NO.37 Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.

True

False

NO.38 To meet business requirements, a user requires that the backend server of an SLB instance include a primary ECS instance and a secondary ECS instance. When the primary instance is working properly, the traffic is only forwarded to the primary ECS, when the primary instance is down, traffic is switched to the standby instance.

HTTPS

HTTP

UDP

TCP

Site monitoring

Customized monitoring

Custom firewall

NO.40 Many of Alibaba Cloud services provide highly reliable data storage capacity. For example, Object Storage Service (OSS) promises that its data reliability is no less than 99 99999999%. This high data reliability is solely achieved by RAID 0+1 redundancy technology.

True

False

NO.41 You would like to deploy your applications on Alibaba Cloud to meet requirements including cost reduction, improving service availability, fast deployment- and redundant backup Alibaba Cloud_________products can help meet these requirements (Number of correct answers 3)

Elastic Compute Service (ECS) image achieve efficient and convenient deployment.

Utilizing Content Delivery Network (CDN) can meet the demands for redundant backup.

Utilizing Server Load Balancer (SLB) and ECS instances can improve data reliability.

Elastic Compute Service (ECS) snapshot satisfies the needs of rapid recovery of applications and data.

Reasonable selection of Regions/Zones meets the location needs of application deployment as well as the demands for redundantly backup critical business applications and data.

NO.42 When using Alibaba Cloud SLB to forward layer 7 (HTTP) service requests. SLB will replace the IP address in the HTTP header file to forward requests.
Therefore the source IP address that can be seen on the backend ECS instance is the IP address of SLB instead of the clients real IP address.

True

False

NO.43 RDS provides whitelist access policies. You can set permitted IP addresses and IP network segments to effectively prevent hackers from attacking the server by port scanning.

True

False

NO.44 The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs.

True

False

NO.45 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.46 Auto Scaling can automatically adjust the number of ECS instances based on user-defined scaling rules to meet service needs. If a user cannot predict service changes or does not have enough history data, he/she can still use dynamic scaling mode to automatically add/remove ECS instances based on certain CloudMonitor performance metrics (such as the CPU utilization rate)

True

False

NO.47 Which of the following statements is most accurate about the Data Transmission Service (DTS) database migration function?

Supports database schema replication between instances.

Supports warning when source and destination has some unresolved conflict found.

Supports all of the above functions.

Supports migrating MySQL databases from external sources.

NO.48 A popular worldwide forum stores static resources in OSS and accelerates access using CON Users find that the speed of downloading files from the forum has been greatly improved, but uploading files is slow due to the long data transmission distance, resulting in a bad access experience In order to improve the speed of uploading files for users in this forum, so that users in different regions can have a good access experience, we recommend that the forum can________.

Activate the PCDN service

Activate OSS in different regions as file storage, and synchronize data between OSS in different regions through cross-region replication

Enable the transmission acceleration service for O: Enable OSS

Enable OSS static website hosting

NO.49 Which of the following ports does RDS for MySQL listen on by default?

Port 8080

Port 3306

Port 3060

Port 3600

NO.50 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.51 A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group He/she sets the “Minimum number of instances” to 2 and “Maximum number of instances” to 7.
After correctly configuring scaling settings, the customer adds a scaling rule “Add 6 ECS instances”, and creates a scheduled task based on this rule.
And then, the customer checks the scaling group and see it already contains 3 valid ECS instances, he/she then enables this scaling group immediately.
How many ECS instance will be added in the scaling group when the scheduled task is activated once’?

NO.52 By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved? (Number of correct answers 2)

Write requests are distributed to multiple instances.

Read requests are distributed to multiple instances.

Read/write requests to the database are separated.

Both read and write requests are distributed to multiple instance

NO.53 You have created two Alibaba Cloud VPCs in two different regions To establish communication between these two VPCs via the Intranet, you can________.

Use the VRouter to create a new route table to enable the communication

Use CEN to establish communication between VPCs

Create a new access rule through the Security Group to enable the communication

No operation is needed, as VPCs under the same account are connected through the Intranet by default

NO.54 Object Storage Service (OSS) supports access logging. A bucket owner can activate access logging for their buckets in the OSS management console. When access logging is activated for bucket A, OSS automatically accesses the request logs for this bucket (in hours) and generates and writes an object to the user-specified bucket B according to certain naming rules. Which of the following
statements is true for OSS logging?

Buckets A and B must be the same bucket.

Buckets A and B can belong to different users.

Buckets A and B must be different buckets.

You need to host server SSL certificates and client CA certificates on SLB

SLB can only host CA certificates, not SSL certificate
