Answer:

For the above condition, and as mentioned none of the mode will work, and we need to make use of the JSON format. And we nee to use the JavaScript, and we don't need to mention the mode in JavaScript. Thus, this is nowadays used solution for this old problem that existed when we used to code using c++ and c.

Explanation:

You need to write over this text file, and you also need to read. Hence, you need to open the file with the three privileges, and the append will be required,and this way we can only move line by line. However, this is an old style. Now we save in text file in JSON format. The data collected  from Form is converted to JSON format and written in text file. And as required data can be read or written, and as required.  So if we use only JSON format, then we need not mention the mode, as its not required these days in new languages like JavaScript.

The Knowledge Consistency Checker (KCC) ensures the maximum number of hops between any two domain controllers does not exceed wh
Katarina [22]

Answer:

Three (3)

Explanation:

Explanation of the three basic terms here - Knowledge consistency checker, hops and domain controller - will give a clearer answer and explanation to the question as follows;

<em>Domain controller</em> : is a server controller that gives access or controls to users on computer networks by first responding to their authentication requests and verifying those users. In other words, a domain controller is a network security manager.

<em>Hop</em> : A hop is simply the passage of data packets from one network to another. As  a packet moves from its source to destination, it moves from router to router. The number of such routers that the packet passes through is called a hop.

<em>The Knowledge Consistency Checker (KCC)</em> :  It is the job of the KCC to ensure that these domain controllers participate in the replication promptly and orderly. Replication means copying data from one location to another (within a network or among networks). The KCC ensures that the maximum number of hops permitted is does not exceed 3. i.e no domain controller is more than 3 hops from any other domain controller within a network.

Note: Replication is of two types - intrasite (among all domain controllers within a site) and intersite (among all domain controllers in different sites), and the KCC can manage both type of replication. Also, by default, at every 15 minutes interval, a domain controller generates a replication topology (a logical map that dictates the domain controllers that will replicate with each other).

<em>Hope this helps!</em>

You are a network administrator for a large bagel manufacturer that has 32 bakeries located throughout the United States, United
Anni [7]

Answer:

See the components in explaination

Explanation:

In order to make it as IPv6, few key components should be supported, those components are given below:

The infrastructure must support the enhanced protocol StateLess Address Auto-Configuration (SLAAC).

Static addressing with DHCPv6, dynamic addressing with DHCPv6 and SLAAC are the methods used to configure the IPv6. The network administrator should able to understand and implement the IPv6 through the DHCPv6.

Other than the implementation, working of IPv4 and IPv6 are same. Therefore, the administrator need not to learn new information for its working.

As the IPv6 address length is 128-bit and purpose is for everything on line to have an IP address. It must allow the internet to expand faster devices to get internet access quickly.

The DHCPv6 is not supported by all windows. Therefore, network administrator should check the corresponding Operating system (OS) would support the DHCPv6 for IPv6.

The network administrator must have good knowledge and skills on the IPv6.

The above mentioned key components should be verified by the network administrator in order to support for IPv6 project with DHCPv6.

In this chapter, you saw an example of how to write an algorithm that determines whether a number is even or odd. Write a progra
vagabundo [1.1K]

Answer:

// Program is written in Java Programming Language

// Comments are used for explanatory purpose

// Program starts here

public class RandomOddEve {

/** Main Method */

public static void main(String[] args) {

int[] nums = new int[100]; // Declare an array of 100 integers

// Store the counts of 100 random numbers

for (int i = 1; i <= 100; i++) {

nums[(int)(Math.random() * 10)]++;

}

int odd = 0, even = 0; // declare even and odd variables to 0, respectively

// Both variables will serve a counters

// Check for odd and even numbers

for(int I = 0; I<100; I++)

{

if (nums[I]%2 == 0) {// Even number.

even++;

}

else // Odd number.

{

odd++;

}

}

//.Print Results

System.out.print("Odd number = "+odd);

System.out.print("Even number = "+even);

}
