Answer:
The network is accesible just for the whitelisted clients configured in the switch connected to the DHCP server
Explanation:
DHCP snooping main task is to prevent an unauthorized DHCP server from entering the our network.
Basically, in the switch we define the ports on which the traffic of the reliable DHCP server can travel. That is, we define as “trust” the ports where we have DHCP servers, DHCP relays and trunks between the switches.
Answer:
A view is an application
program’s or an individual user’s picture of the database.
It is less involved than the full database.
If a user accesses a database through a view they can only view data but cannot make any changes to the structure of the database
Answer:
To ensue that data entering data is limited, Usually A dropdown list is used but here in the available option
Lookup list is correct.
Explanation:
Let explain why we have selected Lookup list
A lookup list is used to look for some value in a list.
For example in Excel we select a column for search which is basically limiting the value which we search.
Bound Value
we usually have 2 bounds ,
lower and upper bound
lower bound is the smallest value in a set while upper bound it the highest value in a set.
Short Text:
Short text is used to minimize the word.
For example instead of United States we simply write US
Date/Time are used for data/time value.
so the most appropriate answer is Lookup list.
Answer:
import java.util.Scanner;
public class CocaColaVendingTest {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter four sepertate binary numbers (1 or 0)");
int b0 = in.nextInt();
int b1 = in.nextInt();
int b2 = in.nextInt();
int b3 = in.nextInt();
System.out.println("This formula \"8b0 4b1 2b2 b3\" is applied to get the following" +
" "+(8*b0)+", "+(4*b1)+", "+(2*b2)+", "+(b3));
}
}
Explanation:
This is implemented in java
Using the scanner class, the user is prompted to enter for values (0s or 1s)
These are received and stored in the variables b0, b1,b2,b3 as ints.
The formula 8b0 4b1 2b2 b3 is then applied within the output statement to display the results as required by the question
