Final answer:
d) All of the mentioned. Cloud-based storage systems are highly reliable due to features such as redundant networks, redundant name servers, and replication of data, all of which contribute to the robustness and availability of the service.
Step-by-step explanation:
You asked which features make cloud-based storage systems highly reliable. The correct answer is d) All of the mentioned.
Cloud-based storage systems deploy several strategies to ensure high reliability and data availability. These strategies include:
Redundant networks, which help to prevent downtime due to network failures by having multiple pathways for data transmission.
Redundant name servers, which ensure that even if one server goes down, another can take over to keep services running smoothly.
Replication of data, which means that copies of data are stored in multiple locations to prevent data loss in case of hardware failure or other issues.
Each of these features contributes to the robustness and dependability of cloud storage services, providing users with continuous access to their data.
