TRUE

FALSE

10. Which of the following statements is wrong when comparing RDS with self-built database?

RDS features a high availability of 99.95% while self-built database requires you toimplement data protection, primary-standby replication, and RAID all by yourself.

RDS provides automatic backup while self-built database requires you to prepare storage space for backup copies and regularly verify that these copies can be restored.

Self-built database supports quick deployment and elastic scaling.

RDS requires no O&M while self-built database requires a dedicated DBA for maintenance, which results in high HR cost.

11. You are developing a highly available web application using stateless web servers.

Which services are suitable for the application? (Choose three.)

RDS

SLB

ECS

MaxCompute

OSS

Resources are not shared among the databases in the same RDS instance.

None of the above is true.

13. Which of the following scenarios is applicable to use RDS read-only instances?

Reduces the read pressure on the RDS primary instance.

Implements data backtracking for the last two days.

Improves RDS storage capabilities.

14. 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?

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

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

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

Which of the following statement about OSS backup is correct?

OSS supports 3 internal data copies, so the data can be manually recovered should there be any problem.

Customer has to safeguard their own data. OSS provides various backup interfaces to facilitate offsite backups.

OSS leverages RAID0+1 configuration of its underlying physical hard disks. There is no impact even if 2 hard disks were to fail simultaneously.

OSS supports 3 internal data copies, no human intervention is required to recover the data when anything goes wrong.

18. A video streaming company uses SLB to distribute user requests to 30 ECS instances (the 30 ECS instances have the same configuration). Yet, the company finds that the service traffic soars dramatically every night from 20:00 to 02:00.

To properly respond to user requests, which of the following methods is most preferred from the perspective of cost and implementation simplicity?

Configure Auto Scaling appropriately to automatically add or reduce ECS instances.

Manually create 30 ECS instances using the custom image, and then add them to SLB every night before 20:00 and remove them after 02:00.

Create 30 ECS instances based on the custom image and add them to SL

Then, configure weights for these ECS instances to respond to user requests every night from 20:00 to 02:00, and reset those weights to zero for other periods of time.
