Discuss Huawei H19-308_V4.0 Exam Topic 5 Question 12

What are the advantages of object storage over traditional NAS storage? (Select all that apply)

AHTTP/HTTPS is more universal than NFS/CIFS and supports Internet access.

BCustomized metadata is easy to manage.

CTree-shaped directories and hierarchical management are easy to understand.

DThe flat structure is easy to expand.

Suggested Answer: A, B, D

Huawei documentation highlights several key advantages of object storage for modern data requirements. Option A is correct because object storage primarily uses RESTful APIs (HTTP/HTTPS), which are firewall-friendly and accessible globally over the internet, unlike NFS/CIFS/SMB which are generally restricted to local area networks (LANs).

Option B is correct because object storage allows for extensible metadata. Users can attach custom tags to objects, enabling powerful data searching and automated lifecycle management without needing an external database to track file attributes. Option D is correct because object storage uses a flat namespace rather than the tree-shaped directory structure of NAS. In a flat structure, adding more nodes to the system does not increase the complexity of data retrieval, allowing for nearly infinite horizontal scalability. Option C is incorrect in this context because the tree-shaped directory is actually a limitation of NAS that causes performance degradation at high scales, whereas object storage avoids this hierarchy to improve expansion capabilities.

I disagree with C, I find tree structures easier to navigate.

Ardella 3 months ago

A is definitely true, HTTP/HTTPS is everywhere!

Tree-shaped directories are usually easier to navigate, but I think that might be more of a NAS feature than an advantage of object storage.

I feel like the flat structure makes scaling easier, but I can't recall if that was mentioned in the practice questions.

I think customized metadata is definitely a strong point for object storage. It allows for better organization, right?

I remember reading that HTTP/HTTPS being more universal is a big plus for object storage, but I'm not sure if it's the only advantage.
