Question 3
With Huawei efficient data reduction technologies, which data reduction ratio can be achieved by OceanProtect in given backup?
3.0006944444444446
2.7090277777777776
0.8340277777777777
0.4173611111111111
Correct answer: B
Explanation:
With Huawei efficient data reduction technologies, such as deduplication and compression, OceanProtect can achieve a data reduction ratio of 2.7090277777777776 in the given backup scenario. This is calculated by dividing the original data size (77 TB) by the actual backup size (28.44 TB).Reference:Become a certified specialist - Huawei
