Question 1

Alibaba Cloud's Object Storage Service (OSS) can be used to store a large amount of data, but there is still a maximum number of files in a single bucket.



Answer : B

There is no limit on the number of objects that can be stored in a single OSS bucket in Alibaba Cloud. OSS is designed to support massive data storage, allowing users to store an unlimited number of files within a bucket. The only limitations are the bucket storage capacity and account-level quotas.


Question 2

Alibaba Cloud Object Storage is suitable for storing unstructured data such as pictures and videos.



Answer : A

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.


Question 3

After activating an SLB, it will be assigned an IP address. The SLB will keep this IP address until it is released.



Answer : A

Alibaba Cloud SLB instances are assigned a public or private IP address when created, and this IP remains unchanged for the life of the SLB instance. The IP address will only be released when the SLB instance itself is deleted.


Question 4

In Auto Scaling, a scaling group refers to the collection of ECS instances deployed with the same applications, where these ECS instances can be charged by monthly subscription or Pay-As-You-Go. For scenarios with abrupt service traffic change, Pay-As-You-Go ECS instances can meet service requirements while minimizing cost. For monthly subscription ECS instances, you can manually add the idle instances to the scaling group to take full advantage of idle resources.



Answer : A

Auto Scaling in Alibaba Cloud supports both Pay-As-You-Go and monthly subscription ECS instances within a scaling group. Pay-As-You-Go instances provide flexibility during traffic surges, while idle monthly subscription instances can be added manually to optimize costs and resource usage.


Question 5

All versions of Alibaba Cloud RDS use master-slave mode to ensure high availability. When the master database fails, RDS will switch to the standby database within 30 seconds.



Answer : A

Alibaba Cloud RDS uses a master-slave or primary-replica architecture to provide high availability. In the event of a master database failure, automatic failover to the standby instance generally occurs within 30 seconds, helping to minimize downtime and maintain service continuity.


Question 6

On an Alibaba Cloud Elastic Compute Service (ECS) instance, if you change the MAC address of the NIC within the operating system, this may result in network connection failure.



Answer : A

Modifying the MAC address of an ECS instance's NIC can cause network disconnection issues because Alibaba Cloud's VPC network infrastructure relies on consistent NIC configuration. Changing the MAC address may prevent the instance from being identified correctly on the network.


Question 7

A route table refers to the list of routing entries on a VRouter in an Alibaba Cloud VPC. You can create/delete any route tables in a VPC.



Answer : B

In Alibaba Cloud VPCs, only custom route tables can be created and deleted by users. The default route table associated with each VPC cannot be deleted, although custom routing entries within it can be modified. This limitation ensures the integrity of essential VPC networking components.
