Answer:

I. You should enter interface configuration mode.

II. Configure the IP address and subnet mask.

Explanation:

A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Some examples of network nodes are modem, hubs, computer, switches, phone and printers.

In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.

In Cisco devices, there are five (5) main types of command modes;

1. Sub-interface configuration mode.

2. Interface configuration mode.

3. Line configuration mode.

4. Router configuration method.

5. Global configuration mode.

Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.

In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;

I. You should enter interface configuration mode using the "configure terminal" command.

II. Configure the IP address and subnet mask.

See an example below;

"Router(config-if)# IP address 192.168.1.2 255.255.255.0"

Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum

NemiM [27]

Answer:

The answer to this question as follows :

Structure definition:

struct Server //define structure server.

{

string manufacturer;

//define string variable.

string model, serialnum; //define string variable.

int year;

//define integer variable.

double clockSpeed;

//define double variable.

int cores; //define integer variable.

int ram;

//define integer variable.

int storage;

//define integer variable.

};

Explanation:

Structure is a collection of heterogeneous(different type) elements. It is a user-define datatype which is available on the C/C++ programming language. To define any structure we use the struct keyword. The syntax of defining structure can be given as:

Syntax:

struct structure name

{

//define variables

//statements and code.

};

struct structure name

{

//define variables

//statements and code.

}create structure variable;

In the above structure code, we define a structure that is "Server". In this structure, we define different types of variables that is " manufacturer, model, serialnum, year, clockSpeed, cores, ram, and storage". In this structure variable manufacturer, model and serialnum datatype are a string and clockSpeed datatype is double and variable year, cores, ram, and storage data type is an integer.

Lisa manages incident response for a bank. The bank has a website that’s been attacked. The attacker utilized the login screen,

kari74 [83]

Answer:

The answer is C) SQL Injection

Explanation:

Cross-Site Scripting (XSS) attacks are a type attacks that occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user.

Cross-Site Request Forgery (CSRF) is a type of attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request.

SQL Injection is a type of cyber security attack where an attacker inputs a malicious input into an SQL statement., and the SQL server reads it as programming code.

Address Resolution Protocol poisoning (ARP poisoning) is a form of attack in which an attacker changes the Media Access Control (MAC) address and attacks an Ethernet LAN by changing the target computer's ARP cache with a forged ARP request and reply packets.

From the above brief definition; it is seen that the answer is C) SQL Injection.

Subtract (100000)2 from (111)2 using 1s and 2s complement method of subtraction

GenaCL600 [577]

Answer:

-11001

Explanation:

The following steps are performed in order to perform subtraction of the given binary numbers:

Step 1:

Find 2’s complement of the subtrahend. The subtrahend here is 100000

100000

First take 1's complement of 100000

1's complement is taken by inverting 100000

1's complement of 100000 = 011111

Now takes 2's complement by adding 1 to the result of 1's complement:

011111 + 1 = 100000

2's complement of 100000 = 100000

Step 2:

Add the 2's complement of the subtrahend to the minuend.

The number of bits in the minuend is less than that of subtrahend. Make the number of bits in the minuend equal to that of subtrahend by placing 0s in before minuend. So the minuend 111 becomes:

000111

Now add the 2's complement of 100000 to 000111

0 0 0 1 1 1

1 0 0 1 1 1

The result of the addition is :

1 0 0 1 1 1

Step 3:

Since there is no carry over the next step is to take 2's complement of the sum and place negative sign with the result as the result is negative.

sum = 1 0 0 1 1 1

2's complement of sum:

First take 1's complement of 1 0 0 1 1 1

1's complement is taken by inverting 1 0 0 1 1 1

1's complement of 1 0 0 1 1 1 = 0 1 1 0 0 0

Now takes 2's complement by adding 1 to the result of 1's complement:

0 1 1 0 0 0 + 1 = 0 1 1 0 0 1

Now place the minus sign with the result of 2's complement:

- 0 1 1 0 0 1

Hence the subtraction of two binary numbers (100000)₂ and (111)₂ is

(-011001)₂

This can also be written as:

(-11001)₂
