Discuss Alibaba ACA-Developer Exam Topic 9 Question 7

Which of the following options is correct, regarding Object ACL in Alibaba Cloud's Object Storage Service (OSS)?

AObject ACL is an object-level (not bucket level) permission control mechanism. There are currently three levels of access rights: private, public-read, and public-read-write.

B'Private' indicates that an object is a private resource, that is, only the owner of the object has read and write permissions on the object, and other users can read but have no permission to modify or delete the object.

CIf the permissions of an object are not set, the permissions of the object are inherited from the bucket.

DYou can set the ACL associated with an object by examining the X-OSS-Object-ACL header in the HEAD request, when making the PutObjectACL API call.

Wait, are there really only three access levels? That seems low.

D is interesting, didn't know you could check ACL via the header!

C sounds right, permissions do inherit from the bucket if not set.

I think B is misleading, 'private' means no one else can access it at all.

A is correct, Object ACL is indeed object-level.

I think this question is asking about a specific feature of the Traps product, so I'll need to focus on understanding the terminology used in that context.

I think it could be denial of service, but I'm a bit uncertain. There were so many terms in that section.

Hmm, this one's tricky. I'm not sure if the personal use of the cabin for 3 months affects the calculation in any way. I'll have to think about that a bit more. But based on the numbers given, I'm leaning towards option B) $500 as the rental loss.

Hmm, this seems like a tricky one. I'll need to carefully read through the details and think about the requirements.

I remember we had similar questions on focusing actions in data policies, but I can't recall if "C" for accept would actually capture packets.
