Answer:

It gives a new string

Explanation:

In programming; when two or more strings are concatenated by a concatenating operator, the result is always a new string.

From the question, we have that

str1 = "Good

str2 = "Evening"

Let's assume that + is the concatenating operator;

str1 + str2 = "Good" + "Evening" = "GoodEvening"

The result of concatenating str1 and str2 is a new string "GoodEvening" while str1 and str2 still maintain their original string value of "Good" and "Evening"

The readline method reads text until an end of line symbol is encountered, how is an end of line character represented
zhannawk [14.2K]

Answer:

\n

Explanation:

readline() method is used to read one line from a file. It returns that line from the file.    

This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.

So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.

For example if the file "abc.txt" contains the lines:

Welcome to abc file.

This file is for demonstrating how read line works.

Consider the following code:

f = open("abc.txt", "r")  #opens the file in read mode

print(f.readline()) # read one line from file and displays it

The output is:

Welcome to abc file.    

The readline() method reads one line and the print method displays that line.

You want high availability for DHCP services, a primary server to handle most DHCP requests, and a secondary server to respond t
babymother [125]

Answer:

The blocking system.

Explanation:

In order to avoid servers to replicate with each other, I should configure the blocking system of the first DHCP.

For example, if the first DHCP fails to respond, the second will get in place, however, I have to configure the first system that immediately that the second DHCP starts working, the first blocks its information and use.

By this way, there won´t be any duplicated actions or reponses.
