Question 2

Company A constructed a sales management platform using three Elastic Compute Service (ECS) instances. One of the instances runs MySQL, and is used as the database server. The other two instances are used as Web servers After some time, the number of employees in Company A dramatically increases, leading to higher sales volumes At the same time, the platform response speed is gradually decreasing too.

According to the report from CloudMonitor, the average CPU utilization rate of the two Web servers exceeds 70%, and database load

reaches 75% Company A can select Alibaba Cloud_________ services.to cope with the issue and optimize the performance. (Number of correct answers: 2)

AImport database data into Object Storage Service (OSS) to share the storage pressure on the platform

BIncorporate Server Load Balancer (SLB) and add additional ECS instances to relieve the load on existing ECS instances

CUse Content Delivery Network (CDN) to enhance content loading speed

DReplace the self-built MySQL database with ApsaraDB for RDS to obtain better database performance, and utilize RDS read-only instances to handle read-only requests

Answer : B, D

Question 3

Before data communication is setup, the security groups match the security group rules one by one to query whether to allow access requests Assume that the user has created two security group rules 1 and 2 The protocol type, port range, authorization type, and authorization object of the two security group rules are the same. The difference is that Rule 1 is a denial policy, rule 2 is an allowed policy, so the following statement is correct_______ (Number of correct answers 2)

AIf rule 1 and rule 2 have the same priority, the rule of the denial policy takes effect first, and the rule of the allowed policy does not take effect

BIf rule 1 and rule 2 have the same priority, the rule of the allowed policy takes effect first, and the rule that of the denial policy does not take effect.

CIf rule 1 and rule 2 have different priorities, the rule with a small priority number takes effect

DIf rule 1 and rule 2 have different priorities, the rule with a large priority number takes effect.

Answer : A, C

Question 4

A large enterprise wants to migrate the entire business system to Alibaba Cloud to save the overall IT procurement and O&M costs From the security aspect, the company requires that

1. Must support secured remote O&M because the administrator often takes business trips.

AEnable the VPN on the bastion host (or directly use the VPN image on Alibaba Cloud Marketplace). The administrator uses VPN encrypted communication during O&M.

BBuild an independent ECS instance as the bastion host or remote logon and O&M, and authorize the bastion host to access ECS instances running other subsystems.

CUse the security group function of the ECS instance, and respectively deploy ECS instances running different subsystems to independent security groups.

DCreate multiple ECS instances in the VPC to install subsystems of different departments- Allocate only Intranet IP addresses to all ECS instances, and deploy them in the same security groups.

Answer : A, B, D

Question 5

Alibaba Cloud Server Load Balancer (SLB) provides services for distributing traffic among multiple ECS instances SLB can expand the application system's service capacity through traffic distribution, and improve the system's availability by eliminating SPoFs (Single Points of Failure). Which of the following statements are correct? (Number of correct answers; 2)

AOne of SLB's features is the Health Check. If some of the backend ECS instances are down, whereas other backend ECS instances can still provide services, then the system can continue to work normally.

BWhen recreating an SLB instance that has an Internet IP address, a new Internet IP address will be assigned to the SLB instance.

CBefore using SLB to provide external services, make sure that you have installed and correctly configured the SLB agent on all of the backend ECS instances.

DSLB provides a function to automatically synchronize data among backend ECS instances using rsync remote synchronization.

Answer : A, D

Question 6

ACreate a scaling rule

BCreate a scheduled task.

CCreate a new scaling group.

DCreate an event-triggered task.

Answer : C
