Q14. 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

Q15. Different Alibaba Cloud VPCs are completely isolated from each other.
By default, the VPCs cannot communicate with each other over Intranet, but you can establish VPN connections via the Internet to achieve interconnection between VPCs.

True

False

Q16. Which of the following scenarios can be done using Alibaba Cloud Express Connection? (Number of correct answers: 2)

Intranet communication between VPCs and Smart Access Gateway in customers different branch offices

Intranet communication between a VPC and servers in an external IDC

Intranet communication between two VPCs in different accounts and different CIDR Blocks

Intranet communication between two VPCs under the same account in the same region

Explanation
Alibaba Cloud Express Connect is a service that enables high-bandwidth, reliable, secure, and private connections between different networks, such as VPC networks across regions, Alibaba Cloud accounts, and on-premise data centers1. It supports different connection methods, such as physical connections, virtual border routers, and Express Cloud Connect1.
Scenario A: Intranet communication between VPCs and Smart Access Gateway in customers different branch offices. This scenario can be achieved by using Express Cloud Connect, which is based on the hardware capacities of Smart Access Gateway and provides SD-WAN capabilities1. Express Cloud Connect allows you to connect your branch offices to Alibaba Cloud through a dedicated partner backbone network, and access VPC networks in all regions1.
Scenario B: Intranet communication between a VPC and servers in an external IDC. This scenario can be achieved by using physical connections, which are dedicated network connections between on-premise data centers and VPC networks1. You can lease a line from your ISP or work with an Alibaba Cloud partner to establish a physical connection to Alibaba Cloud1. This way, you can access VPC networks in all regions with high bandwidth and low latency1.
Scenario C: Intranet communication between two VPCs in different accounts and different CIDR Blocks. This scenario can be achieved by using peering connections, which are logical connections that enable communication between VPC networks2. Peering connections support cross-region and cross-account scenarios, and allow you to connect VPC networks with different CIDR blocks2. However, peering connections are not part of Alibaba Cloud Express Connect, but a separate service called Cloud Enterprise Network2.
Scenario D: Intranet communication between two VPCs under the same account in the same region. This scenario can also be achieved by using peering connections, which are logical connections that enable communication between VPC networks2. Peering connections support intra-region and same-account scenarios, and allow you to connect VPC networks with different CIDR blocks2. However, peering connections are not part of Alibaba Cloud Express Connect, but a separate service called Cloud Enterprise Network2.

Q17. Different Alibaba Cloud VPCs are completely isolated from each other.
By default, the VPCs cannot communicate with each other over Intranet, but you can establish VPN connections via the Internet to achieve interconnection between VPCs.

True

False

Q18. The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet).

True

False

Q19. Which of the following ports does RDS for MySQL listen on by default?

Port 8080

Port 3306

Port 3060

Port 3600

Q20. The backend server pool of an Alibaba Cloud SLB contains multiple ECS instances, which may have different service capacities. To exploit the different service capacities of backend ECS instances, which of the following statements is correct?

Choose Weighted Round Robin mode to set higher weights to ECS instances with higher capacities The higher the weight of the backend ECS instance the higher chance that the instance will receive requests.

SLB cannot assign more requests to certain ECS instances.

Choose Round-Robin model and ECS instances with higher capacities will surely be assigned with more requests.

Choose Weighted Least-Connection mode, and ECS instances with higher capacities will surely be assigned with more requests.

Q21. Alibaba Cloud provides comprehensive security protection covering networks, hosts, applications, databases, and content for on-cloud clients. Users using Alibaba Cloud services only need to focus on their own services, without the need to pay any attention to security protection issues.

True

False

Q22. 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.

Q23. When the “‘Obtain the Visitor’s Real IP Address” function is enabled in Alibaba Cloud SLB For layer 7 services, you can obtain the real IP addresses of visitors through the______________field in HTTP header
