Which IPsec security function provides assurance that the data received via a VPN has not been modified in transit?

1 answer:

3 0

Integrity IPsec security function provides assurance that the data received via a VPN has not been modified in transit.

Explanation:

IPsec utilizes cryptographic security administrations to ensure interchanges over Internet Protocol (IP) systems. It underpins organize level friend validation, information beginning confirmation, information honesty, information classification (encryption), and replay assurance. ESP gives confirmation, respectability, and secrecy, which ensure against information altering and, in particular, give message content security.

Moreover, parcels that are not confirmed are disposed of and not conveyed to the planned recipient. ESP likewise gives all encryption benefits in IPSec. IPsec Authentication Header (AH), IPsec Encapsulating Security Payload (ESP), and the IPsec Internet Key Exchange (IKE). for both IPv4 and IPv6 systems, and activity in the two adaptations is comparative.

Fill in the blanks, so the print statement displays the result of the function call in order.

Answer:

Rep;ace the blank with

smaller, bigger

So, the complete line is:

smaller,bigger=order_numbers(100,99)

Explanation:

From the question, we understand that the program is to return the order of a number from least to highest

This has been well implemented in order_numbers function

Because the order function returns two values, the order_function must be called in order to accept two values and the syntax is:

value1,value2 = function(return-value1,return-value2)

In this case, the statement is:

smaller,bigger=order_numbers(100,99)

So, in the next line of the main, the values of smaller and bigger are printed:

print(smaller,bigger)

Answer and Explanation:

package PackageDemo;

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;

import org.apache.hadoop.fs.Path;

import org.apache.hadoop.io.IntWritable;

import org.apache.hadoop.io.LongWritable;

import org.apache.hadoop.io.Text;

import org.apache.hadoop.mapreduce.Job;

import org.apache.hadoop.mapreduce.Mapper;

import org.apache.hadoop.mapreduce.Reducer;

import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;

import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;

import org.apache.hadoop.util.GenericOptionsParser;

public class WordCount {

public static void main(String [] args) throws Exception

{

Configuration c=new Configuration();

String[] files=new GenericOptionsParser(c,args).getRemainingArgs();

Path input=new Path(files[0]);

Path output=new Path(files[1]);

Job j=new Job(c,"wordcount");

j.setJarByClass(WordCount.class);

j.setMapperClass(MapForWordCount.class);

j.setReducerClass(ReduceForWordCount.class);

j.setOutputKeyClass(Text.class);

j.setOutputValueClass(IntWritable.class);

FileInputFormat.addInputPath(j, input);

FileOutputFormat.setOutputPath(j, output);

System.exit(j.waitForCompletion(true)?0:1);

}

public static class MapForWordCount extends Mapper<LongWritable, Text, Text, IntWritable>{

public void map(LongWritable key, Text value, Context con) throws IOException, InterruptedException

{

String line = value.toString();

String[] words=line.split(",");

for(String word: words )

{

Text outputKey = new Text(word.toUpperCase().trim());

IntWritable outputValue = new IntWritable(1);

con.write(outputKey, outputValue);

}

public static class ReduceForWordCount extends Reducer<Text, IntWritable, Text, IntWritable>

{

public void reduce(Text word, Iterable<IntWritable> values, Context con) throws IOException, InterruptedException

{

int sum = 0;

for(IntWritable value : values)

{

sum += value.get();

}

con.write(word, new IntWritable(sum));

_____ is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it

babymother [125]

Answer:

Case-based reasoning.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.

Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.
