NEW QUESTION # 34
What is the result of the following code?
PCPP-32-101-540bdc935722302eaef330da4832aecf.jpg
What is the result of the following code?

  • A. Nothing will be displayed
  • B. Loading data...
  • C. Debugging mode has been enabled Loading data...
  • D. Debugging mode has been enabled

Answer: B

Explanation:
Explanation
This statement is true because the code uses the logging module to create a logger object and set its level to logging.INFO. The logging module provides a way of reporting events that occur during the execution of a program. The logging level determines which events are reported and which are ignored. The logging module defines five levels of severity: DEBUG, INFO, WARNING, ERROR, and CRITICAL. The lower the level, the more events are reported.
The code then uses the logger object to log two messages: one with the level logging.DEBUG and one with the level logging.INFO. The logger object only reports the messages that have a level equal or higher than its own level. Therefore, the message with the level logging.DEBUG is ignored, while the message with the level logging.INFO is reported. The default format for reporting messages is "level name: message". Therefore, the output of the code is:
INFO: Loading data...


NEW QUESTION # 35
Select the true statements about sockets. (Select two answers)

  • A. A socket is always the secure means by which computers on a network can safely communicate, without the risk of exposure to an attack
  • B. A socket can be used to establish a communication endpoint for processes running on the same or different machines.
  • C. A socket is a connection point that enables a one-way communication only between remote processes
  • D. A socket is a connection point that enables a two-way communication between programs running in a network.

Answer: B,D

Explanation:
Explanation
A socket is a connection point that enables a two-way communication between programs running in a network.
This statement is true because a socket is a software structure that serves as an endpoint for sending and receiving data across a network. A socket is defined by an application programming interface (API) for the networking architecture, such as TCP/IP. A socket can be used to establish a communication channel between two programs running on the same or different network nodes12.
A socket is always the secure means by which computers on a network can safely communicate, without the risk of exposure to an attack.
This statement is false because a socket by itself does not provide any security or encryption for the data transmitted over the network. A socket can be vulnerable to various types of attacks, such as eavesdropping, spoofing, hijacking, or denial-of-service. To ensure secure communication, a socket can use additional protocols or mechanisms, such as SSL/TLS, SSH, VPN, or firewall3.
A socket is a connection point that enables a one-way communication only between remote processes.
This statement is false because a socket can enable both one-way and two-way communication between processes running on the same or different network nodes. A socket can be used for connection-oriented or connectionless communication, depending on the type of protocol used. For example, TCP is a connection-oriented protocol that provides reliable and bidirectional data transfer, while UDP is a connectionless protocol that provides unreliable and unidirectional data transfer12.
A socket can be used to establish a communication endpoint for processes running on the same or different machines.
This statement is true because a socket can be used for inter-process communication (IPC) within a single machine or across different machines on a network. A socket can use different types of addresses to identify the processes involved in the communication, such as IP address and port number for network sockets, or file name or path for Unix domain sockets12.

NEW QUESTION # 36
Select the true statements about the connection-oriented and connectionless types of communication. (Select two answers.)

  • A. Using walkie-talkies is an example of a connection-oriented communication
  • B. A phone call is an example of a connection-oriented communication
  • C. 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
  • D. Connectionless communications are usually built on top of TCP

Answer: B,C

Explanation:
Explanation
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 browser1.
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 not2.
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 not3.
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 over4.

https://en.wikipedia.org/wiki/Walkie-talkie 4: https://en.wikipedia.org/wiki/Telephone_call A is true because in the context of TCP/IP networks, the communication side that initiates a connection is called the client, and the side that answers the client is called the server. This is the basis for establishing a connection-oriented communication.
D is true because a phone call is an example of a connection-oriented communication. Like TCP/IP, a phone call establishes a connection between two devices (in this case, two phones) before communication can occur.
A is true because in the context of TCP/IP networks, the communication side that initiates a connection is called the client, and the side that answers the client is called the server. This is the basis for establishing a connection-oriented communication.
D is true because a phone call is an example of a connection-oriented communication. Like TCP/IP, a phone call establishes a connection between two devices (in this case, two phones) before communication can occur.
B is false because connectionless communications are usually built on top of UDP, not TCP. UDP is a connectionless protocol that does not establish a connection before sending data.
C is false because using walkie-talkies is an example of a connectionless communication. Walkie-talkies do not establish a connection before communication begins, and messages are simply broadcasted to all devices within range.
Here is a sample code in Python using the socket module to create a TCP server and client to demonstrate the connection-oriented communication:
Server-side code:
importsocket
HOST ='127.0.0.1'
PORT =8080
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.bind((HOST, PORT))
s.listen()
conn, addr = s.accept()
with conn:
print('Connected by', addr)
whileTrue:
data = conn.recv(1024)
ifnotdata:
break
conn.sendall(data)
Client-side code:
importsocket
HOST ='127.0.0.1'
PORT =8080
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.connect((HOST, PORT))
s.sendall(b'Hello, world')
data = s.recv(1024)
print('Received',repr(data))
The server listens for incoming connections on port 8080, and when a connection is established, it prints the address of the client that has connected. The server then continuously receives data from the client and sends it back to the client until the connection is closed.
The client establishes a connection with the server and sends the message "Hello, world" encoded as bytes. It then waits for a response from the server and prints the data it receives.
