Which of these are suitable use cases for Alibaba Cloud's ApsaraDB for Redis service? (Number of correct answers: 3)
Correct Answer:
A, C, D
Explanation
Migrating a physical server to ECS requires creating a custom image first. Using a third-party tool to capture the existing system, uploading it to Alibaba Cloud, and then launching ECS instances from that image is the standard approach. This avoids manual reconfiguration of the entire application environment. Other methods like manual installation or direct copying would be much more time consuming and error prone.
Assume that a company uses ApsaraDB for PolarDB. The company commonly queries users based on their basic information, including: addresses, company names, and ID numbers. In this scenario, what is the best practice for creating a database index (or indexes)?
Correct Answer:
A
Explanation
This scenario needs serverless workflow to orchestrate the video processing pipeline, ECS to handle the actual video preprocessing work at scale, and log service to monitor and track the processing jobs. Serverless Workflow provides the orchestration, ECS provides the compute power for parallel processing, and Log Service provides visibility into the operations. This combination minimizes operational overhead while keeping costs reasonable.
Which of the following permission control policies does Object Storage Service (OSS) provide for access to objects stored in a bucket? (Number of correct answers: 4)
Correct Answer:
A, C, D, F
Explanation
SSL encryption does increase CPU usage due to the encryption and decryption overhead. The recommendation is to enable SSL for external network connections where security is critical, but skip it for internal network links since they are already protected within your VPC. This balances security needs with performance impact. Enabling SSL everywhere wastes resources on connections that don't need the extra protection.
Which of the following cloud services can be integrated with Alibaba Cloud KMS (Key Managed Service)? (Number of correct answers: 3)
Correct Answer:
A, B, C
Explanation
In Alibaba Cloud Log Service, certain fields cannot be empty because they are essential for log identification and routing. Topic, Time, Source, and Tags are all required fields that must contain values. Content is the only field that can be empty since a log entry might not have message content but still needs the metadata fields to be valid and processable by the system.
In order to have your applications interact with Alibaba Cloud RabbitMQ, you need to create related MQ resources first. Which of the following resources must be created? (Number of correct answers: 3)
Correct Answer:
B, C, E
Explanation
Using Container Registry's built in integration with GitHub is the simplest approach. You connect your registry to your GitHub repository, upload your code and Dockerfile, and set up an automated build rule. Then every time you update the code, the image rebuilds automatically. This eliminates manual image building steps and keeps everything in sync without extra tooling or maintenance burden.
A job hunting website stores user's resumes in Object Storage Service (OSS) The current resume upload process is as follows:
7. Users upload resumes
2. The server responds to the upload request
3. The resume is uploaded to the server
4. 1 he server uploads the resume to OSS
Which of the following methods can be used to upload objects to OSS without requiring Step 3?
Correct Answer:
D
