200-201 Question 128
Single answerA cybersecurity analyst is tasked with implementing load balancing to ensure high availability and optimal performance for a web application hosted on multiple servers. The analyst is considering different load balancing algorithms. Which of the following algorithms is LEAST likely to provide efficient load distribution in environments where servers have varying performance capabilities?
- A
Round Robin
- B
Least Connections
- C
Weighted Round Robin
- D
Dynamic Load Balancing
Show answer and explanation
Correct answer: A
Explanation
Round Robin is the least effective algorithm in environments with servers of varying performance capabilities because it blindly distributes traffic equally without considering real-time resource availability or server performance. Other algorithms such as Least Connections, Weighted Round Robin, and Dynamic Load Balancing adapt to server conditions and ensure more efficient traffic distribution.
- A. Correct.
Round Robin distributes traffic equally among all servers, without considering their current load or performance capabilities. This can result in inefficient load distribution if servers have varying performance capabilities.
- B. Incorrect.
Least Connections distributes traffic based on the number of active connections to each server, making it more efficient in environments where servers have varying performance capabilities.
- C. Incorrect.
Weighted Round Robin considers predefined weights assigned to servers, allowing it to accommodate servers with different performance capabilities effectively.
- D. Incorrect.
Dynamic Load Balancing monitors real-time server health and performance to ensure intelligent traffic distribution, making it highly efficient in environments with varying server performance.
