N10-005 Question #785: Real Exam Question with Answer & Explanation
The correct answer is B: High availability. High availability describes an architecture that uses redundant components and fault detection to minimize downtime and ensure continuous system operation.
Question
A technician sets up a network with multiple WAN connections, backup power sources, multiple firewalls, and a mesh configuration for network switching. All of the software and hardware has fault detection designed to provide a system with minimal down time. Which of the following is the BEST example of this optimization method?
Options
- ALoad balancing
- BHigh availability
- CCaching engines
- DQuality of Service
Explanation
High availability describes an architecture that uses redundant components and fault detection to minimize downtime and ensure continuous system operation.
Common mistakes.
- A. Load balancing distributes traffic or workloads across resources to improve performance - it is one component that can contribute to HA but does not describe the overall redundancy architecture by itself.
- C. Caching engines store data locally to improve response times and reduce upstream load - they are not a fault-tolerant or redundancy strategy.
- D. Quality of Service prioritizes certain traffic types to ensure performance for critical applications - it does not address hardware redundancy or fault tolerance.
