AWS Certified Solutions Architect Associate (SAA-C03) - Load Balancer Concepts

The video tutorial introduces the concept of load balancing, its history, and how it functions. It explains the different types of load balancing, including sender and receiver initiated, and compares static and dynamic load balancing. Various algorithms used in load balancing, such as round robin and randomized, are discussed. The tutorial also covers practical considerations for implementing load balancing, including the importance of synchronized storage.

What is the primary purpose of load balancing in a system?

• To reduce the number of users

• To distribute tasks across multiple servers

• To enhance the security of the system

• To increase the number of servers

Which component is responsible for directing incoming requests to the appropriate server?

• Web server

• Client node

• Database

• Load balancer

In sender-initiated load balancing, who decides the best target server?

• The sender

• The database

• The load balancer

• The receiver

What is a characteristic of static load balancing?

• Randomized task distribution

• Fixed assignment of tasks

• Dynamic assignment of tasks

• Scalability

Which algorithm rotates requests through servers in a fixed order?

• Threshold-based

• Round robin

• Centrally managed

• Randomized

What is a key consideration when implementing load balancing to ensure data consistency?

• Increasing the number of servers

• Using a single server for all tasks

• Ensuring synchronized storage

• Reducing the number of requests

Which load balancing algorithm considers the current state of the environment to make decisions?

• Centrally managed

• Randomized

• Round robin

• Threshold-based
