicious apps and illegal access is called the firewall rules. Your firewall's acceptance and denial of different types of traffic are controlled by firewall rules. The firewall access policy is a set of firewall rules. Each network packet's control information is examined, and based on the standards you specify, they are either blocked or allowed. Each package is first assessed from top to bottom, and its constituent parts are contrasted with those of the policy regulations. Then, all of the steps specified in the stated parameters of the first matching rule's configured action are carried out.
Every firewall rule matches packet characteristics against a collection of shared rule elements. The packet's source address (Source), destination address (Destination), protocol and port numbers (Service), the interface it travels across (Interface), the direction it is traveling in (Direction), and the time of arrival are among the rule components that are displayed as fields (Time).
User can fix this mistake by reversing the order of rules 2 and 3. Any communication from the network 10.20.0.0/16 also matches rule 2, which blocks it, thus rule 3, which allows access, will never be activated.

what is the maximum number of devices that you can connect to a single usb 2.x controller?
Answers
The maximum number of devices that you can connect to a single USB 2.x controller is 127.
USB (Universal Serial Bus) 2.x is a widely used interface for connecting peripherals to a computer. It supports the concept of a USB hub, which allows multiple devices to be connected to a single USB port. Each USB hub consumes one device slot, and a USB controller can support up to 127 devices, including the hub itself. This means you can connect up to 127 devices, including hubs and peripherals, to a single USB 2.x controller, providing sufficient power is available to support all the connected devices.

Why does a wireless router frequently receive a DHCP address from an ISP in a SOHO context for convenience in managing IP addresses?The ISP commonly uses DHCP to assign the IP address between the wireless router and ISP site. In this system, IP addresses are dynamically assigned to clients, making it simple to assign the assigned IP address to another client in the event that a dropped client.

Assume that x and y are boolean variables and have been properly initialized. !(x || y) || (x || y) The result of evaluating the expression above is best described as:
Answers
Answer:
The answer is "Always true "
Explanation:
Following are the program to this question:
#include <iostream>//header file
using namespace std;
int main()//main method
{
bool x=true;//defining bool variable x and assign value
bool y=false;//defining bool variable y and assign value
if(!(x || y) || (x || y))//use given condition with if block
{
cout<<"True";//print true message
}
else//defining else block
{
cout<<"false";//print false message
}
return 0;
}
In the above code two bool variable is declared, that hold ture and false, and used in the given expression with the condition statement, that checks the given value. In the code the logical gate OR gate that always print the true value.
Which code segment results in "true" being returned if a number is even? Replace "MISSING CONDITION" with the correct code segment.
function isEven(num){
if(MISSING CONDITION){
return true;
} else {
return false;
}
}
A. num % 2 == 0;
B. num % 0 == 2;
C. num % 1 == 0;
D. num % 1 == 2;
Answers
Answer:
The answer is "Choice A".
Explanation:
In this code, a method "isEven" is declared that accepts the "num" variable in its parameter, and inside the method and if block is declared that checks the even number condition if it is true it will return a value that is "true" otherwise it will go to else block that will return "false" value, that's why other choices are wrong.
The correct code segment that tests if a number is even is num % 2 == 0
When a number is divided by 2, and the remainder after the division is 0, then it means that the number is an even number.
Assume the variable that represents the number is num
The condition that tests for even number would be num % 2 == 0
Hence, the correct code segment that tests if a number is even is (a) num % 2 == 0

Every hour during the workday, your employee checks a constantly-updated spreadsheet that tracks how many items are sold; each hour of the workday, the total number of items for a column are entered as a negative number. At the end of each workday, the employee calculates the total remaining by adding the starting total stock (in row B) and the 12 rows representing sales—this is entered into a separate spreadsheet, the new total goes into row B, and the remaining data is cleared.
You want to set up a spreadsheet that, during that hourly check, lets the employee quickly look at a single cell for each of the five columns representing items you sell and see whether your remaining stock, after your deliveries for the sales that day, would be below 50 units, so you know whether to order more.

Using the Caesar cipher, "HELLO" is encrypted to "OLSSV" by applying a shift of 7. The number 7 is considered the __________
Answers
Answer:
The offset
Explanation:
In the question, we understand that the original text is HELLO and the encrypted text is OLSSV.
It should be noted that O replaced H, L replaced E, S replaced L and V replacement O.
This is made possible by a term refered to as offset.
The offset is used to determine the character that will replace another when it is encrypted.
7 characters after H is O; this is same for every other characters in the text.
The example given represents a simple shift cipher encryption with each letter in the original text shifted by a fixed value. Hence, the shift value of 7 used in the cipher given is called the key.
Each alphabet on the original text, HELLO is shifted by the key 7 to produce :
H + 7 alphabets gives OE + 7 alphabets gives LL + 7 alphabets gives SL + 7 alphabets gives SO + 7 alphabets gives VThis produces the encryption OLSSV, hence, with the shift of 7 known the encryption letters are each reversed by 7 to obtain the actual phrase 'HELLO'.

what are the main objects that make up an access database?
Answers
An Access database is made up of several objects, including tables, queries, forms, reports, macros, and modules. Each of these objects serves a specific purpose in managing and manipulating data within the database. Tables are the backbone of an Access database, providing the structure for storing data.
They consist of columns (fields) and rows (records) that organize information in a logical way. Queries are used to extract specific data from tables based on certain criteria. They can be designed to perform complex calculations, search for patterns, or join multiple tables together. Forms are used to enter and view data in a more user-friendly way than tables. They provide a graphical interface that allows users to input and edit data, and can be customized to match specific business needs. Reports are used to present data in a professional format, often including charts and graphs for visual representation.
Macros are automated commands that perform a series of actions, such as opening forms or running queries. They can simplify repetitive tasks and improve efficiency. Modules are collections of custom programming code that can be used to add functionality to the database, such as creating custom reports or interacting with other programs. In summary, the main objects that make up an Access database are tables, queries, forms, reports, macros, and modules. Each of these objects plays an important role in managing and manipulating data within the database, and can be customized to meet specific business needs.
