• To enhance the security of the system

Which clustering configuration is known for providing load balancing?

• Active-Passive

• Active-Active

• Hybrid

• Standalone

In clustering, what does the term "failover" refer to?

• Upgrading the system to a larger cluster

• Automatically switching to a standby node if the primary node fails

• Distributing loads evenly across servers

• Removing a node from the cluster

Which of the following is NOT a typical use of clustering?

• Web services

• Databases

• Email
