RabbitMQ - Performance Tuning

Given the following Python code snippet using pika:

import pika
connection = pika.BlockingConnection(pika.ConnectionParameters())
channel1 = connection.channel()
channel2 = connection.channel()
print(channel1.is_open, channel2.is_open)
channel1.close()
print(channel1.is_open, channel2.is_open)

What will be the output?

ATrue False\nFalse False

BTrue True\nFalse False

CFalse False\nFalse False

DTrue True\nFalse True

Step-by-Step Solution

Solution:

Step 1: Check initial channel states
Both channels are open after creation, so first print shows True True.
Step 2: Close channel1 and check states
Closing channel1 sets its is_open to False; channel2 remains open True.
Final Answer:
True True\nFalse True -> Option D
Quick Check:
Closing one channel doesn't close others [OK]

Quick Trick: Closing one channel doesn't affect others [OK]

Common Mistakes:

MISTAKES

Assuming closing one channel closes all
Confusing is_open states after close
Expecting both channels to close automatically
