The correct answers are  B. Option B  and  D. Option D . Both options B and D are compliant with PEP 8 recommendations for line breaks and indentation. PEP 8 recommends using 4 spaces per indentation level and breaking lines before binary operators. In option B, the arguments to the  print  function are aligned with the opening delimiter, which is another acceptable way to format long lines according to PEP 8. In option D, the second line is indented by 4 spaces to distinguish it from the next logical line.

In the given code snippet, the  repeat  function is a decorator that takes an argument  num_times  specifying the number of times the decorated function should be called. The  repeat  function returns an inner function  wrapper_repeat  that takes a function  func  as an argument and returns another inner function  wrapper  that calls  func   num_times  times.

The provided code snippet represents an example of a decorator that accepts its own arguments. The  @decorator_function  syntax is used to apply the  decorator_function  to the  some_function  function. The  decorator_function  takes an argument  arg1  and defines an inner function  wrapper_function  that takes the original function  func  as its argument. The  wrapper_function  then returns the result of calling  func , along with the  arg1  argument passed to the  decorator_function .

Here is an example of how to use this decorator with  some_function :

@ decorator_function ( "argument 1" )

def some_function ():

return "Hello world"

When  some_function  is called, it will first be passed as an argument to the  decorator_function . The  decorator_function  then adds the string  "argument 1"  to the result of calling  some_function()  and returns the resulting string. In this case, the final output would be  "Hello world argument 1" .

The correct answers are A and B. Option A uses a clean multi-line dictionary layout, placing each key-value pair on its own line and aligning the closing brace clearly. This is readable and consistent with PEP 8’s preference for clear continuation formatting. Option B is also compliant because continuation lines are aligned with the opening delimiter of the function call, which is an accepted PEP 8 style. Option C is not compliant because the function call is split awkwardly, making the call structure unclear and damaging readability. Option D uses unnecessary spaces inside braces and around dictionary colons; PEP 8 discourages extraneous whitespace in expressions and dictionary displays.

A. In the context of TCP/IP networks, the communication side that initiates a connection is called the client, whereas the side that answers the client is called the server.

This statement is true because TCP/IP networks use a client-server model to establish connection-oriented communications. The client is the device or application that requests a service or resource from another device or application, which is called the server. The server responds to the client’s request and provides the service or resource. For example, when you browse a website using a web browser, the browser acts as a client and sends a request to the web server that hosts the website.  The web server acts as a server and sends back the requested web page to the browser 1 .

B. Connectionless communications are usually built on top of TCP.

This statement is false because TCP (Transmission Control Protocol) is a connection-oriented protocol that requires establishing and terminating a connection before and after sending data. Connectionless communications are usually built on top of UDP (User Datagram Protocol), which is a connectionless protocol that does not require any connection setup or teardown. UDP simply sends data packets to the destination without checking if they are received or not 2 .

C. Using walkie-talkies is an example of a connection-oriented communication.

This statement is false because using walkie-talkies is an example of a connectionless communication. Walkie-talkies do not establish a dedicated channel or connection between the sender and receiver before transmitting data. They simply broadcast data over a shared frequency without ensuring that the receiver is ready or available to receive it.  The sender does not know if the receiver has received the data or not 3 .

D. A phone call is an example of a connection-oriented communication.

This statement is true because a phone call is an example of a connection-oriented communication. A phone call requires setting up a circuit or connection between the caller and callee before exchanging voice data. The caller and callee can hear each other’s voice and know if they are connected or not.  The phone call also requires terminating the connection when the conversation is over 4 .

ConfigParser is a built-in library in Python that allows you to read and write configuration files. The read method is used to read the configuration file which can be in any of the supported file formats, such as INI, YAML, and JSON. The read_dict method is used to read the configuration from a Python dictionary. The read_conf and read_str options are not valid methods in the ConfigParser module.

Therefore, the correct options to load a configuration using ConfigParser are A. read and D. read_string.
