2 TB for high-performance, 15 TB for mid-tier, 200 TB for low-cost

Question 12

A data center is experiencing slow backup operations due to high I/O contention on its storage system. The backup administrator is tasked with improving the performance of the backup jobs. After analyzing the current setup, the administrator identifies that the backup jobs are running during peak hours when the storage system is heavily utilized for production workloads. To optimize the backup performance, which of the following strategies should the administrator implement?

Accepted Answer

Schedule backup jobs during off-peak hours to reduce I/O contention.

Question 13

In a decentralized application (dApp) designed for data management using smart contracts, a company wants to automate the process of data access permissions based on user roles. The smart contract is programmed to grant access to specific datasets based on the user\'s role, which can be either \"admin,\" \"editor,\" or \"viewer.\" The contract also includes a mechanism to log every access attempt, recording the user ID, timestamp, and the type of access requested. If a user with the \"viewer\" role attempts to access a dataset that requires \"editor\" permissions, the contract should deny access and log the attempt. Given this scenario, which of the following best describes the primary advantage of using smart contracts for this data management process?

Accepted Answer

Smart contracts ensure that access control is enforced automatically and transparently without the need for intermediaries.

Question 14

In a cloud-based data protection strategy, an organization is evaluating the effectiveness of different backup methods to ensure data integrity and availability.
