Python Thread Synchronization

Question 1

What is the purpose of a lock in python threading module?

It is used to create new threads.

It ensures that only one thread can access a shared resource at a time.

It sets the priority of a thread.

It is used to create daemon threads.

Question 2

Which of the following is a common issue that thread synchronization aims to prevent in multithreaded python programs?

Excessive CPU utilization

Deadlocks

Excessive memory usage

Reduced thread priority

Question 3

What is the primary goal of thread synchronization in python?

To increase the number of threads in a program.

To ensure that multiple threads can execute concurrently without interference.

To eliminate the need for using threads in python.

to make all threads run as daemon threads.

Question 4

Which method is used to release a lock in python's threading module?

unlock()

release()

free()

Lock are automatically released when a thread finishes.

Question 5

What is a mutex in the context of thread synchronization in python?

A type of threads.

A function to create threads.

A synchronization primitive used to protect shared resources.

A type of daemon thread.

Question 6

What is the purpose of a condition in python's threading module?

It is used to check the condition of a thread.

It is used to create a thread.

It allows threads to wait for a specific condition to be met before continuing execution.

It is used to define thread priority.

Question 7

Which python module provides synchronization primitives like lock, semaphore, and condition for managing thread synchronization?

threading

multiprocessing

synchronization

concurrent

Question 8

What happens when a thread tries to acquire a lock that is already held by another thread?

The new thread is suspended until the lock is released .

The new thread forcefully acquires the lock.

Both threads can access the lock concurrently.

Python raises an exception.

Question 9

In python ,how can you acquire a lock for exclusive access to shared resource?

Call the acquire() method on the lock object.

Use the lock() function.

Locks are acquired automatically by python threads.

Call the claim() method on the lock object.

Question 10

Which synchronization primitive in python can be used to limit the number of concurrent threads that can access a resource?

Lock

Semaphore

Condition

Barrier

Name

Phone
