Q17. A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group He/she sets the “Minimum number of instances” to 2 and “Maximum number of instances” to 7.
After correctly configuring scaling settings, the customer adds a scaling rule “Add 6 ECS instances”, and creates a scheduled task based on this rule.
And then, the customer checks the scaling group and see it already contains 3 valid ECS instances, he/she then enables this scaling group immediately.

True

False

Q19. Which of the following privilege is required to manually install Alibaba Clod Security Center on the server?

Q20. If you need to accelerate a certain domain name (such as abc.com) via Alibaba Cloud Content Delivery Network (CDN), you must add it to “CDN Domain Name List” in the CDN service. After added successfully, you will get a CNAME address A Next, you need to modify domain name resolution and direct the domain name (such as abc.com) to CNAME address A.
Which of the following is a NOT correct description of modifying domain name resolution?

If your domain name (such as abc.com) is transferred to Alibaba Cloud in advance, and managed by the same Alibaba Cloud account, you can perform one-step resolution modification.

The CNAME address allocated to the domain name (such as abc.com) will point to an IP address. This IP address resolving mechanism is intelligently managed by Alibaba Cloud CDN system.

The DNS service provider used by the domain name (such as abc.com) must support intelligent resolution.

The DNS service provider used by the domain name (such as abc.com) can be companies other than Alibaba Cloud.

Q21. You are using Auto Scaling with one scaling group already created, then you want to execute a task at a specific time such as removing 1 ECS instance every night at 00:00. To achieve this, which of the following operations should be performed’? (Number of correct answers; 2)

Create a scaling rule

Create a scheduled task.

Create a new scaling group.

Create an event-triggered task.

Q22. 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)

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

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

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

Replace 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

Q23. You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.
Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.
The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.
In order to eliminate your customer’s concern, which of the following solutions should you recommend them?

Find the ECS instance that is going to be removed from the backend server pool of the SLB instancer and automatically set the weight of this ECS instance to 0. This instance will not be assigned with new requests, and will be automatically removed from the backend server pool after existing tasks are completed.

First, insert a script into the image for creating the ECS instance Second, make the script run automatically when the operating system in this ECS instances is about to shut down. This script contains the processing logic that can ensure the instance finish all the remaining tasks before shutting down.

Find the ECS instance that is going to be removed from the backend server pool of the SLB instance, and manually remove this instance from the backend server pool Applications running on this ECS instance will normally return results, but this instance will not be assigned with new requests.

Use the Lifecycle Hook function embedded m Auto Scaling Define a suitable timeout and a web hook to do the necessary work before the instance is removed.

Q24. A company launched its online service just a year ago. It uses five ECS instances and does not have a full-time system administrator Over the last six months, the company’s system has encountered various security problems Several high-risk vulnerabilities were exploited by hackers, leading to leakage of the company’s confidential dat
a. Which of the following Alibaba Cloud products can be used to quickly resolve this problem?

Q25. To meet business requirements, a user requires that the backend server of an SLB instance include a primary ECS instance and a secondary ECS instance. When the primary instance is working properly, the traffic is only forwarded to the primary ECS, when the primary instance is down, traffic is switched to the standby instance. In this case, you can create an active/standby server group on the backend of the SLB instance Which kind of listener supports this feature? (Number of correct answers: 2)

HTTPS

HTTP

UDP

TCP
