1. After creating an RDS for MySQL read-only instance, which of the following CAN NOT be performed by the read-only instance in RDS management console?

Parameter configuration

Specification change

SQL log auditing

Intranet/Internet switchover

2. After stopping an Alibaba Cloud Elastic Compute Service (ECS) instance, since the ECS instance is stopped, you will not be charged for anything related to that ECS instance until you start the instance again regardless of which region the instance is located in.

True

False

3. Which of the following scenarios can be done using Alibaba Cloud Express Connection? (Number of correct answers: 2)

Intranet communication between VPCs and Smart Access Gateway in customers different branch offices

Intranet communication between a VPC and servers in an external IDC

Intranet communication between two VPCs in different accounts and different CIDR Blocks

Intranet communication between two VPCs under the same account in the same region

4. Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies It supports adding an existing ECS instance into the scaling group but imposes certain requirements on instance region.

In this case, which of the following statements is true?

The instance and the scaling group must be in the same region and zone.

The instance and the scaling group must be in the same region but not necessarily the same zone.

Each scaling group can span up to two regions. After adding the ECS instance, the number of regions of all the ECS instances in the scaling group must be no greater than two.

The instance and the scaling group can be in different regions and zones.

5. You have created two Alibaba Cloud VPCs in two different regions. To establish communication between these two VPCs via the Intranet, you can________.

Use the VRouter to create a new route table to enable the communication

Use CEN to establish communication between VPCs

Create a new access rule through the Security Group to enable the communication

No operation is needed, as VPCs under the same account are connected through the Intranet by default

6. All RDS for MySQL backups are full backups.

True

False

7. When a customer uses Alibaba Cloud Object Storage Service (OSS) service and finds there exist an amount of Internet downstream traffic, he/she can use Alibaba Cloud Content Delivery Network (CDN) service to reduce the traffic cost.

Because the Internet traffic cost of CDN is lower than that of OSS, moreover, the back-to-source traffic cost from CDN to OSS is also lower than a user access to OSS directly.

True

False

8. 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)

One 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.

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

Before 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.

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

9. Object Storage Service (OSS) supports access logging. A bucket owner can activate access logging for their buckets in the OSS management console. When access logging is activated for bucket A, OSS automatically accesses the request logs for this bucket (in hours) and generates and writes an object to the user-specified bucket B according to certain naming rules .

Which of the following statements is true for OSS logging?

Buckets A and B can be separate buckets (or a single bucket) but they must belong to the same user

Buckets A and B must be the same bucket.

Buckets A and B can belong to different users.

Buckets A and B must be different buckets.

10. A new media company uses a mobile app to provide news and information services. They utilize Auto Scaling to add/reduce ECS instances dynamically to address service traffic spikes.

Based on the estimation of their service and technical personnel the company thinks they require 10 ECS instances during idle hours and 10 to 20 ECS instances (dynamically adjusted) during some busy hours, which are normally from 07:30 to 09:00 and from 18:30 to 20:00 In the scaling group; they set the "Minimum number of instances" to 10 and "Maximum number of instances" to 20.

To simplify deployment tasks and save costs, which of the following scaling modes should they choose?

Healthy mode

Scheduled mode

Fixed quantity mode

Event-triggered mode

11. For ECS and RDS instances under different Alibaba Cloud accounts but in the same region, which of the following statements is NOT correct for migrating self-built MySQL databases (running on ECS) to RDS?

The data can be imported via the Intranet

The data cannot be migrated.

The data can be imported via the public network.

The data can be imported by running mysqldump.

12. 1.Alibaba Cloud Content Delivery Network (CDN) performs content acceleration with the support of intelligent DNS resolution. The following function_________is NOT included in intelligent DNS resolution.

A user request is directed to the server nearest to the customer based on location information of the pre-configured IP section.

The intelligent DNS resolution can parse the same domain name into different IP addresses based on the IP of different visitors.

The intelligent DNS resolution supports web page content caching. A user will receive data from the origin site at first-time access, and then will be reading data from cache in subsequent requests

If a user activates mirror sites in different IDCs, intelligent DNS resolution can achieve load balancing by guiding customers in different places to different mirror sites.

13. Alibaba Cloud CloudMonitor is a service that monitors Alibaba Cloud resources and Internet functions currently provided by CloudMonitor? (Number of correct answers: 3)

Site monitoring

Customized monitoring

Custom firewall

Operation auditing

Cloud service monitoring

14. An online education website is built based on ECS. SLB and Auto Scaling, which greatly reduces resource cost, O&M cost and without compromising system stability and user experience.

Now. the website admin wants to keep the user information (such as source IP, accessed URLs, and duration on each page) for analysis to support their upcoming campaign events.

In this case, which of the following statements is NOT correct?

Let each ECS instance in the scaling group keeps the user access information it processes Thus, the data saved by these ECS instances can be accessed and analyzed at any time, making the solution not only simple, but also efficient reliable, and cost-effective.

Save user-related access information to ApsaraDB for RDS in real time or quasi real time, which can then be used for performing query and analysis.

Synchronize user-Synchronize user-related access information to ApsaraDB for Memcache in real time or quasi real time. Then, access Memcache using an application or make the data in Memcache persistent based on certain rules and then can use the persistent data for further analysis.

Synchronize user-related access information to OSS in real time or quasi real time for further use
