CompTIA Security+ Certification SY0-601: The Total Course - Load Balancing

The video tutorial explains the concept of load balancing, emphasizing its role in improving performance and availability. It covers the configuration of load balancers, including client connections, DNS resolution, and IP addressing. The tutorial also discusses autoscaling and horizontal scaling, highlighting the addition and removal of virtual machines based on demand. Session persistence and scheduling methods like round robin and least connection are explained, along with active-active and active-passive configurations. The video concludes with considerations for configuring load balancers based on application needs.

What is the primary benefit of using a load balancer in an application?

• To improve performance and availability

• To decrease the cost of hardware

• To reduce the number of servers needed

• To increase the complexity of the network

What does autoscaling in a load balancer allow you to do?

• Add or remove servers based on demand

• Reduce the number of client requests

• Decrease the load on the network

• Increase the speed of individual servers

What is the term for adding virtual machine nodes to support increased demand?

• Scaling out

• Scaling in

• Scaling up

• Scaling down

What does session persistence in a load balancer ensure?

• Clients are always connected to the fastest server

• Clients remain connected to the same server during a session

• Clients can switch servers freely during a session

• Clients are connected to the least busy server

In an active-active load balancing configuration, what is the state of the servers?

• All servers are in standby mode

• Servers are activated based on client requests

• Only one server is active at a time

• All servers are active and ready simultaneously

How does the round-robin scheduling method distribute client requests?

• By sending all requests to the first server

• By sending requests to each server in turn

• By sending requests to servers based on their power

• By sending requests to the least busy server

What is the purpose of a standby server in an active-passive configuration?

• To handle all client requests

• To reduce the number of active servers

• To be ready in case an active server fails

• To increase the speed of active servers
