Therefore, you can use Alibaba Cloud_______to solve this issue.
- A . Object Storage Service (oss)
- B . SSD cloud disk
- C . Apsara DB for RDS
- D . Table Store
Which of the following is not the potential cause of latency on an RDS read-only instance? (Single answer)
- A . The load on this read-only instance is significant.
- B . There exists significant load on the ECS that is connected to this read-only instance
- C . The specification of this read-only instance is too low.
- D . This read-only instance’s master instance is performing a lot of write operations.
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)
- A . Create a new scaling group.
- B . Create a scaling rule.
- C . Create a scheduled task.
- D . Create an event-triggered task.
A large shopping mall deploys a new video surveillance system. The five-floor building in which the mall is located has installed 35 HD cameras to monitor the major exits. The surveillance system is deployed on an ECS instance, which has four 2 TB data disks to store video data.
However, video data grows so rapidly that the engineers find the ECS will run out of storage space within 2 weeks.
In this case, ___________ product is thought to be the best solution for addressing the storage
challenge while ensuring quick access to historical video data when needed.
- A . Container Service
- B . ECS
- C . OSS
- D . CDN
C
Explanation:
Alibaba Cloud OSS (Object Storage Service) is the ideal solution for storing large volumes of video data generated by a surveillance system. OSS provides scalable, secure, and cost-effective storage that can accommodate growing data needs without the space limitations of local ECS disks.
Additionally, OSS enables easy access to historical data when required, making it well-suited for video storage in use cases like surveillance.

Object Storage Service (OSS) supports sub accounts, and you can allocate access permissions to different buckets for each sub account.
- A . True
- B . False
A
Explanation:
Object Storage Service (OSS) supports sub accounts, which are the accounts that belong to a parent account and share the resources of the parent account. You can allocate access permissions to different buckets for each sub account by using bucket policies or RAM policies. Bucket policies are the access control policies that are attached to buckets and specify the permissions that other users have on the resources in the buckets. RAM policies are the access control policies that are attached to RAM users or RAM user groups and specify the permissions that the RAM users or RAM user groups have on the OSS resources.

Elastic Compute Service (ECS) instances you created in different zones within the same region are not interconnected with each other through the Intranet by default.
- A . TRUE
- B . FALSE
A
Explanation:
By default, ECS instances in different zones within the same region are not interconnected via the Intranet. To enable communication between instances across zones, you would need to configure a VPC or use other network configurations. This setup provides isolation and flexibility in managing network traffic within different zones.

There are scheduled tasks and event-triggered tasks in Auto Scaling. Regarding event-triggered tasks, which of the following metrics are supported for this type of task? (Choose four.)
- A . CPU workload
- B . Memory utilization rate
- C . Average system workload
- D . Inbound and outbound traffic
- E . Disk IOPS
A, B, D, E
Explanation:
Auto Scaling in Alibaba Cloud supports event-triggered tasks based on CPU workload, memory utilization rate, inbound and outbound traffic, and Disk IOPS as key metrics for scaling decisions. Average system workload (option C) is not a directly supported metric, making options A, B, D, and E correct. These metrics allow Auto Scaling to respond to real-time performance needs.

Cloud computing adopts a common model in Distributed System. It distributes a computing task to the resource pool (comprised of a large number of computers). Elastically utilize the resource pool can allow applications to obtain computing capacity, storage space, and message services according to the needs.
Which of the following statements are correct about cloud computing? (Number of correct answers: 4)
- A . Large scale
- B . High availability
- C . Service on demand
- D . Versatility
- E . Container based
- F . Only supports single tenant
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
B
Explanation:
CEN is a service that allows you to create a global network for rapidly building a distributed business system with a hybrid cloud computing solution. CEN enables you to build a secure, private, and enterprise-class interconnected network between VPCs in different regions and your local data centers 1. CEN uses transit routers deployed in different regions to build a full-mesh network on top of the Alibaba Cloud global transmission network. CEN enables global network communication: The two transit routers can be connected through multiple highly available and highly reliable lines2. To establish communication between two VPCs in different regions via the intranet, you can use CEN to attach the VPCs to the transit routers in their respective regions, and then create a bandwidth plan to allocate bandwidth resources for inter-region connections3. This way, you can avoid the complexity and cost of setting up VPN or Express Connect connections between the VPCs, and enjoy the benefits of CEN, such as large-scale and on-demand networking, simplified network topology, flexible management, globally connected network, shortest-path algorithm, high redundancy, automatic route learning and advertisement, and bandwidth sharing and management2.

Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.
- A . True
- B . False
B
Explanation:
Alibaba Cloud Elastic Compute Service (ECS) instances in different security groups are isolated from each other by default, but they can communicate with each other if the security group rules allow it. A security group is a virtual firewall that controls the inbound and outbound traffic of ECS instances. You can configure security group rules to specify which IP addresses, protocols, and ports can access the ECS instances in a security group. You can also authorize other security groups to access the ECS instances in a security group, which enables cross-security group communication.
