A company runs a critical application on a two-node cluster configured in an active/passive failover arrangement. The active node fails unexpectedly. Which of the following BEST describes what happens next in this configuration?
- ABoth nodes process traffic simultaneously to share the load
- BThe passive node automatically takes over processing to maintain availability
- CTraffic is rerouted to a geographically distant disaster recovery site
- DThe application remains offline until an administrator manually restarts the failed node
Show answer & explanationAnswer & explanation
Correct answer: B. The passive node automatically takes over processing to maintain availability
In an active/passive failover cluster, one node handles traffic while the standby (passive) node remains idle but ready; when the active node fails, the passive node automatically takes over to preserve availability with minimal downtime.
Why the other options are wrong
- A. Simultaneous processing describes active/active, not active/passive.
- C. This describes site-level disaster recovery, not local cluster failover.
- D. Automatic failover clusters are designed to avoid requiring manual intervention.
Active/Passive Failover Clustering
A high-availability configuration where a standby node automatically assumes the workload of a failed active node to minimize downtime.
- Passive node stays idle until failover is triggered.
- Failover is typically automatic, not manual.
- Contrasts with active/active, where both nodes process traffic simultaneously.
Memory trick: One works, one waits, ready to jump in.
