Correct Answer: C

Alibaba Cloud OSS (Object Storage Service) provides extremely high data reliability, typically around 99.99999999%, due to its multi-replica and distributed architecture, ensuring data durability and resilience against single points of failure (SPOF). OSS is designed to store massive amounts of data with high redundancy, making it a preferred choice for businesses that require high reliability and fault tolerance in cloud storage.

Question No. 2

You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.

Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.

The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.

In order to eliminate your customer's concern, which of the following solutions should you recommend them?

AFind the ECS instance that is going to be removed from the backend server pool of the SLB instancer and automatically set the weight of this ECS instance to 0. This instance will not be assigned with new requests, and will be automatically removed from the backend server pool after existing tasks are completed.

BFirst, insert a script into the image for creating the ECS instance Second, make the script run automatically when the operating system in this ECS instances is about to shut down. This script contains the processing logic that can ensure the instance finish all the remaining tasks before shutting down.

CFind the ECS instance that is going to be removed from the backend server pool of the SLB instance, and manually remove this instance from the backend server pool Applications running on this ECS instance will normally return results, but this instance will not be assigned with new requests.

DUse the Lifecycle Hook function embedded m Auto Scaling Define a suitable timeout and a web hook to do the necessary work before the instance is removed.

Show Answer

Correct Answer: D

According to the Alibaba Cloud Auto Scaling documentation1, the Lifecycle Hook feature allows you to perform custom operations on instances that are added to or removed from a scaling group. You can define a lifecycle hook to specify a timeout period and a web hook URL. When an instance is about to be removed, Auto Scaling sends a notification to the web hook URL and waits for a response. During the timeout period, you can perform the necessary operations on the instance, such as gracefully shutting down the service, backing up the data, or sending a custom notification. After the operations are completed, you can send a response to the web hook URL to confirm the removal of the instance. This way, you can ensure that the instance is removed without affecting the user experience or causing data loss. Therefore, option D is the best solution to eliminate the customer's concern.

Question No. 3

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.

Show Answer

Correct Answer: C

OSS (Object Storage Service) is a secure, cost-effective, and highly reliable cloud storage service that allows you to store, back up, and archive any amount of data in the cloud1. OSS is ideal for storing logs, as it provides 99.9999999999% (12 nines) durability and 99.995% availability or service continuity1. OSS also supports lifecycle management, which allows you to automatically delete or transition objects to lower-cost storage classes based on your predefined rules2. OSS offers four tiers of storage: Standard, Infrequent Access, Archive, and Cold Archive. Each tier is cost-optimized for specific storage patterns1. The Archive and Cold Archive tiers are suitable for storing infrequently accessed data, such as logs, for a long time. The Archive tier offers data retrieval time within one minute, while the Cold Archive tier offers expedited data retrieval time within an hour1. Therefore, OSS can help the website extend the log retention period to 24 months and ensure that logs can be quickly downloaded when needed.

CDN (Content Delivery Network) is a distributed network that delivers content to users based on their geographic locations, the origin sites, and the content delivery nodes3. CDN is mainly used for content distribution, such as static web pages, images, videos, and downloads3. CDN is not suitable for storing logs, as it does not provide data durability or lifecycle management.

Container Service is a high-performance and scalable container application management service that enables you to use Docker and Kubernetes to manage the lifecycle of containerized applications4. Container Service is mainly used for deploying and orchestrating microservices, serverless applications, and big data applications4. Container Service is not suitable for storing logs, as it does not provide data durability or lifecycle management.

ApsaraDB for RDS (Relational Database Service) is a stable and reliable online database service that supports MySQL, SQL Server, PostgreSQL, MariaDB, and PPAS5. ApsaraDB for RDS is mainly used for storing and processing structured data, such as user information, transaction records, and product catalogs5. ApsaraDB for RDS is not suitable for storing logs, as it is more expensive and less scalable than OSS.

Question No. 4

An enterprise built an isolated network environment by using Alibaba Cloud VPC and connected this VPC to a traditional data center via VPN. This allows the enterprise to seamlessly migrate data from its traditional data center to Alibaba Cloud.

Now they need to receive user requests from the Internet and assign these requests to multiple ECS instances inside the VPC by using SLB. Which of the following statements are correct? (Choose two.)

AThey can create an SLB instance in the VPC, and mount ECS instances within the VPC to this SLB instance. Then, use a jump server to receive external requests and direct these requests to SLB to forward them to backend ECS instances.

BThey can create an SLB instance with an Internet IP address, and mount ECS instances within the VPC to this SLB instance. The public SLB will be used to receive external requests. As a result, requests from the Internet will be transferred to backend ECS instances within the VPC.

CThey can create an SLB instance in the VPC, and mount ECS instances within the VPC to this SLB instance. Then, bind an EIP to the SLB, so that this SLB instance can receive requests from the Internet and assign these requests to the backend ECS instances.

DThey can create an SLB instance with an Internet IP address, and mount ECS instances within the VPC and servers of the traditional data center to this SLB instance. The public SLB will be used to receive external requests. As a result, requests from the Internet will be transferred to backend ECS instances within the VPC and servers of the traditional data center.

Show Answer

Correct Answer: B, C

To enable Internet access for ECS instances in a VPC, Alibaba Cloud users can use a public SLB with an Internet IP address (Option B) or an SLB with an Elastic IP (EIP) attached (Option C). Both methods allow the SLB instance to receive external requests and forward them to ECS instances within the VPC. Option A is incorrect because it would require a more complex setup without direct Internet access. Option D is incorrect as SLB does not support directly mounting servers from an on-premises data center.

Question No. 5

Alibaba Cloud Object Storage Service (OSS) is a massive, highly available, secured, and cost-effective storage service. One of the special characteristics of OSS is its superior data reliability due to its underlying backup technology and policies. Which of the following statements about OSS backup is correct?

AOSS supports 3 internal data copies, so the data can be manually recovered should there be any problem.

BCustomers have to safeguard their own data. OSS provides various backup interfaces to facilitate off-site backups.

COSS leverages RAID0+1 configuration of its underlying physical hard disks. There is no impact even if 2 hard disks were to fail simultaneously.

DOSS supports 3 internal data copies; no human intervention is required to recover the data when anything goes wrong.

Show Answer

Correct Answer: D

Alibaba Cloud OSS automatically maintains three copies of each data object to ensure data reliability and redundancy. This setup allows OSS to recover data automatically without human intervention in case of hardware or system failures, ensuring high data durability.
