Question
Which of the following configurations is aimed at increasing data availability and protecting a storage system from becoming unavailable due to a partial network outage?
Options
- ARedundant SFPs
- BMultipathing
- CHot swappable storage enclosures
- DDual power supply
Explanation
Multipathing is a configuration designed to increase data availability and protect storage systems from becoming unavailable due to partial network outages.
Common mistakes.
- A. Redundant SFPs contribute to overall network reliability but do not, by themselves, create multiple logical data paths for failover in the same way multipathing does.
- C. Hot swappable storage enclosures allow for component replacement without downtime, which improves hardware maintenance and availability but does not protect against network path outages.
- D. Dual power supplies provide power redundancy for a device, preventing downtime due to a power supply failure, but they do not address failures in data transmission paths.
