Sample ACA-Cloud1 Questions

Practice with real exam-style questions. Reveal answers to verify your knowledge.

Q1 MultipleChoice

Alibaba Cloud Object Storage Service (OSS) is a massive, highly available, secured and cost effective storage service. OSS is superior than self-built storage in all these aspects. Which of the following advantage relates

to the high availability of OSS?

AAvailability actually relies on the underlying hardware, which can break down easily. Once the hard disk malfunctions, it can also lead to permanent data loss.

BData Reliability is not less than 99.99999999%. Data is backed up automatically with multiple redundant copies.

CData has to be backed up by customer manually, which is time-consuming and labor-intensive.

DThe following features are available: Multiple Authentication and Authorization mechanism, Whitelist, Anti- leech URL, and Master-Sub Account

Q2 MultipleChoice

Alibaba Cloud's object storage (Object Storage Service, OSS for short) can be used to store massive amount of files, but there is still a maximum number of files in a single bucket.

ATRUE

BFALSE

Q3 MultipleChoice

Which of the following statements about file uploading to OSS strategy is not correct?

AAll file uploading method provided by Alibaba Cloud OSS service will support resuming from break point.

BIf you are uploading some small files (<1m), you can choose using put method to be able finish uploading in one http request.

CIf you are using OSS to store some log files which are continuously being updated, you better choose
streaming method to be able to append to one existing object instead of overwriting.

DIf you need to upload very large file you better use multi-part uploading to get the capability of resuming from break point.

Q4 MultipleChoice

When using Alibaba Cloud SLB, you can set different weights for backend ECS instances. The higher the weight of a backend ECS instance, the more load will be assigned to it. If an SLB instance has 5 ECS instances in the backend server pool, all of which are healthy. Among these 5 ECS instances, the weight of ecs_inst1 is set to 100. Which of the following statements is correct?

AWe do not know the weight settings of the remaining 4 ECS instances, so we cannot tell what would happen.

B100% of loads will be assigned to ecs_inst1, and the rest 4 ECS instances will stay idle.

CBased on SLB's working mechanism, approximately 20% of loads will be assigned to ecs_inst1.

DBased on request level parameters of external requests, all requests with a request level parameter of 100 will be transferred to ecs_inst1.

Q5 MultipleChoice
