The choices are a) credible website B)search log c) Boolean operator d) online database.
The answer is, d. Online database. There are already numerous online digital tools that can aid research. Examples are readcube, mendeley, google scholar. It helps you save and organize researches as well as automatically give bibliographies according to your need like APA and MLA. These tools can hold and save different information that researchers need.
The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program in C++ where comments are used to explain each line is as follows:
#include <iostream>
using namespace std;
int main(){
//This declares and initializes all variables
string star = "*", blank = " ", temp;
//The following iteration is repeated 8 times
for (int i = 1; i <= 8; i++) {
//The following iteration is repeated 8 times
for (int j = 1; j <= 8; j++) {
//This prints stars
if (j % 2 != 0) {
cout << star;
}
//This prints blanks
else if (j % 2 == 0) {
cout << blank;
}
}
//This swaps the stars and the blanks
temp = star;
star = blank;
blank = temp;
//This prints a new line
cout << endl;
}
}

Answer:
If you code a column list in an INSERT statement that includes a column that’s defined with a default value, you can insert the default value for that column by coding the DEFAULT keyword in the VALUES clause of the INSERT statement.
Explanation:
SQL permits insert the DEFAULT value on the columns when is required. Suppose the column has a NULL constraint(values on this column can not be set in null), then you can pass the default value.
For example:
INSERT INTO table(field1, field2, field3, field4) VALUES (10, DEFAULT, 20, DEFAULT)
C) Filters make it easier to find specific information in large databases.
Answer:
Allow VLAN 20 on the trunk link.
Explanation:
Enable DTP on both ends of the trunk by allowing VLAN20 on the trunk link.
From curriculum topic: 3.2.4
To Enable DTP on both switches is simply allowing the negotiation of trunking. The "Negotiation of Trunking" line in the graphic is what shows that DTP is already enabled. The graphic also shows how the native VLAN is 1, and the default VLAN for any Cisco switch is 1. The graphic shows the PCs are to be in VLAN 20.
This will remedy the problem.
