A challenging thing in the gaming industry is the unpredictable and fluctuating business traffic. For example, 1 ECS instance is enough to meet all business demands today; however, we may need 10 ECS instances tomorrow.
In this situation, it is difficult to predict the number of ECS instances required. If we use too few ECS instances, we may not be able to cope with business peaks; whereas if we use too many ECS instances, we may introduce unnecessary costs.
On Alibaba Cloud, _______________ is the best product portfolio to cope with the gaming scenario
described above.
- A . Server Load Balancer (SLB) + Elastic Compute Service (ECS) + ApsaraDB for RDS + Auto Scaling
- B . Server Load Balancer (SLB) + Elastic Compute Service (ECS) + ApsaraDB for RDS
- C . Elastic Compute Service (ECS) + Auto Scaling
- D . Elastic Compute Service (ECS)
A
Explanation:
In this scenario, a combination of Server Load Balancer (SLB), ECS, ApsaraDB for RDS, and Auto Scaling is ideal. SLB distributes incoming traffic across multiple ECS instances, ensuring high availability and reliability. Auto Scaling automatically adjusts the number of ECS instances based on demand, managing costs efficiently by scaling out during peak times and scaling in when demand decreases. ApsaraDB for RDS provides a managed database service that handles increasing database demands without requiring complex manual scaling. This portfolio is optimal for fluctuating gaming traffic as it ensures load balancing, scalability, and cost control.

You deployed the website on an Alibaba Cloud Elastic Compute Service (ECS) instance. After sometime, you worried that the ECS instance might be cracked by brute-force password cracking.
To address this issue, you can use Alibaba Cloud’s ___ product.
- A . Object Storage Service (oss)
- B . Cloud Monitor
- C . Server Load Balancer (SLB)
- D . Security Center
Alibaba Cloud OSS is a cloud storage service that features massive capacity, outstanding security, low cost, and high reliability. No traffic charges are applied when files are uploaded to OSS via the
management console or using Open API.
- A . TRUE
- B . FALSE
A
Explanation:
Alibaba Cloud OSS does not charge for data ingress, meaning there are no traffic charges for uploading files to OSS, whether through the management console or Open API. However, traffic charges may apply for data egress, i.e., downloading files from OSS.

Alibaba Cloud will check source IP addresses that connect to ApsaraDB for RDS through the public internet. When Alibaba Cloud Situation Awareness detects an alert reporting “a seldom-used IP address connecting to the database,” which of the following is the safest way to handle this alert?
- A . This alert does not matter and can be ignored
- B . Log on to Alibaba Cloud console, modify the IP address whitelist for authorized access to RDS, and retain the IP addresses that need to connect to RDS
- C . Modify the security group policies for ECS instances, and allow only specified IP addresses to connect to the server
- D . Log on to RDS console, and view the SQL audit logs to check whether any destructive operation has been performed. If no, you do not need to handle the alert
B
Explanation:
The safest response to a seldom-used IP alert connecting to ApsaraDB for RDS is to adjust the IP whitelist to allow only trusted IP addresses. By limiting the IP addresses in the whitelist, unauthorized or unfamiliar IP addresses cannot access the database. This approach provides direct
control over access to RDS and minimizes potential security risks. Checking SQL audit logs (as suggested in option D) is useful but not sufficient on its own for a comprehensive security response.

Alibaba Cloud Object Storage is suitable for storing unstructured data such as pictures and videos.
- A . True
- B . False
A
Explanation:
Alibaba Cloud Object Storage Service (OSS) is ideal for storing unstructured data, including media files such as pictures, videos, and documents. OSS offers scalable storage, high durability, and easy access, making it well-suited for handling large volumes of unstructured data.
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
D
Explanation:
A read-only RDS instance is a replica of the primary RDS instance that can handle read requests and increase the read capability of the database system. A read-only RDS instance inherits the network type (intranet or internet) of the primary RDS instance and cannot switch between them. Therefore, option D is the correct answer.

An enterprise uses a public cloud service to lease several virtual machines and places these virtual machines in an isolated virtual network. They have full control over their virtual network, including choosing their IP address range, specifying the CIDR block, configuring the routing table, and gateway, etc.
In Alibaba Cloud, the _____________ can work as described above.
- A . SDN service
- B . NFV service
- C . VPC service
- D . VPN service
C
Explanation:
In Alibaba Cloud, a Virtual Private Cloud (VPC) provides isolated virtual networking environments where users can configure their own IP address ranges, CIDR blocks, routing tables, gateways, and other network elements. This functionality is critical for users who require an isolated, customizable network environment for their virtual machines in the public cloud. SDN (Software-Defined Networking) and NFV (Network Functions Virtualization) are underlying technologies, while VPN offers secure connectivity but not full virtual network management.

As a concept stem from cloud computing, cloud storage service provides on-demand storage and data services to users through a unified interface Which of the following characteristics about cloud storage are correct? (Number of correct answers: 4)
- A . Management and maintenance: To prevent emergent service termination, users need to know the underlying detail like how the data is archived in the resource pool.
- B . Service on demand Cloud storage has a huge resources pool, users can apply for and use the resources on demand.
- C . High reliability and availability: Provides very high reliability and availability through technologies like 3 redundant copies, automatic failure recovery, etc.
- D . Ultra-large scale: Data storage can reach TB or even PB level
- E . Transparent service: Provides the service through a single SDK
- F . High scalability Storage capacity can be dynamically scaled to meet the needs.

Explanation:
Alibaba Cloud Object Storage OSS can upload object files through the console.
What is the largest object file uploaded? (Single answer)
- A . 1GB
- B . 5GB
- C . 10GB
- D . 1TB
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs.
- A . True
- B . False
A
Explanation:
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs. Alibaba Cloud CDN is a global network of points of presence (POPs) that are distributed across the globe. Alibaba Cloud CDN serves to reduce back-to-origin traffic. This in turn prevents network congestion and ensures that content is delivered with minimal latency across regions in various use cases 1. Alibaba Cloud CDN caches resources from your origin servers on POPs located across the globe. Whenever customers access your resources, the resources are served from the nearest POP instead of the origin server. This helps prevent lengthy back-to-origin requests and reduces loads on origin servers, delivering better experience to your customers and reducing back-to-origin costs 1. Alibaba Cloud CDN also provides IPv6 support on some POPs 1. You can use Alibaba Cloud CDN to accelerate access to Object Storage Service (OSS). If you directly access OSS resources, the access speed varies based on the region in which the buckets are located and is limited by the outbound bandwidth of OSS2. The Internet traffic cost of CDN is lower than that of OSS, and the back-to-source traffic cost from CDN to OSS is also lower than a user access to OSS directly2. Therefore, using CDN can reduce the traffic cost of OSS.
