NO.25 An enterprise hosts their servers (include both Linux and Windows servers) in a traditional IDC Every night hackers with IP addresses from many countries try to crack the password of their servers, making the administrator terribly worried about this However because of work requirements the remote management port of these servers must be opened to public network.
The administrator heard that Alibaba Cloud has solutions that can help customers improve the security of their systems Therefore, he/she wants to migrate the system to Alibaba Cloud. Which of the following functions should the administrator activate in Alibaba Cloud to reduce the possibility of brute force password cracking?

CloudMonitor

Security Center

NO.26 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?

Find 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.

First, 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.

Find 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.

Use 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.

NO.27 Many websites have suffered DDoS attacks of different volumes. Therefore, accurate understanding of DDoS attacks is critical to website security protection. Which of the following statements about DDoS attacks is the MOST accurate?

The main purpose of a DDoS attack is to prevent the target server from providing normal services. Currently, the DDoS attack is one of the strongest and most indefensible website attacks.

A DDoS attacks crack the server’s logon password by means of a massive number of attempts.

DDoS attacks primarily target databases.

The data can be imported via the public network.

The data can be imported by running mysqldump.

NO.30 An online education website is built based on ECS. SLB and Auto Scaling, which greatly reduces resource cost, O&M cost and without compromising system stability and user experience.
Now. the website admin wants to keep the user information (such as source IP, accessed URLs, and duration on each page) for analysis to support their upcoming campaign events In this case, which of the following statements is NOT correct?

Let each ECS instance in the scaling group keeps the user access information it processes Thus, the data saved by these ECS instances can be accessed and analyzed at any time, making the solution not only simple, but also efficient reliable, and cost-effective.

Save user-related access information to ApsaraDB for RDS in real time or quasi real time, which can then be used for performing query and analysis.

Synchronize user-Synchronize user-related access information to ApsaraDB for Memcache in real time or quasi real time. Then, access Memcache using an application or make the data in Memcache persistent based on certain rules and then can use the persistent data for further analysis.

Synchronize user-related access information to OSS in real time or quasi real time for further use

NO.31 Names of the files in each OSS bucket must be unique Also, they can be renamed.

True

False

NO.32 Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.

True

False

NO.33 A Virtual Private Cloud (VPC) is an isolated network environment that is completely isolated from each other The following statements about VPC are correct_________. (Number of correct answers: 2)

Each VPC has an independent tunnel ID, and a tunnel ID corresponds to a virtualized network.

ECS instances in a VPC use security group firewalls for Layer 2 network access control.

Subnets can be divided like the traditional network environment. Different cloud servers within each subnet are connected by the same router and different subnets are interconnected by switches.

The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside.

NO.37 A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience). Thus, you use Auto Scaling to elastically adjust computing resources.

In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)

Cloud monitor and event-triggered task: Dynamically adds ECS instances during resource shortage and reduces ECS instances during idle hours by monitoring the CPU utilization rate and workload

Scheduled task: Increases the number of ECS instances to 40 on the first day of the holidays and reduce the number to 20 after the holidays.

Manual mode: Set the minimum number of instances to 40 on the first day of the holidays and change the number to 20 after the holidays.

Choose an ECS instance from VPC and make it as the bastion host And then, apply an EIP and bind it to this ECS instance. After that the administrator can manage other ECS instances through this bastion host.

Modify the VPC Security Group policy, to allow access from the Internet.
