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?

A. Parameter configuration

B. Specification change

C. SQL log auditing

D. Intranet/Internet switchover

A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience).

Thus, you use Auto Scaling to elastically adjust computing resources. Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely.

In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)

A. Cloud monitor and event-triggered task: Dynamically adds ECS instances during resource shortage and reduces ECS instances during idle hours by monitoring the CPU utilization rate and workload

B. Scheduled task: Increases the number of ECS instances to 40 on the first day of the holidays and reduce the number to 20 after the holidays.

C. Manual mode: Set the minimum number of instances to 40 on the first day of the holidays and change the number to 20 after the holidays.

D. Healthy check mode: Ensures that all the current ECS instances in scaling groups are working correctly to meet user access requests.

Compared with traditional physical servers, upgrading an ECS instance is much easier. Which of the following statements about upgrading an ECS instance is false?

A. You can upgrade the CPU, memory, and bandwidth.

B. Upgrading the configuration of the ECS instance requires no' redeployment or data migration.

C. Upgrading network bandwidth does not require the ECS instance to restart.

D. You can change an instance's operating system without rebooting.

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?

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

B. Buckets A and B must be the same bucket.

C. Buckets A and B can belong to different users.

D. Buckets A and B must be different buckets.

The daily PV volume of a community website is as high as 20 million. The applications of the website are deployed on ECS instances while logs are stored on the data disks of a single ECS instance.

Now, the website wants to extend the log retention period to 24 months and ensure that logs can be quickly downloaded when needed. The current data disks they have can only help retain three months of logs In this case, ________ is the ideal solution for solving the log retention issue.

A. CDN

B. Container Service

C. OSS

D. ApsaraDB for RDS

Alibaba Cloud Object Storage Service (OSS) provides multiple file uploading modes for different scenarios, which are___________. (Number of correct answers: 2)

A. Direct upload from the OSS management console no matter how large the file is

B. Uploading using the API

C. Directly copying to/from OSS using portable disks

D. Upload using the SDK

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

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

B. Use CEN to establish communication between VPCs

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

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

OSS supports multi-part uploading for large files, namely dividing a large file into multiple parts and uploading them in order. This function is suitable for scenarios such as uploading large files or uploading files with poor connectivity.

After completing all the multi-part uploading tasks, if you forget to invoke the "Complete Multipart Upload" interface, there will be fragment files left in OSS, occupying bucket storage space-To facilitate deleting those files, OSS provides the________function.

A. OpenAPI batch deletion

B. Online batch deletion

C. Bucket clearing

D. Fragment management

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?

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

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

C. 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.

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

An enterprise hosts their servers (include both Linux and Windows servers) in a traditional IDC Every night hackers with IP addresses from many countries try to crack the password of their servers, making the administrator terribly worried about this However because of work requirements the remote management port of these servers must be opened to public network.

The administrator heard that Alibaba Cloud has solutions that can help customers improve the security of their systems Therefore, he/she wants to migrate the system to Alibaba Cloud. Which of the following functions should the administrator activate in Alibaba Cloud to reduce the possibility of brute force password cracking?

A. Cloud Firewall

B. Anti-DDoS Origin Basic Edition

C. CloudMonitor

D. Security Center
