Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Failover: Automatic switching to a redundant system upon failure
Correct matches: Failover (auto-switch to standby), Load Balancing (distribute workload), Clustering (group as one system), Redundancy (duplicate components). Common confusions: swapping failover and load balancing definitions.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Failover: Automatic switching to a redundant system upon failure
Why this is correct
Failover ensures continuity by automatically transferring control to a standby system when the primary fails.
Load Balancing: Distributing workloads across multiple resources
Why this is correct
Load balancing spreads demand across servers to optimize resource use and prevent overload.
Clustering: Grouping servers to appear as a single system
Why this is correct
Clustering combines multiple servers to work together, providing high availability and scalability.
Redundancy: Duplicating components to eliminate single points of failure
Why this is correct
Redundancy involves having backup components so that failure of one does not cause system downtime.
Failover: Distributing workloads across multiple resources
Why it's wrong here
Incorrect — this describes load balancing, not failover.
Load Balancing: Automatic switching to a redundant system upon failure
